Abstract
An apparatus for use in a well for indicating movement of a reservoir. The apparatus may include first and second equipment assemblies connected by a telescoping connection mechanism. A sensor assembly may be provided and configured to detect relative movement of at least a portion of the telescoping connection mechanism. The relative movement of at least a portion of the telescoping mechanism may interpreted so as to correlate to the compaction or expansion of the reservoir.
Claims21
An apparatus for use in a well that extends to a reservoir, comprising:
- a first equipment assembly;
- a second equipment assembly;
- a telescoping connection mechanism between the first and second equipment assemblies;
- and
- a sensor assembly to detect movement in at least a portion of the telescoping connection mechanism.

A method comprising:
- positioning first and second well equipment assemblies in a well;
- interconnecting the first and second well equipment assemblies using a telescoping connection mechanism;
- detecting relative movement between the first and second well assemblies using a sensor assembly;
- and
- determining an indication of reservoir compaction correlating to the relative movement detected by the sensor assembly,
