Chariot Ltd. found gas in its Anchois-2 appraisal and exploration well on the Anchois gas project within the Lixus license, offshore Morocco.
The well was drilled to 2,512 m TD by the Stena Don drilling rig in 381 m of water. Comprehensive evaluation of the well was through wireline logging, petrophysical evaluation, and subsurface formation testing including reservoir pressures and gas sampling, sidewall cores, and well bore seismic profiles.
Preliminary data confirms the presence of significant gas accumulations in the appraisal and exploration objectives of the well, with a calculated net gas pay of more than 100 m, compared to 55 m in the Anchois-1 discovery well.
Gas Sand B appraisal target has calculated total net gas pay of more than 50 m in two stacked reservoirs of similar thickness. The upper reservoir is a continuation of a reservoir drilled in the original discovery well, with the lower reservoir being newly identified.
Gas Sands C, M, and O exploration targets were encountered with multiple gas-bearing intervals across a gross interval of 250 m measured distance with no water-bearing reservoirs identified, materially exceeding pre-drill expectations.
The previously discovered Gas Sand A was not targeted in the Anchois-2 well due to the intention of evaluating it in the subsequent Anchois-1 re-entry operations. The Anchois-2 well encountered gas bearing sands at this level, however, providing important additional subsurface data.
Chariot is operator of Lixus (75%) with partner ONHYM, the Office National des Hydrocarbures et des Mines (25%).
