  1. 1. Experimental Technologies/Research Robert C. Trautz Sr. Project Manager Knowledge Sharing in MVA/MMV Mobile, AL May 17, 2012
  2. 2. Outline •!Comparison of Groundwater Sampling Methodologies –!Collaboration with the US Geological Survey •!Integrated Modular Borehole Monitoring (MBM) System –!Collaboration between SECARB, CO2 Capture Project and Berkeley Lab© 2012 Electric Power Research Institute, Inc. All rights reserved. 2
  3. 3. Groundwater Sampling: Context •!Above zone groundwater USGS photo: Fluid Sampling during Pumping at D9-8#2 monitoring may be used as a compliance tool to detect CO2 leakage •!Samples undergo geo- chemical transformation when collected from deep wells, e.g., –!Exsolution of dissolved gases –!Changes in dissolved CO2 concentrations that control pH –!Exposure to atmosphere causes changes in redox •!Industry needs best available practices for compliance© 2012 Electric Power Research Institute, Inc. All rights reserved. 3
  4. 4. Groundwater Sampling Comparison •!Purpose: –!Compare sampling methods to identify significant differences in groundwater quality results –!Compare costs/benefits of each method •!Scope: Collect and analyze groundwater samples using four artificial lift techniques 1.! N2 gas lift 2.! Pumping 3.! Kuster Sampler (wireline) 4.! U-tube sampler Photo Courtesy of the USGS photo: Fluid Samples from Gas Lift© 2012 Electric Power Research Institute, Inc.

  7. 7. Integrated Modular Borehole Monitoring (MBM) System (Berkeley Lab) •! Purpose: Multi-sensor platform designed for a single-well deployment !! Reservoir pressure and temperature !! 18-level geophones for CO2 imaging !! Distributed Temp. Sensor (DTS) and heater for near-well leak detection !! Distributed fiber optic cable for seismic measurements (Schematic courtesy of Paul Cook, Berkeley Lab) !! U-tube fluid sampler© 2012 Electric Power Research Institute, Inc. All rights reserved. 7
  8. 8. MBM Deployment Geophone Clamping Assembly •!Geophone array (6,000-6,850 ft): three, xyz- comp. and 15, z-comp. phones at 50 ft spacing Flat-pack containing control lines, u-tube sampler, and fiber optic/ •!Bottom hole assembly heater cable, sensor lines (9,384 – 9,797 ft) –!Hydroset II packer –!U-tube –!Overshot –!Slotted tail pipe (structural support for DTS and heater) –!Two quartz P & T gauges Geophone, Mechanical Clamp and Flat Pack© 2012 Electric Power Research Institute, Inc. All rights reserved. 8
  9. 9. Pressure Communication Observed Across Packer Hydroset II Packer •!Packer set at 9,384 ft •!Kill fluid was unloaded from the annulus but … –!Flow continued –!Annulus pressure climbed when shut in •!Pressure response was observed by both gauges below the packer •!Damaged Packer?© 2012 Electric Power Research Institute, Inc.

  12. 12. Well Diagnostics Con’t – Inflow Above Packer Inflow above packer© 2012 Electric Power Research Institute, Inc. All rights reserved. 12
  13. 13. Summary •!DTS and heater were successfully used to pinpoint inflow above the packer –!Packer is set in top of perforations •!Discussed options with State Regulators including removal –!Well has mechanical (pressure) integrity –!Cement bond logs show good cement behind casing –!D-9-8#2 is not permitted for injection –!Completion similar to a production well or MS injector –!Removal and re-deployment would be costly –!Research equipment could be irreparably damaged •!Successful diagnostics saved project $200,000 - $430,000© 2012 Electric Power Research Institute, Inc.

  15. 15. intelligent Distributed Seismic - VSP •! Fiber Optic Cable being the sensor: provides very large receiver array (dense sampling) •! complete wellbore coverage for every source firing •! dynamically change the sensor / antenna length to any value greater than one (1) •! High fold with walk-away / 3-D VSP •! Identification of lateral variations in lithology for Well-Placement and Landing ERD wells •! 3-D Velocity and Anisotropy© 2012 Electric Power Research Institute, Inc. All rights reserved. 15
