TL;DR: In this paper, the main formation damage mechanisms during shale gas reservoir exploitation, including the physical and chemical damage, are discussed in detail, and the systematic evaluation method of formation damage, heat treatment and working fluid loss control, as three further research directions for formation damage control and removal are proposed for the efficient development of shale gas reservoirs.

TL;DR: In this paper, a new mathematical model was developed to characterize the performance of drill-in fluid-loss control by use of lost-circulation material (LCM) during the drilling in process of fractured tight reservoirs.

TL;DR: Wang et al. as discussed by the authors conducted laboratory experiments and developed a mathematical model to evaluate the formation damage degree and determine the damage range, and established a formation damage pattern to analyze the mechanism and process of formation damage induced by working fluid loss.

TL;DR: In this article, a stochastic micro-scale model for size-exclusion particulate-suspension transport in fractured media is proposed to account for the fracture network connectivity and its subsequent evolution due to particle capture by the introduction of percolation theory.

TL;DR: Wang et al. as mentioned in this paper developed the temporary sealing technology and proposed its key indexes to control drill-in loss in fractured reservoir, including maximum plugging pressure, total loss volume before sealing and permeability recovery rate.
