The Horn River Basin, very little was known about the play until Feb 28, 2008, when Houston-based EOG Resources Inc. said it might have reserves of six trillion cubic feet – the same as Mackenzie Delta, Northwest Territories, and a figure that would increase Canada’s total proved reserves by roughly 10 per cent.
EnCana Corp. of Calgary – which claims the initial discovery of Horn River’s potential – and partner Apache Corp. of Houston may also have 6 trillion cubic feet of gas, Apache said in early February.
British Columbia is set for a frantic land grab by natural gas explorers, following months of speculation and intensified by last week’s announcement of what could rank among the largest gas discoveries in Canadian history. Land sales are conducted twice a month in Alberta, once a month in British Columbia, and every two months in Saskatchewan. Wells at Horn River are expensive, roughly $10-million per hole. Horn River – as well as the hot Montney play further south in the same area of B.C. – faces challenges beyond geology, led by its remoteness, where drilling is conducted in winter because rigs can only make it to locations when the rugged ground is frozen.
Estimates for gas content in the sandstones, siltstones and shale sequences of the Triassic-aged Montney formation in northeastern British Columbia put the resource size at about 50 trillion cubic feet (tcf) over an area of about 680 square miles (73 billion cubic feet per section). This estimate is near the bottom end of the range of the B.C. government estimates of 30 tcf for the Upper Montney and 50 tcf in the Lower Montney in B.C. alone. the report says. The current focus is the Upper Montney which is being developed by drilling horizontal wells with multi-stage fracs. The economics have improved from a break-even prospect using vertical wells to a 27% expected internal rate of return (IRR) using horizontal wells. The limited facilities and pipelines in the areas will constrain significant production growth until new infrastructure is added. Raymond James says wells in the Barnett Shale play in Texas show similar characteristics to the Montney (for example, first-year average production), but the Barnett wells have higher internal rates of return — primarily due to faster completion times — and hence lower wells costs. In the Montney, average horizontal well costs have fallen to the $4-$5.5-million range (drilled and completed) — much better than 18 months ago when some horizontal wells were still costing $7-$8 million, the report says.
Montney players (either on the producer or service side) include Murphy Oil Corporation, Ensign Energy Services Inc., Storm Exploration Inc. and Sabretooth Energy Ltd., EnCana Corp, Duvernay Oil Corp. and Birchcliff Energy Ltd, ARC Energy Trust among others.

Saudi Arabia announced on Thursday that they will start adding 500,000 bpd to its total capacity when the Khursaniyah field comes on stream this month. Abdulaziz al-Judaimi, vice president of new business development at Saudi Aramco said, “The Khursaniyah field will start producing within a month at 300,000 bpd and will eventually add 500,000 bpd to the country’s production capacity.”
The United states has the Thunder Horse deep sea oil project in the Gulf of Mexico, which should produce 1 billion barrels of oil with 250,000 barrels per day. The Bakken needs pipelines and refinery capacity to reach its full potential, which I think is (US and Canada combined) 250,000 bopd by 2008 and 500,000 bopd by 2010 and 1 million bopd by 2013 and 2 million by 2015. Bakken could go higher but then it would require new drilling technology advances for higher recovery. I think that will happen as well.
The US part of the Gulf of Mexico could be producing a daily yield of 800,000 and accounting for 11 percent of US oil production by 2011. This would be follow up to the Jack2 test well by Chevron, which indicates 3-15 billion barrels of oil.
