Drilling for heat comes with its own set of challenges, demanding rigour in planning and execution to assure success in a sensitive commercial environment. Best practice, derived from lessons learned on the world’s most challenging wells ensures drilling projects are developed sustainably.
The physics of how cuttings move from the bottom to the top of the well does not change in relation to what is being drilled. Operational requirements will vary according to hole size, inclination, the drill string and subsurface pressure limits. From experience of drilling the world’s longest wells, Merlin’s onsite advisors are experts in ensuring that the practises and procedures employed on your Geothermal well are consistent with what is done internationally in other environments, getting you up the learning curve quickly and helping to avoid mistakes.
Geothermal wells require excellence in execution. These developments are often characterised by marginally positive project value with payback periods Stretching into decades. Problems executing wells, leading to cost over-runs are very likely to push a marginal project over the edge. Merlin’s advisors take a proactive approach to well delivery and performance management onsite. They support our clients Drilling Supervisor in ensuring that focus never deviates from what the well needs at any given point.
Having an additional pair of experienced eyes at the well is cheap insurance. Economic conditions have conspired to create an inexperienced labour force across all aspects of the drilling business. Merlin’s onsite personnel typically have 20 years plus of experience in well execution, often as Drilling Supervisors, or highly experienced senior service hands. This knowledge allows us to see problems developing before they become critical, allowing us to guide and mentor personnel at the rigsite.
