In Part 1 we covered the basic outline for conformance engineering practices with a focus on understanding the problem and how that impacts success rate. In Part 2 our focus was on making a connection between the problem type and the solution options available for dealing with conformance problems.
Part 3 looks at the importance of performance analysis and how to generate the economic benefit for solving conformance or sweep efficiency problems. The economic elements of this review are very basic, but they will help you to generate a more accurate understanding of the true economic benefit.
Job or Treatment Performance Analysis
As discussed in Part 1, we often misunderstand the full or true nature of the conformance problem we are dealing with. This misunderstanding can often be corrected if we take a careful look at the post solution execution information.
In SPE 103044, we discussed how the first two solutions applied in the Permian Basin Anton Irish field which pumped 8,000 bbl of high-molecular-weight crosslinked gel, followed by 2,000 bbl of nitrified cement, only resulted in the maximum net pressure increase during pumping of 150 psi.
