A method for compensating the settings of a pulsed X-ray system. The method selects current, voltage, and intended pulse width settings for the X-ray pulses. The method then compensates the selected pulse width setting for the set voltage and tube current, in accordance with at least one stored normalized value at a predetermined temperature, taking into account the environmental temperature of the electric circuitry of an X-ray tank of the X-ray system. The at least one normalized value is obtained in a calibration step based on the actual pulse width and the difference thereof with the intended pulse width at a predetermined temperature, taking into account the internal temperature of the X-ray tank.

An x-ray-based reservoir evaluation tool for measurement variations in formation density anticipated at the water-oil interface of a reservoir is provided, the tool including at least: an internal length comprising a sonde section, wherein said sonde section further comprises an x-ray source; radiation measuring detectors; sonde-dependent electronics; and a plurality of tool logic electronics and PSUs. A method of using an x-ray based reservoir evaluation tool for measuring variations in formation density anticipated at the water-oil interface of a reservoir is also provided, the method including at least the following steps: using x-rays to illuminate the formation surrounding the cased borehole; uses detectors to directly measure the density of the formation; using detectors to directly measure the effects on the measurement from tool stand-off or production liner attenuation; and employing techniques for compensating for the production liner and liner-annular region when computing the saturated formation density within the production interval.

A protective case for a handheld x-ray emitter device, and a handheld x-ray emitter device protected by the protective case. Conventional handheld x-ray emitter devices include a tube barrel and a trigger handle connected to the tube barrel. The junction where the trigger handle connects to the tube barrel can be a point of structural weakness in the handheld x-ray emitter device. The protective case covers portions of the handheld x-ray emitter device so as to structurally reinforce the junction between the tube barrel and trigger handle, while still allowing the handheld x-ray emitter device to be operated.
