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.

Visualizing Open Hole Data for Multi-Disciplinary Teams

With the proper instrumentation, a wide range of logging data can be acquired during and after the drilling process. Open hole data acquired before casing the wellbore is generally used by production engineers and geoscientists to gain a better understanding of key subsurface and reservoir characteristics. A large volume of log data collected helps engineers and geoscientists to develop a well-informed completion strategy.

Mitigating Common Risks in Oil and Gas Production

While there’s no way to completely eliminate mishaps and failures that can create potential risks in oil and gas production, operators can implement key monitoring measures that help them find precarious aberrations sooner rather than later.

Enhanced Monitoring of Subsurface CO2 Storage by Visualizing Volume Over Time

With the increasing understanding of global warming and its causes, industries are looking for ways of reducing CO2 from entering the atmosphere to adhere to net zero goals. Subsurface CO injection and storage has been seen as a potential solution for many years for capturing the CO2 emitted from oil and gas production along with heavy industrial sources.

Mature Oil Field Redevelopment: The Role of Data Visualization and Analysis

The initial development phase of conventional oil and gas plays often delivers less than 50% of recoverable hydrocarbons. The majority of today’s oil and gas production comes from mature wells. Current oil prices do not encourage the exploration and development of new fields.

Subsurface Data Analysis and Visualization: Exploring Spatial and Temporal Diversity

Subsurface data analysis requires software that offers great flexibility. In terms of visualization, a precise level of detail is required, especially when magnifying spatial data. To obtain further analysis, it’s often beneficial when a software package has temporal features that allow users to examine subsurface conditions ranging from milliseconds to years.

Minimizing the Uncertainty of Well Trajectory Calculations

Minimizing the Uncertainty of Well Trajectory Calculations

Positional uncertainty can be calculated anywhere along the wellpath, from tie-on to total depth.A well-understood fact: Absolute location accuracy is nearly impossible because of the inherent positional uncertainty (commonly referred to as “errors”) in measurements...
