Successful Pilot Implementation of 15K psi HPHT Multistage Stimulation Completion Technology in KOC’s Jurassic wells

Summary The development of HPHT reservoirs in Kuwait’s Jurassic formations poses significant challenges. Conventional completion methods often fail in these complex environments. MultiStage Stimulation Completion Technology addresses this by enhancing wellbore stimulation and hydrocarbon recovery. It allows precise, zone-specific stimulation, effectively handling the complexities of HPHT reservoirs. The MSSC functions by using frac sleeves and open-hole packers to isolate different sections of the wellbore. This compartmentalization allows for selective stimulation of individual zones, maximizing reservoir contact and improving production outcomes. By facilitating multiple fracturing stages in a single well completion run, this technology optimizes the stimulation process and reduces operational downtime. The ability to treat specific reservoir sections independently is crucial in HPHT environments, where pressure variations and reservoir complexity require a more targeted approach. In a pilot phase conducted by Kuwait Oil Company (KOC), this technology was implemented in several Jurassic wells. The pilot focused on overcoming traditional completion limitations and improving well productivity through targeted stimulation. The wells involved in the pilot exhibited significant improvements in oil and gas production, demonstrating the effectiveness of multi-stage stimulation in unlocking difficult reserves. This marked a significant milestone in KOC’s efforts to enhance recovery in HPHT fields, laying the groundwork for future applications of the technology. The success of the pilot phase highlighted this technology’s potential as a key solution for KOC’s Jurassic reservoirs. By tackling challenges like heterogeneity and reservoir compartmentalization, the multi-stage approach has proven adaptable to the region’s complex geology. Additionally, its ability to perform multiple fracturing stages in one run has reduced completion time, speeding up well delivery without compromising production efficiency. The potential for full-scale deployment of Multi-Stage Stimulation Completion Technology is significant. Its successful application in the pilot phase has demonstrated that this technology can offer substantial benefits to KOC’s broader field development strategy. Full-scale implementation could not only improve production across numerous wells but also contribute to achieving KOC’s long-term production targets, particularly in HPHT environments where maximizing reservoir efficiency is critical. This paper summarizes the design of multi-stage stimulation, its successful pilot application, and the benefits seen in full-scale implementation. By improving completion efficiency and boosting production rates, this technology could significantly impact HPHT reservoir development strategies. Pilot results suggest it may be a game-changer for unlocking additional reserves in complex reservoir environments.
