I was looking at the completion reports for our two wells and noticed that there is a “choke size” mentioned. Checking on other completed Noble wells, I saw that the choke size varied. Ours was 32 but wells with higher initial production had higher numbered choke sizes. Wells with lower initial production had lower numbered choke sizes. In an effort to understand what that meant, I went searching.
I came across a post on a site called PeakOil.com by someone who is respected on that site and seems to be an industry insider. He wrote about choke sizes and initial production. He pointed out that different choke sizes would produce different initial production numbers, and so those numbers were not necessarily of great importance. In addition, wells with high initial production numbers could sometimes peter out pretty quickly while wells with lower numbers have sometimes been known to produce more in the long run.
So then I began to wonder why oil companies are required to post initial production numbers if the numbers don’t necessarily reflect the well’s potential production. And I also wondered if oil companies play games with those numbers in an effort to mislead other companies about the well’s potential production.
