2836: Almost 2 Million Barrels of Oil Since 1961 -- Still Producing; A Madison Well

Elsewhere, "AmericanOilND" asked for past six months production for well #2836. This is the production. See below table for background.

This is another good example of why oil companies are excited about the Bakken, and why I remain inappropriately exuberant about the oil industry in western North Dakota.

For newbies, how to read the above:

The pool: a Madison well. The Madison is one of the legacy formations in North Dakota. It is one of the formations that has been reliably producing since oil was discovered in 1961.

Spud date: they started drilling 2/6/1961 

Oil field: the Williston Basin is made up of hundreds of administratively apportioned oil fields; the Clear Creek field is one of them.

Note the cumulative water: 1.4 million bbls. There is generally not a lot of water associated with a Madison well, so this suggests that they are using water injection: pushing large amounts of water into the well to force the oil out; the water will come back up with the oil and have to be trucked away for disposal.

Natural gas: this well has also produced about 1.8 million thousand cubic feet of gas.  The "M" in "MCF" stands for "thousand). A "thousand million" is a billion, so in this case it has produced about 1.8 billion cubic feet of gas. The conversion rate for "barrels of oil equivalent" for natural gas is about 6,000. Dividing 1.8 billion by 6,000, one gets: 300,000 barrels of oil equivalent, a not inconsequential amount if natural gas brought a decent price, which it doesn't.

Status: "AL" means "artificial lift" -- a pump.

Two million bbls of oil and this well is still pumping. It has met the criteria for a stripper well, and if granted that status, is granted a significant tax break. State taxes are essentially cut in half when a well is deemed a "stripper" well. 

And on top of all this, Clear Creek is a great Bakken field, also.

  1. Where exactly is the Clear Creek field located? This is an amazing showing for an old vertical well. Makes me wonder about some of the many P&A'd wells in the Williston Basin area.

  2. It's a very small field, right in the middle of the Bakken. It's south and west of the river, west of the reservation. It is very near some other good fields, including the Charlson.

    I can't give you any towns, because there are none to speak of. It's about 15 miles northeast of Watford City, North Dakota.
