Mezintel Gamma features three LWD log header styles with variation in format, bit run holding capacity, and content (e.g. emphasis on either casings info or mud properties).
A brief summary of these three headers is as follows:
Basic header for logs with 6 bit runs maximum.
The standard header is a brief, suitable for short jobs with a maximum of six bit runs. This header includes all baseline info for an MWD/LWD drilling job as shown here.

In BreakTest’s field density form, applying a proctor (from the Proctor lookup list) to a test results row automatically adds a summary of that proctor to the “Soils Description” list on the form. With this in mind, consider a scenario where a proctor referenced in the test results table is missing it’s corresponding summary on the soils description list, or vice-versa.
Proctor data in row #3 has a matching summary “Description B – 770…”
Proctor data in rows #1 & #2 (1500…) have no matching summary, and “Description A -Edited Proctor – 1700…” has no matching proctor data on the results table. What is going on here?
You can connect Mezintel Gamma to EDR depth tracking systems or MWD decoding systems via two modes:
The “Conductivity Deep” plot is derived from the “Res Deep” using (1/Resistivity Deep) * 1000
Recommended: First read a brief background and the benefits of handling IFR surveys in Mezintel Gamma.
Exporting surveys for IFR correction is now even simpler in Mezintel Gamma.
As of version 22.20.129, an IFR Express Export feature combines 3 steps of the export process into one:

The job templates in Mezintel Gamma software are preconfigured to understand appropriate data formats for each MWD platform / system.
So for example, if you choose the XXT Template then your job will only understand incoming MWD data in the form Tag data (i.e. qTalk):
Gamma = Value
This configuration is correct if your Mezintel Gamma PC is receiving data directly from the XXT device, but if the data is coming from an XXT PC then that data is actually WITS data.

In-Field Referencing (IFR) technology has been applied in directional drilling since at least the early 2000s. Being particularly useful for drilling tightly spaced lateral wellbores, there’s a been a recent surge in demand for this technology, hence requiring more MWD service providers to work with IFR surveys.
IFR surveys has been supported in Mezintel Gamma logging software since 2013, so customers have been able to handle this demand fine. And with increased usage came requests for features and improvements. This article provides an overview of these improvements, but before doing so… what are IFR surveys?

MWD operators often need to match surveys to particular points in a run. A common example of this is during ‘check survey’, which is recommended to be done near the last MWD survey on the previous run. For check survey, finding the last survey on the previous run is fairly straightforward since that survey is probably the very last survey done.
But how about when you need to identify survey locations beyond that, on preceding runs?

The proctor method Moisture-Density Relationship test is now available in BreakTest.
It features a worksheet for the lab measurements, a proctor curve fit tool, and the PDF report which is delivered to the customer.
This proctor test module is based on ASTM698 and ASTM D1557 specification.
As with all e-forms in BreakTest, the proctor test form is auto-filled with its project info as predefined.
Also, repeating test data (e.g. Volume and Weight of Mold) is auto-filled, and derived data (e.g. Wet and Dry Densities) are auto-calculated on the form.

Power outage incidents, while rare, do occur causing interruption of drilling rig sites operations and services. Mezintel Depth tracking systems have been subject to such scenarios resulting in lost connectivity and lost calibration.
However, once power returns, there is a way to quickly recover saved calibration table and Here’s how to do that:
STEP 1: Wait for power to re-turn
Once power returns, be sure that the PC can connect to the Depth Tracking System. Once connected verify that the calibration status says ‘Not Calibrated’. See Fig 1.
In LabVIEW the Enter Key Does Not Navigate to Next Data Entry Box
<Tab KEY> vs <Enter Key> Behavior in LabVIEW Forms
In a LabVIEW data entry form, pressing the <Tab Key> causes cursor navigation to next data entry box. However, pressing the <ENTER Key> on same data box only finishes data entry, and does not move the cursor to the next data entry input box. Why is this so?

An E-Signature stands for: Electronic Signature, and it is an image file of one’s signature that shows up on BreakTest reports after clicking the ‘Reviewed By’ check box. A user must have signatory rights for the ‘Reviewed by’ check box to appear.
An example of an electronic signature is the one shown below

Mezintel Gamma has new tools and features for ECD Calculation!
Illustrated below, are the new features and tools to help you get the job done:
This new tool will allow you to generate the exact values that you need to show in the Mezintel Gamma program. This tool can be used in the shop to test ECD calculation without having the decoder or depth tracking system attached.
The below screen shot illustrates how to deploy this tool. After the window opens, you can send any data that you want to Mezintel Gamma software.

With Mezintel Gamma version 22.33.128, users have access to a utility for auto printing reports that enables the input of default minor and major increments. Please note that minor and major increments must be inputted and saved with each new job. The below figure demonstrates utilization of this utility to input default minor and major increments for a job.
Alternatively, this can also be achieved utilizing manual printing.
Mezintel Gamma can automatically generate and email predefined MWD reports — a collection that includes
Often MWD operators and tool engineers need to simulate WITS data for depth. Depth simulation may be needed for training or shop testing where a depth tracking system (DTS) is not available, or for troubleshooting communication with a present DTS or EDR.
Mezintel Gamma software offers in-app simulation for both MWD and depth data, and this feature may suffice for training and testing purposes. However, how about in certain testing or troubleshooting scenarios when there’s need to simulate data as well as its transmission via a communications port — as would be with a depth tracking system or EDR?
In such cases, a dedicated WITS simulator application is very useful.

The Queued State Machine -Producer Consumer Architecture; abbreviated in this article as QSM –PC is one essential architecture that significantly facilitates the programming of mid-sized to advanced LabVIEW –based projects that constitute 100 or more VIs. In light of the intermediate to advanced nature of the objects that make up the QSM –PC architecture, taking full advantage of this design template requires detailed knowledge of the ‘why’ and ‘how’ of the various design aspects that characterizes this template. This article defines, illustrates, and describes at length the various elements of the QSM –PC architecture.

While drilling, you may not want to log bad values for a particular sample (e.g. points that are too high or too low). In Mezintel Gamma (version 22.17.127 [1]), you can filter out such unwanted values from being logged while drilling.

Once the reviewer approves test results in BreakTest, signing the test reports automatically archives them as PDF files. These PDF reports are snapshots of the e-form as it was when it was signed, and are ready to be emailed to the client.
For field density tests however, there may be times when you are required to provide your client with only a select set of the test rows on the report. You can do this by selecting the rows you want, and printing only those.

In BreakTest, concrete and soils test results are recorded on a long running table list on their e-forms (the list is broken up to fit letter-size pages for reporting). This continuous list simplifies managing the test results.
However, the list can get quite long for field density tests, and there are times when you need to work on certain field density test rows, and skip others. For example, you may need to assign proctors to only a set of applicable rows. Or if you’re approving the test results, you may need to skip certain rows due to inaccurate information. More purposes for this capability follows later in this article.

In the field of materials testing, by signing a test report the signatory is saying that it is okay to archive and send the test results to stakeholders. In addition to placing the signature on the form, digital signing should do more to make any subsequent authorized tasks as seamless as possible. This means taking advantage of the computer to boost productivity by:
In drilling, there are two are two main ways to interpret the rate of penetration (ROP): Instantaneous and Average. Here are good definitions of the two:
Instantaneous ROP is measured over a finite time or distance, while drilling is still in progress. It gives a snapshot perspective of how a particular formation is being drilled or how the drilling system is functioning under specific operational conditions.
Average ROP is measured over the total interval drilled by a respective BHA from trip-in-hole (TIH) to pull-out-of-hole (POOH).
— G. Mensa-Wilmot and Y. Harjadi
Average ROP is important because it’s a key factor to consider when discussing drilling efficiency, plus it produces a cleaner plot than instantaneous ROP.
Averaging points produces a cleaner plot.
