... Abstract When analyzing borehole image data, more is generally better. More sensors, higher resolution and multiple post-processing filters are typical strategies for ensuring that no important reservoir information is being missed. Handling large amounts of data can however be a hurdle...

...).

At approximately X560 by a fault with N-NW strike. The Western block showed meters MD...

... Abstract Sedimentary geometry on borehole images usually summarizes the arrangement of bed boundaries, erosive surfaces, cross bedding, sedimentary dip, and/or deformed beds. The interpretation, very often manual, requires a good level of expertise, is time consuming, can suffer from user bias...

...ABSTRACT ABSTRACT Borehole images provide many different texture features for facies analysis and natural fracture identification. However, classification of most of these features is achieved manually. The workflow proposed here is to implement geological "facial recognition" from borehole...

... ABSTRACT Borehole image interpretation aims to evaluate the dip magnitude and azimuth direction of geological features detected along the well and to classify them. Manual interpretation of borehole images can be time consuming and is sometimes affected by inconsistencies stemming from...

... ABSTRACT Deepwater reservoirs often consist of highly laminated sand shale sequences, where the formation layers are too thin to be resolved by conventional logging tools. To better estimate net sand and hydrocarbon volume in place, one usually needs to rely on high-resolution borehole image...

Borehole images using resistivity and density for fracture determination were also run along with advanced sonic tools acquiring Stoneley wave data for detection of fractures and determination of whether the fractures are open or closed. The borehole images were also used to detect the presence of vugs...
