Koomey Unit and Pressure Control for geothermal project

Sector: Geothermal
Country: Netherlands

Supply of Koomey Unit and Pressure Control Equipment, including large-sized Quick Test Subs and Crossovers (13 5/8″ and 12″), for workover and coiled tubing activities on a geothermal well in the Netherlands. The solutions were designed to allow the passage of workover assemblies and jet pumps with an OD up to 9″, ensuring operational continuity, safety, and documentation compliant with project requirements, supporting the development of geothermal energy as a renewable source.

Custom chemical formulations for Production Enhancement

Sector: Production Enhancement – Chemical Supply
Country: Kazakhstan

Joint development and supply of custom-made chemical formulations, in collaboration with the Client, for production enhancement and plant performance optimization applications. The program allowed an improvement in process efficiency and a significant reduction in operating costs.

Supply of 15K PSI Well Control Equipment

Sector: Workover
Country: Turkmenistan

Supply of 15K PSI Well Control Equipment for a client operating in Turkmenistan. The equipment was prepared, tested, and certified in accordance with the operator’s technical requirements for use in a field characterized by complex operating conditions. The technical support provided during alignment and scope definition meetings was crucial for the correct configuration of the solutions.

Coflex Hose for Well Testing activities

Sector: Workover
Country: Turkey

Supply of Coflex Hose for a well testing project in Turkey. Technical specifications were defined in close coordination with the Client to ensure full compliance with the operator’s operational standards and QA/QC procedures. The added value of the intervention was direct field support, with operational verification and technical alignment during installation activities.
