Petrohawk: A Very Successful Producer In Shale Gas Plays

Consider the following facts and figures. The numbers of wells drilled, their success rate, and production rates all demonstrate a very skilled operation. The follwing comes from Petrohawk's own website here.

Petrohawk Provides Fourth Quarter Operational Update (2008)

Final Proved Reserves up 34% Year Over Year at 1.42 Tcfe, 419% of Production Replaced Haynesville Shale Gross Operated Production Reaches 160 Mmcfe/d

HOUSTON, Feb. 3 /PRNewswire-FirstCall/ -- Petrohawk Energy Corporation ("Petrohawk" or the "Company") (NYSE: HK) provided its fourth quarter 2008 operational update, including additional drilling results in the Haynesville Shale and proved reserves for year-end 2008.
During the fourth quarter, Petrohawk drilled 218 wells, with a success rate of 98%. On average, 32 operated rigs and 15 non-operated rigs were running during the quarter, including a combination of spudder rigs and horizontal rigs in both the Haynesville Shale and Fayetteville Shale development programs. For 2008, Petrohawk drilled 739 total wells, also with a success rate of 98%.

Production for the fourth quarter was approximately 361 million cubic feet of natural gas equivalent (Mmcfe/d), a 15% quarter over quarter increase and a 52% increase over fourth quarter 2007, on a pro forma basis. Petrohawk exited the quarter producing approximately 400 Mmcfe/d. Full year 2008 production was approximately 305 Mmcfe/d.

Petrohawk recently placed four additional wells online utilizing production practices consistent with previously reported wells. The initial production rates of these wells averaged 17.7 Mmcfe/d, detailed as follows:

The Mack Hogan #4 (Bossier Parish, Section 3, 16N, 11W) had an initial production rate of 13.4 Mmcfe/d on a 24/64" choke with 6,350# flowing casing pressure.

The Osborne 8 #3H (Bossier Parish, Section 8, 16N, 11W) had an initial production rate of 18.8 Mmcfe/d on a 24/64" choke with 6,800# flowing casing pressure.

The Roos "A" #5 (Bossier Parish, Section 3, 16N, 11W) had an initial production rate of 15.1 Mmcfe/d on a 24/64" choke with 6,100# flowing casing pressure.

The Griffith 11 #1 (DeSoto Parish, Section 11, 13N, 14W) had an initial production rate of 23.3 Mmcfe/d on a 28/64" choke with 7,550# flowing casing pressure. This well is a significant step-out to the southwest from existing completions.

Two Haynesville Shale completions, the Sample 4 #1 and the R.E. Smith Jr. 32 #1, experienced mechanical problems that resulted in lower than expected initial production rates. On the Sample 4 #1, a valve malfunctioned following completion, causing casing damage in the lateral portion of the well. The Company elected to produce the well on a 12/64" choke as a precaution against further wellbore damage. This well had an initial production rate of 5.4 Mmcfe/d with 7,020# flowing casing pressure. The R.E. Smith Jr. 32 #1 screened out halfway through completion due to the inadvertent firing of a perforating gun in the curve of the lateral. With only six stages of fracture stimulation, this well had an initial production rate of 11.1 Mmcfe/d on a 20/64" choke with 5,900# flowing casing pressure.

The Company is currently producing approximately 160 Mmcfe/d gross from the Haynesville Shale with 16 operated wells on production. Eleven operated wells have been on production 30 days or more, averaging 15.2 Mmcfe/d over their first 30 days of production. Eight operated wells have been on production 60 days or more, averaging 13.2 Mmcfe/d over their first 60 days of production. The four wells on production greater than 90 days have averaged 8.8 Mmcfe/d over their first 90 days of production. All operated wells to date have been produced utilizing similar production practices. During 2009, Petrohawk will conduct a pilot program on certain wells whereby production practices will be altered to restrict production by utilizing smaller choke sizes. The Company will monitor this subset of wells for effects on decline rate and mechanical operation.

Petrohawk's current drilling and completion methodology focuses on completing wells with longer laterals and maximizing the number of frac stages, spaced approximately 325 feet apart. The objective of this technique is to minimize the total number of wells required to effectively drain the reservoir, resulting in lower overall development costs. The Company is currently targeting lateral lengths between 4,300' and 4,600' with up to 15 frac stages. Petrohawk's first four completions averaged 3,339' in lateral length with 10 frac stages while the last twelve completions have averaged 3,958' in lateral length and 12 stages (with the exception of the R.E. Smith Jr 32 #3, which had down hole mechanical issues and only six frac stages).

During 2008, the Company utilized a "pre-drill" program whereby smaller, "spudder" rigs drilled the vertical portion of the wellbore in advance of horizontal rigs moving in to drill the lateral. At year end 2008, Petrohawk had eleven operated horizontal rigs running in the Haynesville Shale. The Company expects spud-to-first sales to average approximately 75 days during 2009, assuming longer laterals are drilled.

Petrohawk has budgeted $690 million for Haynesville Shale drilling in 2009. Seventy-five to eighty gross operated wells are budgeted, with approximately 6 wells expected to be completed per month. The Company expects to operate an average of 12 rigs in the play in 2009 with an emphasis on holding operated acreage.

Eagle Ford Shale
A second well in Petrohawk's Eagle Ford Shale discovery in South Texas, formally known as Hawkville Field, was completed in mid-January. The Dora Martin #1H, located approximately 14 miles west of the Company's first Eagle Ford Shale well, tested at a rate of 8.3 Mmcfe/d on a 22/64" choke with 4,610# flowing casing pressure. The well was drilled to a true vertical depth of approximately 11,000' and had a lateral length of 4,300' with 12 stages of fracture stimulation. The Company has also reached total depth on its third well, the Donnell #1H. Completion is scheduled for mid-February. Petrohawk is currently running one rig in the play with drilling and completion expected to average 50 days.

Fayetteville Shale
During the fourth quarter, Petrohawk drilled 44 operated and 74 non-operated wells in the Fayetteville Shale. Of 143 horizontal wells drilled during 2008, 113 had state test data available at December 31, 12 were waiting on state tests to be performed, and 18 were waiting on completion due to the delayed in-operation date of the Boardwalk pipeline. Current gross operated production in the Fayetteville Shale reached approximately 145 Mmcfe/d as of December 31, 2008.

Throughout 2008, the Company experienced significant operational improvements in the results of its completions, primarily as a result of drilling longer laterals with cemented liners. This supported by the following data comparing first quarter 2008 and fourth quarter 2008 techniques and results as follows:
Percentage of cemented liners increased from 4% in the first quarter to 100% in the fourth quarter.
Average lateral length increased from 2,286' in the first quarter to 2,655' in the fourth quarter, a 16% increase.
Average number of frac stages increased from 6.0 in the first quarter to 7.6 in the fourth quarter, a 27% increase.
Average state initial production test rate increased from 1.919 Mmcfe/d in the first quarter to 2.456 in Mmcfe/d in the fourth quarter, a 28% increase.
Percentage of completions that tested greater than 3 Mmcfe/d increased from 12% in the first quarter to 54% in the fourth quarter, with 2 wells in the second half of 2008 testing greater than 5 Mmcfe/d.

Price realizations and overall production from the Fayetteville Shale were impacted in the fourth quarter by a delay in the completion of a new third-party pipeline, which increased demand on other transportation lines servicing the play, causing wider than normal basis differentials. Production was either sold at lower than normal prices or shut in at various times during the quarter as a result of these market conditions. The new pipeline, constructed by Boardwalk Pipeline Partners LP, is currently in service and the Company currently expects no additional transportation constraints on its production in the area.

New Gathering Subsidiary - Hawk Field Services, LLC
During 2008, Petrohawk initiated construction of its own gathering systems servicing the Company's as well as third party production in the Fayetteville Shale and Haynesville Shale. Operating under a new subsidiary, Hawk Field Services, LLC, Petrohawk constructed approximately 100 miles of gathering lines in the Fayetteville Shale in 2008, with approximately 150 miles of gathering lines currently in service, under construction or planned in the Haynesville Shale during 2009.
