CONTRACT DRILLING SEGMENT INFORMATION

The average number of drilling rigs used in the first quarter of 2011
was 70.0, an increase of 38% over the first quarter of 2010, and a
decrease of 1% from the fourth quarter of 2010. Per day drilling rig
rates for the first quarter of 2011 averaged $17,704, up 25% (or $3,577)
from the first quarter of 2010, and up 7% (or $1,134) from the fourth
quarter of 2010. Average per day operating margin for the first quarter
of 2011 was $8,077 (before elimination of intercompany drilling rig
profit of $5.0 million). This compares to $4,435 (before elimination of
intercompany drilling rig profit of $0.4 million) for the first quarter
of 2010, an increase of 82%, or $3,642. As compared to the fourth
quarter of 2010 ($7,559 before elimination of intercompany drilling rig
profit of $4.4 million) first quarter 2011 operating margin increased 7%
or $518 – in each case with regard to the elimination of intercompany
drilling rig profit see Non-GAAP Financial Measures below.

Larry Pinkston, Unit’s Chief Executive Officer and President, said: “We
are pleased with the results from our contract drilling segment. Our
utilization rates have remained strong and we have obtained an increase
in drilling rig day rates over the fourth quarter of 2010. Our fleet
went through a transition in 2010 to accommodate the growing industry
focus on drilling horizontal or directional wells. We refurbished and
upgraded 30 drilling rigs in 2010 in order that they could undertake
this type of drilling. Approximately 80% of our drilling rigs working
today are drilling for oil or natural gas liquids and approximately 99%
are drilling horizontal or directional wells. We had previously
announced that during 2011 we will add five new drilling rigs to our
fleet, all of which are 1,500 horsepower, diesel-electric drilling rigs
under two-year term contracts. To date, two of those five drilling rigs
have begun operating bringing our current total fleet to 123 drilling
rigs. Currently, 76 of our 123 drilling rigs are under contract. Term
contracts (contracts with original terms ranging from six months to two
years in length) are in place for 41 of the 76 contracted drilling rigs.
Of these contracts 13 are up for renewal during the second quarter of
2011, nine during the third quarter of 2011, ten during the fourth
quarter of 2011, and nine after 2011. These contracts do not include the
term contracts for the three remaining new drilling rigs to be added to
our fleet later this year.”

In the Marmaton horizontal oil play located in Beaver County, Oklahoma,
Unit had first sales on nine wells during the first quarter, in which it
has an average working interest of approximately 91%. The 30-day average
production rate for the nine wells was 238 Boe per day. The average
ultimate recovery for a Marmaton well is estimated at 130 MBoe comprised
of 76% oil, 14% NGLs, and 10% natural gas, with an average cost per well
of $2.8 million. Unit has scheduled three to four frac dates per month
for 2011 which should cover its current two rig drilling program. For
2011, Unit anticipates having first oil sales on 30 to 36 gross wells
within this play at a total net cost of $52 million. Unit currently has
leases on approximately 66,000 net acres in the play.

In the Granite Wash (GW) play located in the Texas Panhandle, Unit had
first sales on five horizontal wells during the first quarter. Unit’s
average working interest in these wells is 76%. Of the five new wells,
one well was completed in the GW “A”, two in the GW “B”, one in the GW
“D” and one in the GW “F” zone. The average 30 day rate of production
for these five wells was 6.0 MMcfe per day, consisting of 16% oil, 33%
NGLs and 51% natural gas. Highlighting the first quarter wells was the
first horizontal GW “D” zone completion. That completion resulted in a
peak daily rate of 483 barrels of oil per day, 474 barrels of NGLs and
4.4 MMcf of natural gas or an equivalent rate of 10.1 MMcfe per day. The
30 day average production rate for this well was 7.0 MMcfe per day.
Anticipated reserves for the GW formation production from the five
horizontal wells is 4.0 Bcfe per well, comprised of 10% oil, 37% NGLs
and 53% natural gas at a total net cost of $5.2 million. In addition,
Unit participated in three outside operated GW horizontal wells, with an
average working interest of 11%. Unit plans to work three to four Unit
drilling rigs drilling Granite Wash horizontal wells in 2011 which
should result in 20 to 22 operated GW wells drilled during the year with
a projected total net cost of $82 million.

Pinkston said: “We are pleased with the results of our drilling activity
for the quarter. The first quarter of 2011 is the third consecutive
quarter that production has increased. Our strategy of focusing on oil
or NGLs rich prospects is evident in our first quarter 2011 production
results of which 38% was oil and NGLs as compared to 29% in the first
quarter of 2010 and 34% in the fourth quarter of 2010. For the quarter,
we completed 34 gross wells with a success rate of 91% compared to 27
gross wells with a 96% success rate during the first quarter of 2010.
For the year, we plan to drill 180 gross wells with an anticipated
annual production guidance of approximately 11.0 to 11.3 MMBoe, an
increase of 11% to 15% over 2010.”

MID-STREAM SEGMENT INFORMATION

  • Increased first quarter 2011 liquids sold per day volumes, processing
    volumes per day, and gathering volumes per day by 29%, 13% and 3%,
    respectively, over the first quarter of 2010.
  • Construction of 16-mile pipeline and related compressor station in
    Preston County, West Virginia is on schedule to be operational by
    mid-2011.
  • Signed contract to build a 12-mile pipeline system and compressor
    station in Tioga and Potter Counties, Pennsylvania.

First quarter of 2011 per day processing volumes were 86,445 MMBtu while
liquids sold volumes were 328,333 gallons per day, an increase of 13%
and 29%, respectively, over first quarter of 2010. First quarter 2011
per day gathering volumes were 185,730 MMBtu, up 3% over the first
quarter of 2010. Operating profit (as defined in the Selected Financial
and Operational Highlights) for the first quarter was $10.7 million, an
increase of 27% from the first quarter of 2010, primarily due to
increased processing margins resulting from increased liquids prices and
increased volumes.

Pinkston said: “Processing and liquids sold volumes continue to increase
and gas gathered volumes remain strong. As previously announced, we
completed the installation and startup of a 50.0 MMcf per day
turbo-expander natural gas processing plant at our Hemphill facility
near Canadian, Texas, during the fourth quarter of 2010. With the
completion of this new plant, the total processing capacity at our
Hemphill facility has increased to approximately 100.0 MMcf per day. In
connection with our Appalachian operations, we recently started
construction of a 16-mile, 16″ pipeline and a compressor
station in Preston County, West Virginia, which will have a capacity of
approximately 220.0 MMcf per day. We anticipate this pipeline will
be operational by mid-2011. In addition to the Preston County pipeline,
we recently signed a contract to build a 12-mile pipeline system and
compressor station in Tioga and Potter Counties, Pennsylvania. This
system will deliver gas to Dominion Transmission pipeline and is
scheduled to be completed in the fourth quarter of this year.”

FINANCIAL INFORMATION

Unit ended the first quarter of 2011 with working capital of $12.7
million, long-term debt of $185.0 million, and a debt to capitalization
ratio of 10%. Under its credit facility, the amount available to be

million.

MANAGEMENT COMMENT

Larry Pinkston said: “Our first quarter 2011 operating results were
solid. We continue to focus our exploration efforts on our oil and
natural gas liquids rich plays such as the Granite Wash and Marmaton. On
the drilling side, we plan to continue responding to the demand for
horizontal drilling by our customers by refurbishing and upgrading our
existing rigs and, where appropriate, adding new drilling rigs to our
fleet. Our mid-stream segment is also exploring for additional
opportunities to grow its operations. We are optimistic about 2011, and
our balance sheet is well positioned to take advantage of growth
opportunities that may arise in all three of our business segments
during the year.”
