本文回顾了尼日利亚阿帕尼油田采用的精益建设管理流程，描述了油气实施阶段，并审查了该油田的资产开发计划。本文的研究结果有望帮助理解如何有效地恢复和开发新的油气资产（包括预钻井和封堵井口）。
Apani油田位于OML53南部尼日尔三角洲沉积盆地的陆上。Apani-01井随后于2006年被封堵并废弃。
Apani边际油田资产开发计划最终确定了钻井地点，但由于在地下10米处回收预先钻好并封堵的井口存在诸多挑战，因此在项目执行阶段采用了一种非常规方法。工程和项目团队认为，确定设计和施工的最佳工程条件至关重要，这一过程考虑了钻机设备占地面积、钻机下部和上部结构的累积载荷分析、辅助设备逐台载荷计算、振动分析、应力分析、总体布置和材料选择。
Apani 钻井场选址的首个项目位于河流州，项目进度迅速，并在项目批准后四个月内实现了首次采油。作者的工程和项目团队确保该项目遵循了与项目管理知识体系 (PMBOK) 推荐实践相当的方法。
钻井场地准备阶段面临的主要项目挑战之一是获取关键物资和设备的时间太短。
The complete paper reviews the lean-construction-management processes adopted in Nigeria’s Apani field, describing the oil and gas execution phase and examining the field’s asset-development plan. The findings of this paper are expected to provide an understanding of how new oil and gas assets (including predrilled and plugged wellheads) should be effectively recovered and developed.
The Apani field is onshore in the Niger Delta sedimentary basin in the southern part of OML53. The Apani-01 well was subsequently plugged and abandoned in 2006.
The Apani marginal-field asset-development plan, culminating in drillsite-location preparation, adopted an unconventional approach during the project-execution phase because of challenges inherent in recovering predrilled and plugged wellheads 10 m below ground level. The engineering and project team established that it was important to determine optimal engineering conditions for design and construction, a process that took into consideration rig-equipment footprint, cumulative load analysis of rig sub- and superstructure, auxiliary equipment unit-by-unit load calculations, vibration analysis, stress analysis, general arrangement layout, and materials selection.
The first Apani drillsite-location preparation, in Rivers State, was implemented on a fast-track schedule and achieved first oil production within 4 months of project sanction. The authors’ engineering and project team ensured that the project followed a methodology equivalent to project-management body-of-knowledge (PMBOK) recommended practices.
One of the main project challenges during the drillsite-location preparation phase was the short amount of time available to acquire critical supplies and equipment.
