Re: Louisiana: Assumption Parish Bayou Corne Sinkhole 2012 (Update: Crosstex to move butane)
The sinkhole seems to be kind of quiet for the last few days. The only news I've found about it is that another bubble site appeared earlier this week, bringing the total to 13.
*************************
Here's a report detailing all of the actions the various departments are doing to keep on top of the situation
Ramping up operations:
*********************
The companies that are reporting daily to the DNR and their current activity as of their Aug 22/23 reports. They are also doing various monitoring
** Acadian Gas Pipeline – Pontchartrain No 1 (La Serial No 971444)
operating as usual
** Chevron Pipe Line Company
NS1 cavern natural gas
Aug 16 - NS1 Blocked in and isolated; blocking maintains integrity and stability
Aug 17/19 - Preparing to begin water injection into the cavern
Aug 22 - Within 24 hours, begin hydrotesting water supply lines that will be used for injection into the NS1 cavern.
** Crosstex:
Aug 10 - Well # 1: 18,408 bbls of isobutane (moving/emptying as of Aug 10)
Well # 2: 934,893 bbls of normal butane (continuing normal operations)
Aug 19 - Well #1 empty, Well #2: 950,521 bbls of normal butane Movements to the well halted
Aug 23 - well # 1 - 11,767 bbls normal butane, well # 2- 930,390 bbls normal butane... Transferring well # 2 butane to off-site customer and to well # 1.
** Dow:
Aug 10- 23: continuing normal operations
** K/D/S Promex:
Promix operates a total of 5 wells with 3 of the five being used on a daily basis for the storage and withdrawal of produced liquid hydrocarbon products from the fractionation of natural gas liquids. The other two are empty of hydrocarbons, but full of saturated brine water and are continuously monitored.
Plans are to continue injection and withdrawal of products from the 3 active wells. The two inactive wells will remain out of service and full of brine for the foreseeable future
** Occidental Incident:
PB Energy is the onsite Manager of the Occidental Chemical Corp Brine wells at the Napoleonville salt Dome.
Aug 9-20: We are conducting normal operations at the Brine production facility.
** Texas Brine
Surface water/salinity sampling locations
3 maps showing locations of water samples/wells/property lines, air monitoring and the 6 trees they are monitoring in various locations around the sinkhole
Replacing the boom that was lost with the last sinkhole expansion.
Installing tilt meters at 4 locations: 2 on the brine tanks and 2 between the sinkhole and Bayou Corne. see map here http://dnr.louisiana.gov/assets/OC/B...P_08222012.pdf
Wikipedia:A tiltmeter is an instrument designed to measure very small changes from the horizontal level, either on the ground or in structures. [1] A similar term, in less common usage, is the inclinometer. Tiltmeters are used extensively for monitoring volcanoes, the response of dams to filling, the small movements of potential landslides, the orientation and volume of hydraulic fractures, and the response of structures to various influences such as loading and foundation settlement.
**********************************
Texas Brine is really going to incur some steep costs before this is over. Their estimated total cost for drilling to date is $566,661.11 (from the DNR link); plus the money they are giving to assist the evacuees. And now this possible fine. A point to consider with these expenses is...what if Texas Brine is not at fault?

Louisiana Commissioner of Conservation James Welsh announced today that Texas Brine may face fines of up to $5,000 a day, or take further enforcement action, if the company does not indicate its intention to cooperate with the enforcement order issued last week requiring immediate payment of assistance to Bayou Corne residents under an evacuation order, including retroactive payments dating back to the original evacuation order.
