…situation under control – CDC
The well at Sixth Street, Diamond, East Bank of Demerara, which erupted again on Wednesday spewing debris up to 50ft in the air, consisting of mud, water, gas and small boulders on nearby houses is currently under control and is continuously being monitored.
Director General (ag) of the Civil Defence Commission (CDC), Lt. Col. Kester Craig said the eruption of the well occurred around 01:30h and immediately following the 24-hour National Emergency Operation Centre was contacted and a team dispatched to the location.
Officials from the CDC, Guyana Geology and Mines Commission (GGMC), the Guyana Police Force (GPF) and the Guyana Fire Service (GFS) were on the ground monitoring the situation.
Lt. Col. Craig explained that about two weeks ago engineers from the GGMC completed the initial capping.
This process entails what is known as “reverse welling” and involves the use of two sets of pipes, which are placed about 25 feet below the ground to trap the gas at the surface, “it involves using cement to seal around the pipes and the affected areas,” Craig noted.
The process takes 21 days to “cure.”
From the assessment conducted yesterday by Senior Petroleum Technologist, GGMC Mitchell Prince, it was determined that an apparatus would have to be set up to capture the combination of gas, mud and water and then separate the gas from the mixture.
Prince, who performed the initial capping of the well, said this occurrence is normal and indicates that the well is clear. However, according to the Craig “we have to be careful with the size of the boulders coming out because the surface at the top has to be adequate for the release of the boulder from the well.”
An assessment was also conducted by the Environmental Protection Agency (EPA) and Massy, which ruled out the presence of excess amounts of methane gas in the atmosphere.
A sample of the methane gas was sent overseas to determine the quantity and potential, which initial tests reveal is in significant amounts.
Lt. Col. Craig said several recommendations were received including the placement of a gas generator to provide electricity to the community or having a private investor collect the gas for commercial distribution.
According to a DPI release, following a complete assessment, a report will be submitted to Minister of State, Joseph Harmon for an executive decision to be made in this regard.
Craig is also urging citizens to refrain from drilling wells without permission from the Hydromet Office to avoid a similar situation, which has resulted in significant losses.
He disclosed that authorities are currently reviewing the laws to ascertain possible sanctions for the homeowner responsible for the eruption in June after he claimed to have been digging a domestic water well.
Nearby residents were assured that the situation is under control and a solution forthcoming following assessment.
