Hybrid Mud LoggingA Surface Measurement While Drilling™ Service

It is a surprise to no one that our industry is challenged by capital efficiency and return on investment. The returns to date are not acceptable to either the private or public investors.

We have a solution …

Diversified Well Logging is acutely aware of the need to improve our collective capital efficiency. The investor community expects greater return on investment whether it be public or private. This has forced us to evolve and adapt to a more efficient state.

Our evolution has led us to review and renew the traditional mud-logging service in a way that allows improved efficiency from drilling to completions with of course capital efficiency. We believe our service solutions will transform the Unconventional World by allowing every well to have full formation evaluation in realtime. More data, more knowledge more certainty …

Hybrid Mud LoggingA Surface Measurement While Drilling™ Service

Hybrid Mud Logging dispenses with the subjectivity of traditional services. We use on-site, real-time XRF analysis of

the drilled cuttings to give quantitative rock evaluation. Our process boasts rigorous laboratory grade QAQC on elemental

data that is delivered every 28 minutes.

Daily deliverables include the full suite of major and trace elements and field logs with modelled mineralogy, lithology,

TOC, and elemental gamma ray (U+Th+K).

Realtime data is used to:• Geo ‘chemo’ steer• Optimize landing targets• Avoid geological hazards• Avoid drilling dysfunction• Reduce NPT

End of well deliverables include estimated geo-mechanical properties for completions optimization and a chemo- stratigraphic report and interpretation.

Example HML Realtime Logs

Benefits and Applications:❖ Raw data source available on every well❖ No gaps in geological knowledge ever❖ No interference with rig operations❖ Works when downhole technology fails❖ Cost effective with value more than added❖ Realtime geological/geochemical analysis❖ Quantitative information, not subjective❖ Elemental data will increase geocertainty

❖ Chemostratigraphy❖ Geopositioning – chemosteering❖ Modelled mineralogy/lithology❖ Depositional environments❖ Proxies for TOC❖ Chemical gamma ray❖ Sample depth verification

❖ Geomechanical property modelling❖ Rock density and porosity modelling❖ Problem formation recognition❖ Well to well and field correlation❖ Input for completions strategies

Hybrid Mud Logging will transform your view of formation evaluation with its high-tech low-cost, high-value, low risk information that you would otherwise lose unless samples were expensively processed in a laboratory, running the risks associated with exchange of custodianship of the samples. Also, you would not have the high level of near real time QAQC that Diversified Well Logging applies to ensure that the samples are collected on depth and are representative of the interval drilled.

We will be happy to visit and discuss how our evolution in services can improve your drilling, completion and production economics.
