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

The use of our lightweight tool strings in challenging environments enables clients to acquire data with minimal impact on the flow. These tools find applications in various scenarios, including flow profiling, detecting water or gas entry, leak detection, and conducting Selective Inflow Performance (SIP) assessments. Most importantly, they play a crucial role in determining current formation pressure and porousness, providing valuable insights for effective wellbore management and optimization.

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.
