... a typical production lifecycle, every oil and gas field faces unique flow assurance challenges. Among all, sand production poses one of the most severe flow assurance risks. Large sand particles tend to settle in the pipeline forming pockets of sand beds while the small particles are carried away with fluid...

... (reservoir - bottom hole - wellbore). In view of the key problems of sand production management, the concept of integration in the sand control completion project is applied to carry out the research on the sand particle change law in the whole flow area from the reservoir to the wellbore. A fractal...

... is the most commonly employed method for lost circulation control in engineering. This paper compares and selects the densest packing model, determining the optimal model for research on lost circulation control. Furthermore, simulations of the densest packing of plugging material particles within fractures...

.... To study detachment of fines during different stages of rock drying, we modelled forces and torques exerting the attached clay particles by the by-passing CO 2 flow. It allows formulating the mobilisation criteria for attached clays. The main phenomena observed encompass intensive viscous fingering, rock...

... Abstract Low permeability, naturally fractured reservoirs such as coal seam gas (CSG, coalbed methane or CBM) and shale gas reservoirs generally require well stimulation to achieve economic production rates. Coupling hydraulic fracturing and micro-proppant or graded particle injections (GPI...

... is accelerated ( Hewlett and Liska, 2019 ). This type of cement has a smaller particle size and hence higher surface area which improves its reactivity. The water to cement ratio can be increased to 56% to achieve the standard performance of pumpability and early strength. It also has substantially higher C3A...
