Reservoir Integrity
The assessment of reservoir integrity encapsulates many disciplines related to the mechanical strength of the rock. Reveal handles these technical challenges with integrated geo-mechanics and chemistry. For example CCS; dissolving of CO2 in water dissolves or precipitates minerals with associated potential rock weakening, as well as increased pressure and stress that may fracture cap rock.

Enhanced Oil Recovery
The economic assessment of complex interactions associated with EOR requires many integrated studies, including well and completion delivery, reservoir transport with changing temperature, chemistry, adsorption, phase behaviour and other rock/fluid interactions. These can be incorporated into sector and full field studies in Reveal to see the impact on productivity.
Applications

Unconventionals
Stress changes play a fundamental role in the dynamic behaviour of tight shale reservoirs. For example, the generation of fractures, interaction between wells and changes in stimulated rock volume permeability with drawdown. Reveal models the propagation of stimulated fractures based on the reservoir’s geo-mechanical properties and well performance. Additionally, analytical transient IPRs are used optimise the production phase using an integrated network model.

Flow Assurance
The greatest impact on productivity is near and within wells. Scale, sand or other solids may impact on well performance. Reveal has been developed to capture the physical processes that lead to the dynamic changes of a well’s deliverability over the life a field.

Water Injection
Injection waters can vary in temperature, chemistry and other filtrates compared with reservoir waters. Additionally, high pressures and reduced temperatures associated with injection can induce local fractures. Reveal combines all of these features to make reliable calculations of injectivity, and hence the challenges of field optimisation can be easily addressed.
Applications
Multi-layer water injection thermal fractures controlled by upper layer injection ICVs
