The Ghasha mega-project is the world’s largest offshore sour gas development. The multi-billion-dollar project will play a vital role in meeting the UAE’s gas self-sufficiency objective, in line with ADNOC’s integrated gas strategy. Approved by the Supreme Petroleum Council (SPC), the integrated gas strategy aims to unlock and maximize value from Abu Dhabi’s substantial natural gas reserves.

The mega-project is estimated to hold significant recoverable gas reserves. When it comes onstream, the Ghasha mega-project is expected to produce more than 1.5 billion standard cubic feet (bscfd) of natural gas per day. With this production, it will be instrumental in providing electricity to more than two million homes in the UAE by around the middle of the decade.

The Ghasha mega-project draws on ADNOC’s long-standing sour gas expertise, including its Shah onshore ultra-sour gas field project, its pioneering work in the creation of artificial islands, and the wide and deep sour gas capabilities of its concession partners. It will further strengthen the UAE as a leading global hub for knowledge and experience in ultra-sour gas.

Expanding ADNOC’s leading sour gas experience, the company entered into strategic partnerships with global companies that have proven sour gas capabilities. To date, the concession has attracted significant foreign direct investment from four major partners: Italy’s ENI (25%), Germany’s Wintershall Dea (10%), Austria’s OMV (5%), and Russia’s LUKOIL (5%). With a concession term of 40 years as of November 2018, the project will further optimize costs and ensure that maximum value from gas resources is extracted, in line with ADNOC’s ambitious gas strategy.

The Ghasha ultra-sour gas concession comprises the Hail, Ghasha, Dalma, Nasr, Satah al Razboot (SARB), Bu Haseer, Shuweihat, and Mubarraz offshore sour gas fields in Abu Dhabi. As infrastructure was required to further develop, drill, and produce from the sour gas fields in the first phase of the Ghasha concession, ADNOC awarded the dredging, land reclamation, and marine construction contract to build multiple artificial islands to the UAE’s National Marine Dredging Company (NMDC). Valued at AED 5 billion, the project enables NMDC to construct 10 new artificial islands and two causeways, as well as expand an existing island, Al Ghaf.

The artificial islands are named after pearl diving sites in the area and capture the rich history of the region: Ghanem, Sawalem, Chananiz, Mudaifena, Reeah, Seebeh, Seemeh, Shalhah, Jzool, and Duroob.

The ambitious undertaking of building artificial islands for this project allows greater flexibility for an extended reach drilling and fewer wells, when compared to conventional offshore operations. In addition, the use of artificial islands will eliminate the need to dredge over 100 locations for wells and will provide habitats for marine life.

ADNOC has a proven record of developing artificial islands, including the construction of four artificial islands for the Upper Zakum expansion project. ADNOC’s Upper Zakum field is the second-largest offshore oil field and the fourth-largest oil field in the world.

The Ghasha mega-project will use smart technology across all operations so that ADNOC’s operators, technicians, and site personnel can remotely access key activities across the project. Not only does the digital approach optimize work procedures and strengthen data integration, but it also improves real-time decision-making from sub-surface to drill centers and ground facilities.

Ghasha is a perfect demonstration of how ADNOC has incorporated smart technology across the board. Here are some highlights:
  • The project’s remote facilities will be operated from a central control center in Al Manayif so that technical personnel can respond promptly whenever interventions are required. It will be one of the largest automation control systems in the Middle East, controlling all offshore and onshore operations. It is projected to handle information from more than 100,000 inputs and outputs that cover both analogs and digital.
  • The project is the first oil and gas project in the world that will be a 100% unmanned operation for offshore facilities. It will use high-tech sensors, drones, rail cameras, and inspection robots. All robots, drones, and other moving vessels will be micro-chipped and monitored from the central control room located onshore.
  • The project will use artificial intelligence such as predictive maintenance for all critical rotating equipment. It will also see the deployment and maximization of the Digital Twin technology to enhance onshore and offshore operation efficiency. The Digital Twin is a digital representation of the assets and process facilities, which will add value to production planning, production efficiency, performance, and personnel. It will capture, aggregate, analyze operational data, improve production system efficiency, as well as monitor and report assets performance.
  • The project ensures that the safety of all offshore personnel is a top priority. In addition to the digital handheld devices for data access, reporting, digitized Permit to Work (PTW), the vital signs and location of personnel are monitored in real-time from the control room so that they are safe from harm at all times especially when they are working in remote areas or hazardous conditions.
For the first time in the oil and gas industry, an Integrated Project Delivery (IPD) approach was implemented from the concept phase to the execution phase. ADNOC ensured that its stakeholders were involved from the very beginning so that they could cumulatively improve the project efficiency in terms of scope quality, schedule, and cost.

In addition to ADNOC and its Ghasha concession partners, stakeholders included various governmental organizations, FEED bidders, EPC contractors and sub-contractors, drilling operators/service providers, and environmental agencies. Representatives from each stakeholder participated in key meetings and workshops from the onset of the project jointly reviewed the project scope, shared lessons learned, and identified opportunities to improve processes.

The Ghasha mega-project is a key enabler of ADNOC’s In-Country Value (ICV) Program, which aims to nurture new local and international partnerships by catalyzing socio-economic growth and creating job opportunities for UAE nationals. Over the project’s lifetime, an expected ICV of 40% will flow back into the UAE economy, further driving the UAE’s socio-economic development.

During the peak construction period, the project will comprise 30,000 to 40,000 contractor staff and is expected to employ over 1,500 people. Construction and drilling contracts have defined requirements to drive Emiratization and open up new opportunities for talented young graduates in the next few years. In the production phase, it has been estimated that hundreds of job opportunities will be created for UAE nationals.

Technip Energies awarded a contract to update FEED for Ghasha mega project

Technip Energies (PARIS:TE) has been awarded a contract by the Abu Dhabi National Oil Company (ADNOC) to update the Front-End Engineering Design (FEED) for the Ghasha mega project including accelerating the integration of carbon capture into the development. This project is part of the Ghasha Concession wherein ADNOC’s strategic partners are Eni (25%), Wintershall Dea (10%), OMV (5%), and LUKOIL (5%).

The project aims to develop the untapped oil and gas reserves from the Ghasha Concession fields which is the world’s largest offshore sour gas development. The Concession area is expected to produce over 1.5bscfd(1) of natural gas, as well as condensate and oil. In addition, the CO2 capture, dehydration and export shall be an integral part of the project facilities, thereby reinforcing ADNOC’s decarbonization and sustainability commitments.

The start of production from the concession is expected in 2025, ramping up to full production by the end of the decade. The overall objective of the updated FEED will be to further optimize the project costs for this development as well as to accelerate the integration of carbon capture.

Marco Villa, Chief Operating Officer of Technip Energies, stated: “We are very proud to have been awarded this FEED which will be one of the largest ultra-sour gas project Technip Energies has worked on. This award is recognition of the strong competencies in gas processing as well as the relationship and trust that ADNOC has with Technip Energies for such strategic project. As part of our energy transition journey, we will contribute to a robust design of carbon capture and transportation for enhanced oil recovery, a critical element of this project. For the past four decades, we have been committed to ADNOC through added value services and continued our commitment to expand local execution capabilities and enhance In-Country Value.”
