Anchois gas field, located in the Lixus licence, is the first exploratory success offshore Morocco.

The Lixus licence is jointly owned by operator Chariot Oil and Gas (75%) and Office National des Hydrocarbures et des Mines (ONHYM, 25%).

The feasibility study and the Morocco gas market monetisation assessment for the Anchois gas project development was completed in June 2019.

An environmental impact assessment for the project is currently being carried out, while appraisal activities are expected to start in 2020.

Anchois gas field location

The Anchois gas field is located in the Tanger-Larache exploration area of the Lixus licence, 40km off the coast of Morocco, in the Atlantic Ocean.

The Lixus licence is situated 30km north of Chariot’s Moroccan acreage. It spans across an area of approximately 2,390km² with water depths ranging up to 850m.

Chariot has found five more prospects within the Lixus licence with geological properties analogous.

Anchois field discovery, geology, and reserves

The Anchois field was discovered by the Anchois-1 well drilled in March 2009. The discovery was made by Dana Petroleum along with its partners Repsol and ONHYM.

The discovery well was drilled to a total depth of 2,435m in a water depth of 388m using the Pride North America rig. It encountered two intervals of gas-bearing sands and a combined gas column of approximately 90m, with estimated net gas pay of 55m.

Gas at the Anchois field is held in turbidite reservoirs of the tertiary age. The field is estimated to hold an estimated 2C contingent reserves of 307 billion cubic feet (bcf) and a prospective resource of 116bcf, with estimated total recoverable resources of 423bcf.

The field will undergo seismic reprocessing in 2019, followed by drilling of the Anchois-2 appraisal well in 2020.

Anchois field development details

The Anchois field development will be carried out in phases to supply gas to different parts of the Moroccon gas market.

The first phase development will include the drilling of four production wells, which will be tied into a subsea manifold. One of the four wells is expected to be drilled during the appraisal stage and later completed as a producer.

Additionally, the first phase will involve the installation of a 14in-diameter, 40km-long subsea flowline with control umbilical to the subsea manifold, construction of an onshore central processing facility for exporting gas, and a 14in-diameter onshore pipeline for gas export.

The phase two development plan will include additional wells to tie-in the Anchois W, Anchois WSW and Anchois SW areas of the field into the subsea manifold. It will be financed using the cashflow generated from first phase production.

Gas transportation details

Gas will be supplied domestically and internationally via the Maghreb-Europe gas (MEG) pipeline. The MEG pipeline extends across Morocco, connecting the Hassi R’Mel gas field in Algeria to the Strait of Gibraltar and the Iberian Peninsula, merging into a network of European gas pipelines.

Drilling equipment details

Pride North America is a drilling rig, which was built by Friede & Golldman in 1998. It is currently known as ENSCO 5006 and is classified as an ABS with Maltese Cross 1A1 Column Stabilised drilling unit.

The rig can operate in a maximum water depth of 7,500ft to a drilling depth of 25,000ft. It is equipped with a Derrick loadmaster and can accommodate 120 people.

Contractors involved

Netherland Sewell & Associates, an oil and gas consulting firm based in Texas, US, was selected to prepare the independent Competent Persons Report for the Anchois gas field.
