Abstract
To determine fluid flow information associated with a well, data from plural discrete temperature sensors in zones without radial fluid flow in the well are received. The fluid flow information associated with the well is derived by combining the received data from the plural discrete temperature sensors with reservoir data that is independent of the fluid flow. That information can be further enhanced by monitoring the changes of temperature data over time.
Claims22
A method for determining fluid flow information associated with a well, comprising:
- estimating reservoir temperature;
- receiving data from plural discrete temperature sensors in zones without radial fluid flow in the well, wherein the plural discrete temperature sensors are installed in at least one sand screen assembly;
- and
- deriving the fluid flow information associated with the well according to the received data from the plural discrete temperature sensors and the estimated reservoir temperature.
A method for determining fluid flow information associated with a well, comprising:
- estimating reservoir temperature;
- receiving data from plural discrete temperature sensors in zones without radial fluid flow in the well;
- receiving data from additional sensors placed in zones that contain radial fluid flows;
- and
- deriving the fluid flow information associated with the well according to the received data from the plural discrete temperature sensors, the data received from the sensors placed in the zones that contain radial fluid flows, and the estimated reservoir temperature.
A method for determining fluid flow information associated with a well, comprising:
- estimating reservoir temperature;
- receiving data from plural discrete temperature sensors in zones without radial fluid flow in the well;
- and
- deriving the fluid flow information associated with the well according to the received data from the plural discrete temperature sensors and the estimated reservoir temperature, wherein the fluid includes at least two components, and the method further comprising combining temperature data from the temperature sensors with an estimate of relative permeability of those components to determine fluid flow information of each component.
A system comprising:
- an array of sensors deployed in a wellbore, wherein the array of sensors include discrete temperature sensors for positioning in zones without radial fluid flow in the wellbore;
- a computer to derive fluid flow information associated with the wellbore according to the received data from the discrete temperature sensors and an estimate of reservoir temperature;
- and
- a sand screen assembly that has blank sections, wherein the discrete temperature sensors are thermally contacted to the blank sections of the sand screen assembly.
