Scientific Drilling's Cased Hole Services provides reliable, fit-for-purpose technologies. For instance, for assessing well integrity, determining flow profiles, and evaluating reservoir saturation. Therefore, our technology is deployed worldwide for mass data acquisition requirements in oil and gas and geothermal wells.

In-house tools

Scientific Drilling International provides services licensed to develop technologies that give accurate, sensitive downhole measurements reliably and cost-effectively.

The in-house design and manufacturing, down to the sensor level, ensures product integrity and performance. For example, our in-house tools differentiate Scientific Drilling International as a Cased Hole Service provider in the oil and gas, geothermal, and mining industries.

Providing downhole measurements is only part of delivering valuable results to our clients.
/ Our Data Analysis Centers in Aberdeen and Bangkok turn data into meaningful information.
/ Scientific Drilling’s log analysts have extensive exposure to the field environment and data interpretation, with over 100 years of combined experience.
/ The expertise and portfolio ensure you can rely on Scientific Drilling to deliver results. In other words, that help optimize production, maintain well integrity, and improve reservoir understanding.

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

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

Interested in learning more about the importance of high pressure, high temperature, and the tool systems we use to address these challenges?

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 caliper tools provide accurate and high-resolution measurements. The measurements troubleshoot issues of inconsistencies in the wellbore. A range of tools is available with temperature ratings from 428°F and 600°F (220°C and 315°C) for oil & gas and geothermal applications. In addition, we have cameras, short-interval gyro surveying, and visualization software to understand better the well. We detect irregularities, deterioration, and leaks inside the tubing or casing early.

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.
