Multiyear Geothermal Drilling Contract in Indonesia

Halliburton has been awarded a multiyear contract by KS Orka Renewables Pte. Ltd. to support geothermal well construction at the PT Sorik Marapi Geothermal Power (SMGP) and PT Sokoria Geothermal Indonesia (SGI) projects in Indonesia. The agreement spans several development phases and strengthens Halliburton’s involvement in geothermal energy within its Low Carbon Solutions portfolio.

Integrated Well Construction Services
Under the contract, Halliburton will provide a full suite of drilling and well construction services, including directional drilling, cementing, drilling fluids, and drill bit technologies. These services are tailored to geothermal applications, where high-temperature and high-pressure conditions require specialized materials and well designs.

Directional drilling enables precise placement of wells within geothermal reservoirs, improving resource access and maximizing thermal recovery. Cementing services are critical for zonal isolation and well integrity, particularly in geothermal systems where thermal cycling and corrosive fluids can affect casing performance. Optimized drilling fluids and bit selection support penetration rates and operational efficiency in hard rock formations commonly encountered in geothermal fields.

The integrated service model is intended to improve drilling performance, reduce non-productive time, and lower cost per foot drilled.

Projects in Sorik Marapi and Sokoria
The SMGP and SGI projects are part of Indonesia’s broader geothermal development strategy. Indonesia holds some of the world’s largest geothermal resources due to its location along the Pacific Ring of Fire. Expanding geothermal capacity supports diversification of the national energy mix and reduces dependence on fossil fuels.

The collaboration brings together KS Orka Renewables—operating within a corporate group affiliated with Kaishan Group Co., Ltd.—and Halliburton’s drilling expertise. KS Orka has experience in delivering cost-efficient geothermal wells, while Halliburton contributes advanced drilling technologies and operational execution capabilities.

Supporting Low-Carbon Energy Deployment
Geothermal power provides baseload renewable electricity with minimal direct emissions compared to conventional thermal generation. Efficient well construction is a key factor in project economics, as drilling represents a significant share of total geothermal development costs.

By optimizing directional drilling, cementing strategies, and drilling fluid performance, the partners aim to accelerate project timelines and improve cost efficiency. This contributes to expanding geothermal capacity in Indonesia while supporting reliable, low-carbon power generation.

The contract reinforces Halliburton’s strategic focus on geothermal applications within the evolving global energy mix and highlights the role of integrated drilling solutions in advancing sustainable energy infrastructure.
