REXA
REXA Electraulic Actuator's self-contained design increases uptime, reduces mainte- nance, and improves control for geothermal steam turbines. Maintenance is removed through elimination of the HPU skid, all hydraulic piping, ltration systems, and sampling requirements. REXA’s precise po- sitioning and repeatability improves turbine control, and its rugged construction provides maximum durability in extreme conditions. www.rexa.com
Ecology & Environment, Inc.
A strategic permitting and stakeholder out- reach approach is critical to developing suc- cessful geothermal energy projects. Ecology and Environment, Inc. (E&E) recognizes that getting new projects approved is as much about building relationships, as it is about building infrastructure. They prepare re- quired federal environmental impact state- ments, state or provincial-equivalent impact assessments, and local use permits. E&E knows the issues and challenges associ- ated with geothermal development on both public and private lands. They’ve worked in regions with high potential for utility-scale geothermal energy development and offer clients smart solutions to help them move through the entire project life cycle with
a proactive approach and careful planning that saves both time and money. www.ene.com/markets/geothermal

DRILLING
Hammer Rig Rentals USA, LLC
Hammer Rig Rentals USA, LLC offers exible and convenient drilling rig rentals, used equipment, and tooling sales all over the US. Specializing in micro-piling, limited access, and geothermal drill- ing equipment rental contracts, they also offer lease-to-own options and used equipment sales. www.hammerrigrentals.com
Webco, Inc.
Webco Industries manufactures LaserLine seam- welded nickel alloy, duplex, and stainless steel coiled tubing, including capillary strings for scale and corrosion inhibition in geothermal wells. Tube sizes range from: 0.250 to 1.5 OD, wall thickness from 0.035 to 0.125, and lengths can be up to 12,000 meters or longer. Product speci cations and process requirements can be met by tailoring material grades and customizing to speci cation, including limiting orbital welds. www.webcotube.com
WWT International Drilling Tool Services
WWT Non-Rotating Protectors (NRPS) measur- ably improve drilling and well cleanout opera- tions in geothermal applications by preventing casing wear to preserve casing integrity. Torque and drag are also signi cantly reduced which im- proves drilling performance by reducing rotational and sliding friction. WWT NRPS have been run on numerous geothermal wells all around the globe. www.wwtinternational.com
EDUCATION | R&D
The Geothermal Institute
The Geothermal Institute conducts geothermal energy related research, education, consulting, and training programs. It also provides research and development, testing and laboratory services, and commercial services. The Geothermal Insti- tute is one of the premier geothermal training centers in the world and coordinates the post- graduate geothermal programs for the University of Auckland. The Geothermal Institute convenes the annual NZ Geothermal Workshop, NZ’s long- est running energy conference www.geothermal.auckland.ac.nz
ENGINEERING & EQUIPMENT
A-T Controls
A-T Controls provides solutions for demanding geothermal applications, providing a variety of durable valves for tough environments. The A-T Controls M Series Metal-seat Ball Valve, for example, is designed for use in more challenging services, such as higher temperature and pres- sure projects. It can be used in temperatures of up to 1100°F (593°C). Their V-Series Segment Control Valves range in size from 2" to 16", and support temperatures up to 600°F (315.5°C). A-T Controls’ Power-seal High-performance Butter y Valve comes with a pneumatic, spring-return ac- tuator or double-acting actuator. All A-T Control valves are quickly and easily automated. www.atcontrols.com
Nash, by Gardner Denver
Gardner Denver Nash is an international supplier of gas removal systems for geothermal power plants. Nash has over 110 years of experience designing and manufacturing liquid ring pumps and steam jet ejectors. Since every geothermal resource and every plant site is unique, Nash engineers draw on their wealth of application engineering know-how and product development data, to optimize each system to maximize perfor- mance and prolong the life of each resource. www.GDNash.com
EXPLORATION & SITE ASSESSMENT
ENVIRONMENTAL | ENGINEERING CONSULTANTS
Bell Geospace
Bell Geospace acquires, processes, and interprets airborne full tensor gravity gradiometry data
for resource exploration. By measuring density changes, FTG data can be used to map geologic structure associated with geothermal deposits. www.bellgeo.com
GeothermEx
Since 1973, GeothermEx has been working with geothermal developers, investors, regulators,
and land owners to explore, assess, and develop geothermal resources. Focusing on the subsurface resource, the riskiest element of all geothermal projects, GeothermEx’s team of geoscientists and engineers have participated in hundreds of geo- thermal projects all around the world, including 70% of all operating projects and many more in earlier stages of development. With its experi- ence in exploration, drilling, well testing, resource analysis, resource quanti cation, modeling, and risk mitigation, GeothermEx has supported nearly $13 billion in project nancing for more than 7,500MW of geothermal power. Acquired by Schlumberger in 2010, GeothermEx is actively lev- eraging and adapting Schlumberger technologies for application in geothermal projects. www.geothermex.com
Teranov Geothermal Energy
Teranov, along with KiTerGeo (a Kidova-Teranov Joint Venture) provides project management, en- gineering, and eld services for the development of high and medium temperature geothermal pro- jects over EMEA, Latin America, and the Carib- bean. They offer due diligence, capacity building, prefeasibility and feasibility studies involving a broad geoscience approach and innovative tools for resources evaluation and assessment, and reservoir characterization and forecasting all the way up to plant completion and operations. www.terranov.com
