Experimental Design Reduces Risks of a Siberian Development Having Subsurface and Financial Uncertainties

摘要

Experimental-design methodologies were used to evaluate development options in a Siberian field having major uncertainties in geological, reservoir, and financial parameters. The approach demonstrated that an inverted seven-spot injection pattern would yield 11% more oil than a conventional linedrive method. For decision making, the analysis predicted that the expected net present value (NPV) of the seven-spot pattern would be 46% more than that of the linedrive pattern.
