... Abstract Proximity Sensing was recently proposed as way to simultaneously increase both range and resolution in cross-well EM tomography. The approach is applicable to reservoirs with resistive seals. Earlier reports were based on Finite Element Models (FEM) of layered structures...

... and absolute permeability are two essential properties that can be derived from grayscale images. These properties represent storage and flow capacity of the rock. Some rock samples, particularly carbonate rocks have complex micro-structures at several length scales. Due to limited image resolution, 3D images...

... a progressive increase in the along hole resolution of LWD images, and today's highest resolution tools achieve nominal along hole resolutions of approximately 0.5-in. with full 360° azimuthal borehole wall coverage. The focus of this study is the high-resolution LWD resistivity images recorded downhole...

The integration layer interrogates real time data on a continuous basis to detect reservoir behavior trends and anomalies. Reservoir engineers are alerted to such anomalies for further analysis and resolution...

... targeted high frequency ranges in the spectrum. The dip steered filters trade spatial resolution for increased S/N, but only in targeted frequency bands that are boosted during the subsequent whitening process. The S/N of the low frequencies can be improved using a similar process prior to acoustic...

.... Although medical CT-scanners have seen constant improvement in speed since their inception in the early ‘70s, the spatial resolution has not improved from the typical 350-450 mm range. Typical pore sizes of reservoir rocks vary from sub-micron to few microns and therefore the oil industry has...

... Abstract Walkaway VSP (WVSP) data plays a major role in reservoir delineation and characterization. High-resolution VSP data can be integrated with surface seismic data to provide detailed descriptions of formation properties and identification of reservoir compartments, which are not possible...

...). If a reasonable sample size (5mm-1cm) can be obtained, micro-CT scanning can be undertaken at resolutions of 2-4 microns. Using advanced image analysis techniques the pore structure and an equivalent pore network model of the rock can be extracted. This model retains key properties of the pore space of the rock...

... Arabian oil and gas fields. These cuttings are a few mm across and are imaged with a resolution of 3 to 12 microns. Hence, the details of the three-dimensional pore space can be clearly seen. A maximal ball algorithm 1 , 2 is used to extract a topologically equivalent pore-throat network: the largest...

... and services currently provided have various limitations. The resolution of the logging tools has not come below one foot. The depth-of-investigation of almost all the logging tools has not exceeded a couple of feet into the formation. Data acquisition in most of the logging tools has limited speed. Logging...
