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.

Detecting downhole fluid composition utilizing photon emission

The disclosed embodiments include methods to perform an in-situ determination of a formation property of a downhole formation, methods to operate a tool to perform an in-situ determination of formation properties of a downhole formation, and in-situ formation property measurement tools. In one embodiment, a method to perform an in-situ determination of a formation property includes deploying a tool into a borehole that is drilled through a formation. The method also includes isolating a source zone from an injection zone. While the source zone is isolated from the injection zone, the method further includes withdrawing a fluid that partially fills the source zone; flowing the fluid into the injection zone; injecting the fluid into a first portion of the formation that is along the injection zone; and determining at least one formation property of the first portion based on an injection of the fluid into the first portion.
