Encana Corp. gave Texas regulators final figures from an oil rig accident east of Karnes City where the company said 138,000 gallons of crude oil worth more than $197,000 spewed into the air and onto the surrounding countryside.
The Calgary, Canada-based company submitted its final report to the Texas Commission on Environmental Quality (TCEQ) last week.
A copy of the report provides new details into the May 19 accident at the Dromgoole B 8H oil well off FM 792 in rural Karnes County.
Encana reported the oil rig accident released tens of thousands of pounds of 18 different types of gases as well as 760,956 pounds of crude oil into the air.
Based on the specific gravity of the crude oil, the amount released into the air is equal to approximately 3,293 barrels of oil, which at the current market price of $60 a barrel would have been worth $197,580.
The company has not faced regulatory action yet, but the accident remains under investigation by the Texas Railroad Commission, which is the state agency that regulates the oil-and-gas industry, and the TCEQ.
In the company’s final report, Encana officials told the TCEQ they calibrated and tested the equipment while the surface pressure was set at 0 psi.
Encana reported that crews with AAA Well Service had 67 joints of tubing with five gas lift mandrels tripped in hole. While connecting another joint at the surface, a “downhole failure” happened causing a loss of pressure control that sent gas and crude oil into the sky.
The company contracted Boots & Coots well control specialists, who brought the rig under control in just under 24 hours but Encana estimated more than 1,000 acres of land ended up affected.
Since the accident, Encana employed subcontractors to control runoff, pump out nearby stock tanks, evaluate livestock, take soil samples, evaluate vegetation, clean homes and repair nearly half a mile of roadway on FM 792.
Out of nearly two dozens homes evacuated during the accident, Encana said three families remain at a local hotel where the company is paying for lodging and meals while the remediation efforts continue.
