説明

<p>A wide variety of human resources training programs have been designed to promote globalizations in oil and gas industry. Among them, studying abroad has improved technical and professional skills, international communication skills and understanding of cultural diversity with strong leadership. It also plays an important role for both employees and organizations especially in developing global networks with multinational major and independent operating companies. It can be said that the global networks would promote competitiveness in international projects.</p><p>This article introduces my own experiences when joining the Ph.D. program in reservoir geophysics at the University of Calgary, from the viewpoint of international student research associate. The graduate study was completely involved with seamless relationships between university and industry. The associated research consortium has been dedicated to providing integrated solutions derived from geophysics, geology, and engineering. For instance, one of the integrated solutions is aimed at production and reservoir monitoring of foamy oil solution gas drive, which is referred to as cold production. Time-lapse seismic monitoring of high-porosity channels called wormholes is a key problem for drilling optimization in cold production process especially for CHOPS.</p><p>In general, it is difficult to monitor the development of wormholes by using time-lapse seismic data, due to differences in resolution. A new approach in seismic monitoring finally yielded porosity maps of wormholes including interpretations of fluid flow orientation in the Plover Lake field, which had been operated by Nexen in Saskatchewan, Canada. Rock physics modeling successfully converted geophysical elastic parameters into porosity which is one of the key parameters in reservoir engineering.</p><p>I had an opportunity to meet the members of the research consortium for business in Calgary within five years after graduation. It worked for successfully sharing the global network with my co-workers in Japan.</p>
