Authors' affiliation:  consulting geologist
Age: Late Cretaceous
Formation:  Woodbine Formation
Location:  Double A Wells field, Downdip Tuscaloosa-Woodbine Trend, Polk County, Texas, United States
Well:  W.T. Carter & Bros. No. 7 (Black Stone Energy)
Depth range: 13942-14059 feet
Depositional Setting:  “The trap is a pinchout of fine-grained sandstones across a structural nose and beneath a marine disconformity that separates gulfward-dipping clinoform beds from onlapping marine transgressive deposits.”  Sandstones at Double A Wells Field are within a turbidite fan.
Porosity Preservation:  “Sandstones are unusually porous for their 14,000 ft depth. ... Emplacement of an initial oil charge, beginning at around 8,000 ft and followed by gas as burial temperature increased, may account for porosities of up to 22% and permeabilities of up to 1.3 darcies, and suggests pore cementation may have been 'shut down' by implaced hydrocarbons.”
Production:  gas and condensate
Core measurement conditions:  Porosity determined with Boyle's law method.  Permeability determined using steady-state method with helium at 400 psig net confining stress.  Measurements by Core Petrophysics, Inc.
