Drilling of Tendrara well TE-7 commences

Oilfield Technology,

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

Following the recent success of the first Tendrara well (TE-6), a sub-horizontal appraisal well (the company's second well on the licence; TE-7) was spud on 25 August 2016. The well objectives of TE-7 include proving sufficient gas volumes and well deliverability to enable finalisation of the field development plan and a concession application and demonstrating the benefits of sub-horizontal drilling, which is expected to be implemented as the production well concept for Tendrara.

The TE-7 site is approximately 830 m to the Northeast of TE-5 and hence some 1.6 km from the TE-6 site. Drilling is planned to reach a total measured depth of 3440 m with specific tools being used to geo steer the well at close to an 88 degree angle inside the TAGI reservoir to ensure a horizontal drain of between 600 and 900 m. The sub-horizontal section will run to the North, parallel to the minimum horizontal stress observed in TE-6.

The TE-7 drilling programme is anticipated to follow key three phases:

  • Drilling and logging (approximately 54 days).
  • Completion and stimulation (approximately 30 days).
  • Clean-up and initial well testing (up to 10 days).
  • The company looks forward to updating shareholders on achievement of each of the three casing points and achievement of total depth. The final results of the well will be announced after the initial well test.

    An extended well test will follow for approximately 70 days thereafter to confirm production sustainability and to aid comprehensive field development planning.
