<P align="center" style="font-size: 12pt"><FONT style="font-size: 14pt"><B>Patterson-UTI Energy Reports Financial Results for Three and Twelve Months Ended December&nbsp;31,<BR>
2013</B></FONT><BR>
<FONT style="font-size: 12pt"><B>Doubles Quarterly Dividend</B></FONT>



<P align="left" style="font-size: 12pt"><B>HOUSTON, Texas &#150; February&nbsp;6, 2014 &#150; PATTERSON-UTI ENERGY, INC. (NASDAQ: PTEN) </B>today reported
financial results for the three and twelve months ended December&nbsp;31, 2013. The Company reported
net income of $16.6&nbsp;million, or $0.11 per share, for the fourth quarter of 2013, compared to net
income of $58.9&nbsp;million, or $0.40 per share, for the quarter ended December&nbsp;31, 2012. Revenues for
the fourth quarter of 2013 were $659&nbsp;million, compared to $653&nbsp;million for the fourth quarter of
2012.


<P align="left" style="font-size: 12pt">The financial results for the three months ended December&nbsp;31, 2013 included a pretax non-cash
charge of $37.8&nbsp;million ($24.1&nbsp;million after-tax or $0.17 per share) related to the Company&#146;s
mechanically powered rig fleet. This non-cash charge included the retirement of 48 mechanical
drilling rigs.


<P align="left" style="font-size: 12pt">The Company reported net income of $188&nbsp;million, or $1.28 per share, for the year ended December
31, 2013, compared to net income of $299&nbsp;million, or $1.96 per share, for the year ended December
31, 2012. Revenues for the year ended December&nbsp;31, 2013 were $2.7&nbsp;billion, compared to $2.7
billion for 2012.


<P align="left" style="font-size: 12pt">The Company declared a quarterly cash dividend on its common stock of $0.10 per share, to be paid
on March&nbsp;27, 2014 to holders of record as of March&nbsp;12, 2014. This dividend represents a doubling
of the Company&#146;s recent quarterly cash dividends.


<P align="left" style="font-size: 12pt">Andy Hendricks, Patterson-UTI&#146;s Chief Executive Officer, stated, &#147;We are pleased with our rig count
growth in the latter part of the fourth quarter, as our average rig count in the United States
increased to 187 rigs in December from 178 in October. Demand is strong for high-specification
APEX<sup>&#174;</sup> rigs, and utilization remains high. Additionally, demand has improved for our
fleet of non-APEX electric rigs. In total, during the fourth quarter, our average operating rig
count in the United States increased to 183 rigs from 181 in the third quarter and our average
operating rig count in Canada increased to nine from eight in the third quarter.&#148;


<P align="left" style="font-size: 12pt">Mr.&nbsp;Hendricks added, &#147;During the fourth quarter, we recognized $2.4&nbsp;million of revenues related to
early contract terminations, which positively impacted our average rig revenue per day of $23,300
by approximately $130. Excluding the impact of early termination revenue in both the third and
fourth quarters, average rig revenue per day increased $520 to $23,170 in the fourth quarter from
$22,650 in the third quarter.


<P align="left" style="font-size: 12pt">&#147;In addition to the increase in average revenue per day, average rig operating costs per day
decreased $240 sequentially to $13,510 in the fourth quarter from $13,750 in the third quarter.
Accordingly, excluding the positive impact from the early termination revenues in both the third
and fourth quarters, average rig margin per day increased $760 to $9,660 in the fourth quarter from
$8,900 in the third quarter.


<P align="left" style="font-size: 12pt">&#147;We completed three new APEX<sup>&#174;</sup> rigs during the fourth quarter for a total of 11 new
APEX<sup>&#174;</sup> rigs during 2013. We plan to complete 20 new APEX<sup>&#174;</sup> rigs during 2014,
including three in the first quarter. Since our last earnings release, we have contracted seven
new APEX<sup>&#174;</sup> rigs, resulting in 10 of our planned new APEX<sup>&#174;</sup> rigs for 2014 being
under contract.


<P align="left" style="font-size: 12pt">&#147;As of December&nbsp;31, 2013, we had term contracts for drilling rigs providing for approximately $946
million of future dayrate drilling revenue. Based on contracts currently in place, we expect an
average of 124 rigs operating under term contracts during the first quarter, and an average of 93
rigs operating under term contracts during 2014.


<P align="left" style="font-size: 12pt">&#147;As expected, in pressure pumping, the seasonal decline in activity during the fourth quarter
resulted in a sequential decrease in revenues. Despite this decrease, our gross margin modestly
improved to 21.5% of revenues. Pressure pumping EBITDA during the fourth quarter was $45.8
million,&#148; he concluded.


<P align="left" style="font-size: 12pt">Mark S. Siegel, Chairman of Patterson-UTI, stated, &#147;During 2013 we grew our fleet of
high-specification APEX<sup>&#174;</sup> rigs to 124, and for the year we achieved better than 95%
utilization of these rigs. As customer demand increased during the fourth quarter, we were quickly
able to respond by reactivating non-APEX electric rigs to satisfy this need. Our fleet of
high-specification APEX<sup>&#174;</sup> rigs and other electric drilling rigs now represents almost
two-thirds of our total rig fleet, and accounted for approximately 87% of contract drilling EBITDA
during 2013.


<P align="left" style="font-size: 12pt">&#147;The increasing demand for high-specification rigs to drill complex, horizontal wells continues.
More recently the focus on horizontal wells in the Permian Basin has accelerated, and we are well
positioned as a market leader in this region and in walking rig technology for pad drilling.


<P align="left" style="font-size: 12pt">&#147;Although pressure pumping remains competitive, the increase in complex, horizontal wells should
positively impact activity in 2014. Our focus on well-site execution and customer relationships
has generated competitive advantages for us, and allowed us to activate equipment at the beginning
of 2013 and keep our equipment active during the year.&#148;


<P align="left" style="font-size: 12pt">Mr.&nbsp;Siegel added, &#147;Our Board doubled the quarterly cash dividend in recognition that the Company&#146;s
transformation has had a profound impact on our financial results. We embark on this higher payout
to our shareholders based on our belief that we are now &#150; as a result of a multi-year investment
program &#150; a far stronger company with significantly improved businesses and prospects. In
addition, during 2013 we repurchased approximately $85.8&nbsp;million of stock at an average price of
$20.83 per share, and we have approximately $187&nbsp;million remaining under our stock buyback
program,&#148; he concluded.


<P align="left" style="font-size: 12pt">The financial results for the year ended December&nbsp;31, 2013 include the aforementioned pretax charge
of $37.8&nbsp;million ($24.1&nbsp;million after-tax) related to the Company&#146;s mechanically powered rig fleet,
$62.8&nbsp;million of revenues from the early termination of six rigs in the third quarter, and $1.7
million of selling, general and administrative expenses related to the evaluation of and
preparation for international opportunities. Included in the financial results for the year ended
