HOLE CLEANING EFFICIENCY (HCE) 

Quantifying Hole Cleaning Efficiency is arguably one of the most important drilling performance metrics needed to successfully drill a well. 

The use of a Material Mass Balance on all mud components entering and exiting the well is tracked at multiple stations throughout the circulatory system. At each station the mud density, the volume & mass of water, oil and solids are all compensated for gas, compressibility and temperature.

Quantifying HCE has deep roots into the Management of Risk associated to Health, Safety, Environmental and Overall Costs. The real time data used to quantify hole cleaning efficiency also helps reduce the risk of well control incidents, safety and environmental infractions, stuck pipe, casing running issues, poor wellbore placement, the list goes on. Reduce the risk, reduce the costs associated to the risk.

SOLIDS REMOVAL EFFICIENCY (SRE)

Quantifying Solids Removal Efficiency has interrelatedness in just about every workflow on the rig. It’s not only important to quantify but to optimize as it has significant cost implications. 

Solids Removal impacts the amount of dilution required to drill the well, it impacts the volume of waste disposal, it impacts equipment wear and downhole tool failures, it even impacts wellbore placement and production economics. 

Solids Removal has deep roots in the Environmental Social Governance space, specifically in the reduction of Greenhouse Gas Emissions. The cleaner the mud system, the lower volume of waste disposal, fewer trucks hauling waste, fewer GHG emissions. Cleaner mud system also helps reduce diesel consumption via the generators, fewer GHG emissions.
