PRESS RELEASE
PetroMax Operating using the newest drilling and completion techniques in the industry on horizontal Woodbine wells in Brazos and Madison Co, Texas.
East Texas Woodbine Formation October 29, 2009 Drilling & Completion – Garland, Texas-based PetroMax Operating Co. Inc. has announced that completion techniques have advanced and improved again to increase oil production from the new horizontal wells they are drilling in the Kurten field. The first four (4) horizontal wells drilled by PetroMax were completed with a completion method known as multi stage fracing. Isolated frac stages are created with the use of swellable external casing packers and ball-actuated stimulation sleeves. PetroMax is now moving to a more fail safe completion strategy of using pump down plugs in place of the ball actuated sleeves. The drilled horizontal wells allow maximum exposure to a reservoir, and the new pump down plug completion technique allows fracturing of the Woodbine formation along the full extent of the wellbore to maximize production.
How It Works………. First a combination bridge and perforating gun attached to a wire line are pumped into the horizontal well bore to an exact location. The plug is set and the perforating gun is freed to be pulled back to the desired location. The gun is fired, pulled from the well and the frac is initiated from the surface. Upon frac completion another combination bridge and perforating gun is pumped into the well bore and set up hole from the previously treated zone to isolate it while the next zone is perforated and treated.
The procedure is repeated until all stages have been treated. The composite bridge plugs are drilled up and the well is cleaned and made ready for final production. Some of the benefits of this new completion technique are: unlimited potential frac stages, reduced statistical/mechanical failures associated with the ball activated sleeves, and continued mechanical engineering of the wells that will lead to increased production at lower cost per barrel.
PetroMax will utilize the new pump down plug completion technique on the Wilson #1H which has a fifteen stage frac procedure scheduled for completion.
