Well construction specialist DeltaTek Global announced Wednesday it has been awarded a contract from Energean Oil and Gas to support well construction at the Karish deepwater project offshore Israel.
DeltaTek said it will provide optimization services using its proprietary SeaCure cementing technology for all 20-inch surface casings, which will be drilled from the Stena DrillMAX in approximately 1,750m of water. DeltaTek will initially deploy SeaCure in four wells in the first quarter of 2019.
SeaCure delivers stabbed-in, inner string cementing for subsea wells. According to DeltaTek, the technology provides a range of cost- and time-saving benefits to drilling and field development operations, including elimination of shoetracks and clean out runs, improved cement placement and reduced displacement, offline casing pressure testing and improved drill out performance, with minimized risk of bottom hole assembly damage.
“The deployment of the SeaCure technology on our deepwater surface casing string cement jobs helps us to efficiently verify the integrity the surface casing through eliminating the operational risk of a failed shoe track,” said Simon French, Well Delivery Manager at Energean Oil & Gas. “Elimination of the shoe track drastically cuts down drill out times and saving money. The application offers a very elegant solution to our technical challenges.”
DeltaTek CEO Tristam Horn said the project award is the company's first large-scale international contract.
“SeaCure has been brought to market quickly, thanks to the support of our industry partners and the technology’s proven rig time saving ability. Adoption from major operators and successful field deployment results continue to demonstrate the efficiencies SeaCure can deliver and as is a genuine time and cost saving solution for offshore cementing,” he said.
“2018 was an incredible year for DeltaTek and we plan to continue building on those successes as we move into 2019,” Horn said. Energean Israel is the 100 percent owner and operator of the Karish lease, as well as the Tanin lease 40 kilometers away. The fields contain 2.2 TCF of natural gas and 31.8 million barrels of light hydrocarbon liquids independently audited 2P reserves plus 5.4 BCM of gas and 1.0 mmbls of liquids 2C resources. NSAI has audited 2.94 TCF of gas plus 78.8 mmbls of liquids unrisked prospective resources. According to a CPR produced by NSAI in June 2018, the Karish Field contains 282.2 mmboe 2P reserves plus 34.7 mmboe 2C resources.
Energean is developing both fields using a floating production storage and offloading unit (FPSO) that will be installed 90 kilometers offshore, making it the first FPSO ever to operate in the Eastern Mediterranean. The FPSO, which is being built by Cosco in Zhousan, China, will have a gas treatment capacity of 800 MMscf/day (8 BCM/per annum) and liquids storage capacity of 800,000 bbls.
Capex for the first phase of the Karish development is estimated at $1.6 billion.
Production from the field is expected to commence in the first quarter of 2021.
