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 Scientific Drilling International as a Cased Hole Service provider in the oil and gas, 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.

Scientific Drilling International has a track record of reliability in harsh environments: extreme temperatures, tight, corkscrewed tubing, remote locations, horizontal undulating wells, and corroded deformed well access issues. Bring your complex wells to us.

Our suite of Cased Hole Services and tools include: Reservoir Evaluation, Flow Logging, Well Integrity, and Ancilliary Services.

Watch a recap of our webinar on this topic.


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

Well Integrity

Our in-house developed caliper tools provide accurate and high-resolution measurements. That is to say, these measurements of wellbore inconsistencies to troubleshoot issues. A range of tools is available with temperature ratings. For example, 428°F and 600°F (220°C and 315°C) for oil & gas and geothermal applications. In support of the caliper, we also have cameras, short-interval gyro surveying, and visualization software to understand the well better. Most importantly, for early detection of irregularities, deterioration, and leaks inside the tubing or casing.

Ancilliary Services

Scientific Drilling can also provide Wireline (slickline or electric line), capillary tube services, broaching, fishing, fluid sampling, FreePoint Backoff, plug/packer setting and Perforating.
Additional visualization technologies are available including electromagnetic thickness, acoustic scanning and array production logging tools.
