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.
