Drilling Optimization of a Selected Field in Kurdistan Region of Iraq

Abstract

Since the startup of petroleum drilling industry, the drilling companies and the drilling tools manufacturers have continuously focused their research to optimize for drilling through better tool production as well as applying techniques and methods those best serve in optimizing drilling for time save, better use of tools, safeguard the well and the formation and eventually provide for a major cost save. This paper is based on analyzing the drilling parameters of bit weight, rotation, rate of penetration as well as drilling hydraulics of three of the wells drilled by an operator in a selected field in Kurdistan. The research will apply optimization technique proposed and implemented by Simmons in 1986 to the drilling bits and parameters of these three wells and suggest drilling parameters in two scenarios for future wells if are to be drilled. The study will present the time save using each scenario and recommend best practice for future drilling.
