Abbreviations & parameters

With a few exceptions, the Montana weekly oil activity report includes horizontal well activity in the Bakken petroleum system in the eastern/northeastern part of the state within the Williston Basin. It also includes the Heath play and what is referred to as the South Alberta Bakken fairway in northwestern/west-central Montana, which is at least 175 miles long (north-south) and 50 miles wide (east-west), extending from southern Alberta, where the formation is generally referred to as the Exshaw, southwards through Montana’s Glacier, Toole, Pondera, Teton and Lewis & Clark counties. The Southern Alberta Bakken, under evaluation by several oil companies, is not part of the Williston Basin.

Following are the abbreviations used in the report and what they mean.

BHL: bottomhole location | BOPD: barrels of oil per day | BWPD: barrels of water per day

IP: initial production | MCFPD: thousand cubic feet per day | PBHL: probable bottomhole location

PD: proposed depth | SHL: surface hole location | TD: total depth

And public land survey system abbreviations:

FNL = from north line | FEL = from east line | FSL = from south line | FWL = from west line
