There are described herein methods and system for generating an inspection image of an object from radiographic imaging. The method comprises obtaining a plurality of digital images of the object positioned between a radiation source and a photon beam detector, the digital images taken at different object-detector distances or source-detector distances to create unique grain diffraction patterns in each one of the digital images, and forming the inspection image from image features common to the digital images at a common scale and removing the unique grain diffraction patterns.

A method of inspecting a separation vessel may utilize off axis gamma scanning. During scanning, a gamma radiation source can emit gamma radiation through a separation vessel toward a detector, and the detector can detect radiation emitted by the gamma radiation source and passing through the separation vessel. The gamma radiation source may be positioned at a first vertical elevation along the separation vessel and the detector positioned at a second vertical elevation along the separation vessel different than the first vertical elevation. As a result, a radiation path may be defined between the gamma radiation source and the detector that transects the separation vessel at a non-zero degree angle with respect to a horizontal plane.

An apparatus for in-line mud logging is adapted to be in material communication with a conveyor used for conveying drilling fluid and/or drill cuttings from a well. An analysis body, disposed in the path of material falling from the conveyor has a sample accumulation tray for collecting a sample of material falling from the conveyor, and a gamma-ray detector for acquiring gamma-ray spectra from the sample of material. A weight sensor detects weight of the sample of material. A sample removal device is used to remove the sample of material from the sample accumulation tray after a desired sample interval. Signals from the gamma-ray detector and the weight sensor are communicated to a control unit.

A system for real-time or near real-time analysis of drilling fluid, drill cuttings and/or mud gas transported from a well to a mud circulation system has a hydrocarbon analysis device for in-line measuring hydrocarbon content in the material and an in-line gamma-ray detection apparatus. The in-line gamma-ray detection apparatus is disposed in the path of material transported from the well. A control unit for real-time or near real-time receives and correlates signals from the hydrocarbon analysis device and the in-line gamma-ray detection apparatus.

There is described a method for forming an inspection image of an object from radiographic imaging. The method has: forming the inspection image including scaling a feature of the object in one or more digital images to a common scale, the digital images including first and second digital images of the object, the first digital image having the feature at a first scale, the first digital image having a first grain diffraction pattern at the first scale, the second digital image having the feature at a second scale different from the first scale, the second digital image having a second grain diffraction pattern at the second scale, the second grain diffraction pattern different from the first grain diffraction pattern, the common scale common to both the first and second digital images after said scaling, and removing grain differences between the first and second grain diffraction patterns at the common scale.
