Evacuations in South Shreveport around well site.-UPDATES

CADDO PARISH, LA (KSLA) -The Caddo Parish Sheriff's Office reports about 25 homes in south Caddo Parish were evacuated as a precaution Monday morning, after gas vapors were detected at a well site.

Deputies say that vapors were first detected at the drilling rig near the 11,000 block of Norris Ferry Road around 8 p.m. Sunday night. The situation stabilized, but vapors reappeared around 4 a.m. today.

Initially, only a few residents within a 100-yard radius of the well were evacuated, but that area was soon expanded. Roads currently closed include Cypress Garden, Willow Ridge, Debroeck, and Norris Ferry south of Southern Trace.

 

Go to KSLA 12 for the latest updates.

 

*Cement crews have controlled the pressure of the well in progress

 

**The new and latest concerns stem from the fact that the local aquifer has tested positive for natural gas contamination.

 

Looks like this deal might wind up costing EXCO a little bit of money.

It is my understanding that the Surface Casing on the well being drilled was not yet in place, only the conductor. It is also my understanding that the nearby well on the same pad has not been perferated or fraced.

Baron,

I think the problem is Ser# 237795 LCV RA SU115;DEBROECK 33 #1 casing leaking. This well has been shut in, but at where in the casing? EXCO needs to look at this well, as it may be where the gas at the 1200 ft level on well ser# 241116 may be coming from. Put a packer just above the preparations in Ser# 237795.

Why would you say that? No one is more pro HS drilling than I am, nothing could possibly be worse than for somthing like this to happen and give our irresponsible media and enemies of drilling a soapbox. Nothing hard to understand about that. It's a shame in all aspects.

I believe it may be premature to call Exco irresponsible until it is conclusively determined what exactly happened.

You may be very right Spring, and I will retract and apologize if I am wrong. It looks like it wasn't a casing problem. The questions that will arise will be troublesome for EXCO. Why did they drill to 1200 feet before setting casing? This may be routine as of now but it won't be for long. You are drilling well below the water table and capable of hitting gas pockets in the Nacatoch and other shallow formations. Which may be what happened in this scenario.

CMK,

I think it is common practice to set 10 3/4" casing @ 1800 ft.

This will be an isolated incidence then.

Ah, Jay,

I remember what company...

FYI, Thank you for your insights and the direction you have helped GHS take. We all owe you a great deal. Have a good one.

How could one detect NG fumes? Does it have a particular smell? I thought the odor was put in the NG?

Drilling rigs have methane detectors for obvious reasons.

They are only about $50 and I would highly recommend purchasing one for anyone whose water well might be affected by the Debroeck well. I'd bill it to Exco (as will my father-in-law).

PG,
I don't know exactly where in the pipeline the odor (do they still use methyl mercaptan?) is added to the gas, but I suspect it is somewhere after the wellhead. So if the casing is leaking, there will be no odor. Natural gas, i.e., methane, is odorless.
