Lab 10 measurement of the oil, water and solid contents of drilling mud sample using retort kit (10 & 50 ml).
- 1. Drilling Engineering-I Pet-E-211L Lab Instructor : Engr. Muhammad Awais Qureshi Department of Petroleum & Gas Engineering 5/5/2021
- 2. Experiment # 10 • Objective: 1) Measurement of the oil, water and solid contents of drilling mud sample using retort kit (10 & 50 ml). 5/5/2021
- 3. Apparatus • Oil and water retort kit 10 mL/ 50mL • 100 mL graduated cylinder • Wetting agent • Steel wool • PPE’s (Personal Protective Equipments) 5/5/2021
- 4. Related Theory • Retort Kit • The Retort provides a method for measuring the percentage (%) of oil and water, and for estimating both suspended and dissolved solids contained in a sample of water-based or oil-based muds and cuttings. 5/5/2021

- 7. Measurement Procedure 1) Lift retort assembly out of the insulator block. 2) Remove the mud sample cup from the retort. 3) Pack the upper chamber with very fine steel wool. 4) Fill mud sample cup with mud and place lid on it allowing excess to escape. 5) Wipe of excess mud and screw mud sample cup into upper chamber. 6) Replace retort in insulator block and put insulating cover in place . 5/5/2021
- 8. 7) Add a drop of wetting agent to graduated cylinder and place under drain of condenser. 8) Turn the heater on. 9) Heat mud sample cup until oil stops coming out or until the pilot light goes off. For diesel oil the time be about 15 min. 10)Read the volume of oil and of water in graduated tube. (Drop of wetting agent ay this time will often improve the meniscal reading easier. 5/5/2021
- 10. Observation and Calculations Oil Volume Collected = X = _________________ ml Water Volume Collected = Y= ______________ ml Total Liquid Volume = TLV = X+Y = _______ ml Solid Volume = (10-(TLV)) = ___________ ml 5/5/2021
- 11. Precautions 1. Avoid contact with Retort Kit Chamber while it is hot. 2. Wear relevant Personal protective equipment. 5/5/2021
- 12. Viva Voce 1. What problems are you likely to encounter during drilling operations if you have a high sand content in your drilling mud? 2. Why we need to know about the composition of drilling mud? 5/5/2021
