“Saving lives one drop at a time.” Down-hole Rock Drill

1. “Saving lives one drop at a time.”Down-hole Rock Drill

2. Mission Statement H2Oasis Innovations is proud to support Water4 Foundation in their perpetual journey to find and obtain water in the most remote parts of the world. We at H2Oasis Innovations believe it is a fundamental obligation to assist a neighbor in need, and we will do everything in our power to accomplish this goal.

3. The Water4 Foundation is a public charity based out of Oklahoma City, Oklahoma. • Founded by Dick and Terri • Greenly. • Water4 takes drilling kits overseas and teaches nationals to drill and complete water wells. https://water4.org/about-us/

4. Problem • Consolidated rock layers within the borehole impede the water well drilling system from completion. • Workers are left with either digging out the rock with hand tools or breaking through the layer using a cable tool system. • These methods take days to remove the rock layer before workers can continue drilling.

5. Cable Tool Method A-frame for cable tool method Bulldozer tooth and spike tooth are used to chip away rock layers

6. Objective • Design a rock drilling system for water wells. • Design budget is initially set at $25,000

7. Client Requirements • Must drill through material as dense as dolomite and quartzite • Maximum depth of 150 feet • Time efficient • Easily Operable • Able to be transported in rough terrain. Quartzite 7 Mohs Hardness scale Dolomite 3.5 Mohs hardness scale

8. Constraints • Materials and fluids cannot contaminate the surrounding environment • Non-electrically powered • Limited fluid resources

9. Standards and Regulation for Water Well Construction • The code of practice was established by the Rural Water Supply Network (RWSN). • Intended to be used as the foundation for the development of national protocols for cost-effective water well provision • Ethiopia, Ghana, Nigeria, Niger, Mozambique, Burkina Faso and Zambia are among some who enforced the code.

12. Water4 vs. Competitor Drilling Cost

13. Current Methods Pros • Able to drill efficiently • Use sophisticated equipment • Self-sustaining rigs capable of drilling entire operations

14. Current Methods Cons Too expensive for targeted clients to afford Not able to be transported in rough terrain

15. Terrain Togo, Africa Ghana, Africa

16. ProductsDeepRock Manufacturing-Model M60 Pros Cons Produced exclusively for difficult soils Minimal rock cutting ability • Proven design • Minimal physical requirements • Substantial depth capability • Hydraulic variability

17. Boremaster ZX-1000 Pros Cons Insufficient for rural African terrain Not designed to drill through rock • Easy to maneuver and transport • Inexpensive • Easy operation

18. Patents Coiled Tubing Drilling Rig • Utilizes coiled tubing for down hole drilling • Intricate design for deep well drilling

19. Patents Drilling Machine For Drilling Holes In Rocks • A truck-mounted rock drilling machine for pole holes • Consists of a pivotal boom mounted on the truck bed and a jack hammer like mechanism mounted on the boom • The compressor which operates the jack hammer is mounted on a separate trailer

20. Patents Telescopic Rock Drill Feed • A drill feed mechanism in which a drill motor is reversibly driven along a guide way by a rotatable power screw. • A control circuit includes sensing devices for determining when the mechanism is fully telescoped.

21. Design Analysis • Innovative design • Potential marketability for Design4 • Present demand

22. Design 1: Progressive Cavity Motor with Coiled Tubing • Motor is connected to bit down-hole and provides the rotation needed. • Specifications Weight – 100 lbs. Length – 9 ft. Progressive Cavity Motor

23. Rough Draft Design 1 Coiled tubing is attached to the progressive cavity motor on a swing-set support.

24. Sub-Design 1 • Down-hole Motor with Coiled Tubing Setup with water and air • Featuresa down-hole progressive cavity motor to spin a bit at the rock surface. • Motor is attached to coiled tubing at the top surface. • Water and air is pumped through the tubing to power the motor for drilling.

25. Sub-Design 2 • Down-hole Motor with Coiled Tubing Setup with hydraulic fluid and water. • Features a down-hole progressive cavity motor to spin a bit at the rock surface. • Motor is attached to coiled tubing at the top surface. • Hydraulic fluid is pumped through the tubing to power the motor for drilling while water is used to cool the bit interface.

26. Sub-Design 3 • Down-hole Motor with Coiled Tubing Setup with glycerol and water. • Features a down-hole progressive cavity motor to spin a bit at the rock surface. • Motor is attached to coiled tubing at the top surface. • Water/Glycerol mixture is pumped through the power section for drilling, lubrication, and gel strength.

29. Hydraulic Power developed by the Pump • P = Power (HP) • Q = Flow rate (GPM) • Δp = Pressure differential

30. Flowratevs Pressure for HP

31. Design 2: Traditional Approach • Conventional down-hole stem with motor at surface • Features an engine, pump and motor at the top of the hole. • Motor rotates stem, attached to a bit down-hole

32. Hydraulic Power developed by the Motor P = Power (HP) T = Torque (ft.-lb.) N = Rotational Speed (RPM)

33. General parts needed Drill Bits • Carbide Mills • Standard Reverse clutch • Flat, concave, or reverse bottom • Tapered, step, string or watermelon profiles • Crushed carbide, Star Cut carbide, or carbide inserts • Straight or Twister mill bodies

34. General Parts Needed Cont’d Engine • Briggs and Stratton Horizontal shaft engine • 31 Gross HP

35. Parts for design Tuthill HD 120A Series Eaton 72400 Variable Piston Pump • Flow Rate: 30 Gal/100 Rev • Max Pressure: 450 PSI • Capable of flowing high viscosity fluids • Flow Rate: 47 GPM • Max Pressure: 5000 PSI • Compact size

37. Testing Analysis • Dyno Test • Material Removal Rate • Penetration Rate • Necessary Fluid Properties

38. Factors Affecting Penetration Rate • Formation Characteristics-Compressible strength of formation • Drilling Fluid Properties- Penetration rate tends to decrease with increasing fluid density, viscosity, and solids content. Tends to increase with filtration rate. • Operating Conditions-weight above bit and rotary speed • Bit Tooth Wear- Grinding vs. Cutting • Bit Hydraulics: Jet size and velocity.
