Fractures : A challenging reservoir component Reservoir quality is usually very variable in fractured reservoirs due to their high degree of geological heterogeneity. Understanding the role of fractures, predicting sweetspots and managing reservoir behaviour are challenging tasks, but successful exploitation can lead to rich rewards. GeoScience’s multi-disciplinary team has the skills and experience to help you reduce risk and build confidence in decision making for technical evaluations and wellsite operations. We offer services in four key areas. |

Fracture Studies
Our staff
have extensive experience of working with
well data, This ranges from drilling and completion issues, through data
acquisition by logging, coring and testing, to analysis and
interpretation of wellbore datasets, particularly borehole image logs We
also go a step further by integrating the various downhole datasets
and using the results to build and constrain geological models and
to calibrate seismic-based reservoir descriptions.

Reservoir Description and Modelling
Construction of geological models for reliable prediction of
porosity and permeability distributions in fractured reservoirs is
an outstanding industry challenge. Our approach is to maximise the
value contained in well data and also in outcrop analogue information.
From these our structural geologists can extrapolate and integrate
with reservoir-scale datasets to derive calibrated models and
associated parameters. Geomechanics of Fractured Reservoirs There is a growing awareness of the role that contemporary in-situ stress often plays in fractured reservoirs, mainly by its influence on fracture permeability and flow anisotropy but also on wellbore stability (see our BRM pages). Our geomechanics team will establish the reservoir stress condition and evaluate the impact of stress on reservoir behaviour and on operational activities. We also prepare the inputs to field-wide geomechanical models. A recent estimate suggests that fractures are important in about 60% of the world's hydrocarbon reservoirs, although ‘fracture denial’ is not an uncommon phenomenon through the industry. Geologists and engineers alike are increasingly faced with evaluating the role of fractures to underpin development decisions. We offer a field-based training course which provides a firm basis for those whose task is to deliver the goods on these challenging reservoirs. |
