Prudhoe Bay field, entering its third decade of production, has produced over 9 BBO. Increasingly smaller reserve targets have been made economically and operationally viable with sustained reductions in drilling costs, significant improvements in geosteering drilling capabilities, and well targeting resolution on the order of tens of feet. This diminishing, complex, and tightly constrained production environment mandates continual efforts to reduce technical risk and improve operating efficiency. The Previous HitanalysisNext Hit of development Previous HitplayNext Hit types is one such effort.

Complex oil fields such as Prudhoe Bay field can be meaningfully subdivided into development Previous HitplayNext Hit types which represent significant categories of reserve opportunities that share similar combinations of geologic, drilling, and/or engineering risk, as well as performance. A statistical basis for the prediction of Previous HitplayNext Hit type performance, risk reduction, and reserve potential can be attained by reviewing the performance of many wells that represent a given Previous HitplayNext Hit type. These performance appraisals can provide metrics and insight to systematically improve performance by focusing on improved drilling and targeting practices, as well as focusing our data gathering and Previous HitanalysisNext Hit on critical Previous HitplayNext Hit risks only. Previous HitPlayNext Hit type Previous HitanalysisNext Hit provides the basis for portfolio management, as opposed to individual well prediction and management. Furthermore, identification of key Previous HitplayTop risks versus reserves potential can dramatically focus technology development efforts.
