As for the pulsed neutron spectroscopy log, absolute concentrations can be derived by calibration to core or by using a model such as the oxide-closure model. The absolute elemental concentrations can then be converted into mineral concentrations using a model that defines what minerals are present.
The first complete geochemical logs were run in the mid s. The oxide-closure model for converting relative elemental yields from a pulsed neutron spectroscopy log to absolute weight concentrations uses the assumption that the sum of all oxides in the rock matrix is 1. The weight percent of an oxide can be calculated from the dry weight percent of the cation by knowing the chemical formula.
Since the sum of all Wi equals 1. Unlike earlier versions it does not use a pulsed neutron source but uses instead a standard americium beryllium AmBe neutron source and a large bismuth germanate BGO detector to measure relative elemental yields based on neutron-induced capture gamma ray spectroscopy. The primary elements measured in both open and cased holes are for the formation elements silicon Si , iron Fe , calcium Ca , sulfur S , titanium Ti , gadolinium Gd , chlorine Cl , barium Ba , and hydrogen H.
Wellsite processing uses the channel gamma ray energy spectrum to produce dry-weight elements, lithology, and matrix properties. The first step involves spectral deconvolution of the composite gamma ray energy spectrum by using a set of elemental standards to produce relative elemental yields.
The relative yields are then converted to dry-weight elemental concentration logs for the elements Si, Fe, Ca, S, Ti, and Gd using the oxides closure method. Matrix properties and quantitative dry-weight lithologies are then calculated from the dry-weight elemental fractions using empirical relationships derived from an extensive core chemistry and mineralogy database. Log analysis is done at the wellsite by the operating program so it may be difficult to do an independent analysis from the raw log curves..
The Pulsar log is essentially a combination of an ECS and RST with a few extra features - great for monitoring older wells for workover or locating bypassed pay. Raman spectroscopy Raman Spectroscopy is an analytical technique in which the scattered light is used for measuring the vibrational energy modes of a sample. Raman Spectroscopy The non-destructive chemical analysis technique of Raman Spectroscopy offers in-depth information about the chemical phase, structure and polymorphy, molecular interactions, and crystallinity.
