World proved reserves (billion barrels)
- Ghawar, Saudi Arabia: 140
- Rumalia, Iraq: 22
- Cantarell, Mexico: 11 - 20
- Prudhoe Bay, Alaska: 13
- Tupi, Brazil: 5 - 8
- Bakken: 11 - 24 (depending on analyst)
- Total official estimated US reserves: 19 billion
- 24 - 30 stage fracs
- 8 stages per day
- Sand + ceramic proppant
Increasing production rates (90-day average) (my estimate based on graph)
- 2007: 180 bbls/day
- 2008: 220 bbls/day
- 2009: 400 bbls/day
- 2010: 450 bbls/day
More frac stages = higher EURs
CLR using 518 as representative for EUR in presentation
Similar to Whiting, CLR is estimating 8 horizontals on 1280-acre spacing units
CLR says IHS esimates North Dakota to produce 1,000,000 bbls opd by 2020; I've seen others suggest 1 million by 2015. The delta probably relates to infrastructure and takeaway capacity.
Bruce, do you have any idea what Hess is doing in T156-R94 Sections 2&11? A series of wells, spaced around a lateral, with the name "PERSON OBSERVATION"???
ReplyDeleteThanks,

You beat me to the punch. I remember seeing these earlier and forgot to check up on them.
ReplyDeleteBut, no, I have no idea what Hess is doing, but one can imagine.
Big Butte oil field is northwest of their cash cow (the Sanish), and is midway between the old Tioga fields and the Cottonwood, a so-so (average) field.
With all the recent talk about stacked laterals and offset wells; about four Bakken wells and four TF wells in 1280-acre units; and, suggestion that Bakken and TF do not communicate, my hunch is that Hess is looking to see if this will all play out in this area: multiple horizontals in same area, targeting different formations, and determining if they affect each other. If the formations do not communicate, Hess' proved reserves in this area goes up significantly.
But, nothing official; simply conjecture.
You probably saw this, and that's probably what raised the question: Hess was issued another permit along that same lateral. This fifth well (permit #20539) raises the number of wells along this horizontal to five wells. None of these have the "H" designation, suggesting they are simply vertical (monitoring wells).
