DEVELOPMENT STRATEGY
Science, engineering and market dynamics define the economic outcome and the risks involved in upstream development. A methodical approach is require.
SHALE ENGINEERING
Traditional reservoir engineering cannot address complex behavior in tight oil. Predictive approaches need to include realistic and practical geomechanics.
INNOVATIVE DESIGN
Applying shale science to known geological parameters results in optimal design with few itterations. Dramatic improvements can be achieved Instead of incremental improvements.
DIGITAL TRANSFORMATION
Modern field development calls for high capital logistical efficiency, making “on time” design adjustments based on latest information at hand. Digital transformation enables .
RESOURCE ASSESSMENT
Besides commercial and regulatory considerations, the potential to produce oil and gas depends on multiple variables that need to be examined; some natural, some operational. Attention must be given in their dependencies.
ENHANCED OIL RECOVERY
Injecting Natural gas, CO2 and, or heating are the most common methods to enhance or introduce drive mechanisms. Besides heavy oil, new approaches in tight resource plays enable.
World Wide Experience
As a world-wide consultant, served as a key contributor in high end projects working with major oil and gas corporations, agencies and independents. A trusted advisor and asset evaluator in the era of intensified development.
