A global leader in industrial data management from the shopfloor to the boardroom, we accelerate data-driven value creation in asset-intensive industries through robust data software offerings. 

To celebrate Black History Month, Byron Gautier, a member of the AspenTech Black Leadership Forum, explores how African culture has shaped our food, drink and American popular culture.

AspenTech DataWorks is purpose-built to be the global leader in industrial data management.

Seismic data can provide useful information for prospect identification and reservoir characterization. Combining seismic attributes helps identify different patterns, for improved geological characterization. Machine learning applied to seismic interpretation is very useful in assisting with data classification limitations.

In depth imaging, depth calibration using well-tie updated velocity is generally applied to poststack data. This is the most correct type of depth calibration as it positions structures in their proper places.

One of the main challenges in seismic imaging, especially of land data, is building the near surface velocity model, as it is normally characterized by very low velocity values with different types of local anomalies. Resolving the near surface velocity model using only refraction data is insufficient, as it does not provide the required lateral resolution. Using only reflection data is equally insufficient, as it does not provide the required vertical resolution.

Geothermal energy is a key resource for providing clean, reliable and sustainable energy. Induced seismicity events, with magnitudes large enough to be felt by local communities and impact surface infrastructures, are an undesirable potential result of geothermal operations, and significantly impact social acceptance. Mitigating adverse effects is of upmost importance if one wishes to increase the number of safe, sustainable geothermal projects.

The Reykjanes reservoir, lying in a volcanic environment in Iceland, is assumed to contain supercritical fluids, whose energy content is about ten times higher than conventional geothermal systems. Drilling a well in this environment has to cope with very high temperature and pressure as well as an intensely fractured subsurface. A detailed well design can help minimize the likelihood of drilling and completion problems that could compromise the success of the project.

Aspen Economic Evaluation provides an integrated estimation solution for effective management of projects across the entire lifecycle.

Field development planning using reservoir models is a key step in the field development process. Numerical optimization of specific field development strategies is often used to aid planning, and Bayesian Optimization is a popular optimization method that has been applied in the past.
