The Wilson Unit #1 is a one well lease which historically has produced one barrel of oil and three barrels of water per day. The well was originally drilled in the early 1920's and recompleted in the 1970's. Production is from the Bartlesville Sand formation with a top pay at 814 ft. and bottom at 820 ft. Water produced is pH 6.8 and is a concentrated salt brine with calcium, magnesium, and barium chlorides and a TDS of 60,000. The well has slight paraffin and scale problems, but not severe enough to require hot oil or chemical treatments.
Initial Treatment - Near Well Bore Clean-up: [9/15/2009]
- Pump off well bore fluids
- Inject 5 gallons of diesel into the well annulus
- Inject 15 gallons Wel-Prep into the well annulus
- Flush with 1/2 barrel of lease water
- Shut in for a 48 hour soak
- Circulate well bore fluids for 48 hours
- Turn back into production [9/20/2009]
- Produce the well and gauge total fluid production for two three weeks
Second treatment - Fluid Squeeze: [10/19/2009]
- Pump off well bore fluids
- Dose by injecting 45 gallons Wel-Prep
- Flush with 3 bbls produced oil to produce static head pressure
- Shut in for 2 days
- Turn the well back into production [10/21/2009]
- Produce the well and gauge total fluid production for 30 days / four weeks
NOTE: Three barrels of oil used to flush the treatment fluid into the formation was recovered within two days after turning the well back into production. 3 1/2 barrels produced in 40 hours.
Third treatment - Fluid Squeeze: [12-01-2009]
- Pump off well bore fluids
- Dose by injecting 30 gallons Wel-Prep
- Flush with 1 1/2 bbls produced oil to produce static head pressure
- Shut in for 2 days
- Turn the well back into production [12-03-2009]
- 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
