“…In addition, it is observed that installing ICDs do not guarantee a uniform flow in horizontal wells. A well-designed ICD completion, assisted by wellbore hydraulic modeling, however, can promote production from the entire horizontal lateral and mitigate the effect of the severe pressure gradients, eliminating cross-flows (Krinis et al 2009). …”

Flow profiles of horizontal wells in heterogeneous or fractured reservoirs are usually nonuniform and are frequently characterized by high flow capacity from streaks in high permeable zones or fractures. The nonuniform flow usually causes early water breakthrough that ultimately undermines well productivity. In homogeneous reservoirs, water (or gas) breakthrough commonly occurs at the heel of the lateral section. In either case, whether in homogeneous or heterogeneous reservoirs, achieving uniform flow along the wellbore in horizontal wells to improve sweep efficiency and maximize oil recovery, requires application of advanced well completions that are guided by effective reservoir evaluation and management practices.Optimizing inflow profiles in horizontal wells requires good understanding of multiphase flow mechanisms, where the flow regimes are usually complicated due to stratification, slug flow, mist flow and/or other complex flow behaviors. Achieving better understanding of this multiphase flow mechanism was facilitated with the availability of the multiphase production logging tool (MPLT), which has been utilized extensively in this case study. This paper presents a summary of the results of a case study of 31 horizontal wells completed in a large carbonate onshore field, with the main objective to improve understanding of horizontal well inflow profiles and performance. For this case study, the areas of focus are inflow profile types, production performance and temperature log response. This paper concludes with lessons learned and practical recommendations to be considered for field development.

This paper presents the re-development strategy employed to recover attic oil from the highly-fractured crestal area of a carbonate reservoir. Optimum re-development strategies for the crestal area, along with planning and execution incorporating Best in Class (BiC) reservoir management practices are discussed.The crestal area was previously developed using full penetration vertical wells. After many years of continuous production and nearby injection, oil production rates in these crestal wells have declined with increasing water cut.The re-development strategy has been tailored to exploit this challenging opportunity and to maximize the production efficiently with selective placement of horizontal skimmer wells at the very top of the structure. Fit-for-purpose completion technologies were deployed to address the effects of the extensive fractures. Tapping oil continuously flowing into the crestal area by displacement, gravity, and capillary mechanisms, this re-development strategy has resulted in efficient and sustainable production.
