🔍 Key Concepts

• Rotary drilling circulation system components and flow path • Function of equipment that physically screens solids using vibrating screens/sieves • Difference between mechanical screening devices and hydrocyclone-type devices like desanders and desilters

💭 Think About

• Which piece of equipment is located first in the solids control line, right after the mud returns from the well to the rig? • Which option specifically relies on vibrating screens or sieves, rather than gravity settling or centrifugal action? • Think about which devices are designed for larger cuttings versus very fine particles—how does that relate to trays with sieves?

✅ Before You Answer

• Confirm which device uses vibrating screens mounted on trays to remove larger drilled cuttings • Confirm which devices (from the other choices) use gravity settling or hydrocyclones instead of screens • Check your drilling mud flow sequence: flowline → first solids control device → other separation stages
