Examples The linear relationship...

... on these types of completions require leaving the drilling high density oil-based mud (OBM) behind the completion. This leads to higher formation damage due to OBM-induced solids and thicker wellbore filter cakes. The OBM is then managed by well stimulation treatments that further squeeze it into the formation...

... Abstract Fines migration is a recognized as one source of formation damage in oil and gas production wells. A newly fine stabilizers chemical was developed and applied to prolong oil well productivity by adhering the migrating fines to the pore surfaces and reducing the tendency...

... productivity indicators, it became clear that formation damage was occurring in several wells with varying degrees of severity based on the performance of the reservoir layer being produced. Various formation damage mechanisms were assessed (scale, wax, asphaltenes, drilling & completion damage, fines...

... cause of formation damage in this well, which is a mechanical mechanism caused by fines migration. Treatment with a fine stabilizer may be chosen to prolong the productivity of the well. This workflow can be used as a practical guide for determining the source of formation damage via integrated...

... Abstract The objective of this paper is to evaluate the formation damage mechanisms on carbonate porous media due to the effect of solids (high-density Mn 3 O 4 and BaSO 4 weighting materials) and other particles dispersed in workover fluids. Barite (BaSO 4 ) and Manganese Tetroxide (Mn 3 O 4...
