Webwater salinity, lithology, and continuity of the bedding can often be deduced. Borehole electric logs are also the best source of control for surface electrical surveys by providing subsurface layer resistivities. Electric log correlation of continuous layers from borehole to borehole is relatively simple. The interpretation of physical Webreferred to as slowness, is the reciprocal of velocity. Lithology and porosity affect ∆t. Dense, consolidated formations characterized by compaction at depth generally result in a faster (shorter) t while fluid-filled porosity ∆ results in a slower (longer) ∆t. Measurements are also uniquely affected by formation and borehole conditions. raycasting unrealWeb29 mrt. 2024 · Tight gas makes up a significant portion of the natural gas resources.
