High-Pulse Poroelasticity Protocol for geophysical monitoring of CO2 injection in reservoirs

The CO2 HPPP project focuses on a new protocol for on-site identification of saturated rocks.
The project aims to develop a new approach, on-site and at an intermediate scale between the laboratory and the reservoir to improve the estimation of hydraulic and mechanical properties and the condition of the porous medium in the reservoir system.

The project involves 4 tasks:

  • Development of a coupled measurement probe for measuring pressure and deformation during drilling. The first prototype HPPP probe is currently undergoing laboratory tests.
  • On-site experiments on a mesoscopic scale in a fractured porous carbonate reservoir. Knowledge gained from experiments with the HPPP probe will allow the introduction of a dynamic approach with a known and well located seismic source.
  • Adaptations - Developments – cross comparisons of calculations to analyse the effects of static and dynamic poroelasticity in reservoirs.
  • Imaging of the relationship between hydraulic and mechanical properties, seismic velocities and the evolution of the fractured porous environment linked to the hydro-mechanical-chemical coupling process between multisaturation with fluids (water-CO2-oil) and the rock structure.

Beyond the scientific interest, the industrial benefits are to be found in the improved methods of estimation and extraction / storage of resources. Environmentally the project will contribute to the study of artificial storage of C02 and environmental changes.

The project is now complete and now continues as the 2012-2014 ADEME project coordinated by SITES and called mHPPP, this is now moving into a pre-industrial phase of development of the technology created during this ANR.
