Abstract: A wireline-conveyed side-wall core coring tool for acquiring side-wall core from a geological formation for performing in-situ side-wall core analysis. The coring tool has a core analysis unit operable to measure geophysical properties of an acquired side-wall core. The measured geophysical properties may be used to determine the success of the acquisition of side-wall cores by the coring tool. The core analysis unit is operable of performing an in-situ interpretation of measured geophysical property of the side-wall core and transmitting in near real-time the measurements or the interpretation results to surface data acquisition and processing apparatus.

Abstract: A betatron structure having a donut-shaped vacuum chamber, wherein the vacuum chamber is made up of two or more pieces bonded together; an injector positioned within the vacuum chamber; and two or more magnets positioned to the outside of the vacuum chamber. A method of manufacturing a betatron structure, including: (a) fabricating two or more pieces; (b) positioning an injector on one of the two or more pieces; and (c) bonding the two or more pieces such that when bonded, the substrates form a hollow donut-shaped chamber.

Abstract: An oil sample is subjected to nuclear electromagnetic irradiation downhole, and the electron and/or mass density of the oil sample is determined by measuring the attenuation of the irradiation and relating the attenuation to the electron density. If the irradiation is high energy gamma ray irradiation, the attenuation is considered to be a function of Compton scattering only, which in turn is related to the electron density of the sample. If X-rays are utilized, attenuation is preferably measured in two energy windows. Using the two different attenuation values found in the different windows, the attenuation due to Compton scattering can be found and related to the electron and/or mass density of the sample. In addition, attenuation due to photoelectric absorption may also be determined and related to the presence of one or more heavy elements in the oil (e.g., sulfur) and/or sanding.
