In today’s society, with the continuous growth of energy demand, Bohai Oilfield, as an important offshore oil resource base in China, is facing increasingly severe challenges while contributing to national security. order improve quality water injection oilfield and gradually achieve efficient stable production, Oilfield has launched a well pressure optimization project, focusing on improving e...

A comparative analysis of the physico-chemical parameters of treated oilfield formation water and that of a freshwater stream with no previous history of pollution from oil exploration activities was determined. The environmental impact resulting from the discharge of treated oilfield formation water into freshwater samples collected from this stream with no previous history of pollution from o...

In the process of water injection development in low-permeability and extra-low-permeability oil fields, absorption capacity wells continues to decline, number under-injection is increasing, which affects effect fields. this paper, we take X oilfield as an example carry out single-well pressurized tests determine range reasonable pressure for geological conditions suitable injection. Through pr...

Thin reservoirs prediction method such as spectral inversion has drawn considerable attention in recent years. In order to avoid extracting wavelets within the whole field area purposeless and make filtered data preferable fidelity well signal-to-noise ratio, an effective structural constrained thin reservoir description which combines wide-band Ricker wavelet filtering technology been proposed...

Two irregular coccoid methanogens designated SEBR 4845T and FR1T were isolated from an oilfield in Alsace, France. Strain SEBR 4845T (T = type strain) is a hydrogenotrophic halotolerant methanogen, which grows optimally at 5% NaCI (w/v) and tolerates up to 12% NaCI. It does not use methylated compounds and therefore cannot be ascribed to any of the known genera of the halophilic methylotrophic ...
