【 摘 要 】

Progress is reported for the period from October 1, 2001 to December 31, 2001. Technical design and budget for a larger (60-acre) CO{sub 2} demonstration project are being reviewed by the US DOE for approval. While this review process is being conducted, work is proceeding on well testing to obtain reservoir properties and on the VIP reservoir simulation model to improve model prediction and better understand the controls that certain parameters exert on predicted performance. Testing of present Colliver lease injection water on Lansing-Kansas City (L-KC) oomoldic rock indicates that injection brine must be filtered to < {approx}3-5 um and <15 um to prevent plugging of rocks with permeability as low as 1 md (millidarcy; 0.001 um2) and 10 md (0.01 um2), respectively. Pressure build-up testing on the Carter-Colliver No.7 well is interpreted to indicate the L-KC reservoir surrounding this well is {approx}9 ft (2.7 m) thick having an average effective water permeability of 25-35 md (0.025-0.035 um2) that is connected to the wellbore by either a high permeability fracture, bed, or region with low skin. Reservoir simulation evaluation of gridcell size effect on model oil recovery prediction indicates that, based on the model prediction of distribution of produced oil and CO{sub 2} volumes, oil recovery is strongly influenced by gravity segregation of CO{sub 2} into the upper higher permeability layers and indicates the strong control that vertical permeability and permeability barriers between depositional flood cycles exert on the CO{sub 2} flooding process. Simulations were performed on modifications of the 60-acre, two-injector pattern to evaluate oil recovery using other large-scale patterns. Simulations indicated that several 73-acre patterns with a single injector located near the Colliver No.7 could provide improved economics without increasing the amount of CO{sub 2} injected. The US Energy Partners ethanol plant in Russell, KS began operations in October ahead of schedule.
