Mudlogging Cabin Overview


DHI DrillSense Mudlogging Unit is certified by the American Bureau of Shipping (ABS) to Class1, Division II and is suitable for use in both offshore and onshore rigs. The cabin is de-signed and manufactured in Singapore, and all hardware and software are thoroughly tested by our team of highly qualified Manufacturing / Service Engineers before mudlogging unit deployment.


The heart of DHI Logging Mudlogging Unit is the DrillSense Data Acquisition System. Our highly trained rig-site geologists and engineers use the powerful and proven DrillSense software to acquire and store lithological data that is combined with engineering data collected from surface sensors to provide integrated formation evaluation, monitoring of drilling performance and operational safety. We also cater a separate work area for the company geologist in our spacious cabin.
