[5] DNRC has six divisions: [6] The Director's Office—This division provides policy and managerial leadership for the department, and administrative support services to itself and other divisions, boards, and commissions.
A controlled ground water area (CGWA) is a category defined by the Department of Natural Resources and Conservation (DNRC) of the state of Montana.A CGWA must satisfy a set of criteria, including ground water withdrawals in excess of recharge; excessive declines in ground water levels or pressures; possibility of contaminant migration; or the existence of significant disputes within the area ...
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 ...
Log ASCII standard (LAS) is a standard file format common in the oil-and-gas and water well industries to store well log information. Well logging is used to investigate and characterize the subsurface stratigraphy in a well. A single LAS file can only contain data for one well, but it can contain any number datasets (called "curves") from that ...
The Montana Department of Environmental Quality is a state-level government agency in Montana. The agency was founded by the Montana Legislature in 1995 as the Montana Board of Environmental Review. [1] It is responsible for monitoring air, water, energy, and mining standards, in addition to regulatory services. [2] [3] [4]
Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).. Although the terms Measurement while drilling (MWD) and LWD are related, within the context of this section, the term MWD refers to directional-drilling measurements, e.g., for decision support for the smooth operation of the drilling, while ...
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).
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 ...
