Abstract
A matrix acidizing monitoring system wherein a sensor array is operably associated with a matrix acidizing bottom hole assembly and contains first and second sets of sensors that detect a matrix acidizing operational parameter at different times at one or more particular locations along the wellbore. This allows the effectiveness of the acidizing to be modeled.
Claims18
A matrix acidizing monitoring system comprising:
- a bottom hole assembly to conduct matrix acidizing in a wellbore;
- a sensor array operably associated with the bottom hole assembly and having first and second sets of sensors, each of the first and second sets of sensors being operable to detect a matrix acidizing operational parameter at a location in the wellbore;
- the first set of sensors detecting the parameter at the location at a first time as the first set of sensors is moved past the location;
- and
- the second set of sensors detecting the parameter at the location at a second time as the second set of sensors is moved past the location.

A method of monitoring a matrix acidizing operation within a subterranean formation in a wellbore, the method comprising:
- disposing a bottom hole assembly proximate the formation in the wellbore;
- conducting a matrix acidizing operation through the bottom hole assembly into the formation;
- detecting a matrix acidizing operational parameter at a location within the wellbore with a first set of sensors as the first set of sensors is moved past the location;
