JOURNAL FREE ACCESSIn the realm of petroleum exploitation, technology innovation, as well as capital investment and human resources, will play a crucial role in securing global energy supply over the coming decades. Innovation, however, does not spontaneously occur; rather, it must be induced on purpose. This article aims at prompting us to be involved in the process of inducing innovation.
To clarify the practical significance of innovation to individuals or organizations, the concept of commitment paradigm is introduced, with which the innovation can be categorized into two : universal and custom-made. For individuals with the company commitment, custom-made innovation is an appropriate and reasonable target to decide on. Universal innovation, on the other hand, tends to be accomplished by those with higher commitment that transcends company towards community, mankind, and the Earth.
Individuals and organizations must grade themselves on their degree of commitment to encourage the practice of inducing innovation. At the same time, for the sake of national interest, a center for universal innovation must be founded with a thorough support from a variety of energy-related sectors. With these efforts, it becomes possible for technology to deliver its promises.View full abstractDownload PDF (1428K) -

JOURNAL FREE ACCESSNatural asphalt produced from oil bearing region in Northern Japan has been used as a glue to fix shaft and knife during the Jomon period (5000∼2300 years ago). The 121 oil and gas fields were discovered in Japan since 1888, and the oil and gas productions are 15,700 bopd and 304 mmcfd from 19 fields in the recent. The production rate is only 0.3% and 3.7% of the total consumptions of Japan respectively. In the “Japanese New Energy Policy”, the percentage of equity oil produced by Japanese oil companies in the world will be increased from 17% to 40% of Japanese consumption in 2030. The old Japanese petroleum technologists over than 40 years old dominate 62% of the total 2,500 technologists. The young peoples are lack due to a few employments since 1990. We must retain and recruit young people in the upstream industry, and also the older professionals will need to transfer the skill and knowledge to young people. We will challenge to discover new oil and gas reserves in the frontier area and to develop unconventional petroleum resources by technological innovation. We will attempt to introduce the upstream business at universities, science/petroleum museums and the producing oil and gas fields as a volunteer.View full abstractDownload PDF (13411K) -

JOURNAL FREE ACCESSIn 1987, in order to achieve an efficient 6,000m well drilling, the first introduction of OBM to the domestic field in JAPEX was considered, but temporarily suspended due to Japanese rules and regulations and the development of HPHT WBM was in sight.
Recently, extended reach, horizontal, deepwater and deep HPHT wells are come to demand in worldwide basis and in JAPEX extended reach or highly deviated 3D domestic wells are programmed and SBM are again necessitated to introduce to Japan.
Having reexamination of which consist of facilities to correspond with Japanese regulation, logistics, rig modification, crew training and engineering of both mud cooling and well control, JAPEX achieved usage of SBM in Japan in 2006 for Akebono SK-4D well.
The Akebono well demonstrated a total qualified technology in JAPEX and her subsidiaries in the course of utilization of SBM.
With regard to the actual operation, encountered lost circulation and low ROP in the deep coal bearing formation and hence actual operational days had to be lengthened in spite of being given a good hole condition compared with the past WBM experience.
SBM are to be utilized for next well in 2007, JAPEX group, accordingly, have to overcome several outcomes arising from Akebono in order to be further proficient in utilizing SBM and establish or prove its profits for future operation.View full abstractDownload PDF (7698K) -

JOURNAL FREE ACCESSTeikoku oil Co. Drilling Department has tried to improve and transmit drilling and safety technique. Three methods such as “Standard operation procedure”, “Risk Assessment” and “Near miss accident map” are introduced in this paper.
“Standard operation procedure” is the record of the basic required knowledge for workers in the drilling department. Most of them have that knowledge already, but some of them do not have it. All of them can get above knowledge by reading the record, and this will protect them against accidents caused by human errors due to forgetting and misunderstandings.
“Risk Assessment” is used for finding hazards from each operation before having disaster.
“Near miss accident map” is the grouping of near miss accidents that were reported in the past. Drilling crew use the tool for foreseeing hazards in each operation, and a supervisor can tell hazards to drilling crew by using this tool.View full abstractDownload PDF (2117K) -

JOURNAL FREE ACCESSIn DESC (Design and Evaluation Services for Clients) service, a service company engineer works in the client office and with oil company engineers to analyze wells that are candidates for production improvement and to develop treatments to enhance well productivity. For both service company and oil company, the DESC program provides significant benefits. DESC engineers are dedicated to serving a single customer, cutting cost, improving quality and raising productivities. They contribute years of experience in completion engineering, and when they move into an oil company office, they are practically self-sufficient, bringing their own networked workstation, a bookshelf of dedicated software and a modem. The oil company provides an office with a desk and chair, phone and electricity, and allows access to well files and company experts.
The oil company gets a seasoned engineer with a fresh perspective. The service company gets a richer understanding of client needs and improved access to opportunities for well treatment services. Both parties benefits from daily contact that builds trust, which stimulates the cross-pollination of ideas. This candid exchange results in earlier acceptance of new ideas and faster development of solutions. As management consultants say, it's a win-win scenario.
There are several practices and tools what service company engineers use to share knowledge and experience. They are important factors to enhance operation and production efficiency in tougher drilling environment.
This paper presents how the DESC program works, and a tour of case studies to see how DESC engineers operate day to day.View full abstractDownload PDF (4248K) -
