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.
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).
Mud logging is usually performed by a third-party mud logging company. This provides well owners and producers with information about the lithology and fluid content of the borehole while drilling. Historically it is the earliest type of well log. Under some circumstances compressed air is employed as a circulating fluid, rather than mud.
A caliper log is a well logging tool that provides a continuous measurement of the size and shape of a borehole along its depth [1] and is commonly used in hydrocarbon exploration. The measurements that are recorded can be an important indicator of wash-outs, cave ins or shale swelling in the borehole, which can affect the results of other well ...

Spontaneous potential log, commonly called the self potential log or SP log, is a passive measurement taken by oil industry well loggers to characterise rock formation properties. The log works by measuring small electric potentials (measured in millivolts) between depths with in the borehole and a grounded electrode at the surface.
