Mud logging is the process of monitoring drilling fluid bought to the surface during the drilling process. Mud logs are used to track the composition of the drilling fluids and sediment that is bought to the surface. This is essential in preventative maintenance whilst drilling and provides the drill operator with valuable insight into the lithology of the borehole.
This information can be used to determine whether fluid is being lost to the formation so that the composition of the mud can be maintained, ultimately leading to safer, more efficient drilling, reducing the risk of expensive non-production time. Regular mud logs are particularly valuable when drilling through complexed formations where the risk of wellbore collapse is greater.
The MudChecker unit by Salunda is provided with accompanying mud logging software where the composition of oil, water and solids within the drilling fluid can be stored as well as other useful metrics such as the density and salinity of the fluid.
Once installed the user will be navigated to the MudChecker home screen, this is where results will be imported from your MudChecker device. Once the device is connected via the USB provided historic results will automatically be imported from the device into the mud logging software.
Historic records can be easily accessed via the record list on the left-hand side of the interface. This provides a full break down of the composition percentage of oil, water and solids within the drilling fluid and provides the user with both an Oil Brine Ratio (OBR) and the Oil Water Ratio (OWR).
Salinity and density values of the drilling fluid can also be viewed from this page. If running the device in known salinity mode, these values will be taken from those entered on the setup screen. If the device is running in measured salinity mode results will be determined via the MudChecker salinity test *only available on the MudChecker ES.
Mud logs can then be downloaded either individually or batch downloaded in CSV format for formal record keeping and further analysis.
The MudChecker settings can be adjusted from the Setup screen, you can navigate to the Setup screen by simply clicking the Setup button on the top right-hand side of the home screen.
The setup screen can be used to enter the mud density; this will be pre-populated but can be adjusted to account for different types of mud.
The salinity of the mud can also be inputted on the setup screen – alternatively this value can be measured using the MudChecker ES version of the product.
Verbose mode can be disabled within the setup screen to provide a more streamlined version of the testing process to allow for more efficient testing.
Historic records stored on the device can also be deleted from the setup screen.
The MudChecker mud logging software provides a comprehensive mud log of oil, water and solid percentage within a user-friendly interface allowing for more frequent test and analysis of drilling fluids.
