With the demand of customers satisfied one after another, the company has expanded its market share. It makes the technological design at the top level, establishes a perfect and opening system for technological development and conversion of research results, brings the projects under management over the whole period, highlights the leading technological talents, and perfect the examination and stimulation mechanism for encouragement of creation and application of technological results. Therefore, with the breakthroughs made in technological creation, the company has remarkably improved its capability for oil and gas discovery. Based on the statistics, BGP has owned “two technological edges” of geophysical software and equipment and made a significant progress in the key three technologies for oil reservoir, deepwater areas and complicated regions. A total of 234 items have been cumulatively applied for patents, of which 133 item were approved to have patents. The application rate of technological results exceeded 80 percent. The developed GeoEast --- large-scale processing and interpretation integration software --- and ES109 large-scale seismic instrument filled up the domestic blank in this field, changing the situation that the domestic geophysical sector depended on import of core software and equipment over a long period of time. As a result, the company has significantly improved its international industrial position and the influence of brand-name products.

A New Method for Comprehensive Assessment of Oilfield Development Project Li Bin and Gao Zhengyuan 2013, 32(6): 35-38.  DOI: 10.3969/j.issn.1002-302x.2013.06.010 Abstract ( )   PDF (5151KB) ( )   Used extensively in various sectors, comprehensive assessment is gradually developed into a mature assessment system. However, these methods are commonly featured for complicated calculation. It is proposed to establish a target differential degree method for the purpose to solve the comprehensive assessment issues of oilfield development projects. The basic principle of this method is to design an optimum target and then calculate the differential degree between the appraised target and the optimum target. The smaller the differential degree is, the better the appraised target is. The calculation case of oilfield development project shows that this method is clear in its theoretical basis, simple and workable for calculation as well as scientific, reliable and applicable as a new effective method for comprehensive assessment.
