Interpretation of Cement Bond Logs
A critical part of Well Integrity

Prove safe oil and gas operations through Well Integrity Management

Cement bond log measurements and mechanical integrity evaluations are critical concerning Well Integrity and more particularly casing integrity. New and revised rules and regulations require that operators prove that the barriers of each well is intact or integral. Our support for your well are in the areas of casing integrity. Knowing the condition of the well concerning cementation and casing are the primary services that ArchDrill offers.

Our main service offering is cased hole wireline data interpretation of ultrasonic, sonic (CBL-VDL) and multifinger tools. We also offer casing integrity assessments based on the ​measurement data.

Well integrity, in regard to oil and gas wells, is defined by NORSOK D-010 as the "Application of technical, operational and organizational solutions to reduce risk of uncontrolled release of formation fluids throughout the life cycle of a well.”  Wikipedia  

Gain Knowledge and Reduce Risk

An interpretation or evaluation is designed to increase knowledge and reduce risk. To help you make decisions, that  is the goal of our reports. This is done through a holistic approach to well info and measurement data. 

This includes all oil and gas production wells, injection wells and storage wells​, as well as geothermal wells.

Well Integrity includes Casing Integrity

Cementation and Casing Evaluation 

The evaluation of the casing integrity starts with planning and ends with the final abandonment. Through out the life of the well that casing and tubing has to be monitored for integrity in order to prove that safe operations are being maintained. A loss in the safety of the primary or secondary barriers may result in a catastrophic disaster. This can be avoided through wireline measurements and in-depth evaluations and advance data interpretations.

Cement Bond Log Interpretation

Wireline logging data presented on one page to aid the interpretation by creating an overview.

As a part of the analysis, we require more than a PDF log from the measurements. Our preference is to import digital logging data into our software for more in-depth analysis. Rather that being limited to the depth scaled data in the logs like 1:1000 or 1:200, we can zoom in and out to better view that data with a scales like 1:50 or 1:5000 or even 1:1 for high resolution data. We also have the flexibility to modify the curve scale and image colors to improve the presentation. Ideally, we like to use the DLIS files which have compressed digital data with the images included. 

If you are in the process of measuring your wells with cased hole tools like Multifinger (PMIT, MIT, MSC), Ultrasonic (USIT, URS, CAST) and/or Cement Bond Log (CBL-VDL, SBT, SBL, RBT) we can support you with interpretation services and money can be saved.  

ArchDrill provides support to wellbore owners in running cased hole wireline campaigns. We also provide Cement bond log interpretation service for wireline logging data concerning casing integrity. This is provided in the form of a custom made report which meets your reporting requirements.

In your office or on the wellsite, we can support your operations.
