The gamma ray log is useful in holes drilled with air or with oil based muds, as these wells have no SP voltage. Even in water-based muds, the gamma ray and SP logs are often run together. They comprise a check on each other and can indicate unusual shale sections which may either not be radioactive, or may have an abnormal ionic chemistry.
Gamma-ray measurement has the following applications: Well to well correlation: gamma-ray log fluctuates with changes in formation mineralogy. As such, gamma-ray logs from different wells within the same field or region can be very useful for correlation purposes, because similar formations show similar features.
A common gamma-ray log records the total radiation and cannot distinguish between the radioactive elements, while a spectral gamma ray log (see below) can. For standard gamma-ray logs, the measured value of gamma-ray radiation is calculated from concentration of uranium in ppm, thorium in ppm, and potassium in weight percent: e.g., GR API = 8 ...
The Spiller Farm Paleoindian Site, designated Site 4.13 by the Maine Archaeological Survey, is a prehistoric archaeological site in Wells, Maine.Located overlooking a stream on the Spiller Farm property on Branch Road, it is an extensive site at which a fine collection of stone artifacts has been found, dating to c. 8,000 BCE.
In 2004 H.E.S.S. was the first IACT experiment to spatially resolve a source of cosmic gamma rays. In 2005, it was announced that H.E.S.S. had detected eight new high-energy gamma ray sources, doubling the known number of such sources. As of 2014, more than 90 sources of teraelectronvolt gamma rays were discovered by H.E.S.S. [2]
Moody Beach is a coastal neighborhood and private beach located in Wells, Maine, with about 100 homes adjoining the beach. Moody Beach has a blend of year-round and summer residents, as well as short-term vacationers from around New England and Quebec .
Glenburn is a town in Penobscot County, Maine, United States.The population was 4,648 at the 2020 census. [2] When originally incorporated in 1822, it was called "Dutton" in honor of Bangor's Samuel Dutton, a judge and founder of the Bangor Theological Seminary.
