Geothermal Project Experience
Since the 1950s, Halliburton has been a full-service leader in geothermal technology and processes
For decades, Halliburton has been involved in significant geothermal projects around the world—in countries including the U.S., the Philippines, Indonesia, Japan, Australia, New Zealand, Germany, Denmark, Sweden, Mexico, Costa Rica and Kenya. Available to producers worldwide, Halliburton's technology, products and services address every aspect of geothermal: subsurface assessment, drilling, cementing, non-damaging drilling fluids, logging, real-time monitoring and control, completions, stimulation and project management. A provider of unparalleled expertise, services and breakthrough technologies since the beginning, Halliburton continues to be the industry leader in meeting today's unique geothermal challenges.
At this time we are also involved in the planning of geothermal projects, both traditional and EGS (enhanced geothermal systems), in many parts of the world—some of which have no, or little, geothermal energy activity.
Halliburton's Geothermal Project History
While many companies provide services to geothermal organizations, few have the depth, breadth and experience that Halliburton's 50+ years of geothermal history bring to any given project. Nor do they have our diverse portfolio of industry firsts, technologies and processes, and "top to bottom" case studies.
|Reverse Foamed Thermalock™ Cement—Southern California, U.S.
A West Coast geothermal customer had experienced severe losses during the drilling stage of a well. Because of lost circulation problems encountered at various depths, several lost circulations plugs were set to cure the problem. In addition, present CO2 posed additional problems. To overcome this situation, Halliburton proposed foamed Thermalock Cement, pumped in reverse circulation fashion.
|Dual Injection Job Using ZoneSeal® Process—Western U.S.
In this well, CO2 gas breakthrough depth was estimated at about 1,500 ft. where an upper "thief zone" (a zone where significant loss of pumped-in fluids occurs) was located. Halliburton's ZoneSeal Isolation Process involving a dual injection method was chosen to address the issue of the significant CO2 gas breakthrough in the wellbore annulus.
|Electromagnetic (EMT) MWD System—Southeastern California
While geothermal wells have been drilled in California's Coso field for over 22 years, lost circulation has always been one of the major issues with successfully drilling these wells—often requiring more than 10 lost circulation plugs per well to regain returns. To solve this problem, Halliburton's Electromagnetic MWD/LWD System, which does not rely on a column of fluid to transmit data to surface, was successfully employed.
