The SD107 gel system developed has good oil–water phase selective gelation and blocking properties. static gel-forming experiment results showed that the water shutoff formulated with oilfield reinjection (oil content < 0.05%) a viscosity of 200 mPa·s after gelation, plugging produced fluid ? 20.0%) had 26 gelation. Results core physical simulation indicated enhanced recovery rate was highes...

The largest ultra?deep (>7000 m) strike?slip fault?controlled oilfield was found in the tight Ordovician carbonates Tarim Basin. Because oil production wells Fuman Oilfield generally have bottom water, a reasonable design is of significant importance for extending water?free recovery period and improving recovery. However, there no economical effective quantitative method to determine capaci...

Past research has suggested that during the calving period, caribou (Rangifer tarandus) in Arctic Alaska generally avoid areas within 1 km of oilfield roads with traffic. However, avoidance is not absolute, and caribou may habituate to infrastructure (e.g., buildings, roads, well pads) and human activity. We conducted road-based surveys of caribou in oilfields on Alaska’s Arctic Coastal Plain d...

Geothermal energy is a clean, green renewable resource, which can be utilized for power generation, heating, cooling, and could effectively replace oil, gas, and coal. In recent years, oil companies have put more efforts into exploiting and utilizing geothermal energy with advanced technologies for heat-tracing oil gathering and transportation, central heating, etc., which has not only reduced ...

Subsidence in river deltas is a complex process that has both natural and human causes. Increasing human activities like aquaculture and petroleum extraction are affecting the Yellow River delta, and one consequence is subsidence. The purpose of this study is to measure the surface displacements in the Yellow River delta region and to investigate the corresponding subsidence source. In this pap...

With the introduction of nanotechnology, energy industries envisage a potential revolutionary change in the field of exploration, development and production. Research by universities into such areas as nanosensors, nanomarkers and nanobots to provide valuable data regarding the reservoir are of great focus due to their large potential return on investment, but have yet to yield substantive prod...

A Oilfield is Fluvial Facies Low Permeable Reservoir, main layer bend distributary channel sand body deposition, In order to better understand the distribution of single and remaining oil in reservoir, inspection well coring tracer tests have been carried out successively same area oilfield, based on these data, it found that, actual very different from original description both vertical plane....

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...

The fundamentals of scaling during waterflooding an oilfield are presented. Mineral precipitation is described using both the kinetics approach, with corresponding equations given, and thermodynamic models’ theoretical foundation discussed—mainly specific ion interaction Pitzer models. This paper focuses on process mixing incompatible waters water injection production from oilfield, as this was...
