As to contamination of groundwater, the fracking takes place several thousand feet below the groundwater sources, and since there must be an impermeable layer between the gas-bearing formation and the surface--or else the gas would long since have escaped--there is no communication between the fractured formation and the ground water source.
The key to this new discovery to MSEV is that it was made in the fractured formation that has essentially not been tested in the past.
The logs of the intermediate zone confirmed the existence of a gas column 600 m thick in a fractured formation, and the existence of a column with a total thickness of 110 m in low porosity sandstone reservoirs.
Both wells have been drilled through productive sections of the Austin Chalk, and combined daily production is averaging 220 barrels of oil and 3,300 Mcf of gas, along with 1,100 barrels of associated water resulting from drilling fluid lost in the fractured formation during drilling operations.
We knew we were dealing with a highly fractured formation so when production dropped off again, we decided to re-deepen the well in hopes of intersecting a major fracture.
We are pleased with this successful application of horizontal drilling and underbalanced technology in this vertically fractured formation and look forward to developing this new resource for our shareholders.
In addition, permeability levels determined from the analysis (approximately 4 mD) are believed high enough in a fractured formation to support commercial production in the event that it can be established that the reservoir contains hydrocarbons.
When drilling in formations containing boulders, fractured formations or formations that change from hard to soft and back to hard, it's useful to know when inclination of the bit changes," Crumpton said.
