Every single oil, gas or geothermal well has a certain life cycle, starting from drilling phase, production, until the well must be shut-in. Well abandonment can be temporary or permanent, depends on its problem. Temporary well abandonment is caused by some factors such as well problem, infrastructure problem, and economical production. Well abandonment activity must be conducted depend on the qualified standard, which one of the ways is by using Norsk Sokkels Konkurranseposisjon (NORSOK) D-010. NORSOK D-010 is a standard or functional provision as minimum requirements for equipment or solutions used in the well. <br /> <br /> The purpose of this study is to evaluate NORSOK D-010 application in the temporary oil, gas or geothermal well abandonment activity in Indonesia. In order to achieve the goal, a study of an offshore well ‘X’ in Indonesia is arranged. That well has been produced for over 12 years. However, aging infrastructure has led to temporary abandonment of the well in 2006. This study will analyze the last well ‘X’ conditions contain of tubing, well barrier, wellhead, and christmas tree condition and also Remotely-Operated Vehicle (ROV) data report. This study is also subjected to the process of temporary well abandonment, which has been done in offshore well ‘X’. It will consist of operation process and all the equipment used in the operation. <br /> <br /> The result of this study is an evaluation of the temporary well abandonment activity in Indonesia based on NORSOK D-010 refers to well condition and operation process. This study shows that NORSOK D-010 is a proper and corrected standard for a reference in temporary well abandonment in Indonesia.
