Well Integrity

With the increasing number of legacy wells and its usage beyond the safe lifecycle, the well integrity problem requires urgent attention. We, at GPS, have been working in this particular field for a long time and have mastered the art of dealing with problem of well integrity. We have spent years in developing customized solutions for well integrity in wells for different applications such as high-temperature, Carbon Capture Utilization and Sequestration (CCUS). These solutions include geopolymers for cementing, novel materials, and computational models.

Our expertize in Well Integrity includes design, develop, and test of techniques and technologies for solving well integrity issues.

CURRENT PROJECT



U.S. Department of Energy (DOE) awarded $200,000 in funding to GPS for a new Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) geothermal project

GPS will investigate and develop geopolymer grouts enhanced by nano-material fillers to be used in the completion of subsurface wells for geothermal/ground source heat pumps.

Grout is a cementitious material mixed with water, with or without aggregate, in a certain proportion to produce a pourable consistency mixture without having segregation of the constituent elements. Geopolymer based cement usage as a binder in grout material has a positive impact on the environment. The amount of the carbon dioxide released during the manufacture of cement due to the calcination of limestone and combustion of fossil fuel is in the order of one ton for every ton of ordinary Portland cement (OPC) produced. The application of geopolymer binder as an eco-friendly subsitute for well completion in geothermal wells is an attractive avenue. Admixtures to increase flowability and setting time will be necessary to be applied.

The aim of this project is to develop a potential geopolymer paste as an alternative of grouting material by fulfilling the material grout requirement such as should be able to flow through the narrow gaps and have adequate compressive strength and good durability.

These grouts show promise for reducing well completion costs as well as overall project costs for installation and operation. Ultimately, the project will help reduce the carbon footprint of residential, commercial, and industrial buildings.

As per GTO Director Susan Hamm, "Small businesses like Greenpath Systems are instrumental in developing creative new geothermal technologies that will advance market-oriented solutions to the global climate emergency and propel our nation to achieve net-zero carbon emissions by 2050.”
