Although the Permian Basin has reinvented itself over the past five years, there is an abundance of hydrocarbons that is yet to be recovered. While improvements in drilling and completion efficiency has driven down the cost per barrel of oil equivalent, advances in logging techniques and integrated modeling has led to the development of better completion strategies and increase in the hydrocarbon production. Advanced modeling workflows that were initially developed for the unconventional reservoirs have also been applied to conventional reservoirs in an effort to boost production.

Advanced logging tools along with more efficient logging techniques have led to an increase in the acquisition of subsurface data. Information collected includes porosity, permeability, water saturation, rock mechanics, fractures, etc. which can be used to perform advanced fracture modeling and numerical reservoir simulation. This presentation presents workflows, which leverages on the acquired log measurements for performing lateral landing point evaluations, completion optimization and well spacing.

Fracture models such as Unconventional Fracture Model (UFM) are capable of performing complex fracture simulations which are then fed into a numerical reservoir simulator for drainage mapping. Calibration of reservoir model act as predictive tool to understand parameters such as proppant/ft, cluster spacing, number of clusters per stage, stage length, etc. Depletion around the wellbore results in changes in the stress field. This stress change is captured via geomechanical finite element model (FEM) to model the changes of the magnitude and orientation of the in-situ stress due to depletion.

The variation in production from unconventional reservoirs are quite high and, it is becoming increasingly important to integrate the geological, petrophysical and geomechanical aspects of the reservoir, to mitigate the uncertainty.  The high quality of input data from log measurements aims to reduce this uncertainty in the advanced fracture and reservoir modeling workflows and are a cost effective alternative to field testing various scenarios. 


Cyrille Defeu is a Production and Stimulation Engineer at Schlumberger. Cyrille currently works with the Production Technology Integration Group where he helps optimize production in various basins by leveraging technology, software and data integration. His focus includes maximizing pad production and infill wells optimization in depleted environment. His oil and gas career started in 2011 in North Dakota as field engineer, where he supported operations and field implementation of new stimulation technologies in Williston Basin. Cyrille earned his B.S. degree in Chemistry from University of Buea, B.S. and M.S. degrees in Petroleum Engineering from Texas Tech University.
