2 Before we get started, remember..never upset a Backhoe Operator.

3 ...and above all remember, never ever..upset a Backhoe.

4 Within recent years several new technologies have come along which truly deliver on the promise of: Enhanced Personal Safety, Increased Profitability, and Reduced Operating Costs.

thought unrecoverable and are now major producers.

5 Game changing technology: Horizontal Drilling Horizontal drilling was a real game changer, opening up new and old reserves previously thought unrecoverable and are now major producers. Horizontal drilling helped companies be safer, more profitable and reduce operating costs.

6 Game changing technology: Multi-Stage Fracturing Multi-Stage Fracturing of horizontal formations is a real game changer, enabling companies to produce more energy through the same wellsite. Multi-Stage Fracturing helped companies be safer, more profitable and reduce operating costs.

Game changing technology: Multi-Well Pad Sites By

can reduce distress on surface roads, reduce operator

7 Game changing technology: Multi-Well Pad Sites By drilling several wells on the same pad site companies can reduce distress on surface roads, reduce operator travel, reduce construction costs, and greatly reduce Rig relocation costs. Multi-Well Pad Sites help companies be safer, more profitable and reduce operating costs.

8 Game changing technology: The Wireless Wellhead The Wireless Wellhead is a game changing technology that enables Producers and Operators to bring on wells faster at less cost and at less risk to personnel. Well performance data starts streaming during flowback and throughout the life of the well giving Reservoir Specialists the tools to produce more. The Wireless Wellhead makes life safer, increases profitability, and reduces costs to deploy and maintain remote assets.

9 Wire is expensive to purchase Wire is expensive to install Wire gets stolen Wire gets dug through Wire can be unsafe Wire needs protection Gas Well Deliquification Workshop Wire has it s challenges

10 Wire takes up room Wire gets sabotaged Wire is restrictive Wire requires maintenance Wire can kill Gas Well Deliquification Workshop Wire has it s challenges

11 Wire costs have doubled and doubled again.

12 Ripped from the headlines! Gas Well Deliquification Workshop Wire sometimes disappears

13 Wire is yummy.

14 Qualified Electricians can be hard to find. Non-Qualified

15 Flammable, hazardous gases and fluids are buried in same trench just inches away from a potential source of ignition. Gas Well Deliquification Workshop Current Method Trenching and Backfill More Labor Intensive More Materials Required Scheduling Issues Project Delays Frequent Cost Overruns Heightened Safety Risks

20 Wireless Wellhead Communications Typical multi-well pad

21 Wireless Wellhead Communications Wireless field sensors at well report to base radio: 1. Casing pressures, 2. Tubing pressures and 3. Braden pressures 4. Plunger arrivals

22 Wireless Wellhead Communications Wireless field sensors at separator and vapor recovery unit report to base radio 1. Temperature 2. Level 3. Pressure

23 Wireless Wellhead Communications Wireless field sensors on oil and water tanks report to base radio: 1. Water tank levels 2. Oil tank levels

24 Wireless Wellhead Communications All field devices wirelessly send data to the base radio antenna located at the site rtu.

25 Wireless Wellhead Communications Field data is transmitted to the site rtu

26 Wireless Wellhead Communications The well site rtu sends all field data up to the antenna located atop the tower.

27 Wireless Wellhead Communications Long-haul radio sends all field data from the well site rtu to far away field or corporate offices

28 Wireless Wellhead Communications All field data is then forwarded on to corporate offices for data processing, engineering, accounting, management, operations, etc.

30 Single panel manages all pad instruments. Notice how few number of wires landed near zero instrument commissioning.

31 Original pilot well drilled to test the formation and is networked wirelessly with the wells below, without line of sight.

32 Non-Line of site install to four tanks measuring interface, level and temperature.

$Once the rig slides to drill the next well, the frac head is instrumented allowing measurement of gas during flow back while providing$

33 Once the rig slides to drill the next well, the frac head is instrumented allowing measurement of gas during flow back while providing tubing and casing pressures to the drilling engineers for added value far beyond the norm. The pad is Div 1 until the rig leaves the site.

34 SIMOP: Simultaneous Operations Drill Here Frac Here Flow-Back Here Produce Here Wireless makes SIMOPS safer, more productive, and more economical.

35 Once completed the arrival sensor is installed.

36 When all wells are completed, the pad is left nice and clean having had zero trenching to the wellheads. Later, when a well gets a work over, there is high probability the instrumentation will not be damaged improving the cost of ownership for this producer.

37 The Wireless Wellhead Application: Rapid deployment for new and retrofit applications Plunger Arrival sensor, Pressure Sensor for Tubing, Casing and Braden Head Temperature, sand erosion and valve positioning can be added

38 The Wireless Well - Single Well Solution

39 The Wireless Well Multi Well Solution

40 The Wireless Well Reuses existing gear All EFM devices are welcome No Charts, please.

41 The Wireless Well Smaller, More Powerful Managing a multi-well pad just got a whole lot safer, smaller and less costly

42 The Wireless Wellhead Equipment used: Class 1 Div 1, wireless sensors self-contained, battery-powered Pushbutton LCD local display on the sensor -40F to +185 F Base radio supports up to 100 field sensors Range: 2500 ft Range (optional): One Mile (external antenna) Long battery life, 5-15 years Base Radio, Class 1 Div 2
