... these trials. The extended chemical injection field trial was executed in ~ 40 acre, horizontal line drive pattern utilizing two horizontal injectors and four horizontal producers with two vertical pressure observation wells. The evaluation of injection results was based on actual daily production...

... recovery at 14.7 psi (atm pressure) of two times that of reservoir water only, while the laboratory result with coreflood shows additional recovery after chemical injection of 30% to 50% beyond primary and water injection stage. The implementation is technically simple and it is able to be conducted...
