PLASMABIT – Innovative drilling and casing system

Abstract

Currently, the price of the geothermal well is increasing with its depth exponentially due to friction, tripping and other negative features. PLASMABIT technology is being developed to drill with a constant speed, without need to change a drilling bit on regular basis, working in a HPHT environment. Therefore the drilling cost using PLASMABIT is rising only linearly with the drilling depth. As a result, the overall drilling cost, infrastructure cost and drilling time are radically cut. PLASMABIT technology is based on high-energy electric plasma, thermal treatment and thermohydraulic explosive process for the fragmentation with the aim of increasing the productivity of the drilling process. The key effort is to develop the technically and economically efficient technology with constant penetration rate for the deep drilling.
