The Casebeer is an old one well lease originally completed in the early 1920's and recompleted on 9/26/1968.  4 1/2 inch casing was run to 820 ft. +- and the well was perforated with 32 shots between 762 and 776 feet.  This well is located at the edge of the old East Unit waterflood that was conducted from the mid-1950's until late 1960's.  It has been affected by near by water injection activity though there is no injector on the Casebeer lease.  Oil production is from the Bartlesville Sand formation and has historically run about one barrel per day.  The produced waters are pH 6.8 and TDS of 32,000.  The Casebeer well pumps into a separate tank so accurate production measurements can taken over the course of this single well project.

 

Initial Treatment - Near Wellbore Clean-up: [4/09/2010]

  • Pump off well bore fluids
  • Inject 10 gallons of diesel into the well annulus
  • Dose by injecting 30 gallons MEOR treatment fluid into the well annulus [4/09/2010]
  • Flush with 1/2 barrel of lease water (used 10 gallons lease water due to low static fluid level)
  • Shut in for a 12 to 24 hour soak
  • Circulate well bore fluids for 1 to 2 days
  • Turn back into production [4/12/2010]
  • Produce the well and gauge total fluid production for two three weeks
    • Second Treatment - Near Wellbore Clean-up:

  • Pump off well bore fluids
  • Inject 15 gallons MEOR treatment fluid (used 30 gallons MEOR treatment fluid) [5/25/2010]
  • Flush with 1/2 barrel of lease water (used 10 gallons lease water due to low static fluid level)
  • Shut in and soak for a 12 to 24 hours
  • Circulate well bore fluids for 1 to 2 days
  • Turn back into production [5/28/2010]
  • Produce the well and gauge total fluid production for 30 days / four weeks

    • Third treatment - Near Wellbore Clean-up:

  • Pump off well bore fluids
  • Inject 15 gallons Wel-Prep
  • Flush with 1/2 barrel of lease water
  • Shut in and soak for a 12 to 24 hours
  • Circulate well bore fluids for 1 to 2 days
  • Turn back into production
  • Produce the well and gauge total fluid production for 30 days / four weeks

NOTE: Flush production typically recovers oil used to create head pressure and oil 'lost' during shut-in.
