Production at Elm Coulee has more than doubled the oil output of the state of Montana, from around 40,000 barrels per day (6,400 m 3 /d) in 2000 to almost 100,000 barrels per day (16,000 m 3 /d) in 2006. However, Montana production fell again starting in 2007, down to some 70,000 barrels per day (11,000 m 3 /d) in mid-2009. [9] [10]
There are at least 45 named oil fields in Montana according to the U.S. Geological Survey, Board of Geographic Names. The USGS defines oil field as: "Area where petroleum is or was removed from the Earth." [1] An oil field is a region with an abundance of oil wells extracting petroleum (crude oil) from below ground.
Cat Creek Oil Field (1921) The Cat Creek Oil Field is located near the community of Cat Creek in Petroleum and Garfield counties in the U.S. state of Montana.The geological terminology used by Bowen, the geologist, to define the geological structure of Cat Creek in 1914 was Cat Creek Anticline.
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole.The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs).
A drilling rig is used to create a borehole or well (also called a wellbore) in the earth's sub-surface, for example in order to extract natural resources such as gas or oil. During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of ...
[1] [2] These documents include maps, field notes and well logs relevant to geothermal exploration and development. Some of the information was originally gathered for use by the oil industry. [ 3 ] NGDS facilitates the digitization of this data, and ensures that data from various sources is stored in a compatible format to facilitate ...

Of all the well data sets recorded and collected, well logs are the most valuable as they are vital for reservoir and formation evaluation. Wireline (well) logs are then combined with drilling data, mud logs , and measurements while drilling (MWD) and coring information in order to choose correct testing and completion intervals to properly ...
