... of dissolution CO2 and glauconite in the sands. The first example is a sandstone formation that contains a sequence of sediments deposited in a transgressive and regressive cycle. The sand and shale bed thickness vary irregularly. In the job planning phase, it is warned that glauconite in varying amounts may...

... calibration. The reservoir is characterized by low-resistivity pay zones, high matrix densities and standard log and core porosities of about 35 PU. The reservoir sands are fine to very fine grained, well sorted with abundant iron-rich glauconite and chlorite. The microporous glauconite reduces the reservoir...

... ABSTRACT NMR porosity and relaxation time measurements from an iron-rich. glauconitic sandstone reservoir show quantifiable effects of mineral iron content on NMR T2 relaxation times. This result has significant impact upon measuring irreducible water pore volume where the surface relaxation...

... ABSTRACT Glauconite is commonly found in the Lower Senonian of the Gulf of Suez (Nezzazat Group Matulla Formation) and the Egyptian Western Desert (Upper Bahariya Formation) in sufficient quantities to have an impact on density, neutron, Pe, and resistivity log response. Glauconite...
