CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This prospectus and the documents incorporated by reference contain "forward-looking statements" within the meaning of the Securities Act, the
Exchange Act and the Private Securities Litigation Reform Act of 1995, as amended. These "forward-looking statements" involve risk and uncertainty.
These forward-looking statements include, without limitation, statements relating to: liquidity; revenue and cost expectations and backlog; financing of
operations; oil and natural gas prices; rig counts, source and sufficiency of funds required for building new equipment; upgrading existing equipment and
additional acquisitions (if opportunities arise); impact of inflation; demand for our services; competition; equipment availability; government regulation;
debt service obligations; and other matters. Our forward-looking statements can be identified by the fact that they do not relate strictly to historical or
current facts and often use words such as "anticipate," "believe," "budgeted," "continue," "could," "estimate," "expect," "intend," "may," "plan,"
"predict," "potential," "project," "pursue," "should," "strategy," "target," or "will," or the negative thereof and other words and expressions of similar

historical trends, current conditions, expected future developments and other factors we believe are appropriate in the circumstances.
Although we believe that the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such
expectations will prove to have been correct. These forward-looking statements involve known and unknown risks, uncertainties and other factors that
may cause our actual results, performance or achievements to be materially different from actual future results expressed or implied by the forward-
looking statements. These risks and uncertainties also include those set forth under "Risk Factors" as well as, among others, risks and uncertainties
relating to:

·
availability of capital and the ability to repay indebtedness when due;

·
volatility in customer spending and in oil and natural gas prices that could adversely affect demand for our services and their associated
effect on rates;

·
loss of key customers;

·
utilization, margins and planned capital expenditures;

·
synergies, costs and financial and operating impacts of acquisitions;

·
interest rate volatility;

·
compliance with covenants under our debt agreements;

·
excess availability of land drilling rigs, pressure pumping and directional drilling equipment, including as a result of reactivation,
improvement or construction;

·
specialization of methods, equipment and services and new technologies;

·
operating hazards attendant to the oil and natural gas business;

·
failure by customers to pay or satisfy their contractual obligations (particularly with respect to fixed-term contracts);

·
difficulty in building and deploying new equipment;

·
expansion and development trends of the oil and natural gas industry;

·
weather;
iv

·
shortages, delays in delivery, and interruptions in supply, of equipment and materials;

·
the ability to effectively identify and enter new markets;

·
the ability to realize backlog;

·
strength and financial resources of competitors;

·
environmental risks and ability to satisfy future environmental costs;

·
global economic conditions;

·
adverse oil and natural gas industry conditions;

·
adverse credit and equity market conditions;

·
operating costs;

·
competition and demand for our services;

·
liabilities from operational risks for which we do not have and receive full indemnification or insurance;

·
governmental regulation;

·
ability to obtain insurance coverage on commercially reasonable terms;

·
financial flexibility;

·
legal proceedings and actions by governmental or other regulatory agencies;

·
technology-related disputes; and

·
other financial, operational and legal risks and uncertainties detailed from time to time in our filings with the SEC.
We caution that the foregoing list of factors is not exhaustive. Additional information concerning these and other risk factors is contained in our
Annual Report on Form 10-K for the year ended December 31, 2017 and subsequently filed Quarterly Reports on Form 10-Q, Current Reports on Form 8-
K and other SEC filings. You are cautioned not to place undue reliance on any of our forward-looking statements. The forward-looking statements speak
only as of the date made and, other than as required by law, we undertake no obligation to update publicly or revise any of these forward-looking
statements, whether as a result of new information, future events or otherwise. In the event that we update any forward-looking statement, no inference
should be made that we will make additional updates with respect to that statement, related matters or any other forward-looking statements. All
subsequent written and oral forward-looking statements concerning us or other matters and attributable to us or any person acting on our behalf are
expressly qualified in their entirety by the cautionary statements above.

States, and we provide services that improve the accuracy of horizontal wellbore placement. We have other operations through which we provide
oilfield rental tools in select markets in the United States, and we also manufacture and sell pipe handling components and related technology to
drilling contractors in North America and other select markets. In addition, we own and invest, as a non-operating working interest owner, in oil
and natural gas assets that are primarily located in Texas and New Mexico.

Expiration Date; Tenders
The exchange offer will expire at 5:00 p.m., New York City time, on September 7,
2018, unless we extend or earlier terminate the exchange offer. By tendering your Old
Notes, you represent to us that:

the ordinary course of your business;
· at the time of the commencement of the exchange offer, you have no
arrangement or understanding with any person to participate in the
distribution, within the meaning of the Securities Act, of the New Notes in
violation of the Securities Act;
· you are not our "affiliate," as defined in Rule 405 under the Securities Act;
and
if you are a broker-dealer that will receive the New Notes for your own account in
exchange for Old Notes that were acquired by you as a result of your market-making or
other trading activities, that you will deliver a prospectus meeting the requirements of
the Securities Act in connection with any resale of the New Notes you receive; for
further information regarding resales of the New Notes by participating broker-dealers,
see the discussion under the caption "Plan of Distribution."
2
Withdrawal; Non-Acceptance
You may withdraw any Old Notes tendered in the exchange offer at any time prior to
the expiration of the exchange offer. If we decide for any reason not to accept any Old
Notes tendered for exchange,
https://www.sec.gov/Archives/edgar/data/889900/000156459018021021/pten-424b3.htm[8/9/2018 5:29:59 PM]

pten-424b3.htm
the Old Notes will be returned to the registered holder at our expense promptly after
the expiration or termination of the exchange offer. In the case of Old Notes tendered
by book-entry transfer into the exchange agent's account at The Depository Trust
Company ("DTC"), any withdrawn or unaccepted Old Notes will be credited to the
tendering holder's account at DTC. For further information regarding the withdrawal
of tendered Old Notes, see "The Exchange Offer--Terms of the Exchange Offer;
Period for Tendering Old Notes" and "The Exchange Offer--Withdrawal Rights."
Conditions to the Exchange Offer
We are not required to accept for exchange or to issue New Notes in exchange for any
Old Notes, and we may terminate or amend the exchange offer, if any of the following
events occur prior to the expiration of the exchange offer:

the staff of the SEC;
· an action or proceeding shall have been instituted or threatened in any court or
by any governmental agency that might materially impair our ability to
proceed with the exchange offer;
· we do not receive all the governmental approvals that we deem necessary to
consummate the exchange offer; or
· there has been proposed, adopted or enacted any law, statute, rule or regulation
that, in our reasonable judgment, would materially impair our ability to

We may waive any of the above conditions in our reasonable discretion. See the
discussion below under the caption "The Exchange Offer--Conditions to the Exchange
Offer" for more information regarding the conditions to the exchange offer.
3
Procedures for Tendering Old Notes
Unless you comply with the procedures described below under the caption "The
Exchange Offer--Guaranteed Delivery Procedures," you must do one of the following
on or prior to the expiration of the exchange offer to participate in the exchange offer:
· tender your Old Notes by sending (i) the certificates for your Old Notes (in
proper form for transfer), (ii) a properly completed and duly executed letter of
transmittal and (iii) all other documents required by the letter of transmittal to
Wells Fargo Bank, National Association, as exchange agent, at one of the
addresses listed below under the caption "The Exchange Offer--Exchange
Agent"; or
· tender your Old Notes by using the book-entry transfer procedures described
below and transmitting a properly completed and duly executed letter of
transmittal, or an agent's message, as defined below under "The Exchange
Offer--Procedures for Tendering Old Notes," instead of the letter of
transmittal, to the exchange agent. For a book-
entry transfer to constitute a valid tender of your Old Notes in the exchange
offer, Wells Fargo Bank, National Association, as exchange agent, must
receive a confirmation of book-entry transfer of your Old Notes into the
exchange agent's account at DTC prior to the expiration or termination of the
exchange offer. For more information regarding the use of book-entry transfer
procedures, including a description of the required agent's message, see the
discussion below under the caption "The Exchange Offer--Book-Entry
Transfers." As used in this prospectus, the term "agent's message" means a
message, transmitted by DTC to and received by the exchange agent and
forming a part of a book-entry confirmation, which states that DTC has
received an express acknowledgment from the tendering participant stating
that such participant has received and agrees to be bound by the letter of
transmittal and that we may enforce such letter of transmittal against such
participant.

pten-424b3.htm
Guaranteed Delivery Procedures
If you are a registered holder of Old Notes and wish to tender your Old Notes in the
exchange offer, but:
· the Old Notes are not immediately available;
· time will not permit your Old Notes or other required documents to reach the
exchange agent before the expiration or termination of the exchange offer; or
· the procedure for book-entry transfer cannot be completed prior to the
expiration of the exchange offer;
then you may tender Old Notes by following the procedures described below under the
caption "The Exchange Offer--Guaranteed Delivery Procedures."
Special Procedures for Beneficial Owners
If you are a beneficial owner whose Old Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and you wish to tender your
Old Notes in the exchange offer, you should promptly contact the person in whose
name the Old Notes are registered and instruct that person to tender them on your
behalf.
Certain U.S. Federal Income Tax Considerations
The exchange of Old Notes for New Notes in the exchange offer is not expected to be
a taxable transaction for U.S. federal income tax purposes. See the discussion below
under the caption "Certain U.S. Federal Income Tax Considerations" for more
information regarding certain U.S. federal income tax consequences of the exchange
offer.
Use of Proceeds
We will not receive any cash proceeds from the exchange offer.
Exchange Agent
Wells Fargo Bank, National Association, is the exchange agent for the exchange offer.
You can find the address and telephone number of the exchange agent below under the
caption "The Exchange Offer--Exchange Agent."
4
Resales
Based on interpretations by the staff of the SEC, as set forth in no-action letters issued
to third parties, we believe that the New Notes issued in the exchange offer may be
offered for resale, resold or otherwise transferred by you without compliance with the
registration and prospectus delivery requirements of the Securities Act as long as:
· you are acquiring the New Notes in the ordinary course of your business;
· you are not participating, do not intend to participate and have no arrangement
or understanding with any person to participate, in a distribution of the New
Notes; and
· you are neither an affiliate of ours nor a broker-dealer tendering Notes
acquired directly from us for your own account.
If you are an affiliate of ours, are engaged in or intend to engage in or have any
arrangement or understanding with any person to participate in, the distribution of New
Notes:
· you cannot rely on the applicable interpretations of the staff of the SEC;
· you will not be entitled to tender your Old Notes in the exchange offer; and
· you must comply with the registration requirements of the Securities Act in
connection with any resale transaction.
Each broker-dealer that receives New Notes for its own account in exchange for Old
Notes that were acquired as a result of market-making or other trading activities must
acknowledge that it will deliver a prospectus meeting the requirements of the Securities
Act in connection with any resales of the New Notes issued in the exchange offer.
https://www.sec.gov/Archives/edgar/data/889900/000156459018021021/pten-424b3.htm[8/9/2018 5:29:59 PM]

pten-424b3.htm
Furthermore, any broker-dealer that acquired any of its Old Notes directly from us:
· may not rely on the applicable interpretation of the staff of the SEC's position
contained in Exxon Capital Holdings Corporation (pub. avail. May 13, 1988),
Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991), as interpreted in the
SEC's letter to Shearman & Sterling dated July 2, 1993 and similar no-action
letters (collectively, the "Exxon Capital Letters"); and
· must also be named as a selling noteholder in the prospectus relating to any
resale transaction.
5
Registration Rights Agreement for the Old Notes
When we issued the Old Notes on January 19, 2018, we and the initial purchasers
entered into a registration rights agreement pursuant to which we agreed to use our
commercially reasonable efforts to file a registration statement with respect to an offer
to exchange the Old Notes for substantially identical notes registered under the
Securities Act. This exchange offer is being made pursuant to that registration rights
agreement. We also agreed to use commercially reasonable efforts to cause the
registration statement to be declared effective and to consummate such exchange offer
on or prior to 350 days after January 19, 2018. We also agreed to use our commercially
reasonable efforts to file and cause to become effective a shelf registration statement
relating to the resale of the Notes under certain circumstances. If we fail to satisfy these
obligations, we may be required to pay additional interest on the Notes.

Consequences of Not Exchanging Old Notes
If you do not exchange your Old Notes in the exchange offer, your Old Notes will remain outstanding and continue to accrue interest but will
not retain any rights under the registration rights agreement, except as otherwise specified in that agreement. In addition, you will continue to be
subject to the restrictions on transfer described in the legend on the certificate for your Old Notes. In general, you may offer or sell your Old Notes
only if they are offered or sold:

·
in a transaction registered under the Securities Act and applicable state securities laws;

·
under an exemption from registration under the Securities Act and applicable state securities laws; or

·
in a transaction not subject to the Securities Act and applicable state securities laws.
We do not intend to register the resale of the Old Notes under the Securities Act, and holders of Old Notes that do not exchange Old Notes for
New Notes in the exchange offer will no longer have registration rights with respect to the Old Notes except in the limited circumstances provided
in the registration rights agreement. Under some circumstances, as described in the registration rights agreement, holders of the Old Notes,
including holders who are not permitted to participate in the exchange offer or who may not freely sell New Notes received in the exchange offer,
may require us to file, and to use commercially reasonable efforts to cause to become effective, a shelf registration statement covering resales of the
Old Notes by such holders. For more information regarding the consequences of not tendering your Old Notes, see "The Exchange Offer--
Consequences of Exchanging or Failing to Exchange Old Notes."

Interest Payment Dates
We will pay interest semi-annually in arrears on the New Notes on each February 1
and August 1, with the next interest payment date being February 1, 2019. The initial
interest payment on the New Notes will include all accrued and unpaid interest on the
Old Notes exchanged therefor.
No Guarantees
The Old Notes were initially guaranteed on a senior unsecured basis by certain of our
subsidiaries. These guarantees were automatically released in connection with our
entry into an amended and restated credit agreement (the "Credit Agreement") on
March 27, 2018. None of our subsidiaries are currently required to be a guarantor of
the Notes.
Ranking
The New Notes will be our senior unsecured debt obligations and will be:
· pari passu in right of payment with all of our existing and future unsecured
senior debt, including our 4.97% series A senior notes due 2020, our 4.27%
series B senior notes due 2022 (together, the "Existing Senior Notes"), the Old
Notes and debt under our Credit Agreement;
· senior in right of payment to all of our future subordinated debt;
· effectively subordinated to all of our future secured debt to the extent of the
value of the assets securing such debt; and
· structurally subordinated to all of the existing and future liabilities (including
trade payables) of each of our subsidiaries.
Optional Redemption
We may redeem the Notes at our option, in whole or in part, at any time or from time
to time prior to November 1, 2027 at a redemption price equal to 100% of the principal
amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, on those
Notes to the redemption date, plus the make-whole amount, if any, as described under
"Description of the Notes--Optional Redemption." We may redeem the Notes at our
option, in whole or in part, at any time or from time to time on or after November 1,
2027 at a redemption price equal to 100% of the principal amount of the Notes to be
redeemed, plus accrued and unpaid interest, if any, on those Notes to the redemption
date.
7
Change of Control Offer
If a change of control triggering event occurs, unless we have exercised our option to
redeem the Notes, we will be required, subject to certain exceptions, to make an offer
to each holder of Notes to repurchase all or any part of that holder's Notes for cash
equal to 101% of the principal amount of the Notes to be repurchased, plus accrued
and unpaid interest, if any, on those Notes to the repurchase date. See "Description of
the Notes--Change of Control Offer."
Certain Covenants
The Notes are subject to certain covenants that, among other things, limit our ability to
incur certain liens, engage in sale and lease-back transactions or consolidate, merge or
transfer all or substantially all of our assets. See "Description of the Notes--
Covenants."
No Established Trading Market
The New Notes are a new issue of securities with no established trading market. The
New Notes will not be listed on any securities exchange or quoted on any automated
dealer quotation system. We cannot assure you that an active or liquid trading market
for the New Notes will develop. If an active or liquid trading market for the New
Notes does not develop, the market price and liquidity of the New Notes may be
adversely affected.
Form and Denominations
The New Notes will be issued in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. The Notes will be represented by one or more
global notes registered in the name of a nominee of DTC. Beneficial interests in the
New Notes will be evidenced by, and transfers thereof will be effected only through,
records maintained by participants of DTC.
