A method for real time on-stream analysis of oil sands composition is disclosed comprising the steps of detecting a moisture content of an oil sands stream using a microwave transmission analyzer, detecting an elemental composition of the oil sands stream using a prompt gamma neutron activation analyzer and calculating a content of hydrocarbons, clays and sands in the oil sands stream. The total clay amount in the oil sands stream is based on the detected gamma spectra of several elemental components of the oil sands stream, such as sodium, magnesium, potassium, calcium and iron.

A measuring system includes a detector having an optical waveguide including a primary dopant capable of transmuting, by neutron capture, into a stable secondary dopant that is less neutron-absorbent than the primary dopant, a moderation layer suitable for slowing down fast neutrons, and an analysis device connected to the detector. The analysis device is configured to inject, into the waveguide, an interrogation wave having a wavelength corresponding to an absorption peak of the secondary dopant, detect a response wave emitted by the waveguide, calculate, from the detected response wave, a piece of information relating to a concentration of secondary dopant in the waveguide, and, based on the information relating to the calculated concentration of secondary dopant, determine a fluence of fast neutrons during a predetermined secondary period.

This disclosure presents systems and processes to collect elemental composition of target fluid and solid material located downhole of a borehole. Waveguides can be utilized that include capillary optics to deliver emitted high energy into a container or a conduit and then to detect the high energy. A source waveguide can be used to emit the high energy into the target fluid and a detector waveguide can collect resulting measurements. Each waveguide can include a protective sheath and a pressure cap on the end of the capillary optics that are proximate the target fluid, to protect against abrasion and target fluid pressure. In other aspects, a pulsed neutron tool can be utilized in place of the waveguides to collect measurements. The collected measurements can be utilized to generate chemical signature results that can be utilized to determine the elemental composition of the target fluid or of the solid material.

A concentration detector includes: a neutron source emitting neutrons to a target; a gamma ray detector detecting and determining an amount of specific gamma rays that are among gamma rays generated in the target by interactions with the neutrons; and a concentration calculator calculating a concentration of the target at selected depths in the inspection target, based on the detected amount. A relational expression expressing a relation between a plurality of concentrations of the target in a plurality of virtual layers and a detected amount of the specific gamma rays is predetermined for each type of the specific gamma rays or each detection condition. The concentration calculator applies the detected amount for each gamma ray type or each detection condition, to the relational expression for the type or the detection condition, and calculates a concentration of the target component in the layer at each depth or the specific depth.
