It is essential that regular mud checks are carried out during drilling operations to ensure that there are no drastic changes in the muds composition which could slow down drilling efficiency or potentially be catastrophic to the integrity of the well.
Oil, water & solid & salinity measurements are carried out by mud engineers regularly to ensure the composition is appropriate for the formation & depth being drilled. The composition of drilling mud can change quickly, affected by a number of factors including cuttings from drilling or fluids seeping in from the surrounding formation. It’s therefore essential that mud engineers can quickly & accurately measure the drilling mud & take corrective action where necessary.
Oil, water, solid & salinity measurements have traditionally been measured via a retort & titration test which involves the use of various chemicals & heating elements. The entire measurement process can take over an hour to complete, & since the accuracy of the measurement process relies on fixed volumes of fluids & chemicals there is the potential for human error, particularly with a titration which relies heavily on the users interpretation.
The MudChecker hand-held analyzer takes a maximum of 10 minutes to carry out a retort & titration equivalent oil, water, solid and salinity measurement. The electronic measurement process means the device is far less susceptible to human error than the traditional retort & titration method and an electronic date & time stamp recorded against each result provides traceability in the event of an audit.
Verification of the MudChecker’s ability to take accurate, repeatable results is essential to validate the device for long term operational success. We carried out a series of experiments to test the devices repeatability when measuring oil, brine, solid & salinity & the devices ability to track changes in composition.
