Abstract

PETRONAS completed well H-X on B field in Malaysia with a Digital Intelligent Artificial Lift (DIAL) gas lift production optimization system. This DIAL installation represents the first ever successful installation of the technology in an Offshore well for Dual String production. This paper provides complete details of the installation planning and operational process undertaken to achieve this milestone. DIAL is a unique technology that enhances the efficiency of gas lift production via downhole monitoring of production parameters informs remote surface-controlled adjustment of gas lift valves. This enables automation of production optimization removing the need for well intervention. This paper focusses on a well completed in November 2020, the fourth well to be installed with the DIAL technology across PETRONAS Assets. The authors will provide details of the well and the installation phases: system design, pre-job preparations, improvements implementation, run in hole and surface hook-up. For each phase, challenges encountered, and lessons learned will be listed together with observed benefits. The DIAL system introduces a paradigm shift in design, installation and operation of gas lifted wells. This paper will briefly highlight the justifications of this digital technology in comparison with conventional gas lift techniques. It will consider the value added from the design stage, through installation operations, to production optimization. This successful installation confirms the ability to implement the DIAL technology in a challenging dual string completion design to enable deeper injection while avoiding interventions on a well with a greater than 60-degree deviation. With remotely operated, non-pressure dependent multi-valve in-well gas lift units, the technology removes the challenges normally associated with gas-injected production operation in a dual completion well – gas robbing and multi-pointing. Despite the additional operational & planning complications due to COVID-19 restrictions, the well was completed with zero NPT and LTI. Once brought online, this DIAL-assisted production well will be remotely monitored and controlled ensuring continuous production optimization, part of PETRONAS' upstream digitization strategic vision.

全球首个成功安装数字智能人工举升刻度盘的双管柱——马来西亚海上无干预气举生产优化系统
马来西亚国家石油公司使用数字智能人工举升(DIAL)气举生产优化系统完成了马来西亚B油田的H-X井。此次DIAL装置是该技术首次成功应用于海上双管柱生产井。本文提供了为实现这一里程碑而进行的安装计划和操作过程的完整细节。DIAL是一项独特的技术,通过对生产参数的井下监测,为气举阀的远程地面控制调整提供信息,从而提高气举生产效率。这可以实现生产优化的自动化,而无需进行油井干预。本文重点介绍了2020年11月完工的一口井,这是PETRONAS资产中使用DIAL技术的第四口井。作者将提供井和安装阶段的详细信息:系统设计、作业前准备、改进实施、下入井和地面连接。对于每个阶段,遇到的挑战和吸取的教训将与观察到的好处一起列出。DIAL系统为气举井的设计、安装和操作带来了范式转变。本文将简要介绍与传统气举技术相比,该数字技术的合理性。它将考虑从设计阶段到安装操作,再到生产优化的附加价值。此次成功的安装验证了DIAL技术在具有挑战性的双管柱完井设计中的应用能力,可以实现更深的注入,同时避免对斜度大于60度的井进行干预。通过远程操作、无压力依赖的多阀井内气举装置,该技术消除了双完井中注气生产作业通常面临的挑战。尽管由于COVID-19的限制,增加了作业和规划的复杂性,但该井以零NPT和零LTI完成。一旦投入使用,这口dial辅助生产井将被远程监控,以确保持续的生产优化,这是马来西亚国家石油公司上游数字化战略愿景的一部分。
