...Brendan J. Smith; Stuart Buckingham; Daniel F. Touzel; Abigail M. Corbett; Charles Tavner Summary With atmospheric methane concentrations rising and spurring increased social concern, there is a renewed focus in the oil and gas industry on methane emission monitoring and control. In 2019, a methane...

... is 1100×10 4 g/mol. The pipeline friction results show that the drag reducer has good friction reduction and salt resistance. When the concentration in clean water is 0.06%, the maximum friction reduction rate is 71.1%. When the salinity is 5×10 4 mg/L, the calcium ion concentration is 2000 mg/L...

... also performed to understand the demulsification process and mechanism. Based on the response surface method (RSM), central composite design (CCD) was used to develop the statistical model of demulsification efficiency by considering the four most influencing factors—demulsifier concentration, water...

... concentration. For example, despite the fact that the asphaltene percent of the crude oil from Algeria’s Hassi-Messaoud oil field is just 0.06 wt%, significant AD has been documented in the production tubing ( Haskett and Tartera 1965 ). The Yen model is one of the first approaches for describing...
