Abstract
A technique facilitates monitoring a reservoir property in a flowing well (22). The technique utilizes deployment of a sensor system (42,66) along the wellbore outside of a wellbore commingled flow region. The sensor system is utilized while the well is flowing during production, and the measured formation property can be used to determine/evaluate production and other well characteristics.
Claims25
A method of monitoring a well, comprising:
- deploying a sensor system along a wellbore outside a wellbore commingled flow region;
- and
- measuring a reservoir property with the sensor system while the well is producing.
A method of monitoring a subterranean reservoir, comprising:
- directly measuring reservoir layer pressures along a wellbore in a reservoir by deploying a sensor system at or outside a wellbore periphery;
- and
- monitoring the reservoir layer pressures during production to determine depletion of reservoir intervals.
A method of monitoring a subterranean reservoir, comprising:
- determining a geothermal temperature of the reservoir at multiple depths along a wellbore;
- deploying a fiber optic sensor along the wellbore in the reservoir outside of a commingled flow region of the wellbore;
- and
- utilizing the fiber optic sensor to track changes in temperature relative to the geothermal temperature at the multiple depths along the wellbore during production.
