Max-Drill, Drilling Performance Optimization Process. Significant Improve in Geothermal Drilling Performance

Abstract

Performance drilling is a big challenge in Oil & gas and geothermal drilling. Industry is trying to find the best way of understanding bit selection, motor, downhole survey, drilling parameter, ect. Objective is to reduce drilling cost by spent less drilling rig time. Chevron develops drilling optimization process call “Max Drill” which is wildly used in many businesses all over the world in oil and gas drilling. Geothermal Business also utilizes Max Drill process, specific for geothermal drilling which is understand as, a hard rock, low pressure and high temperature. As per April 2013, Salak campaign completed 6 steam cap producer(Included 1 multi lateral), two Deep liquid producer, one work over , and two brine injector wells (totally 10 drilling wells and one work over) with in 11 month of operation , which is approximate 3-4 month faster than the estimation. One of key factor is due to implementing “Max Drill” Process. The paper has objective to demonstrate to Geothermal Drilling industry understand the use of Drilling engineering and process to improve drilling performance.
