  • Here is a brief explanation of how the tool was planned.
  • Development of a GIS based Chemistry tool to Optimize Produced Water Treatment

    1. 1. DEVELOPMENT OF A GIS BASED TOOL TO OPTIMIZE PRODUCED WATER TREATMENT Ashwin Dhanasekar, Dr. Ken Carlson Dept. of Civil & Environmental Engineering Colorado State University, Fort Collins, CO
    2. 2. INTRODUCTION• Hydraulic Fracturing• Produced Water• Current Scenario• Colorado Energy Water Consortium• GIS Tool• Chemistry Tool• GIS Based Treatment Application
    3. 3. HYDRAULIC FRACTURING
    4. 4. WATER USED FOR DRILLING
    5. 5. PRODUCED WATER• Recoil of the Drilling Process• Frac Flowback• Produced Water• Current Scenario
    6. 6. AREA OF CONCENTRATION
    7. 7. COLORADO ENERGY WATER CONSORTIUM ENVIRONMENTA LOCAL GOV’T L Weld County The Nature Commissioner Conservancy INDUSTRY CONSULTING Noble Energy ENGINEERING CH2M Hill REGIONAL GOV’T COLORADO Western WATER Governor’s INSTITUTE Assoc. Director AGRICULTURE ACADEMIC Former Ag Colorado State Commissioner University
    8. 8. DATA COLLECTION • State Databases Public Data • Public Websites • Industry – Noble Energy Private Data • Other Industries • Government Agencies Common Data • Colorado Oil & Gas Association
    9. 9. QUANTITY ANALYSIS & PREDICTION • Drilling • Completion Water Water Dates Drilled Recompletion Period and Production Volume of Period & Flowback Volume • Frac • Produced Flowback Water
