<br /> 13. Describe Proposed or Completed Operation:Clearly state all pertinent details,including estimated starting date of any proposed work and approximate duration thereof.If
<br /> the proposal is to deepen directionally or recomplete horizontally,give subsurface locations and measured and true vertical depths of all pertinent markers and zones.Attach
<br /> the Bond under which the work will be performed or provide the Bond No.on file with BLMIBIA.Required subsequent reports must be filed within 30 days following
<br /> completion of the involved operations.If the operation results in a multiple completion or recompletion in a new interval,a Form 3160-4 must be filed once testing has been
<br /> completed.Final Abandonment Notices must be filed only after all requirements,including reclamation,have been completed and the operator has determined that the site
<br /> is ready for final inspection.)
<br /> All depths are referenced to GL.The 15H-1 well reached the end of its useful life and has been abandoned.The 7.0"casing was flushed with fresh water
<br /> and cleaned with a 7.0"casing scraper to the top of the 4.5"liner hanger at 1875 feet.A cast iron bridge plug was set at 1872 feet.The 7.0"casing was
<br /> perforated at depths of 1,550, 1,475,500,and 325 feet.Each perforation interval consists of four 0.43'holes at 90 degree phasing and 21.5"of
<br /> penetration. All cement plugs were set using balance method and consisted of 14.2 lb/gal Portland Type I/il cement. Plug 1 was pumped at 1,855 feet
<br /> and consisted of 6.6 cu yds(31.7 bbls, 136.5 sks)with High Early accelerant. Plug 1 was allowed 17.75 hours to set,after which the top of cement was
<br /> tagged at 1,129 feet. Plug 2 was pumped at 1,075 feet and consisted of 7.0 cu yds(33,66 bbls,147 sks)with High Early accelerant. Plug 2 was allowed
<br /> 6.5 hours of set time,before the top of cement was tagged at 326 feet. Plug 3 was pumped from a depth of 290 feet and consisted of 2.5 cu yds(12 bbls,
<br /> 52.5 sks)with High Early accelerant.Cement from Plug 3 reached the surface at the end of pumping and eventually feel back to 73 feet.The 7.0"casing
<br /> was topped of to surface with 0.6 cu yds(2.88 bbls, 12.6 sks)of Portland 1/II cement on 8/18/23. The well was dug out at the surface and the casing cut
<br /> off 3 feet below GL.A plugged and abandoned hole marker was installed per the Natural Soda UIC permit.The calculated volume of the 1,872 feet of 7.0"
<br /> casing is 15.33 cu yds(73.7 bbls,413.9 cu ft).A total of 16.7 cu yds(450.9 cu It,348.6 sks)of cement,8.2%excess,was used to plug and abandon the
<br /> 151-1-1.For additional information please see attached As-Built Plug and Abandonment diagram.
