The project involves the development of the Yellowtail and the Redtail discoveries located in the eastern half of the Stabroek Block. It will be a subsea development tied back to a new floating production storage and offloading FPSO vessel. Esso Exploration and Production Guyana EEPGL a subsidiary of Exxon Mobil is the operator and holds 45 interest in the Stabroek Block while Hess Guyana Exploration and CNOOC Petroleum Guyana hold 30 and 25 interest respectively. The project partners submitted an environmental impact assessment EIA report of the project to Guyanas Environmental Protection Agency EPA in October 2021 and awarded the contract for front-end engineering and design FEED of the FPSO in November 2021. Subject to approvals from the Guyanese authorities and final investment decision FID by the project partners the Yellowtail offshore development is expected to start production between 2025 and 2026 and continue to be operational for at least 20 years. Yellowtail development project location and discovery details The Yellowtail Development will be located 203km north-east off the coast of Georgetown Guyana. The water depth in the project area ranges from 1700m to 1900m.The Yellowtail field was discovered by drilling the Yellowtail-1 exploration well in April 2019. It was Exxon Mobils 13th discovery in the Stabroek Block.Drilled by the Noble Tom Madden drillship to a depth of 5622m the Yellowtail-1 well encountered 89m of oil-bearing sandstone reservoir in the Turbot area of the Stabroek Block.Yellowtail-1 was followed by the Yellowtail-2 exploration well and the Redtail discovery through the Redtail-1 exploration well in 2020. The Yellowtail-2 exploration well encountered 21m of net pay in newly identified oil-bearing reservoirs among the original Yellowtail-1 intervals.The Redtail-1 well located 2.5km north-west of the Yellowtail discovery encountered 70m of high-quality oil-bearing sandstone reservoir in September 2020.Yellowtail project development planThe Yellowtail development project will be a subsea development with up to 67 wells including production water injection and gas re-injection wells drilled from six drill centres.The subsea system will include 51 enhanced vertical deepwater trees EVDTs and 12 manifolds along with associated controls and tie-in equipment.The subsea production water injection and gas re-injection facilities will be clustered around drill centres requiring fewer manifolds flowlines and umbilicals.Yellowtail FPSO detailsThe Yellowtail FPSO is planned
