TRABITS GROUP NEWS
Trabits Group's FlexCem® is now a registered trademark
Trabits Group has received Trademark registration for the FlexCem® name. FlexCem® cements are manufactured using a patented technology where cement clinker and proprietary zeolite are interground in specific rations. Intergrinding produces a bimodal particle size distribution between the harder clinker and the softer zeolite resulting in increased strength properties. FlexCem® cements are Earth Friendly through the reduction of greenhouse gas emissions during manufacture.
FlexCem® development featured as an "EERE Success Story" by the US Department of Energy
The web site for the US-DOE Office of Energy Efficiency and Renewable Energy (EERE) features Trabits Group's FlexCem® as one of their Success Stories - Geothermal Wells: Advancing the Technology .
"...With assistance from GTO, Trabits Group, LLC has successfully developed a cement that performs strongly in harsh geothermal conditions and is easy to use. Containing zeolites a naturally occurring mineral that can be readily dehydrated and rehydrated this cement reduces the complexity and cost of well cementing, which will help enable the widespread development of geothermal energy in the United States...."

Trabits Group FlexCem® development featured in the June, 2016 issue of Global Cement Magazine
In a Global Cement Magazine article titled "Development of a lower cost, high performance, lightweight well cement" (June, 2016, page 29) Trabits Group president George Trabits outlines the development of the product now being brought to market as FlexCem®. Mr. Trabits describes the characteristics of the mineral zeolite, and the years-long process of development and testing of zeolite-containing cements by Trabits Group and partners including the US Department of Energy.

Trabits Group participated in the DOE Geothermal Technologies Office 2015 Peer Review Program
Trabits Group was pleased to participate in the Department of Energy (DOE) Geothermal Technologies Office 2015 Peer Review Program. The Peer Review program was held in Westminster, Colorado May 11 - 14, 2015. DOE-funded projects are evaluated for accomplishments, results, and progress of their geothermal research, and scientific approach by scientific experts from the National Labs. At the 2015 Peer Review Program thirty-three projects were presented for review.
Scientific panel comments on the Trabits Group zeolite-containing / interground variable density cement included:
- Reviewer 25041
- "This project develops a novel, zeolite-based light weight, high temperature, and high pressure geothermal cement."
- Reviewer 23537
- "It appears that the required criteria were met via this zeolite compound and that the Quality of this work and the Productivity standards were all met to a high degree."
- Reviewer 23478
- "The cements produced appear to be relatively easy to manufacture, they have far fewer additives or other chemicals, and are not complex. This probably means that they can be obtained easily for use in remote sites and that they can be emplaced without sophisticated equipment or procedures."
- Reviewer 23478
- "Use of clinker to modulate the zeolite grinding process in cement preparation is innovative."
- Brookhaven National Laboratory
- "The Trabits Group solution is beautiful because it is simple."
The Trabits Group Geothermal Well Cement Development project has been chosen as the current featured project by the US Department of Energy, Geothermal Technologies Office
The Trabits Group project is displayed on the home page of the GTO projects listing database.
The United States Department of Energy, Geothermal Technologies Office has chosen the Trabits Group project as the featured project for display on their projects database web site. The project was chosen from among a nationwide list of over two hundred currently funded projects listed in the database.
Funded projects address a wide variety of challenges in geothermal development throughout the United States. Go here to explore the database listings.
Geothermal Well Cement Development
Trabits Group has developed a zeolite-containing high temperature/high pressure geothermal well cement under a $2,154,238 grant from the U.S. Department of Energy. Trabits Group has also developed a lightweight zeolite-containing well cement using a patented method for intergrinding cement clinker and zeolite. Trabits Group has completed a full-scale production run of the lightweight interground composite well cement at a western U.S. cement plant.

UAF Installs Advanced Well Cement Testing Equipment in Alaska
Press release 8/24/12 by Trabits Group
Pictured are left Dr. Santanu Khataniar, center Dr. Abhijit Dandekar and right George Trabits. Equipment is Chandler 8340 Consistometer and Chandler 1910 Curing Chamber.
Petroleum engineering students at the University of Alaska Fairbanks will now enjoy access to cutting edge well cement testing technology, thanks in part to Trabits Group.
The new equipment, installed this summer at UAF's Petroleum Development Laboratory (PDL) brings to Alaska cement testing technology that previously existed only in the Lower 48, providing not only the ability to conduct cementing research in Alaska but training for Alaska's future oil, gas and geothermal resource workforce. It also plays a key role in promoting and advancing the science of cementing, a crucial component of safe and responsible drilling practices.
The new well cement testing equipment installed at UAF includes:
- High-temperature, high-pressure consistometers to measure cement's thickening time under extreme conditions.
- An ultrasonic cement analyzer (UCA) system that helps to continuously monitor cement composition development trends during the curing process. Testing takes place inside a pressure-and-temperature-controlled curing chamber and is completed without destroying the cement sample.
- A fluid loss cell to measure the loss of water from cement slurry, ensuring cement strength is not compromised when set.
- A six-speed viscometer, which measures viscosity of cement slurries.
"Trabits Group continues to be impressed with the UAF professors and their dedication to training the future petroleum workforce for Alaska," said Trabits Group President George Trabits. "We are fortunate to have partnered with UAF in a proposal to the Department of Energy to develop a high-temperature, high-pressure geothermal well cement. The Trabits Group / UAF proposal was one of four geothermal technologies projects in Alaska selected for funding by DOE and the only geothermal well cement project selected in the U.S."
"We're very excited to welcome the addition of this state-of-the-art equipment to the PDL," said PDL Director Shirish Patil. "Already two of our graduate students have been trained by Halliburton at their Wyoming Training Center to work on this equipment."
The project also supports a member of the research faculty and an undergraduate student assistant who is currently being trained by Baker Hughes in their Bakersfield, Calif., facility.
