... problems and to determine optimum length of the stinger. This laboratory investigation used a large Hele-Shaw cell with water and refined oil as the fluids. The experiment was run for various oil viscosity, oil column thickness, stinger lengths, and production rates to study water cone development under...

... the oil bank would limit the efficacy of the tertiary process' unless an appropriate balance was made of oil production from the oil column and simultaneous water production from the underlying aquifer. Further, it was found that without water injection into the aquifer subsequent to the oil bank reaching...

... and natural water influx with excellent gravity segregation from which an estimated 452,226,000 barrels of oil or 68.8 percent of the original oil-in-place will be recovered. Since simultaneous production of the gas cap during the life of the oil column could be detrimental to oil recovery, gas cap...
