2 New Hardware/Software Platform Allows Remote Asset Monitoring In the past an operator was required to be at the wellsite to perform tests with the Wireless Well Analyzer System and his Laptop. Now can schedule unattended fluid level, dynamometer, pressure, and power acquisitions test. Using internet or cell phone access any well anywhere in the world can be monitored in detail with high speed and high resolution wireless sensor data. Schedule time, frequency and sampling speed to monitor a well for an extended time Schedule can be changed and data can be remotely retrieved without requiring the operator to make a trip to the wellsite to retrieve and view the acquired well data. 2

3 Operator at the Well Using Current System 3

4 Laptop at the Well Sets Up using WiFi Hotspot then Leaves Unattended 4

5 New Hardware/Software Platform Well anywhere in the world can be optimized/monitored by Operator 5

6 Any Well Anywhere in the World can be Analyzed & Monitored Remotely Communication thru Internet Local internet access at the well or Cellular MODEM to Cloud Laptop with Internet Connection Same data acquisition available to user at the remote laptop and the well can be monitored in detail with high speed and high resolution wireless sensor data. 6

7 Data Pass thru Secure Central Server User authentication and permissions management 1 2 Secure Central Server 3 4 7

8 Webpage Interface for Quick Views of Field System Status and Vitals Office System Central Server Map View Tabular View 8

9 Setup Wireless Sensors to Perform Fluid Level & Dynamometer Acquisition 9

10 Schedule Liquid Level Start End Control Acoustic Trace and Motor Valve Timing Shot Frequency 10

11 Schedule Test with Dynamometer, Power and Pressure Start End Control Dyno Acquisition Length Dyno Frequency 11

12 50K Load Cell Remote Asset Monitor Test on Well on 11/22/2018 A. Wireless Fluid Level a. Acoustic b. 5 second Casing Pressure Buildup dp/dt Steps B. 60 HZ Wireless Pressure Transducer connected to the Casing Annulus C. 60 HZ Dynamometer Acquisition and Motor Power Acquisition Remote Asset Monitor Pressure Transducer Gas Gun 12

13 When Shooting a Fluid Level Should 1 st Close Then Open the Casing Valve 13

14 Wireless Pressure Transducer connected to the Casing Annulus, Acquiring Casing Pressure Simultaneously with Dynamometer Load and Position, plus Motor Power, Amps and Volts at 60 HZ. Normally Wireless Pressure Transducer would be connected to the tubing/not casing. Electronic Actuated Motor Valve controlled by RAM Wireless Pressure Transducer 14

15 Fluid Level Shot acquired at 11/22/ :27:32 down casing. Fluid Level Close to Pump Intake 15

16 Since Motor Valve is Closed then the Casing Pressure Builds Up After LL Shot 16

17 Simultaneous Dynamometer Card Acquisition Referenced to Clock Time Stroke 02:27:32 PM with the yellow dot on the wireless pressure sensors positioned on the pressure spike created by firing the wireless gas 02:27:32 PM. 17

18 Compare Pressure Acquisitions Why do 5 second casing pressure measurements jump around? 18

19 Scheduled Tests Downloaded to Computer 19

20 Examine Fluid Level and Dyno 20

21 Why is One Stroke Different from the Rest 21

22 Summary New platform automatically acquires data without requiring an operator to be present at the wellsite and allows the data to be remotely collected. Operator can create/modify remotely the acquisition schedule to acquire data periodically for an extended period of time or acquire a test on demand. At the well or through the cloud from any location in the world the operator can troubleshoot and analyze the performance of his well. 22
