3F - Corinth

Faults, fractures & Fluids - Gulf of Corinth project

The goal of this project is to better understand fluid transfer in and around fault zones and through carbonated reservoirs. The full set of data we will collect on stress, strain, fluid, core and boreholl imaging will also allow us to understand the fault hydraulic and mechanical behaviour and to calibrate all our tools on fractured reservoirs, especially by comparing the opening of the fractures with the stress field.

WP1: Fractures network (IFP, Enterprise Oil, IPGP)
For the description of the damaged zone around the fault, the cored section we will increased to 200 m. Various tools will be used to describe the anisotropy of the material (DSI, FMI, VSP, local seismic network). The current theory correlates anisotropy with the stress field, so additional stress measurements will be carried out in the wells and in the surrounding area. A mini 3D survey will be shot around the well on a surface geophone array in order to illuminate the well vicinity.

WP2: Permanent captors (IFP, Schlumberger, Postdam)
Two new technologies on permanent monitoring captors will be tested:
one based on fibre optics to record strain variation versus time (it will be installed in the deepest well)
one based on cemented electrodes. A special well will be dedicated to this experiment to monitor the flow of the conductive fluid along the fault plane.

WP3: Tomography (geofrance Azur, UPSL)
Microseismicity will be recorded from the sufrace on a dense network for 4 months. The sites will be installed for repetitive operations and therefore cemented (in the case of a large seismic event, the sites could thus be re-used for a renewed survey). The data from wells and surface network will be used to define the characteristics of the area in terms of velocity and attenuation.
Interpretation will be done jointly by the specialists of reservoir microseismicity and academic seismologists.

WP4: Fluids (ING, IFP)
The fluid flow will be sampled in all the wells and continuous chemical description will be conducted over a couple of months. Measurements will cover a large spectrum of elements including noble gases (ratio + isotopes) in order to understand the source of these elements. The compositions of well fluids, cements and paeofluids will be correlated by modeling the fluid/rock interactions.

WP5: Geomechanical modeling (IFP, NTUA, CEMRES, Un. Lieges, Un. Edimbourg)
All the data will be used to define better the rock deformation and the fluid flow in faulted and fractured material. The coupling between the geomechanical approach (used in the academic world) and the large scale fluid flow (used in oil companies) will be described.
