Multilateral Well Drilling Technology: Reducing Risk & Improving Production

Multilateral well drilling technologies have evolved significantly since being pioneered in the Bashkiria fields in Russia in 1953. Today, the diversity of drill string and bottom hole assembly designs combined with the ever-increasing volumes of subsurface data allow operators to more accurately understand geological conditions, identify risks, and plan and drill multilateral wells to maximize recovery.

Oil and Gas Data Management Software: Why Timing Is Important in Oilfield Analysis

Time is a crucial factor when maximizing hydrocarbon assets for all team members involved, especially when operating under tight deadlines. Analysts must develop viable extraction strategies to recover upfront costs while making a healthy profit. Engineers need fast and accurate analysis that will hasten the development phase, leading to efficient extraction campaigns in the short-term.

Exploring the Advantages of Logging While Drilling

In the wake of the shale oil boom in the United States, drillers are encountering unconventional reservoirs that require sophisticated strategy. While 95% of U.S. drilling rigs can perform horizontal drilling that, together with hydraulic fracturing, is essential to liberate shale resources, drillers need impeccable drilling technology and precise software that will utilize comprehensive geological and seismic models.

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 Seismic Monitoring of Reservoir Change Through Visualization

When it comes to hydrocarbon exploration, risks are inevitable; there’s no way to completely eliminate risks but there are ways to reduce them and optimize asset production. One such mitigation strategy is 4D seismic monitoring of reservoir change.

An Integrated Approach to Seismic Forward Modeling

Seismic forward modeling is an important step to better understand complex subsurface conditions when using 3D, and especially 4D, seismic data. However, to fully appreciate the impact of the modeling results, data integration is required to set the findings in their full and correct context. Analysts are well aware of the challenges of sifting through multiple applications to manage datasets—which often leads to confusion and wasted time along the way.
