Successful Treatment in Water Control with Relative Permeability Modifiers for HP/HT Carbonates

Abstract

One of the main problems in the decline of the production of any field is associated with the presence of fractional flow of water and its detrimental effect on the wells. This situation has led to a whole field of study regarding the understanding of this phenomenon, aimed at mitigating this through the application of several technologies and best reservoir management practices. This paper will present the analysis, development and results obtained from the application of a relative permeability modifier (RPM) in a naturally fractured carbonate reservoir under high pressure and temperature conditions (HP / HT). This is in addition to a series of so-called "high potential" interventions, whose production benefits result in a profitable business case applying an optimized shut-in time strategy in high production wells. Finally, a summary with various results of the application of the RPM in different wells will allow broadening the criteria of its application. Although there are cases of success, there will be others in which a better diagnosis must be made to ascertain its effectiveness in the short or medium term, which may be related to the identification of the preferential means of flow in a naturally fractured reservoir, which by its nature, results in a technical-technological challenge, both in its identification and discretization as well as in the field applications.
