“…This facility consists of a microfocusing X-ray tube (Hamamatsu L9191) with exchangeable targets (Ti, Mo, W, and Ag targets are available), a highresolution X-ray sensitive CCD camera (Photonics Science VHR-70), and a precise specimen positioning system. The facility allows the imaging of microstructures with a maximum spatial resolution of 4 μm [24]. During each measurement, 1800 projections were collected, using the high-performance X-ray CCD camera (Photonic Science VHR 70 mm).…”

The main goal of the research was to employ the unique data delivered by various methods to improve the determination of rock reservoir properties. Results of Xray computed tomography (XRCMT), one of the newest techniques providing high-resolution images of rocks, were used to show that very precise information from this tool is complementary to results from other methods. Standard laboratory measurements (helium pycnometer, mercury injection porosimetry, permeameter) and sophisticated experiments (X-ray computed tomography and nuclear magnetic resonance spectroscopy) were performed to obtain and compare results. Four types of specimens: typical Miocene sandstone-mudstone-claystone rock samples, artificial corundum specimens, shale gas plugs, and limestone sample were investigated to obtain the porosity, permeability, density, and other parameters used in rock descriptions. Mutual relationships between selected groups of rock material properties were presented to provide an integral picture of rock characteristics. The XRCMT results were in general not influenced by lithology, but there were observed Oil and Gas Institute -National Research Institute, Krakow, Poland shaliness effects on the shape of pores, cross sections, and the tortuosity of porous channels. An analysis of the average porosity and the standard deviation of each XRCMT plot provided information about differences in the heterogeneity of a formation. Thus, the XRCMT method was recommended in pore space parameter determination for microfracture fluid propagation monitoring. There was also observed equivalence between part of the NMR signal from clay-bound water and the XRCMT volume subgroups in porosity/permeability-structural classes I and II. So, the use of the two-subsample approach in the XRCMT interpretation was promoted.

“…The basic characteristics of the system and its construction details were given in the report. Another article by the same research group with Bielecki as principle author 25 gave more details of the spectrometer with preliminary results of m-CT measurements. Yang et al 26 built a new glancing incidence X-ray fluorescence (GIXRF) spectrometer by collimating the incident beam using a parallel polycapillary lens.…”

Prop er ties of se lected Pre cam brian and Pa leo zoic sed i men tary clastic rocks were analysed with re spect to their res er voir po ten tial. Mul ti di men sional anal y sis of lab o ra tory re sults and bore hole log ging data was used to con struct dig i tal mod els of pre-Me so zoic, deeply bur ied for ma tions, pres ent as tight, low-po ros ity and low-per me abil ity rocks. This mod ern sta tis ti cal and de ter min is tic ap proach as ap plied to lab o ra tory and bore hole log ging re sults worked to in te grate data at dif fer ent scales. The re sults ob tained are use ful not only in fur ther sci en tific re search but also found a use in in dus trial ap pli ca tion.

Next, the mod els con structed were ap plied in bore hole log ging in terpre ta tion to find in ter vals with sim i lar petrophysical prop er ties within the group and dif fer ent prop er ties be tween the groups. This ap proach al lowed im ple men ta tion of upscaling pro ce dures of lab o ra tory ex per i ments at mi cro-and nano-scale to borehole log ging scale.
