Canadian Discovery Ltd. estimates Lower Shaunavon original-oil-in-place (OOIP) to be approximately 2.7 billion barrels. Recovery factors appear to be low – four wells/section recover about 2% of the OOIP, while increasing to 16 wells/section increases the recovery factor to between 7 and 10%. It appears that oil pools are the result of conventional-style traps and each pool has a downdip water contact. Production decline type curves show a typical well (at an economic cutoff rate of 4 bopd) will produce about 76,000 bbls of oil at Leitchville, 62,600 bbls of oil at Dollard, and 53,000 bbls of oil at Rapdan. At Leitchville, Kent and Smith (2009) divide the Lower Shaunavon into A and B units. Depositional environment for the B unit is interpreted to be one with little bottom current activity and below fair-weather wave base, or behind a protective barrier with widely-dispersed shallow tidal inlets. The A unit comprises ooids and peloids in a variety of textural compositions, from lime mudstones through wackestones, wacke-packstones, packstones and grainstones, and was deposited above wave base in an environment where wind and waves could create shoals. Most Lower Shaunavon production occurs above the zero contour on the Lower Shaunavon Third-Order Residual Structure.
