Sample Scale Factor Modifier as Per KCL Concentration Change

Mezintel has introduced a sample scale factor modifier tool to respond to changes in KCL concentration within a bitrun.

The starting scale factor was 3.71. Modified scale factors are: 1.75, 1.30, 1.19 within same bitrun. introduced by timestamp.

Typically, a bit run will start with a Gamma scale factor as specified according to drill pipe collar thickness and mud properties. However, as mud KCL concentration changes, the starting Gamma scale factor must change with it.

In Mezintel, just enter the timestamp when KCL concentration changed significantly to warrant scale factor adjustment. Then enter the adjusted scale factor with value-offset (if needed). Forthwith, Mezintel Gamma will correct the Gamma sample values accordingly.

HELPER Tool to Identify TimeStamp Versus BitDepth

Mezintel includes an intuitive TimeStamp selection tool that gives users a TABLE for Timestamp versus Depth correlation to assist with identifying the optimum time for which a Gamma modified scale factor should be introduce within a bitrun.

Note that you are never too late in adding sample modifying scale factor because data is always saved in pristine and raw state, and sample scale factor is only applied when downloading sample data for LAS reports, or for presentation in charts, or for PDF Logs, or for WITSML streaming.

Furthermore, this intra-bitrun sample scale modifier tool works for any sample channel, e.g: Resistivity channels; and not just the Gamma channel.

The following shows an example of Gamma plot where the Gamma scale factor was modified three times as per KCL concentration change events. The second plot shows the Gamma plot after modified scale factors were applied.

Summary:

Do not get caught with distorted Gamma or Resistivity plots, due to impact of KCL concentration change. Mezintel Gamma affords a tool to include scale factor modification, withing a bitrun, for an unlimited number of KCL concentration change events.
