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.

4D Visualization As a Geothermal Exploration Method

The geothermal exploration method often involves an analysis of data related to various surface and subsurface geoscientific properties. Geoscientific professionals and engineers use different evaluation methods to derive a conclusion on the feasibility of the potential geothermal project.

Well-Collision Avoidance: Mitigating Risk in Mature Field Development

When developing well-collision avoidance strategies, petroleum professionals should rely on data integration and visualization to aid in well planning. Enhanced visualization gives engineers the ability to see more of the subsurface and provides them with additional opportunities to prevent drilling into danger zones or colliding with established wells.

An Integrated Approach to Mature Field Production Optimization

Among the many challenges of managing a mature oil field is the need to obtain an accurate understanding of its remaining recovery potential. Greater accuracy in assessing characteristics that influence recovery—geologic variability changes in fluid saturation, water cut, microseismic events, location and viability of aging infrastructure—enables asset teams to make better decisions regarding mature field production optimization.

Microseismic Monitoring: Measuring the Effectiveness of Reservoir Stimulation

Microseismic monitoring is helping reservoir engineers plan and execute more effective stimulations to maximize recovery. Over the past two decades, innovations in surface array and downhole geophone technologies—combined with algorithms that filter “noise” from sources such as pumping and surface operations—have improved the accuracy of locating and characterizing microseismic events.

How to Obtain Subsurface Data Management With Integrated Software

During hydrocarbon exploration and development operations, vast amounts of subsurface data are collected and generated. The amount of disparate data collected makes it difficult to obtain subsurface data management for precise decision-making. The accuracy and timeliness of the decision process can be greatly enhanced using software capable of viewing all data in a single platform.
