Best Practices in Khurais Complex Development

Abstract

AbstractThis article discusses the upstream development of Khurais field, referred to here interchangeably as the Khurais complex, consisting of several fields and reservoirs with a capacity of 1.2 million barrels per day (MMBPD) of Arabian Light crude. It describes the planning, execution and leveraging of technologies coupled with best industry practices to deliver the target rate while reducing the unit development cost, increasing the well productivities and expanding the reserves base. At the beginning of the project, a high resolution 3D seismic program was successfully performed to characterize the reservoir structure and geological features. Coupled with vertical-horizontal delineation wells, additional reserves were delineated and added to the development. To reduce the unit development cost, this article will show that the project utilizes a complex well architecture with a combination of maximum reservoir contact (MRC), multilateral, and horizontal wells, as well as smart completion (SC), smart electrical submersible pump (ESP), and passive inflow control devices to achieve and sustain the target rates. The development also sets the stage for technology leveraging in the future by drilling wells with large wellbores, allowing flexibility for the next-generation of complex well architecture while pursuing fit-for-purpose technologies through joint ventures and Saudi Aramco's Exploration and Petroleum Engineering Center -Advanced Research Center (EXPEC ARC).

Green Enhanced Oil Recovery for Carbonate Reservoirs

“…Not a lot of other data for the Khurais field is present. Still, as it has both Arab-D and Hanifa formations, its properties would be similar to the Abqaiq field mentioned earlier in the report [40][41][42][43][44][45].…”
