Scientific Drilling’s Cased Hole Services provides reliable, technologies for assessing well integrity, determining flow profiles and evaluating reservoir saturation. Our technology is deployed for myriad data acquisition requirements in oil & gas and geothermal wells around the world.

Scientific Drilling International is unique in providing services with its proprietary approach to developing technologies that give accurate, sensitive downhole measurements reliably and cost effectively. The in-house design and manufacturing of tool components, down to the sensor level, ensures product integrity and performance. This differentiates SDI as a Cased Hole Service provider in O&G, geothermal, and mining industries.

The provision of downhole measurements is only part of providing useful results to our clients. Our Data Analysis Centers in Aberdeen and Bangkok turn data into meaningful information. Our log analysts have extensive exposure to both the field environment and data interpretation, with over 100 years of combined experience. Our expertise and portfolio provide you with the assurance to rely on Scientific Drilling to deliver results, which help optimize production, maintain well integrity and improve reservoir understanding.

SDI has a track record of reliability in harsh environments; extreme temperatures, tight, cork screwed tubing, remote locations, horizontal undulating wells and corroded deformed well access issues. Bring your difficult wells to us.

    Reservoir Evaluation

    The MPNN tool is a cost effective way to run pulsed neutron logs on slickline or coiled tubing. This short, slim tool string can get in many wells where larger competing tools may have difficulty accessing the zones of interest.

    Flow Logging

    Our slim, harsh environment tool strings allow clients to obtain data with minimal impact on the flow. Applications include flow profiling, water or gas entry detection, leak detection and Selective Inflow Performance (SIP) to determine current formation pressure and permeability.

    Well Integrity

    Our in-house developed caliper tools provide accurate and high resolution measurements of wellbore anomalies to troubleshoot issues. A range of tools are available with temperature ratings of 428°F and 600°F (220°C and 315°C) for oil & gas and geothermal applications respectively. In support of the caliper we also have cameras, short interval gyro surveying, and visualization software to best understand the well for early detection of deformities, corrosion and leaks inside the tubing or casing.
