Verification of the of the MudChecker drilling mud analysers capabilities and compliance is critical for long term operational success and in-service reliability.
We put the MudChecker to the test in a series of laboratory experiments against samples of oil based drilling mud with known compositions to validate the devices accuracy and performance acumen. Retort and titration testing was also carried out to provide a direct comparison to existing techniques.
A mud sample where the nominal composition was known provided the starting point for the product testing. Recognized quantities of oil, fresh water, brine, barite and bentonite were then added to replicate in-service operations and create a range of different muds with known compositions. Retort and titration testing based on API method 13 B-2 were undertaken at the start and end pints to validate the measurements as the different constituents were added to perturb the sample composition by a fixed amount.
To determine the composition of the starting sample multiple retort, titration, density and MudChecker measurements were taken to identify the characteristics of the starting sample. Figure 2, displayed on the right shows the oil, brine, corrected solids & brine salinity collated from the measurements taken via the MudChecker.
The full abstract provides detailed data and analysis on the MudCheckers accuracy when tested against a variety of oil based muds with known compositions, provides insight into the device’s repeatability when multiple measurements are taken against the same sample and provides and direct comparison to retort & titration measurements.
