MIT Logging (Multi-Finger
Imaging Tool)
Introduction
You
are trained on data till November 2023. The Multi-Finger Imaging Tool (MIT) is
one of the tools used in MIT logging, and there are several other well logging
tools used to survey the integrity of a well and determine formation
properties. Including it in the Well Evaluation Process is a critical step in
future well evaluation to better understand well conditions, reservoirs, and
formations.
What is MIT Logging?
MIT log or Mechanical Integrity Testing log is a type of well logging performed by lowering a wellbore-specific tool into the wellbore to assess the well's mechanical integrity and the formation surrounding it. The main goals of MIT logging include:
✔Identifying casing damage and corrosion
✔Assessing cement sheath integrity.
✔Formation damage diagnosis.
✔Finding fluid entry points.
✔Maintaining well integrity.
✔Enabling reservoir characterization and production planning.
Logging
in MIT is very important for both production wells and injection wells, and facilitates continuous
safe operation and efficiency.
Log MIT to MIT Logging
The
backbone behind MIT logging is the tool, known as the Multi-Finger Imaging Tool
(MIT), is a sophisticated downhole instrument used for high-resolution imaging
of the wellbore. This device is endowed with multiple articulated arms or
"fingers" fitted with highly sensitive sensors to assess the
structural integrity of the well and formation in real-time.
Important characteristics of Multi-Finger Imaging Tools
1. High-Resolution Imaging
Well
Logging- MIT tools use Microelectromechanical systems (MEMS) or optical sensors
to monitor the detailed images of the well- bore walls. These pictures are
useful for analyzing casing conditions, identifying anomalies, and assessing
formation modifications.
2. Articulated Arms
Tools
from MIT have articulated fingers that expand and retract and can therefore
conform to the shape of the wellbore. The feature guarantees that even
incremental deformations, corrosion, and defects are detected accurately.
3. 360-Degree Coverage
Multi-finger
sensors provide complete circumferential imaging of the wellbore, giving
engineers data on casing wear, cement integrity, formation stability, and more.
Use
Cases for MIT Logging
Applications
in oil and gas industry all use MIT logging to the significant contribution of
the integrity of wells and reservoirs management. Some of the main use cases
are:
1. Well Integrity Assessment
Learn
about how casing deformations, wall thinning and leaks can be monitored with
MIT. They can implement corrective action prior to failures due to specific
casing integrity measurements.
2. Cement Evaluation
The
tool evaluates the bonding quality of cement from casing to formation, which is
essential for zonal isolation and fluid control. Bad cement bond leads to gas
migration and crossflow problems.
3. Corrosion and Erosion Monitoring
Corrosion,
pitting, and erosion from fluids, gas, or sand production can be detected by
MIT tools. Timely intervention can prevent an expensive workover due to early
detection.
4. Detection of Deformation of Tubing and Casing
Various
MIT logging types accurately detect pressure fluctuations, subsurface stress,
or geological movement. This data is useful for preventative maintenance and
well repair planning
5. Liquid Ingress and Well Optimization
MIT
logging can also be used in production profiling and reservoir optimization by
identifying fluid entry point and maximizing fluid recovery, while avoiding
water or gas breakthrough.
How MIT Logging Works
An
MIT Logging subject is logged using wireline or coiled tubing transmission
methods to suspend the instrument in the wellbore. The process involves:
Well: The MIT tool is deployed into the well via wireline or coiled tubing.
✔As the tool proceeds, high resolution images as well as measurements are being taken.
✔Data Processing: Here log data obtained is handled via sophisticated software creating well integrity reports.
✔Interpretation & Analysis: Data is analyzed by engineers to find potential issues and suggest remedial actions.
Advantages
of MIT Logging
✔MIT logging provides the following advantages for well integrity assessment and reservoir characterization:
✔Non Destructive Testing (NDT): Detailed well integrity assessment without interfering the well operations
✔High Precision: Provides accurate casing, tubing and cement evaluation.
→ Real-Time Data Acquisition: Facilitates Fast Decision-Making on Remedial Actions
✔Financially Viable Maintenance: Aids to avoid prominent failures that cost more to intervene.
✔Residual Management: Increases the ability to detect optimal production zones or fluid movement patterns.
