The same relationships built into our tool kits and remote evaluations — run them live, get the band you're in, and know what to do next. Works on the rig, online or off.
Current API RP 13C SRE compares drilled-solids volume removed with excavated hole volume over the same interval. Use a consistent volume basis and assess mud-to-cuttings ratio (MCR) alongside SRE; wet discard volume is not drilled-solids volume.
Cone separation depends on geometry, feed pressure/head, flow and fluid properties. Calculate head from pressure and density, then compare the measured duty with the OEM operating range; head alone does not establish cut size or separation efficiency.
Bowl acceleration is one operating variable. Barite recovery, fines separation and dewatering depend on fluid properties, feed rate, pond depth, differential speed and actual discharge routing; speed alone cannot define the duty.
Solids-control losses are invisible because the system never stops running — the dilution rate just sits quietly higher than it should. Put a number on what restoring efficiency is worth over a section.
Pick a screen by mesh alone and you're guessing. API RP 13C labels a screen through a defined screen-cloth test and conductance, not through field PSD alone. Tell us the section and fluid; get the cut-point priority, the trade-off to watch, and what to read on the deck.
These five run one calculation at a time. The Doctor toolkit links 22 connected modules — diagnosis, what-if and daily reporting — and works offline in five languages. Enter your email to request the field guide and a sample remote-evaluation report.
