American Warrior's Glen Marcellus #B-1 well produces from the Shuck Northwest Field located in South Central Kansas. Oil production is from the Chester Sandstone Formation at 6,140 feet. This formation is part of the much larger Mississippian System. Casinghead gas production is used to power the pump jack. Gas pressure is approximately 80 psi.
American Warrior designed and fabricated a 6 gallon by-pass / knockout pot which will serve both for barrel testing and to allow treatment fluids to be introduced into the well annulus without depressurizing the formation and loss of gas. Pump was reported stuck closed and rebuilt on 6/28/2006 due to scale problems.
Due to scaling problems the treatment method will be modified to eliminate a the typical 1 to 2 day soak period as this might allow the scale to reform. The well should be turned back into production after the circulation period with no soak time.
Barrel testing will be done prior to the initial treatment to gather baseline production data. A combination of barrel testing and stock tank gauging will be used to record any changes in oil / water production.
Initial Treatment - Modified Near Wellbore Clean-up: [10/23/2009]
- Pump off well bore fluids / equalize casinghead gas pressure
- Inject 10 gallons of diesel or condensate into the well annulus
- Dose by injecting 50 gallons Wel-Prep into the well annulus [10/23/2009]
- Flush with 1/2 barrel of lease fluids (produced brine or condensate)
- Begin to immediately circulate well bore fluids for 2 days [10/23/2009]
- Turn back into production
- Produce the well and gauge total fluid production for 30 days
- Note and record any general observations or suggestions about how this treatment method might be improved or modified.
Second Treatment - Critical Matrix Stimulation: [01/17/2010]
-
- Pump off well bore fluids / equalize casinghead gas pressure
- Inject 10 gallons of diesel or condensate into the well annulus
- Dose by injecting 25 gallons Wel-Prep into the well annulus
- Flush with 1/2 barrel of lease fluids (produced brine or condensate)
- Begin to immediately circulate well bore fluids for 1 or more days
- Turn back into production
- Produce the well and gauge total fluid production for 30 days
- Note and record any general observations or suggestions about how this treatment method might be improved or modified.
Third treatment - Near Wellbore Clean-up:
Pump off well bore fluids / equalize casinghead gas pressure
Inject 10 gallons of diesel into the well annulus
Dose by injecting 25 gallons Wel-Prep into the well annulus
Flush with 1/2 barrel of lease fluids (produced brine or condensate)
Begin to immediately circulate well bore fluids for 1 or more days
Turn back into production
Produce the well and gauge total fluid production for 30 days
Note and record any general observations or suggestions about how this treatment method might be improved or modified.
NOTE: Flush production typically recovers oil used to create head pressure and oil 'lost' during shut-in.
