First Successful Innovative Approach of Pad Drilling Implementation in a Brown Onshore Oil Field in the United Arab Emirates

摘要

Pad Drilling Concept was developed to increase and sustain the production rate one of the UAE Brownfield Onshore Oilfield (BO) from four different reservoirs. The surface facilities of the field will accommodate total of 80Mbd and technical rate of 96Mbd. The project scope was redefined in 2016 to enhance the overall project's cost and further study on newly developed reservoir (Reservoir "A"). The project came into execution since January 2018 and so far, 100 plus wells drilled successfully. Therefore, to accommodate the required number of wells based on the company production target ahead of time, the planning stage represented as per 2018-2022 business plan is maintained with first oil in Q1 2020. The Full Field Development Plan (FFDP) is to deliver a total of 210 wells to sustain the production rate beyond 2024. Thus, the selected scheme for the FFDP which is planned to be artificially lifted is based on water injection and water alternating gas injection (WAG). The Key aspects of the project are: 1. Partial development of Reservoir "A" 2. Sensitive environmental area 3. Brownfield development in Simultaneous Operations (SIMOPS) conditions. 4. Directional Drilling trajectory and anticollision constrains. Critical success factors for this project are: 1. Integrated Project Management Team with dedicated full time resources 2. Appointment and selection of competent Engineering contractor to develop the facilities within the target time. 3. Timely approval and implementation of project's milestone. Thus, the benefits from the project for this Field are: 1. Optimized Field Development Plan; 2. Prevent congestions & access constraints; 3. Standardization of HSE & Operations; 4. Economical Surface Facilities Management. 5. Rig days and cost saving. 6. Sweep Efficiency of the reservoir. 7. Early completion / production of project.
