Unconventional Reservoirs Next Frontier: Efficient Production Modeling – Part 2 Available to Purchase

A novel analytical-numerical hybrid model introduced in SPE 191444¹ is used to illustrate through example applications the benefit of having physics-based models that are practical for automation and integration with monitoring and control systems. The solution integrates the reservoir, completion and surface network, resulting in an efficient model that is readily accessible for daily production optimization. It makes a digital twin for every unconventional well affordable by extensive automation and efficient interface enabling management by exception. In this paper, additional example applications complementing those discussed in SPE 191444 are presented. They include optimization of well-hydraulic fractures positioning in multilayer environment and a quantitative discussion of co-linear versus transverse fracture designs and of the benefits of gas lift optimization. The aim is to illustrate the need/utility for a fast, integrated model that can be used to assist in optimizing the completion and that carry over to production enabling daily production optimization that is practical as opposed to solutions that are too onerous to deploy for every well throughout its lifecycle.
