Is this expected?Density Log. The density log usually labelled ‘RHOB’ measures the density of the borehole and the rocks penetrated by the drill bit. The unit for density is gram per cubic centimetre. The logs (sonic and density) measurements are usually made every 6 in. down hole, but must be aligned to be ‘on-depth’ with each other.The spectral gamma-ray log has found great success in the location of fractures in sedimentary reservoirs (e.g., Fertl et al., 1980). These are often (but not invariably) marked by anomalously high and localized levels of uranium, caused by the precipitation of uranium salts at fracture margins from migrating solutions.A scintillator ( / ˈsɪntɪleɪtər / SIN-til-ay-ter) is a material that exhibits scintillation, the property of luminescence, [1] when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate (i.e. re-emit the absorbed energy in the form of light).Gamma ray log signatures were utilized to infer depositional features, discriminate litho-units, and define depositional environment; resistivity log was employed to identify reservoir zones and formation fluids, while the combined density and neutron logs aided in the estimation of reservoir porosity and lithological typing.The Racheal Ray Show is popular for its fun host and tasty, approachable recipes.

The second data set used in this study incorporates gamma-ray logs and K2O analyses from the P-series of wells, in which the gamma-ray log was recorded in cps rather than API units.Gamma ray log. Early GR tools did not focus in one direction but gathered signals from all radial directions. For horizontal wells, this translates to incoming signals from both above, below, and sides of the wellbore. Ninety percent of the signal for the GR reading comes from within eight inches of the wellbore.A spectral gamma-ray (SGR) log was used to identify the type of clay minerals, depositional environment, and the relationship between total organic matter with uranium concentration. SGR log indicated that USS is composed mainly of chlorite, smectite, and illite clay minerals with the presence of kaolinite as a dominant clay mineral …The Gamma Ray log is a radioactive log that measures the natural radiation around the wellbore. Shales tend to give off a higher level of gamma radiation than other types of rock, which can be detected by this tool. The mineral composition of the shale can be determined by analyzing the energy spectra of the gamma ray population. The Induction curves are …Comprehensive study of seismic, well-logs and core data is essential in sequence stratigraphic analysis. In the absence of seismic and core data, gamma-ray logging is an important stratigraphic tool due to its sensitivity to shale content of strata. In this paper, gamma-ray log data are divided into two clusters. One cluster with higher average of gamma value is interpreted as being due to ...The gamma-ray log shows a conventional gray-shale response of about 130 API units in the Kinderhook Shale, but a huge increase in the Woodford Shale, with two zones exceeding 330 API units.

Is this expected?Gamma Ray Logs. Gamma rays are photons (particles of light) with energies ranging from 10 4 ev (electron volts) to 10 7 ev. Gamma ray logs are used to detect in situ radioactivity from naturally occurring radioactive materials such as potassium, thorium and uranium. In general, shale contains more radioactive materials than other rock types.Spectral gamma ray logging is based on the principle that different radioactive elements emit gamma rays with different energy levels. By using a …The log data obtained at sea have been corrected for borehole size changes, the effects of drilling fluids, and logging-speed variations. The processed logs are then used to calculate the amounts of the three major radioactive elements (Th, U, and K) and the dry weight percentages of oxides every 0.1524 m throughout the logged intervals.1. n. [Formation Evaluation] The unit of radioactivity used for natural gamma ray logs. This unit is based on an artificially radioactive concrete block at the University of Houston, Texas, USA, that is defined to have a radioactivity of 200 American Petroleum Institute units.This was chosen because it was considered to be twice the radioactivity of a typical shale.The ….
