Exploration and Appraisal
Your reliable partner in integrated E & P subsurface solutions
We deliver a broad range of studies based on various data sources and integration with the objective to support exploration and appraisal activities by lowering exploratory risks through a robust proven technical expertise and comprehensive workflow for an in-depth evaluation in both conventional and unconventional resources. We can particularly help with the following multi-disciplinary studies to unlock additional resources:
Low permeability reservoirs (i.e. <0.1 -0.001millidarcies) are commonly labelled as tight gas or tight oil reservoirs. New developments of drilling, completion and stimulation technologies (including horizontal pad drilling, energized slick water fracturing, zippers frack type, chock management… etc.) have facilitated commercial production from those reservoirs at current commodity prices.
This integrated analysis will subsequently lead to comprehensive fluid flow behavior, which can help to select the best appraisal and development strategy of the field, including optimized wells completion and trajectory.
In naturally fractured reservoirs, the effect of the fractures is enormous on reservoir production performance. Hence, understanding the nature of a fractures network and its relationship to the critical factors such as the rock matrix mineralogy, diagenesis, matrix porosity types, fluid properties, tectonic setting and regional structural configuration is paramount to avoid optimistic models and economic failures.
Fracture identification, characterization and interpretation whether it’s from outcrops structural studies or from subsurface data is the first part of the strategy of integration of key geological data to provide a rational and representative description of the fractured formations conditions and importantly the connectivity that depends on the relevance of the question we seek responses to:
The best answers for the right questions provide a scalable and verifiable approach for understanding the effects and influences in terms of fracture connectivity, compartmentalization, specific well locations, completions, trajectories, and potential effectiveness for hydraulic fracture stimulation.
Global petroleum exploration is currently undergoing a strategic shift from conventional to unconventional hydrocarbon resources. Unconventional hydrocarbon resources (including tight oil and gas, shales, and coalbed methane) are becoming a significant component of world energy consumption.
Shale resource systems for oil and gas differ from the conventional petroleum plays in terms of trap conditions, reservoir properties, combination of source and reservoir rocks, accumulation features, percolation mechanisms, and occurrence features.
integrated workflow for unconventional shale has been developed that incorporates basin analysis elements such as paleo-structural with burial history reconstruction and thermal maturity, litho-facies, sequence stratigraphy, organic and mineral geochemistry, petrophysics, geomechanics, and 3D micro-seismic analysis. The workflow encompasses a variety of analytical techniques. It is designed to identify the potentially areas and intervals for targeted horizontal drilling.
