Automated Bit Grading Guide
This document teaches the user to use the ZerdaLab AI-based automatic bit grading system, integrated into the Innova Web Portal and phone App.
1.0 - Introduction
Manually grading drill bits is a subjective process, as it relies on individual expertise and experience of the assessors, as well as the assessment conditions, all of which can vary considerably.
Innova has teamed up with ZerdaLab to provide an AI-based grading system within our Web Portal and App, which implements an objective, consistent and unbiased methodology wherever it is employed across the company.
This document will guide the user through the specifics of the setup and operation of this feature.
2.0 – Setup
This integration is only available via the Innova Web Portal and Mobile App. The user therefore requires the following to be able to access this feature:
Server Database Access: The portal and app operate with a server database, therefore access to a server database is required. This feature does not work with a local database.
Login Credentials: The user must have login credentials that give them access to the portal and app. In addition this access must include user permissions that allow them to add as a minimum. Read only permissions will not allow the user to access this feature.
Stable Internet Connection: This feature requires the user to upload images to the server database using either their phone, tablet or computer, which will require an internet connection
The grading is accessed directly via the Drill String Page, and the user requires the following setup:
The database tree needs to be populated down to Actual Well Level
There needs to be at least one BHA available
The BHA needs to have a minimum of a Bit entered
3.0 – Required Inputs
Please note that this feature will only work for PDC bits. Tri cone bits must be dull graded manually in the conventional way.
For the automated bit grading to operate optimally, follow these rules:
Upload one image of each blade and one image of the face of the bit. Do not upload multiple images of the same blade.
The image of each blade must show all cutters on the blade and clearly show the face of each cutter.
All images should be well lit and clear, without any blurring.
The image below shows examples of good pictures to upload. Note, it is useful, but not required, to label the blades as this helps to ensure each one is photographed, with no duplicates.
4.0 – Web Portal Interface
The following section details the required steps to grade a bit using the automated feature in the Innova Web Portal.
From the Wells List page, search for the desired well and then select it from the list
Access the Drill String page, via the left hand menu. If there are no BHA’s here, then one must be added before you can proceed to the next step. The BHA must also include a bit.
Select the 4 squares beside the appropriate BHA and select the BHA images option
Images can now be uploaded. This can be done individually by selecting the picture icon to the right of each image, or by choosing Select Multiple from the bottom of the dialog.
Images can also be deleted individually or all at the same time via this dialog.
Once an image has been uploaded, a new option will become available at the top right of the picture where the user can identify the picture as a drill bit.
This is important as this dialog is for any relevant BHA pictures and is not exclusively for drill bits.
Once a minimum of 4 pictures have been identified as drill bits, click on Grade Bit at the bottom of the dialog to run the ZerdaLab bit grading feature. Depending on the number of blades, you may require more than 4 oictures to accurately grade the bit.
Wait for the Portal to contact the ZerdaLab server. After a minute or so, the Bit Grade dialog should appear with the results.
The user can then edit the results if they wish.
The Bearing grade will default to Not Applicable.
The output cannot provide the Gauge or Reason POOH results. The user must enter these manually.
Once the user is happy with the bit grade, they should click Accept to save the results.
The results will be saved to the Grade Out property for the bit belonging to the selected BHA.
5.0 – Innova App Interface
The following section details the required steps to grade a bit using the automated feature in the Innova Phone App.
Login to the App using valid login credentials.
Select the desired well from the Wells page by tapping on its name in the list.
Access the Drill Strings page by tapping on the BHA option at the bottom of the screen.
Images can now be uploaded.
This is important as this dialog is for any relevant BHA pictures and is not exclusively for drill bits.
Wait for the App to contact the ZerdaLab server. After a minute or so, the Bit Grade dialog should appear with the results.
The user can then edit the results if they wish.
The Bearing grade will default to Not Applicable.
The Output cannot provide the Gauge or Reason POOH results. The user must enter these manually.
Once the user is happy with the bit grade, they should tap Submit to save the results.
The results will be saved to the Grade Out property for the bit belonging to the selected BHA. To view the bit grading, return to the Drill Strings page and tap on the desired BHA to view its components.
Tap on the Drill Bit component in the list.
Scroll down to the Grade Out field. The bit grading can be edited by tapping on it.
