one of the world's greatest inventions- the rotary table *- Petro-Hunt Presents Case for New Field and 1,280 Acre Well Density for Delaware Basin ShalesThe Texas Railroad Commission held a hearing on Wednesday, August 23rd, to consider the uncontested application of Petro-Hunt LLC to establish a new field to be known as the Toyah, NW (Shale) Field for the Woodford and Barnett Shale Formations in Reeves County Texas. At the hearing Petro-Hunt also sought density rules allowing vertical wells to hold 1,280 acres and horizontal wells to hold acreage amounts that would be more than 1,280 acres and be based on the length of the drainholes. The unit size requested by Petro-Hunt is double the size of the largest units (640 acres) that are typically requested in Texas field rule applications and are quadruple the size of the largest allowed acreage unit in the Newark East (Barnett Shale) Field in north Texas (320 acres). There is, however, miles of undeveloped land to be held in the area and, driving the segment of I-10 between Fort Stockton and El Paso you understand why the Wall Street Journal called the potential gas play "The Big Empty". The combined population of Reeves, Pecos and Culberson Counties is 30,124 while the combined area of those counties is 11,213 square miles. At the roughly hour-long hearing Petro-Hunt presented in very general terms the status of the Barnett Shale/Woodford play in west Texas. Petro-Hunt’s witness testified that of the 15 to 20 wells drilled and tested in the area, none have shown commercial levels of gas production. There is one well, the discovery well, in the proposed Toyah, NW (Shale) Field, the Block 59 State 35 #1H (API No. 42-389-32371). The Block 59 State 35 #1H is located in Section 35, Block 59, PSL Survey, Abstract 2670, Reeves County, approximately 9.8 miles northwest of Toyah, Texas. The well was completed on April 29, 2006 with an initial potential of 213 mcf of gas per day. The well has a horizontal lateral of approximately 3,100 feet in length in the Barnett Shale between the depths of 13,146’ to 13,953’ measured depth. Because of difficulties encountered while drilling the well, costs to drill just the vertical section escalated to $15 million. The well was sidetracked multiple times and, due to additional downhole problems, Petro-Hunt could not drill the lateral to its desired length of 4,000 feet. As of mid August the Block 59 State 35 #1H was producing at a flat gas rate of 300 mcf of gas per day with 50 barrels of water per day. Petro-Hunt believes that factors behind its marginal test in the discovery well include: 1) bad frac: Petro-Hunt believes that gas is coming from only the first stage, closest to the heel of the well, of the three stage frac. The frac. was modeled after the fracs being done in the Fort Worth Barnett Shale. (Petro-Hunt believes that a different type of frac. will have to be designed.) 2) insufficient lateral: The lateral in the discovery well was approximately 3,100 feet long. Petro-Hunt believes that future wells will need to be drilled with laterals 4,000 to 5,000 feet long and multiple laterals will have to be drilled. (Opposing and stacked laterals are being contemplated.) 3) the lateral’s orientation was not ideal: Petro-Hunt relied upon 2D seismic data in drilling its lateral. The lateral was drilled in a north-south location. A southwest-northeast trending fault located 2,000’ to the southeast of the well’s surface location has been identified. Mr. Roberts stated that the results from the well might have been different had the lateral been drilled perpendicular to the maximum stress direction, parallel to the fault.

Extension of Edwards Trend in Live Oak County On February 23rd The Exploration Company out of San Antonio received permits from the Railroad Commission to inject steam into the Upper Cretaceous San Miguel Formation through two wells on its 158,270 acre Chittim ‘B’ Lease in Maverick County. The steam injection will aid in unlocking "one of the most dense, viscous, and sulphur-laden hydrocarbon deposits in the world", according to an article in the December 19, 2005 issue of the Oil & Gas Journal. According to Calgary based Newmex Minerals, which is also involved in the project with The Exploration Company, the tar saturations range from 20 percent to 60 percent. The San Miguel is a sandstone formation with an average pay thickness of 40 feet. Filings with the Railroad Commission show that The Exploration Company plans to inject an average of 1,350 barrels of fresh water steam per day through each well, the Chittim "B" #2374 and Chittim "B" # 1374, in ten day increments, and expects to recover 1 barrel of oil from the formation for every 10 barrels of fresh water steam injected. The limited project area at this point is 640 acres of Section 374, C.H. Dillingham Survey (A-92) and 640 acres of Section 373, G.W. Bowman Survey (A-42) for a total number of 1280 acres. The Exploration Company will extract fresh water from the Carrizo Formation, which is found at a depth of 150 feet. The volume of recoverable fresh water that The Exploration Co. has rights to under the pilot area is 83,414,000 barrels.

The application (Oil & Gas Docket 09-0247286) was brought to the Commission by Infinity Oil Gas of Texas. This new tight gas area for the Barnett Shale allows current and future gas wells in Erath County producing from the Barnett to qualify for high cost gas certifications. At the time the application was prepared, eight wells in Erath County were completed in the Barnett Shale Formation. Railroad Commission records show that 139 drilling permits for completion in the Barnett Shale have been filed as of Friday, almost all of them since 2005. Johnston & Cloud, an Austin based regulatory consulting and engineering firm that prepared the study and application on behalf of Infinity, provided in-situ permeability and pre-stimulation stabilized AOF calculations for only one data point well. The calculations from the data point well met the specifications for the formation to be classified as a tight gas formation - that in-situ permeability could not exceed 0.1 millidarcies, that the pre-stimulation AOF could not exceed 122 mscf/day, and that the pre-stimulation rate of any oil production was not greater than 5 barrels per day.

Production In March 2009, operators reported 683 oil, 1,176 gas, 203 injection and six other completions compared to 456 oil, 800 gas, 42 injection and zero other completions during March 2008. Total well completions for 2009 year to date are 5,252 up from 4,018 recorded during the same period in 2008. Operators reported 395 holes plugged and one dry hole in March 2009 compared to 580 holes plugged and three dry holes in March 2008. *- February Natural Gas Production Texas oil and gas wells produced 510,536,175 Mcf (thousand cubic feet) of gas based upon preliminary production figures for February 2009, up from the February 2008 preliminary gas production total of 479,246,697 Mcf. Texas production in February 2009 came from 140,646 oil and 87,160 gas wells.
