Gas-backed reliability, Karish offshore field cements Energean’s core asset role

Energean’s Karish offshore gas field, developed around the Energean Power floating production, storage and offloading unit in the Eastern Mediterranean, has quietly become one of the company’s flagship upstream assets, supplying Israel with natural gas under multi-year supply contracts and adding liquids output from associated condensate.

How the Karish field and Energean Power FPSO deliver gas into Israel

Karish is located about 90 kilometers off the Israeli coast in water depths of roughly 1,750 meters, with subsea wells tied back to the Energean Power FPSO that processes, stores and exports gas and liquids via pipeline to shore. First gas from Karish was achieved in late 2022 after a multi-year development phase that involved drilling production wells, installing subsea infrastructure and towing the FPSO from the construction yard in China to its operating location offshore Israel. According to Energean, the FPSO has a nameplate gas processing capacity of up to 8 billion cubic meters per year, with flexibility to handle liquids streams from the field’s condensate output. The offshore hub is designed not only to monetize the Karish reservoir itself but also to act as a tie-in point for the nearby Karish North discovery, potentially enabling incremental volumes without replicating full surface facilities.

The field’s output is sold primarily into the Israeli domestic market under a portfolio of long-term gas sales and purchase agreements with power generators and large industrial customers, providing a relatively visible revenue stream that is less exposed to short-term spot price swings than pure merchant sales. These contracts typically include pricing formulas linked to fuel benchmarks such as Brent crude or alternative fuels used in power generation, creating an indexation mechanism that can reflect wider energy market trends while giving buyers more predictable cost structures over the contract term. Energean highlights the role of Karish as a cornerstone of Israel’s gas supply mix, supporting the country’s continued shift away from coal-fired power toward gas-fired generation with lower local emissions and more flexible dispatch. For Energean, the field diversifies its portfolio beyond legacy assets in the Eastern Mediterranean and helps anchor its production base with a large, long-life project that can support future investments.

On the technical side, the Energean Power FPSO development drew on global offshore engineering capabilities, including construction and integration work in Asia followed by a sail-away and hook-up campaign in the Mediterranean. The FPSO solution allows for processing and storage of hydrocarbons offshore without the need for a fixed production platform, which can be advantageous in deep water and in areas where onshore infrastructure is limited or subject to permitting constraints. By routing dry gas from the FPSO into Israel’s national transmission system via a dedicated subsea export line, the project effectively connects offshore reserves directly to local demand centers, reducing dependence on imported fuels and contributing to energy security. Liquids produced alongside the gas are stored on the FPSO and offloaded to shuttle tankers, adding a condensate revenue stream that can improve the project’s overall economics.

Energean continues to evaluate further optimization and expansion options around Karish, including potential additional drilling and phased development of Karish North that could utilize spare FPSO capacity if reservoir performance and market conditions justify it. Beyond the immediate field area, the company and its partners are also active in exploration and appraisal work in other Mediterranean licenses, reflecting Energean’s broader strategy to build a regional gas portfolio that can serve both domestic and export markets over time. From a risk perspective, offshore developments of this scale are exposed to commodity price cycles, regulatory changes and geopolitical dynamics, especially in a region with complex maritime boundaries, but long-term contracts and physical integration into Israel’s grid provide a stabilizing counterweight for the Karish project. For Israeli buyers, securing contracted volumes from Karish helps diversify supply sources and supports planning for generation capacity and industrial demand over the coming decade.

Within Energean’s portfolio, Karish is positioned as a key production growth driver and cash flow contributor, following earlier investments in assets around the Mediterranean that helped establish the company’s upstream footprint. The company is publicly listed in London, where its shares trade under the ticker ENOG, giving equity investors direct exposure to the performance of the Karish development and other projects. Shares of Energean (ISIN GB00B753SF33) closed on the London Stock Exchange at £7.36 on June 15, 2026, reflecting market expectations for the company’s gas-weighted strategy and ongoing execution at Karish and adjacent Mediterranean licenses.
