  • Advanced Well Construction Techniques Utilizing Solid Expandable Technologies: Extreme Stents for Oil & Gass Wells, pumpsandpipesmdhc

    1. 1. Advanced Well Construction Techniques Utilizing Solid Expandable Technologies (SET®) Extreme Stents for Oil & Gas wells Pumps & Pipes 1 12 Nov 2007 Mark Holland NA Sales Mgr
    2. 2. Overview <ul><li>Intro </li></ul><ul><li>Expandable casing statistics </li></ul><ul><li>Case Histories </li></ul><ul><li>What’s new </li></ul>
    3. 3. On January 10, 1901 the famous Lucas Gusher blew in. Oil sprayed over 100 feet above the derrick for nine days until the well was capped.
    4. 4. Conventional Well Design <ul><li>Several to many casing strings in a “tapered” configuration </li></ul>Each one decreases “diametric efficiency” by ~20%
    5. 5. What and Where is Solid Expandable Technology? (SET®)
    6. 6. Operating Envelope for Expandable Casing <ul><li>Inclination: 100 o from vertical </li></ul><ul><li>Temperature: 400 o F </li></ul><ul><li>Mud Weight: 19.8# / gallon </li></ul><ul><li>Depth: 28,750 ft </li></ul><ul><li>Hydrostatic: 23,300 psi </li></ul><ul><li>Length: 6, 867 ft </li></ul>
    7. 7. Cumulative Installation Footage As of November 10, 2007 798 Installations 100,000 200,000 300,000 400,000 500,000 600,000 700,000 Nov-99 Mar-00 Aug-00 Jan-01 Jun-01 Nov-01 Apr-02 Sep-02 Feb-03 Jul-03 Dec-03 May-04 Oct-04 Mar-05 Aug-05 Dec-05 May-06 Oct-06 Mar-07 Length (in feet) 238,535 m 775,120 ft
    8. 8. 775,000 ft equals … Traveling from Houston to Goliad
    9. 9. Opportunity vs. Need 9-5/8 &quot; 7-5/8 &quot; Decision Point Hole Size Preservation Hole Size Survival Opportunity Need
    10. 10. Economics Planned Expandable Key Offsets Measured Depth 3000 7000 11000 15000 19000 23000 27000 Tech Limit Reduced drilling time from 140 to 48 days Opportunity (planned) Need (contingency)
    11. 11. Case Histories HPHT Well – Deep Shelf GOM UD High Pressure – DW GOM
    12. 12. HP/HT Well in GOM – 20’ Water Depth <ul><li>Trouble Zone </li></ul><ul><li>Major pressure regression - Losses </li></ul><ul><li>Solution </li></ul><ul><li>Installed 9-5/8&quot; x 11-3/4&quot; expandable </li></ul><ul><li>Value </li></ul><ul><li>Drilled and evaluated virgin formation with sufficient hole size </li></ul>
    13. 13. High Pressure Well in GOM – 3400’ Water Depth <ul><li>Trouble Zone </li></ul><ul><li>Low Margin Drilling in a DW GOM well </li></ul><ul><li>Solution </li></ul><ul><li>Installed 7-5/8” x 9-3/8” </li></ul><ul><li>Preserve hole size to TD </li></ul><ul><li>Value </li></ul><ul><li>Drilled and evaluated new formations in a frontier environment </li></ul>
    14. 14. MonoDiameter™ and What is it? <ul><li>The industry demands it: </li></ul><ul><li>More challenging drilling environments </li></ul><ul><li>Current available technology is limited </li></ul><ul><li>Improved ROI </li></ul><ul><li>Advanced well construction </li></ul>
    15. 15. MonoDiameter™ Defined <ul><li>Provide successive uniform ID over multiple liners </li></ul>MonoDiameter ™ 10.4&quot; ID
    16. 16. Successful Field Appraisal Well <ul><li>Enventure was operator </li></ul><ul><ul><li>Safely completed drilling program </li></ul></ul><ul><ul><li>Followed standard operating procedures </li></ul></ul><ul><li>Well information </li></ul><ul><ul><li>Drilled in Oklahoma </li></ul></ul><ul><ul><li>Real-life well </li></ul></ul><ul><ul><li>Completed April 2007 </li></ul></ul><ul><li>Successful installation </li></ul><ul><ul><li>First of its kind </li></ul></ul><ul><ul><li>Continuation possible </li></ul></ul><ul><li>DNV Certification </li></ul>
    17. 17. Classic Vertical Design
    18. 18. Conclusions – What does this mean to us all? <ul><li>ERD applications </li></ul><ul><li>“ One size fits all” </li></ul><ul><li>Reduces the Carbon Footprint of Drilling Ops </li></ul><ul><li>Drill a more efficient well </li></ul><ul><ul><li>Less cuttings, mud, cement, steel, rig size, etc </li></ul></ul><ul><li>Is there a “Depth Limit”? </li></ul>
