2 Chemical expense management is important, and frustrating It is often the #2 item on your LOE Necessary and critical maintenance expense Invoice amounts are unpredictable Very little audit trail data How many wells over & under injected? Flipping your provider only provides temporary relief 2015 Gas Well Deliquification Workshop Denver, Colorado 2

3 The Problem: Lack of control 2015 Gas Well Deliquification Workshop Denver, Colorado 3

4 The Problem: Lack of control 6 Days of 3 Minute Data ; Quarts of Chemical Dispensed per Minute 2015 Gas Well Deliquification Workshop Denver, Colorado 4

5 The Problem: Lack of control 5 Days of 1 Minute Data ; Quarts of Chemical Dispensed per Minute 2015 Gas Well Deliquification Workshop Denver, Colorado 5

6 The Problem: Lack of control 5 Days of 1 Minute Data ; Quarts of Chemical Dispensed per Minute 2015 Gas Well Deliquification Workshop Denver, Colorado 6

7 The Problem: Lack of control 2015 Gas Well Deliquification Workshop Denver, Colorado 7

8 Why is it out of control? Variables Well working pressures Chemical viscosities Pump performance characteristics Power supply Human intervention and calibration processes Visibility Periodic eye test No real time data Periodic well test data 2015 Gas Well Deliquification Workshop Denver, Colorado 8

9 How do we control and optimize? You can t control what you don t measure Obtain INFORMATION SCADA Real time data Remote control Local algorithms Alerts and Alarms 2015 Gas Well Deliquification Workshop Denver, Colorado 9

10 Can we afford automation? Typical paybacks occur well within the warranty period of the equipment Direct savings in chemical expense Indirect savings / gains in the effectiveness of your chemical program Cost of insufficient maintenance Lost production The cost of the intervention Can you afford not to automate? 2015 Gas Well Deliquification Workshop Denver, Colorado 10

11 What is the solution? RTUs and Sensors Telemetry = Remote Control Logical algorithms and calibration Sensors and switches Cost per well ranges $2- $8K Variability can be significantly reduced 2015 Gas Well Deliquification Workshop Denver, Colorado 11

12 A better way Pad Injection Controller with Manifold 1 Pump, radio, antenna Volume measurement Flow verification At least 20% lower cost than 10 wells X $6K per well Less mechanical equipment to manage 2015 Gas Well Deliquification Workshop Denver, Colorado 12

14 Results : 5 Days of 1 Minute Data ; Quarts of Chemical Dispensed per Minute 2015 Gas Well Deliquification Workshop Denver, Colorado 14

15 Significant reduction in variability Dosing what the doctor prescribed : 5-8X accuracy improvement Better cause and effect correlation Control of #2 LOE line item 2015 Gas Well Deliquification Workshop Denver, Colorado 15
