Unlocking Impermeable Geothermal Reservoirs: Hydraulic Stimulation, Menengai and Olkaria

Unlocking the Impermeable Reservoir: Lessons from a 30-Year Reservoir Engineer An Alphaxioms interview with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Context: Menengai East and Olkaria Central. Every geothermal developer knows the moment.  The rig is gone and the money is spent. The well is drilled to depth, the temperature is there, and then the well will not flow. The heat is real, but the connection between the well and the reservoir is not. Wells like this sit at the centre of one of the most important questions in geothermal development: what do you do with a tight reservoir? Walk away and drill again, or find a way to unlock what is already there? To explore the question, Alphaxioms spoke with Richard Joseph Holt, Principal Consultant in Reservoir Engineering at RESPEC . Richard brings 30 years of global experience in geothermal energy.  We framed our questions around two settings, Menengai East and Olkaria Central, and asked him how ...

Chevron Goes Slow On Oil For Indonesian Geothermal

Chevron and PGE Join Forces to Unlock Geothermal Potential in WKP Way Ratai

On September 25, 2024, a monumental step was taken in Indonesia’s renewable energy journey. PT Cahaya Anagata Energy (CAE), a joint venture between PT Pertamina Geothermal Energy Tbk (PGE) and Chevron New Energies Holdings Indonesia Ltd., officially received the long-awaited Geothermal Permit (IPB) for the Way Ratai Geothermal Working Area (WKP) in Lampung. This collaboration promises to set new benchmarks in geothermal exploration and development, marking a pivotal moment for Indonesia’s clean energy ambitions.

A Breakthrough in Energy Bureaucracy

The symbolic handover of the IPB took place at the Directorate General of New, Renewable Energy, and Energy Conservation (EBTKE) in Central Jakarta, with key energy leaders present. What makes this milestone even more significant is that this was the first geothermal permit processed entirely online through the Online Single Submission (OSS) system. This technological shift signals Indonesia’s commitment to reducing bureaucratic hurdles and paving the way for faster renewable energy projects.

Director General of EBTKE, Eniya Listiani Dewi, emphasized the government’s dedication to renewable energy development during the handover ceremony. “The government fully supports geothermal energy development, and we’ve streamlined processes to ensure green energy exploration proceeds efficiently,” she stated, signaling a new era of regulatory efficiency.

USD 28.85 Million Investment for Exploration

The issuance of this permit is not just about paperwork; it’s a precursor to real action. PT CAE will initiate exploration surveys to identify geothermal sources in WKP Way Ratai. With an investment of USD 28.85 million for the exploration phase, this project signifies a serious commitment from both Chevron and PGE to tap into Indonesia’s vast geothermal potential.

“WKP Way Ratai is part of a grand strategy to strengthen PGE’s geothermal portfolio,” said PGE President Director Julfi Hadi. He underscored the importance of strategic partnerships like this one with Chevron, which aims to contribute to sustainable energy development while benefiting local communities.

The Road Ahead for PT Cahaya Anagata Energy

The journey to geothermal energy production is a rigorous one, and PT CAE’s first task is to conduct exploration surveys. This includes geological, geophysical, and geochemical studies, known as 3G, which will determine the viability of further development. With transparency and community involvement at the heart of this process, PT CAE is poised to ensure that this project not only provides clean energy but also creates lasting benefits for the people of Indonesia.

President Director of PT CAE, Wahyu Budiarto, expressed gratitude to the government for the support, saying, “We are committed to conducting exploration with the highest safety and environmental standards.” He highlighted that stakeholder involvement, particularly from surrounding communities, would be key to the project’s success.

A Strategic Leap for Indonesia’s Clean Energy Future

This collaboration between Chevron and PGE is more than just another energy project; it’s a testament to Indonesia’s growing role in the global energy transition. With the government’s active support and the strategic involvement of industry giants, the WKP Way Ratai project is set to propel Indonesia further into the forefront of geothermal energy production.

As exploration begins, all eyes will be on PT Cahaya Anagata Energy as it navigates the challenging, yet rewarding path toward geothermal energy development, offering a greener, more sustainable future for Indonesia and beyond.

The WKP Way Ratai project embodies Indonesia’s ambitions for a cleaner energy landscape. With Chevron and PGE at the helm, this partnership not only promises to unlock geothermal potential but also sets the tone for future collaborations in the renewable energy space. As exploration kicks off, Indonesia’s geothermal dreams edge closer to reality, driven by innovation, strategic partnerships, and a shared vision for sustainability.

Global Geothermal Policy Outlook for 2027 Across Key Markets

Global Geothermal and Energy Policies for 2027: A Future Outlook Introduction The next phase of global geothermal development will be shaped not only by geology and technology, but increasingly by national energy policy . Governments are now treating geothermal as more than a niche source of heat or power . They are beginning to see it as a practical option for firm low-carbon electricity, district heating, industrial heat, and energy security. That shift matters because geothermal projects are unusually sensitive to policy design. Exploration is capital intensive, drilling is expensive, subsurface risk is real, and project timelines can stretch over years before revenue begins. In other words, geothermal is not just an engineering challenge. It is also a finance, regulation, and infrastructure challenge. Looking toward 2027, five countries offer a useful benchmark for where geothermal policy may be heading: the United States, the United Kingdom, Norway, Canada, and France. Each countr...

Geothermal Funding, August ,September 2027 With Intelligence into 2028

Geothermal Funding in August and September 2027: Investment Outlook and Intelligence Into 2028 Geothermal funding in August and September 2027 is likely to focus on projects that can demonstrate commercial resource potential, credible drilling plans, secure offtake, and a clear path to construction. The market will increasingly move beyond broad technology experimentation toward financeable geothermal assets supported by government grants, development-finance institutions, strategic investors, utilities, and corporate power buyers. The most significant investment themes will likely include enhanced geothermal systems , exploration drilling, closed-loop geothermal , data-center power supply, conventional geothermal expansion in East Africa, and blended finance for emerging markets. By 2028, investors are expected to distinguish more sharply between companies with proven technical performance and those still dependent on laboratory results or unconfirmed resource estimates. The 2027 Fun...
