WITS Simulator for Drilling Depth Data

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.

Printing a Select Set of Test Rows

Once the reviewer approves test results in BreakTest, signed test reports of them are automatically generated as PDF files, and archived. 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.

Working on a Select Set of Test Rows

Working with Select Rows
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.

WITS Format as used by Mezintel MWD Products

  Download as Document

Mezintel Depth Tracker streams out ASCII data every 4 seconds via a 9-pin RS-232 male serial port. This data is in WITS format.

WITS (Wellsite Information Transfer Specification) is a 20 year old worldwide oil and gas industry standard that specifies how to format text-based (ASCII) drilling data for transmission between two devices connected by serial ports (RS-232) or by an Ethernet link.

Are Your COM Ports Communicating Accurately?

Are your COM ports swapped?

Mezintel Gamma has a debug window which is commonly used for diagnosing serial port communication issues. One of our customers suggested that this feature would be even more useful if it can be accessed before actually loading a gamma job — instead of only from within a job.
Good idea! So we implemented his suggestion…[1]

3 Ways to Specify Gamma Scale Factor

You can specify a gamma scale factor for each bit run in Mezintel Gamma (version 22.00.061 [1]) using a new built-in tool that helps you derive scale factors.
You can enter a scaling factor if you know it, otherwise, if you are unsure then you can calculate or find it from the Bit Runs window:

  • In the Scale section under the bit run you want, double-click the value box for Gamma Scale Factor
    The Get Scale Factor window opens

You may also click the button to open up Get Scale Factor window.

3 New Methods of Editing Gamma, ROP & Other Samples

In Mezintel Gamma, samples points logged when the drill bit is ‘off-bottom’ are not shown on the plot. This is useful because it allows you to safely remove points from the plot by manually setting them to be off-bottom. This hides the points rather than delete them. The hidden points can be revealed again by reverting them back to be ‘on-bottom’.

How to Organize WITS Data to Send to EDR Provider

Mezintel Gamma continuously sends out data to depth tracking EDR providers such as Pason and RigSense (NOV).

On a regular basis, about every 5 seconds, WITS data packets are sent out as several lines of plain text (ASCII) that are usually comprised of Toolface, Surveys, and Gamma data.
As of version 22.00.031 [1], you have more control over the structure of the data packet.

An example of a packet of lines of WITS data.
Notice that a packet of WITS data starts with the symbols  && and  ends with the symbol  !!

Handling Data Gaps in your Gamma Log Plots

Closing Gaps on Log PlotAs you know, sometimes MWD sample data may go missing for an extended interval of time while drilling continues. In such cases, there is a gap in the sample plot for the depth interval where data went missing.

Up until now Mezintel Gamma used to fill-in (or close) the gap with a straight line. However, some users wanted to control whether or not to show such gaps, so we have provided you with a new option to do just that.

Renew Database to Regain Performance

Slow Performance Due to Accumulation of Jobs (more than 5 jobs)

Depending on your computer’s specs, Mezintel Gamma can start to run slow if you have accumulated about 5 or more jobs in addition to the default job templates. Some processes may even fail to complete when you have too many jobs. For example:

  • Adding a new job may fail to complete
  • Saving tie-in for the Survey Table may return an error
  • Adding a new bit run may fail to complete

Run Program as Administrator

In order to successfully run a Mezintel program, you must run it as administrator. Mezintel software that is not running as administrator will encounter errors as some point of being used.

If the UAC dialog does not pop up when you try to run a Mezintel program, then it is not set to run as administrator.

User Account Control (UAC) pop-up dialog

When you try to run a Mezintel program as administrator, the User Account Control (UAC) dialog will pop-up by default.[1]
