A Houston company, Crimson Exploration Inc., has provided an update on its successful operations in east Texas, including Woodbine, Eagle Ford and other programs. This is important information for the growth of the oil and gas industry in Texas, a crucial component to economic growth and energy independence.
Crimson has 18,500 acres in the Woodbine section that cover three areas the company refers to as Force, Iola-Grimes, and Chalktown. In these areas, the company has been developing the Woodbine, and production tests have confirmed the oil potential in all three areas. Crimson has identified 115 potential drilling locations. Assuming the average output is an ultimate recovery of 400,000 BOE (barrell of of oil equivalent) per location, with 90% oil and natural gas liquids, total net potential exceeds 34 million BOE. That is five times the average for Crimson in 2011.In the Force area, in Madison County, 50 wells have completed since January 2009 using modern horizontal drilling and fracture simulation completion techniques. These wells have had initial rates of 600 b/d of oil. The first two producing Crimson wells initially averaged over 900 b/d of oil, and the area is considered substantially derisked. In Crimson’s first horizontal Woodbine well in this area, the well produced 128,000 barrels in its first four months.
Crimson has 5,100 net acres in the Chalktown area in Madison County as well. It is testing the Lewisville sand, a lower Woodbine objective that has produced vertical wells in the area. One of the wells there is producing extraneous water, possibly from a natural fracture. The company is working to shut off the source of the water to better test the oil potential.
In the Iola-Grimes, in Grimes County, the company has 7,650 net acres and is in active development testing a stratigraphically older Woodbine area than in Force.
In Eagle Ford, recent wells drilled in Brazos, Robertson, and Leon Counties could have potential of more than 600 b/d of oil. Crimson could also add as many as 230 locations and 68 million BOE to its output. Using horizontal and multi-stage frac completion technology, similar to that used at Woodbine, has the potential to increase Crimson’s output in Georgetown, Buda and Glen Rose as well. Georgetown and Buda could each add 58 locations and 17 million BOE. Georgetown wells had an initial rate of above 700 b/d of oil. Buda has initial rates of 600 b/d of oil.
Crimson also has two new primary locations that will likely be drilled in 2013 and might include nine to ten wells in the future. The locations are in Zavala County and Liberty County. In Liberty a former well was lost due to mechanical problems and last produced in January. In Zavala, Crimson delayed completion of wells to better understand optimal completion techniques being developed by other operators in the area.
To those of us both in and out of the oil and gas field, the bottom line is increased production and exploration and that the industry is healthy and growing in Texas. If left alone and allowed to develop naturally, there is no reason the industry will not keep growing and adding to the Texas and American economies for the foreseeable future.
