Surface Well Test Equipment

We offer integrated well testing in the exploration, appraisal and development phases of oil and gas wells. With almost 1 decades of experience coupled with state of the art equipment and technical expertise, our aim is to provide precise testing results. Clients avail our services for extended well tests, leading to early production facilities that allow them a force multiplier, further monetising their exploration wells in the shortest of time. This is executed prior to a more detailed engineering study for permanent production setups.
Our well testing tools were created and produced in compliance with global standards. All materials adhere to international quality standards such as CE/PED, ASME, API, GOST, and others. These standards are set in the United States, Middle East and Asia.
