Techlog Shale

Achieving production objectives with full stochastic evaluation of exploration portfolios.

Techlog shale offers the latest formation evaluation methodologies and completion strategies for application in shale gas and tight oil reservoirs. As an integrated module inside Techlog wellbore software, Techlog shale facilitates robust interpretation while keeping input parameters to a minimum. Efficiencies and optimization can be achieved throughout the evaluation and production processes by using multiwell workflows, contextual guides, and automation.

Model shale petrophysics

Understanding lithology is key to evaluating shale plays because it directly influences the porosity distribution in the rock and the geomechanical properties of the formation. The Techlog shale petrophysics workflow empowers you to work with the data you have, such as a triple-combo, advanced spectroscopy, or nuclear magnetic resonance logs. Using this information, you can build rapid, robust models that explain complex mineralogy, porosity, and fluids present in the formation.

Predict hydrocarbon volumes

Techlog shale enables you to estimate the hydrocarbon volumes in place for gas, condensates, or oil at reservoir conditions—computing both free and adsorbed gas fractions. Core-derived isotherms from many shale plays are integrated into the module for adsorbed gas computation, with the ability to input local data when available.

Stimulate using local stresses

When completing the well and planning stimulation stages or perforations, the far-field stresses need to be factored in to ensure the completion is placed in the most appropriate stress area. The anisotropic geomechanics tool calculates the mechanical properties and horizontal stresses in layered rock that can be used alongside reservoir quality information for optimal completion planning.

Design and plan completions

Complete your wells for optimal stimulation and production with the Techlog shale completion advisor, which empowers you to rapidly design your own completions using readily available contextual information on reservoir quality and stimulation. Optimizing perforations and stage placements are key to effectively producing for the length of the lateral. Further engineering or evaluation on the effects of stimulation on well productivity is provided by the Intersect high-resolution reservoir simulator and the Visage finite-element geomechanics simulator using the Petrel subsurface software and Mangrove engineered stimulation design in Petrel subsurface software.

Build a calibrated mechanical earth model

Efficient drilling is paramount to any successful oil and gas company. Using Techlog shale, users are guided through the different steps required to build a calibrated mechanical earth model (MEM), using data from image, sonic, and pressure measurements. The MEM helps you gain a thorough understanding of the properties of the rock surrounding the wellbore as well as the in situ stresses. This results in a mud-weight window for different deviations and orientations as well as failure prediction for comparison with real-time data. Techlog shale also enables you to choose the appropriate intermediate casing point, decide on the optimal landing point for accessing the reservoir, and determine the mud weight for your operation.
