... fluids, a different particle size selection method was found to be more useful to prevent reservoir formation damage. This method involves selecting particles that are resistant towards shear-degradation and with a D90 particle size ⪞3/2 the pore size of the formation. By analyzing fluid loss regression...

In this paper, a new low-damage drilling...

...Xiaodong Han; Liguo Zhong; Yigang Liu; Tao Fang; Cunliang Chen Fine migration is always considered as one of the major mechanisms that are responsible for formation damage. The unwanted reduction of reservoir permeability would result in the decline of water injection and consequent oil production...

... of the medium, and more interestingly on the hydraulic tortuosity as a criterion for changes in preferential flow path. As will be shown, the developed numerical method is able to successfully capture major retention mechanisms responsible for fines migration associated formation damage including external cake...

... crushed zone formation damage Formation damage has always been a major challenge in several branches of the petroleum industry such as reservoir engineering and production technology [ 1 , 2 ], particularly during drilling, completion, production, and workover operations [ 3 – 5 ]. It usually...

...Dujie Zhang; Yili Kang; Lijun You; Jiaxue Li Ultradeep fractured tight sandstone gas reservoir is easy to suffer from severe formation damage during the drill-in process, yet few papers have been published on the corresponding formation damage mechanisms. This paper focuses on a typical ultradeep...
