Ammerlaan Geothermie doublet delivery

Project Description

Ammerlaan Geothermie B.V. has drilled two wells forming a geothermal doublet for district and greenhouse heating. Both wells have long tangent sections @ 60 degrees. Both wells are drilled successfully to TD . Installation of liner over reservoir was difficult. Both wells required a cased hole sidetrack to successfully install the liner over the reservoir.

Challenges

High angle wells (60 deg inclination), Small location, Long middle section (1800m).

Role of WEP

Well Engineering, Procurement, Drilling Supervision and Support during execution.
