Gel-Tec specializes in Marathon's MARCITsm gel systems (Marathon Conformance Improvement Technology). This robust gel system is designed to reduce or eliminate channeling in both matrix and fractures with temperatures as high as 255° F. The advantages of the MARCITsm gel are as follows:
- Gels can be mixed with most oilfield brines
- It is insensitive to hydrogen sulfide
- Can be used in a pH range of 3.3 to 12.5
- Has a controllable rate of gelation
MARA-SEALsm is also a Marathon technology designed for total water or gas shut-off. This gel system is comprised of a low molecular weight polymer which readily invades the reservoir matrix. Many times it can be substituted for a cement squeeze.
UNOGELSM gel is primarily used for gas wells and high temperature applications that are in excess of 220° F. This organically cross-linked system was developed to provide stable gels with sufficient working time to allow their placement in hostile environments.
