Minimizing the Uncertainty of Well Trajectory Calculations

The greater the wellbore length the greater the degree of uncertainty in determining the actual trajectory location. A well-understood fact: Absolute accuracy is nearly impossible because of the inherent errors in measurements (sensors, measured depth, axial or cross-axial interference, geomagnetic field uncertainty). In extended reach wells using conventional MWD techniques, poor tool error models can create positional uncertainty that can be tens of feet larger than a high quality tool.

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.

Enhancing Structural Interpretation of Seismic Data With Velocity Modeling

While there are traditional approaches to the structural interpretation of seismic data for oil exploration and velocity modeling in the industry, these approaches can be enhanced through advancements in technology. Without the ability to integrate and visualize all relevant data in a comprehensive environment, professionals may overlook valuable pays.

Using Drilling Data Analytics to Improve Drilling Performance

When drilling engineers are looking for insights that lead to improved drilling performance, they often turn to drilling data analytics. Those critical insights come in the form of drilling data that paints a realistic picture of subsurface conditions, steering engineers in the right direction during a drilling campaign.

Geothermal Visualization: Comprehensive Examination of Geothermal Data

The harnessing of geothermal energy from the subsurface involves a multi-step process of resource identification, exploration, development, and production. Data plays a guiding role in making each phase of the geothermal development project a success.

Understanding the Importance of Data Visualization in the Oil and Gas Industry

Data-gathering and processing can be a laborious task that requires extensive expertise. But the best software offers easy-to-read data to personnel, irrespective of their discipline or specialty. Analysts need data visualization tools that merge data across multiple disciplines in the oil and gas industry, helping users make sound decisions that enhance upstream or downstream campaigns.
