The MudChecker drilling fluid analyser is an accurate, fast and safe alternative to traditional retort and titration testing for measuring the oil, water, solid and salinity composition of drilling fluids.
Field trials have indicated that its use can provide fluid analysis up to six times faster than traditional methods such as retort, producing consistently accurate measurement data.
Traditionally, the oil, water and solid content of drilling mud has been measured out using a retort oven, which can reach temperatures of up to 1000°F (537°C). A measured amount of drilling fluid is placed into a retort chamber and heated until the liquid inside has evaporated leaving just the solids. The oil and water passes through a condenser before moving down a receiver tube for collection in a measuring cylinder to be measured once all liquid has condensed.
However, this approach can potentially be hazardous to the operator:
The extremely high temperatures required to carry out testing present a significant burn risk
Noxious fumes often escape from the retort oven via the seals, putting operators at risk of inhalation as well as potentially skewing readings
The mix of fluids and mains electricity presents a risk of electric shock
Retort and titration measurements can also be relatively imprecise when compared to the MudChecker – inconsistent practises mean results can vary between operators and there is always the increased chance for human error.

The MudChecker empowers engineers with the ability to safely log oil, water, solid and salinity content, oil/water ratio (OWR), oil/brine ratio (OBR) and water-phase salinity measurements in minutes while eliminating the risk of burns, electric shock and inhalation of noxious fumes.
The compact, easy to use and reliable handheld device takes only minutes to complete a full oil, water, solid and salinity measurement on a drilling fluid sample (a comparable retort and titration test can take up to an hour), delivering a host of significant cost and time saving benefits in the process.
Frequent testing is feasible, particularly useful for kick detection or when drilling through complex formations when there is a greater chance of wellbore collapse, reducing the incidence of tool loss and NPT.
MudChecker data is logged with an electronic date and time stamp, avoiding any requirement for results to be recorded manually. This ensures that the data from every well is automatically and correctly recorded, enabling drilling engineers to show traceability in the event of an audit.
The data captured can be quickly up-loaded via a USB interface to the supporting MudChecker software programme and can be exported either as an individual CSV file or as a batch download, providing engineers with an efficient method of sharing results.
