Abstract: A method for determining a property of earth formations surrounding a borehole, including the following steps: isolating a region of the borehole, and obtaining a sample of borehole fluid from the isolated region; and implementing measurements, dowhole, of the Raman scattering of electromagnetic energy directed at the fluid sample; the property of the earth formations being determinable from the measurements. In a disclosed embodiment, the steps of isolating a region of the borehole and obtaining a sample of borehole fluid from the isolated region include: providing a logging device in the borehole in sealing engagement with the isolated region, causing formation fluid from the isolated region to flow in a flow line of the logging device, and providing a measurement cell in the logging device which receives the sample of formation fluid via the flow line.

Abstract: Systems, methods, and devices for inelastic gamma-ray logging are provided. In one embodiment, such a method includes emitting neutrons into a subterranean formation from a downhole tool to produce inelastic gamma-rays, detecting a portion of the inelastic gamma-rays that scatter back to the downhole tool to obtain an inelastic gamma-ray signal, and determining a property of the subterranean formation based at least in part on the inelastic gamma-ray signal. The inelastic gamma-ray signal may be substantially free of epithermal and thermal neutron capture background.

Abstract: A neutron generator includes a sealed envelope providing a low pressure environment for a gas. One end of the envelope defines an ion source chamber. A target electrode is disposed at the other end of the envelope. An extracting electrode is spaced apart from the target electrode by an accelerating gap. The extracting electrode bounds the ion source chamber. A dispenser cathode electrode and grid electrode are disposed in the ion source chamber for inducing ionization in the ion source chamber. The dispenser cathode electrode, the grid electrode and the extracting electrode operate at a positive high voltage potential and the target electrode operates at or near ground potential. This configuration provides an electric field gradient that accelerates ions towards the target electrode to induce collisions of ions with target material, thereby causing fusion reactions that generate neutrons. High voltage power supply circuit means supplies a positive high voltage signal to the electrodes of the ion source. The positive high voltage signal has a low voltage signal component floating on a positive high voltage signal component. For the dispensing cathode electrode, the low voltage signal component can be a DC or AC signal suitable for emitting electrons from the dispensing cathode electrode. For the grid electrode, the low voltage signal component can be a positive pulsed-mode signal (preferably with magnitude in the range between 100 to 300 volts). High voltage insulation surrounds and electrically insulates the high voltage power supply circuit means. Other ion source electrode configurations, such as cold cathode (Penning) ion source and RF-driven ion source, can also be used.

Abstract: Measurement of gas flow in a nearly-horizontal ascending borehole utilising a pair of correlated spaced sensors (49n, 49f) that can detect "directly" the difference between gas (11) and liquid (13: oil and/or water), which sensor pair (49) is carried on a logging tool (41) positioned within the borehole (20) itself such that the individual sensors (49) are disposed so as to be actually in the path of any gas bubbles (12) likely to be in the fluid. The correlated output of the sensor pair (49) allows a determination of the gas flow velocity, and if at the same time measurements are taken that provide an indication of the hold-up of the gas bubbles there may by calculation be determined the flow rate both of the gas and of the fluid.
