European and African focused upstream company Sound Energy has commenced drilling of the second well at Tendrara, onshore Morocco.

After the successfully drilling the first Tendrara well (TE-6), a sub-horizontal appraisal well was spud later in August on the TE-7, the second well in the license.

The Tendrara permit is located in the Figuig Province, North-East Morocco, 120km from the GME pipeline, connecting Algeria and Morocco to the Spanish/Portuguese gas grids.

Sound Energy will now aim to demonstrate the advantages of sub-horizontal drilling of the TE-7 well, which is approximately 830m to the northeast of TE-5 and 1.6km from TE-6.

Additionally, the well will prove sufficient gas volumes and deliverability prior to finalization of the field development plan and concession application.

The well is planned to be drilled to a total measured depth of 3,440m. Tools will also be used to geo-steer the well at an 88° angle inside the Trias Argilo-Gréseux Inférieur (TAGI) reservoir to ensure a horizontal drain of between 600m and 900m.

The sub-horizontal section will run to the north, parallel to the minimum horizontal stress observed in TE-6, the company said.

Sound Energy plans to complete the TE-7 drilling in three phases. The first involves drilling and logging for approximately 54 days, which is followed by completion and stimulation for approximately 30 days. The final phase will include clean-up and initial well testing for up to 10 days.

Following completion of the initial well test, the company will undertake an extended well test for around 70 days to confirm production sustainability and to aid comprehensive field development planning.
