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 ...

The selection of well pattern system is not only the key content in process oilfield development, but also core problem design development. It basis for effective utilization tight reservoir technology. Through scientific analysis geological structure and dynamic characteristics Yang H oilfield, can be reasonably optimized development Chinese vigorous. Starting from oil gas field this paper ana...

The usages of the composite materials range from simple household to light-to-heavy industrial purposes including oilfield applications. The objective of this study is to evaluate current and potential uses of composite materials for the petroleum industry. This article gathered all the available composite materials that are normally used specially in oilfield and surface pipeline applications....

Greenhouse gas (GHG) emissions from oil and gas systems are an important component of the GHG emission inventory. To assess the carbon emissions from oilfield-produced water under atmospheric conditions correctly, in situ detection and simulation experiments were developed to study the natural release of GHG into the atmosphere in the Shengli Oilfield, the second largest oilfield in China. The ...

The oil company holds the investment opportunity to develop a delineated oilfield. The investment plan must be presented until a specific date or the oilfield rights return to the government. The firm considers a set of mutually exclusive alternatives of scale to exploit the oilfield. Larger scale means faster exploitation – increasing the present value of revenues, but also higher investment c...

Wellbore instability is one of the major problems that hamper the drilling speed in Halfaya Oilfield. Comprehensive analysis of geological and engineering data indicates that Halfaya Oilfield features fractured shale in the Nahr Umr Formation. Complex accidents such as wellbore collapse and sticking emerged frequently in this formation. Tests and theoretical analysis revealed that wellbore inst...

After more than ten years of water injection development, the cut in main block oilfield B has increased rapidly and production decreased significantly. In view rapid rise comprehensive current oilfield, it is necessary to carry out research on development law reasonable boundary various adjustment indexes, so as clarify different stages The status index change under oil rates provide an accura...

Going through the development more than forty years, the overall water-cut to Daqing Oilfield has almost reached 90%. But there is still considerable residual oil in the place. Reservoir engineers want to know the residual oil spatial distribution and how to dig it. This requires large-scale reservoir simulation within limited time. Enlarged scale and highly expected efficiency need higher tech...
