Gas Lift Systems in the Alger Oil Field -- The Bakken, North Dakota, USA

Elsewhere they are talking about gas lift systems for Bakken oil wells. They mention two such wells:
  • 19198, Arvid Anderson
  • 18896, Clifford Bakke
It's purely coincidental that I just posted results of the Clifford Bakke well as part of my update on BEXP permits for a 5-well pad in the Alger oil field.
  • 18896: 4,438, BEXP, Clifford Bakke 26-35 1-H, s6/10; t10/10; cum 243K 9/11; remember: it often took the Madison to produce for 20 years to get to 100,000 bbls
I don't know if the gas lift system had any different effect on the Clifford Bakke compared to what a conventional pump would have done. The Alger field is a huge success, in no small due to BEXP's effectiveness, and it certainly appears the IPs have more correlation than subsequent types of pumps, but time will tell.

Now, up to this point, I have not looked at the Arvid Anderson well, so let me go find it, and place information here (this is just like opening a Christmas present, not knowing what I will find, but probably pleasantly surprised):
  • 19198, 2,834, BEXP, Arvid Anderson 14-11 1H, s 8/10; t11/10; cum 136K 9/11
So the well has produced 136,000 bbls of oil and its not yet a year old (since test date).

Yup, pleasantly surprised -- well, actually not surprised. The BEXP wells in the Alger have, for the most part, reported huge IPs. And so, another BEXP well that has paid for itself at the wellhead, and will now continue to produce for the next 25 years.
