JOURNAL FREE ACCESSIwaki-oki oil exploration commissioned Teikoku oil to remove the conductor pipe and abandon wells on Iwaki-oki offshore platform. The removal operation of conductor pipes is the first time for us, therefore we adopted the service company operational skills which is the removal operation of conductor pipes on the North West Hutton offshore platform.
From an environmental point of view, we made a plan to wash out shells from the conductor pipe during the operation.
After trial and error for establishing the way of operation, we completed to remove all pipes from 15 gas extension wells. As a result, we can shorten the period of operation by 23 days.View full abstractDownload PDF (3998K) -

JOURNAL FREE ACCESSIn recent year, domestic drilling activities of Japan Petroleum Exploration (JAPEX) are rapidly increasing. To execute such demand, SK engineering (SKE), which is subsidiary company of JAPEX, improved and increased their drilling crew for three (3) rigs operation by 2nd quarter in fiscal year 2007.
Additionally, the feasibility study of introduction of the foreign drilling crew was started from 2006. It was the legal reconfirmation of introduction of the foreign drilling crew at domestic operation site. And also, various action items were extracted and made action plans to achieve the safe operation and the operational objectives under the Mine Safety Law and JAPEX safety rules, as it was first trial for JAPEX to dispatch the foreign drilling crew at domestic operation site.
After this study and its confirmation, it was decided to dispatch the Filipino drilling crew for three (3) wells workover Operation in JAPEX Offshore (JPO) IWAFUNE-Oki platform. The Operation was conducted from June through August of 2007.
This paper outlines preparation work for introduction of foreign drilling crew, implementation structure for workover operation and safety management during operation etc.View full abstractDownload PDF (3682K) -

JOURNAL FREE ACCESSEnvironmental problems get into the news in recent years, and environmental measures and reduction of the negative environment impact in company activities are required. JAPEX considers environment problems as one of the top priority issues and working from various angle to environment. JAPEX is working in order to achieve reduction of the negative environment impact by introducing ISO 14001, Environment Management System.
Environment measures in drilling operation also increase in importance and the implementation of drilling operation in an environmentally friendly way is necessary and indispensable. Due to the high oil price in the last few years, profitability of the existing fields are improved and the redevelopment works increase by reviewing and re-interpreting of the existing production well data and field data. Especially, these works in old field which are existed nearby residential area are required special considerations. The redevelopment works in theses area required reduction on the noise and of other negative environment impact.View full abstractDownload PDF (7836K) -

JOURNAL FREE ACCESSThe Piper Alpha disaster occurred in the UK sector of the North Sea in 1988. The disaster shook the oil industry into recognizing the importance of safety management systems. Three years later, in 1991 JDC commenced operations in Australia and realized that a safety management system would become an important part of offshore oil and gas operations. JDC implemented its HSE Management Plan (MP) across the company in 1994, upgraded it to HSE Management System (MS) in 1998, and, most recently, modified it to the HSQE MS in August 2007. The main additions revolved around “Q”, namely quality, and meeting the requirements of ISO 9001.View full abstractDownload PDF (2773K) -

JOURNAL FREE ACCESSThe various human resource development programs with a focus on fieldwork for earth resources engineering have been carried out in Kyushu University. The traditional internship subject of Kyushu University, that began over 90 years ago, brings in a great educational effect for human resource development. More than 2000 students took the internship program and more than 100 students went abroad to accomplish the internship subject. However, Kyushu University cannot carry out the internship subject alone. Kyushu University is supported by a lot of companies related to earth resources and energy. Although the internship subject requires great care by both teachers and companies, it is necessary for human resource development to bring up “Earth system engineers in the 21st century”.View full abstractDownload PDF (2739K) -

JOURNAL FREE ACCESSIn recent years, oil and gas prices have been soaring due to perceived supply-demand imbalance and inflow of money from speculative investors. In order to meet the increasing demand, oil and gas E&P companies have increased their activities significantly in deep water and remote area exploration, in development of new fields and unconventional hydrocarbon and in enhancement of production and recovery rate.
According to the result of one of the surveys conducted last year, surprisingly, it was found that one of the most urgent problems E&P companies were facing was “shortage of skilled workers”, that surpassed easily expected answers such as “shortage of equipment and materials”, “increased cost” and “difficulties to secure new concessions”.
Schlumberger is one of the major integrated oil field service companies that operates in more than 80 countries with 80,000 employees and we are not exempt from the skill shortage problems, either. Of course, the degree of the problem and adequate solution to the problem are different for each company or organization but in this paper, I would like to demonstrate how Schlumberger sees the skill shortage problems and how we are addressing the issues, as an example.View full abstractDownload PDF (3164K)

JOURNAL FREE ACCESSFission-track dating using both internal and external surfaces of zircons was carried out for ten core samples from the Miocene formations in the Ayukawa-Yurihara district, Akita Prefecture. These samples were collected from the Yashiozawakawa, Nishikurosawa and Onnagawa Formations of eight wells drilled for the petroleum exploration in this area.
After the detail examination for grain ages of each sample using histogram, age spectrum and radial plot, fission-track ages are interpretated. The results are summarized as follows.
1) Although external fission-track age (20.1 ± 1.3Ma) of andesite in the upper part of the Yashiozawakawa Formation shows the eruption age with some possibility of rejuvenation, internal fission-track age (16.4 ± 0.6Ma) shows the thermal event which probably corresponds to the start of the “graben-fill basalt” activity.
2) The most reliable internal fission-track age (12.2 ± 0.4Ma) of acidic tuff in the Nishikurosawa Formation is in harmony with the biostratigraphic age of this formation. The external fission-track age (16.6 ± 0.8Ma) indicates that the provenance of zircons is probably the Hatamura Formation.
3) The most reliable fission-track age of tuffs between the O-1 and O-2 benthonic foraminiferal assemblages, 8.6 ± 0.4 Ma of the Ayukawa-kita well, is consistent with Sr isotopic age (about 9Ma) of the O-2 assemblage. The age of the O-1 assemblage is estimated 8.2 Ma based on K-Ar ages of the overlying Fukuyama andesite. Therefore, the O-1 assemblage is correlated with “Blue zone” in Niigata Prefecture, and has a possibility of regional correlation marker.
4) This study indicates that the fission-track dating using both surfaces and more than one samples of the same horizon is a valuable method for the use of few and expensive cores.View full abstractDownload PDF (4860K)
