3. INTERNSHIP OBJECTIVESIntegrate theory with practice & apply theoretical knowledge in industrial application.Introduce student to work culture and industrial practicesExpose student to potential employersImportance Health, Safety & environment (HSE) at workplaceTo make interns be acquainted with water-based mud systems used in ScomiOiltools in Sudan operations and contribute the company by assisting on-site field engineers.

4. HOST COMPANY PROFILEScomiOiltools (formerly known as KMC Oiltools), a subsidiary of Scomi Group. One of the world’s leading providers of innovative high performance drilling fluids and drilling waste management services.ScomiOiltools had established overseas operations in Sudan in 2003 with GNPOC and in 2005 with WNPOCInvolved in three core division – drilling fluids, drilling waste management and oilfield product distributionWorldwide operations coverage of drilling fluid operations - extends from Asia region to USA

5. DRILLING FLUIDSIntroductionFluids that aid the production and removal of cuttings from the boreholeDiffer widely in their chemical compositions.Also known as mud.

7. DRILLING FLUIDSMud Circulation

8. DRILLING FLUIDSMud ContentFluid Phase (water or oil)Solids (to give desired mud property)Inactive solids – do not react with mud (i.e barite) to give mud weightActive solids – clays that react with the water (i.ebentonite) to give viscosity.Additives (to give desired mud property)Polymers and chemicals to control viscosity, yield point, fluid loss, pH, controls

9. DRILLING FLUIDSMud Types1. WATER BASED MUDContinuous phase is water

10. Main disadvantage – causes shale instability

11. Lower cost

12. Types of WBM used in ScomiOiltools Sudan Operations -

13. Non-inhibitive (gel)

14. Inhibitive (KCl)

15. Polymer (KCl PHPA, KCl silicate)DRILLING FLUIDSMud TypesContinous phase is oil

16. Advantage

17. Does not react with shales

18. Good lubrication to BHA

19. Undamaging mud – very low formation damage if any

20. Excellent wellbore stability

21. Usually used in HTHP wells

22. Disadvantage

23. Environmental impacts (toxic)

24. Much more expensive than WBM

25. Danger threat to rig workers - slippery2. OIL BASED MUD

26. DRILLING FLUIDSChemical & Polymer AdditivesSoda Ash – Hardness reducerSodium Bicarbonate – Hardness & pH reducerCaustic Soda – Alkalinity control (increases pH)Bentonite – ViscosifierPAC-R & PAC-UL (organic polymer) – Viscosity & Fluid loss controlStarch – Fluid loss controlXanthan gum – Viscosifier and LSRV (low shear rate viscosifier)Calcium Carbonate – Bridging & weighting agentBarite – Weighting agent
