... can accurately estimate the wax breaking force (WBF) and the wax removal efficiency (WRE) under various pigging conditions, according to the experimental results and published data. In addition, the indoor pigging experiments revealed for the first time that a higher pigging speed could increase...

.... For horizontal shale gas wells, it is often necessary to clean the oil-based mud (OBM) before pumping cement slurry to ensure sufficient contact and bonding of cement slurry to casing and formation. Therefore, the removal efficiency of OBM determines the cementation quality of cement slurry with casing...

... thickness, and the shear strength of wax sample on the wax breaking force and the wax removal efficiency are investigated experimentally. It is found that the wax breaking force decreases and the wax removal efficiency increases when the coating hardness is increased. On the basis of the analysis...

... maghemite nanoparticles with high oil removal efficiency can reduce produced water treatment costs and promote this technology as an economically feasible option within the industry. Nanoparticles were manufactured after three different coprecipitation techniques ( Wu and Gao 2012 ; Nazari et al. 2014...

...Renzhou Meng; Chengwen Wang; Zhonghou Shen Summary In this study, an oil‐in‐water nanoemulsion for the effective removal of an oil‐based drilling fluid has been developed by means of the phase‐inversion concentration method. The influence of four factors on the droplet size and removal efficiency...
