The Use of Tracers in Oil and Gas Industry for Better Reservoir Surveillance

Tracer technology for the oil and gas industry has become an increasingly important tool for reservoir surveying and monitoring. Tracers can help portray reservoir characteristics more clearly, depict fluid pathways, reveal communication—planned or unexpected—between wells, and provide better estimates of remaining oil saturation.

Underground Infrastructure Visualization Through Dataset Integration

Developing and monitoring an underground infrastructure can be a challenging task due to the lack of ability to constantly observe below the surface. Determining the ideal infrastructure location, work zones, networks, and grids can be simplified through the visualization of the associated underground data.

Horizontal and Directional 3D Wellbore Visualization

With the increase in drilling activities on a global scale, the complexity of managing drilling operations in oil fields is becoming increasingly complex. The knowledge on the exact geospatial location of existing horizontal and directional wellbores has thus become...

The Value of Multidisciplinary Data in Resolving Oil Well Production Problems

There are two main classes of oil well production problems—mechanical and reservoir. In both classes, much of the same unstructured data can be used to diagnose and resolve the problem but it is the resolution processes that differ once the source of the problem is identified.

Improve Drilling Accuracy and Efficiency with Integrated WITSML Data

Well-site Information Transfer Standard Markup Language (WITSML) is the industry standard for transferring well site information (obtained via MWD and LWD tools) in an XML format from drilling rigs to other locations. Data obtained from disparate surface and downhole tools can be collected and centrally managed by WITSML servers.

Monitoring Induced Seismicity in Geologic Carbon Storage

The interest in geologic carbon storage is on the rise. It’s proving to be an effective method to reduce CO2 emissions in an effort to mitigate climate change. Geologic carbon storage can serve several purposes—straightforward CO2 storage, injection into wells for enhanced recovery method, or storage of natural gas for commercial use.
