The Baker Hughes, a GE company (BHGE) MARCIT-CT™ treatment improves reservoir conformance by preferentially blocking high-flow pathways such as naturally-occurring fractures or other secondary porosity features. The result is improved production from the less swept portions of the reservoir. MARCIT-CT treatments are ideal for improving reservoir fluid conformance in injection wells as well as producing wells.

Producing from naturally fractured reservoirs can be highly profitable when fractures are in good contact with oil. But when fractures extend into an underlying aquifer and create a path for water flow, excessive water production can drive up lifting and handling costs. A MARCIT-CT gel treatment applied to a producing well

can reduce water production by reducing the flow through larger fractures. When injected, the gel follows the path of least resistance, directly into the fracture network. When water flow is reduced oil production can increase, as greater drawdown can be applied to the oil saturated portion of the reservoir.

In waterfloods or EOR floods, poor reservoir conformance can result in a very inefficient flood and waste of expensive EOR fluids such as CO2. Often, poor reservoir conformance results in rapid breakthrough of injection fluids directly into the producers. The MARCIT-CT injection well process has proven to dramatically reduce breakthrough and improve the economics of treated patterns.
