1. Inverted Motors for Drilling Basic Concepts and Design US and International Patented and Patent Pendings Ken Oglesby Impact Technologies LLC PO Box 35505 Tulsa, OK 74153 kdo@impact2u.com

2. Inverted Motors for Drilling Basic Configuration Differences – Conventional Motor Configuration Housing connected to drillstring and does not rotate (connected to motor stator) Shaft internal to housing and rotates (connected to motor rotor). Drilling tool attached to shaft. Fluid flow goes through motor and crosses over into shaft channel before existing Electrical wires cannot go through motor – Basic Inverted Motor Configuration Shaft connected to drillstring and does not rotating (connected to motor stator) Housing rotates (connected to motor rotor) with tool attached Shaft has channels for flow and wires Fluid and wires can enter motor at any point- or not at all

3. IM Basic Inverted Motor Configuration

4. Inverted Motors for Drilling Benefits of IM Configuration Allows use of advanced drilling techniques Ultra high pressure / Abrasives / Acids/ bases MWD (key drilling and directional measurements) and LWD (formation logging measurements) tools in/ at bit Multiple motors (different sizes and rotation direction) on BHA/ drillstring Short lengths of each motor allows ultra-short radius turns

5. Inverted Motor for Drilling Various Types of Inverted Motors

6. Inverted Motors for Drilling Channel(s) in Shaft of IM Motor Fluid/Gas Flow Ultra High Hydraulic Pressure Electrical Wires Optical Wires for uses in Hydraulic/Abrasive/Dir Jetting MWD / LWD (near-bit or in-bit) Improved Hole Cleaning Multiple Motors

7. Inverted Motors for Drilling Other IM Uses Proven Advanced Technology uses High Pressure Hydraulic Jetting Bi-centered Movement for Hole Enlargement Abrasive Jetting (solids added to HP stream) Low Weight on Bit (with above systems) New Technology uses Enhanced Directional Drilling (Offset Hydraulic / Abrasion Jetting) Laser/ Plasma Drilling Clamp-on IM for CTD

8. Inverted Motor Drilling System Long Video HP Jetting & ASJ Multiple motors, step drilling, counter-rotation Jointed or Coiled Tubing Drillstring does not rotate Ultrashort Turns Possible

9. Inverted Motors for Drilling Generalized Electric IM Motor Configuration

11. Conversion Factors Torque- Newton Meters to Foot Pounds – 1 Nm = 0.73756 ft lbs Dimensions- Millimeters to inches – 1 mm = 0.03937 inches Power- Watts to Horsepower – 1 watt = 0.001341 Hp US – 1 KW = 1.341 Hp US – Horse Power = 0.746 Kilowatts – Hp = ft-# torque X rpm /33000

12. List of Acronyms, Abbreviations, Conversions and Equations Power (Horsepower) = Torque(lb-ft) * rpm 5252 Power (Watts) = Torque(lb-ft) * rpm 7.04 Foot-Pound Torque = Newton-Meters Torque * 0.7376
