Scale inhibitor squeeze treatments have been applied for many decades to control inorganic scales in onshore/offshore production wells. A series of coreflood tests were conducted with reservoir carbonate cores, This paper presents field results and laboratory evaluation data for the application of corrosion inhibitors via the squeeze process.

The process of scale inhibitor squeeze treatments is well known within the hydrocarbon extraction industry. These treatments have been applied for many decades to control inorganic scales in onshore/offshore production wells. This paper presents field results and laboratory evaluation data for the application of corrosion inhibitors via the squeeze process.

A series of coreflood tests were conducted with reservoir carbonate cores applying the treatment chemicals via matrix flow and also tests were conducted where the treatment chemicals were applied via fracture/matrix flow regime. Permeability measurements to field crude and synthetic brine were conducted prior to and following the corrosion inhibitor treatment package being applied.

Results from the coreflood studies showed that wettability alteration (increased water wetness) was observed within matrix flow only tests but in the fracture/matrix flow tests this damage was not observed. As the treatments in the example field were shallow penetration treatments it is clear that the fracture/matrix flow tests were reflecting the true application. The deeper penetration of chemical into the reservoir which was hoped would extend the squeeze life clearly shows formation damage so further work on the corrosion inhibitor formulation is required to reduce the wettability effects reported.

A forty foot well annulus simulator is used to determine the flow and fate of the applied chemical inhibitors for typical backside batch and flush application in a packerless completion. The delivery depends upon both chemical parameters such as density, viscosity, and surface tension as well as flush parameters including volume and rate.
