Drilling operation cost in development activities for oil and/or natural gas occupies large portion of the total project cost. Several approaches have been discussed for years in order to reduce the drilling operation cost.
This paper represents an interactive approach towards achieving the Technical Limit for drilling operations, using an optimized philosophy characterized by sound engineering fundamental practices and their application during the planning implementation phases for drilling operations. This approach is then applied to Organizational Learning templates developed by Japan National Oil Corporation and Frontline Group, Organizational Learning Division.
The fundamental premise is that all drilling operations are similar in that the irrefutable basic physical principle of force governs dynamic operations in the enchmarking processes of such as ROP, hydraulics etc.
This principle is applied to METI exploratory test well “Chikappu” operation in the Heisei-12- year drilling Campaign and in a workshop conducted in Tokyo, Japan with a team of engineers comprised of Japan National Oil Corporation, and Frontline Group.
The purpose of the workshop is to deliver a well construction plan, using a targeted approach beginning with the historical analysis of applicable offset information and global benchmark data, applying optimized physical principles to each dynamic operation.
The assumptions are as follows,
(1)The time analysis of offset information on METI exploratory test well “Tempoku” operation in the Heisei-5-year drilling Campaign results in Technical Limit Time as of 40%, Invisible Lost Time as 40%, and Non Productive Time as 20%.
(2)The reality of one bit for one hole section has been achieved in each hole section, and can routinely be achieved by today's available technology.
(3)Each hole section would be treated as if minimum mud weight trends were applied to optimize horsepower.
