... pressure, in-situ stress, and lithology are thus required for safe drilling and optimal development in such reservoirs. In the Permian Basin, changes in lithology occur over vertical depths that cannot be resolved by seismic velocities obtained by kinematic analysis, as these have poor vertical resolution...

... correction technique is not implemented in real time, leaving the measurement vulnerable to borehole environmental effects and mainly standoff. Standoff should be limited to 0.25 in for light mud, leading to a 0.05 g/cm 3 correction ofbulk density. While the vertical resolution of Gamma-Gamma density...

... Abstract Determining effective porosity and permeability (filtration capacity properties-FCP) of reservoir rocks represented by thinly laminated depositional sequences is a challenging task. The vertical resolution of most logging tools is coarser than the thickness of individual lamina...

... The strategy in developing the new generation array laterolog tool is to devise a system that has (1) less borehole effect, (2) high vertical resolution, and (3) several properly distributed radial depths of investigation. The Multi Laterolog configuration, shown in Figure 1 , consists of a 14...

Such tools require increased levels of signal averaging in high salinity environments to increase the SNR of the data...

... the permeability of the sands (as opposed to that of the sand-shale system). Formation evaluation in thin sand-shale laminations starts with their detection. NMR vertical resolution is mainly controlled by the antenna aperture, that is, in the case of a high-resolution antenna, 6 in. or 15 cm. Within...

.... When a detector passes a longer interval of rock for each acquisition period, its vertical resolution is degraded. For azimuthally sectored data, this is even more of an issue, as bedding features within a sample period get blurred. The objective of the study is to develop a methodology to optimize...

The inversion algorithm effectively combines the high vertical resolution of wireline logs with the relatively dense horizontal coverage of 3D pre-stack seismic amplitude data...

.... Semblance processing is robust and provides reliable results in most cases but its vertical resolution is linked to the length of the tool array. Practically, it means it is not possible to detect beds that are smaller than a tool's array length. Hence, it can be difficult to compare slowness logs...

Frequency domain filtering using fast Fourier transforms has been used in the past to eliminate random noise using low pass filters and to determine the vertical resolution of logging measurements.

... Abstract The vertical resolution of continuous, multi-frequency NMR logs largely depends on the length of the stacking interval. Several factors determine the stacking length, such as the number of Carr-Purcell-Meiboom-Gill (CPMG) echo trains that are stacked to improve signal-to-noise ratio...
