This paper presents recent case studies where down-hole pressure and temperature sensors, run on coiled tubing, provided real-time measurement of matrix acid treatments in the Gulf of Mexico. The information obtained during these jobs allowed on-site design and execution changes to the treatment. Four case studies are presented to demonstrate how the sensor information was used to optimize the treatment of each well.
