Optimizing a well requires an understanding of all the parameters that govern the existing production rate, as well as an understanding of the production potential. The challenge in unconventional reservoirs is that the reservoir deliverability governing the existing rate changes with time. Hess's unconventional acreage in the Bakken field (tight oil, in this instance) spreads across North Dakota, with over 1,000 wells on artificial lift. The addition of an artificial lift system adds to the complexity of understanding a well's performance. The objective for well optimization in this paper is to understand current well performance and quantify potential production gains from changing operating parameters. This paper proposes a new approach to modeling and optimizing the well performance of an unconventional well that captures the flow hydraulics from the sandface to the sales point using an Integrated Production Model from the Petroleum Experts suite of software.
