Stimulation Geomechanics

Stimulation design with a geomechanical perspective

Comprehensively stimulating the right zones improves recovery. To ensure the best result, the geomechanics team developed a field-wide geomechanical approach to stimulation design that accounts for changes in local stress and containment. It improves the accuracy of hydraulic fracture predictions and enhances stimulation efficiency and production rates. In fractured reservoirs, a reservoir mechanical earth model (MEM) predicts induced hydraulic fractures and simulates production while considering complex fracture interactions.

Model-based approach

Creating a reservoir MEM helps

  • identify key properties that may affect stimulation design
  • determine relationships between properties and production
  • predict locations with better production potential
  • design fracture parameters
  • identify well location and spacing.

Monitor while fracturing

Schlumberger geomechanics experts also apply a methodology that utilizes microseismic events recorded during a hydraulic fracture treatment, along with other rock properties, to help monitor well producibility by tracking and visualizing the hydraulic fracture extent as it is created. By using a MEM and monitoring fractures in real time, operators are enabled to optimize each well by monitoring a fracture path and decide when to stop pumping.
