Wastewater Spill into creek bed.

On August 9, 2017 a report was filed with the state - 
  • "An injection water release occurred at Injection Well Grub #180 of the Grub Rincon Leasse. Approximately 4,200 gallons of injection water released. Two gallons entered a dry creek bed. Cleanup conducted at well and creek bed."

The following blog post is by Anneliese Anderle, a certified Petroleum Geologist and retired state (Division of Oil, Gas and Geothermal Resources (DOGGR)) inspector. 


 

September 11, 2017 - Ventura County
[According to online state records] The well Grub #180 is in the San Miguelito Field, which is just west of the AERA Taylor Lease in the Ventura Avenue Field west of the Ventura River and north of Route 101.
"Grubb" 180 (111-20401) operated by California Resources Corp. is a quite high surface injection pressure water-flood well, at 2400 PSIG in June 2017.  If an injection line at such a high pressure ruptures or at least starts as a pin-hole, considerable substrate material will be flushed, creating a crater.  The very small 10 gallon volume reported on OES-17-5709 strains credulity as a leak this injection line or at the wellhead would be a very large volume before the injection pump trips out due to low line pressure.
It is not uncommon to spill some injection water if the well is being logged with a radioactive wireline tracer, but less than 10 or 15 gallons is routinely lost at the top of the lubricator mast.
The spill volume is obviously approximate, representing 4200 gallons or 100 barrels of fluid.  When injection water spills happen from high pressure injection line ruptures or a well head failure, there is no clean up as the water soaks into the ground or dry creek bottom (the spill location indicates a channel to the Pacific Ocean).  If the injection water is 'dirty', containing Iron Sulfide or fine filtrate, the residue will show.  This is also true of the dissolved salts, which may leave a crust at the spill, particularly if it is contained in a pool.
There may be a follow-up report at the CALEPA spill data base, otherwise the spill report can be found at the DOGGR District 2 office once the investigation is complete.
The DOGGR office will routinely send a field engineer to document the spill, including photos.  It will then be followed up with an investigation and remedy by CRC for the spill occurrence.
