How about injecting some fact in the Oil and Gas reality of NB.. For example wells that are already producing and the substantial potential for further development. Copy of Letter to the Editor by Janet Matheson in the Telegraph Journal back home in NB... ___ ___ ___ ___ ___ ___ ___ ___ ___ No need for elbow, sharp degree fracks To the letter writer (“Minister should debate opponents,” April 8) and others, here is some “verifiable reality“ about New Brunswick and natural gas. There have been four shale natural gas wells vertically drilled and then fracked conventionally on a incline in New Brunswick. Only one, F-58, is producing. There are no radical elbow or sharp 90 degree fracks in New Brunswick – there’s no need. The formation here is in three layers. The first layer is the Hiram Brook Sands -- this is sandstone and it is 40 to 850 metres thick. The producing wells in New Brunswick are in the Hiram Brook sandstone – all except one. Those wells are on average 2,400 meters below the surface and fracked at a slight deviation just because the formation is so thick. Next is the Frederick Brook Shale. The F-58 well was drilled to a depth of over 3,120 metres and it has been producing since 2008. This part of the formation is assessed at 67 trillion standard cubic feet and is from 900 to 1,164 metres thick, the thickest shale formation known to geologists. The pictures of radical elbow fracks are not New Brunswick’s experience. Those elbow fracks are necessary in the United States because the shale formation is skinny but covers a large area. That is the reason they need that sharp right angle and the long horizontal frack -- that is the resource rock area. The U.S. Marcellus Shale is just 90 meters at its thickest! First, we have the sandstone; then, the shale and below those two rock formations, is the Dawson Settlement member. It is dominantly 600 meters of laminated marlstone and that is oil -- 270 million barrels -- in situ reserves. Jim Emberger’s work is in the U.S., but it’s time to“know” New Brunswick.
