Damage Removal

APPLICATIONS » “Formation damage” is a catch-all term used to describe detrimental changes in the flow capacity of a reservoir rock and ultimately the productivity (or injectivity) of a well. It is the main reason many oil and gas wells produce at rates that fall far-short of their theoretical capabilities. It affects literally hundreds of thousands of wells around the world and formation damage, of one form or another, is probably the biggest cause of sub-optimal production today. The same phenomenon also impairs injection and disposal wells, limiting the efficiency of pressure maintenance schemes and increasing operating costs.

The flow impairment that defines formation damage is often expressed as some form of “skin”, a term that encompasses many different mechanisms for reduced productivity. However, formation damage represents a specific type of “skin” and arises when the original permeability of the producing formation is unfavorably altered, adjacent to the well. It is caused by many factors and can occur during the drilling process, or at any time thereafter, throughout the entire life of the well.
