Ghasha Offshore Processing Plant ( GOP ) Project
The Hail & Ghasha Development (HGD) Project will develop the untapped oil and gas reserves from the highly sour Hail and Ghasha fields. Production is targeted to start by Q4 2027 with sustainable production of 1 BSCFD of Raw Gas, and max production of 82.5 MSBPD of Oil, 76.3 MSBPD of Condensate.
Project Overview:
- The Hail and Ghasha fields are situated offshore Abu Dhabi about 140 km away from Abu Dhabi mainland in water depths varying from 0 to 15 meters.
- The Hail and Ghasha Project Offshore Package (EPC 01) comprises four Offshore Drilling Centers (DCs), Subsea Pipelines, Umbilicals, Power Cable Connections, Seawater Intake Structure, Bridges, Risers, Flare Structure, facilities at Ghasha Offshore Processing Plant (GOP).
- The HGD Project will be executed in a single phase approach. It will start production from three Drilling Centres (Reehah, Jzool & Seebah) in Ghasha Field to GOP and from Gaff Island in Hail Field to OPP.
- Remaining Drilling Centres, gas injection, and other associated facilities will be developed in future to sustain production from Hail & Ghasha fields.
Purpose and Objective of the Project:
- Project objectives are the engineering, procurement, fabrication, construction, pre-commissioning, commissioning and start-up of the Offshore Package facilities.
- The plant design is based on a modularization approach with definition of 29 Pre-assembled Units (PAU), 81 Pre-assembled Racks (PAR) and 13 Pre-assembled Buildings (PAB), along with other minor modules such as MOV skids and pre-assembled rack frames (PAF), pre-assembled stairs (PAS).
Intended Use and Operational Significance:
- The HGD Offshore Package facilities are intended for the oil and gas production, of strategic importance to the Emirate of Abu Dhabi.
- The plant and selected materials are designed to comply with the highly sour raw gas feedstock whose expected composition is characterized by a hydrogen sulphate concentration in excess of 30%, which represents one of the major challenges of the Project.
