Hydraulic fracturing utilizes pressurized liquid typically consisting of water, proppants, and a multitude chemical additives, in order to fracture petroliferous strata extract natural gas oil. In this process, vast amount wastewater is produced. This water heavily contaminated, which renders it unusable outside direct reuse, without extensive treatment being performed. Typically, various sophi...

Tank bottoms from a Williston Basin oilfield were applied to test plots in which crops were subsequently planted. Naturally occurring microbes reduced the 6% total petroleum hydrocarbon (TPH) concentration to 3.8% in a few months (a 37% reduction), but reduced it no further, possibly due to an insufficient amount of nitrogen or water or both. For the first three years of the study, the 6% TPH t...

A coagulation treatment is a separation technology widely used in industries as pre-treatment step to remove the dissolved organic matter wastewater. However, type of coagulant, optimized dose, and cost associated with various commercially employed coagulants must be investigated for oil gas produced water. In this study, five coagulants—ferric chloride, aluminum potassium sulphate, chitosan, s...

In the process of oilfield development, water injection is a very important work content, and reservoir exploitation quality, efficiency, are closely related. Oilfield technology has been widely applied popularized, but in specific application, it will also have some influence on oilfield, such as causing oil layer blockage. The author focus application well injection, analyze related reasons f...

Produced waters (PWs) are oilfield waste streams rich in minerals and hydrocarbons whose production rate is largely increased last decades following the corresponding increase of energy demand. The high salinity level PWs inhibits adoption cheap biological treatments. Also, desalination techniques based on osmotic membranes would require severe pre-treatments. As an alternative, Reverse Electro...

Oil field is a very important non-renewable resource in China, which plays role economic strategy. In the process of oil development, water flooding technology can effectively improve production quality, provide strong technical support for our exploitation, and help to promote sustainable development enterprises. However, there are many influencing factors exploitation oilfield, so workers nee...

Design space exploration (DSE) is a common yet complex workflow in oilfield asset development. The “design” of an oilfield refers to a set of decisions about aspects ranging from well locations and number to facility sizing for optimum production. Evaluation of alternate designs – based extensively on reservoir simulations – corresponds to the evaluation of alternate development scenarios in fa...
