MEMORY MULTIFINGER IMAGING TOOL MEMORIZADO – MIT

MIT is an edge technology probe designed to measure the internal dimensions of both tubing and casing by use of extensions that make direct contact with the surface.

OPERATION PRINCIPLE:

The probe is run into the well by use of a slick line, where the inside diameter of the tubing is measured using tungsten sensors fitted to flexible arms which extend with the help of a motor to the diameter of the pipe.
These arms record any changes in the inside diameter which are transmitted by an actuator that converts mechanical movement into voltage which is in turn digitalized and stored in the probe’s memory.   
The probe has an inclinometer that logs the deviation and inclination of the logging string.
Additionally, changes in the temperature of the inner surface are recorded which are used to make additional corrections in the interpretation software.

USES:

Calculate corrosion damage, chemical precipitation and scaling
Map perforations and assess their integrity.
Location of strain, restrictions, deposits and tubing damage
Tubing’s clean out assessment.

LOG RESULTS

The data obtained by the MIT are stored in the memory of the probe which are further on analyzed by specialized post-process software  (MITCal, MITPro y MITView), that provides a  3D image that represents the current state of the tubing, a statistical analysis with graphs that illustrate the wear and tear of the metal and the  damage profile of the pipe.
Data on the probe’s position are recorded in the memory or transmitted to the surface. Data from each extension are monitored separately.
