Polymer Technologies  

Water Shut Off:

Designs and implementation target influx of water production overriding the target production interval through coning or channeling due to vugs, natural fractures, or permeability contrast. Polyacrylamide and x-linker injected into reservoir under frac gradient targeting zones that contribute large water volumes. The chemistry is hydrophilic and therefore bonds to the water-saturated portion of the reservoir. Gel Forms under temperature and pressure variables blocking water and modifying drainage pattern to the wellbore in favor of increased oil production. Typical results offer a 90% or more reduction in water and a 50% or more increase in oil production after treatment. Additional benefits and economic advantages can be realized through reduced expenses related to high water production volumes, such as electricity and chemical costs.

Casing Leaks and Annular Gel Systems for MIT/H5:

Low MW polymers are advantageous in treating tight or pinhole casing leaks where cement cannot penetrate or hold. The polymer can set up as a ringing gel after successfully penetrating the offending area. In addition, there is no need for permanent mechanical “solutions” (such as liners) that restrict flow and no drill out necessary with these applications making them much more cost-effective than other chemistries used for this application.

Conformance:

Design and implementation target inefficient flood patterns to improve oil production by redirecting injection fluid to a tighter, unswept portion of the reservoir. Conformance treatments address high-permeability streaks known as thief zones by blocking these areas deep into the reservoir, thus forcing the injection fluid around the gel block into tighter, oil-saturated rock. This treatment results in the mobilization of bypassed oil to the offset production wells, often resulting in significantly increased reserve recovery.

Vertical Profile Modification:

Design and implementation target inefficient vertical injection profile. In cases where multiple zones are being flooded from a single injection well, the vertical profile will favor one or two intervals with 70% or greater volume of the total daily barrels injected, creating a significant inefficiency in the flood pattern. Vertical Profile Modification Treatments address injection profile inefficiencies by directing injection fluids more proportionally in situations where multiple zones are open, thus increasing oil production.
