WATER-BASED DRILLING FLUID DEACIDIFICATION PROCESS AND APPARATUS

摘要

A method and an apparatus is provided for use in an underbalanced drilling process using exhaust gases wherein some constituents of the exhaust gas combine with water to form acids. The present invention provides a means of deacidifying drilling fluids. The pH of the drilling fluid is monitored and adjusted to prevent corrosion of equipment by acidic drilling fluids. The drilling fluid may also be optionally treated with anti-scaling agents. The drilling fluid may be a gas, a liquid or a combination of both or it may be gasified oil based drilling fluid.
