Scale Control

As offshore production environments become ever more complex, particularly in deepwater regions, the risks associated with formation damage due to precipitation of inorganic scales may increase to the point that production by conventional waterflooding may cease to be viable. The ability to predict and control such formation damage can thus become critical to project success under such circumstances. The work described in this paper presents how the risk may be managed from early in the CAPEX phase of projects through to the OPEX phase by use of reservoir simulation tools to better understand the scaling potential in a reservoir and the possibilities for effective scale control. This process is illustrated by reference to a number of field examples where specific scaling problems have been identified, and the ability to implement effective scale management has been impacted by detailed fluid flow and brine-mixing calculations.

This study discusses formation damage mechanisms that were caused by commonly used chemical treatments. The chemicals used in these treatments included a scale inhibitor, a biocide-corrosion inhibitor, an in situ gelled acid, a full-strength mud acid, and a mutual solvent. These treatments were designed to remove a known form of formation damage. However, they created new forms of formation damage, which resulted in a significant decline in the performance of the treated wells. Case histories that illustrate the initial and new formation damage mechanisms are explained in detail. Laboratory and field studies that were performed to identify these mechanisms are discussed. Moreover, this paper highlights the remedial actions and field application that resulted in restoring the performance of various wells without affecting the integrity of the formation (both carbonate and sandstone). Finally, recommendations are given to minimize formation damage due to various chemical treatments.
