Borehole imaging logs are logging and data-processing methods used to produce two-dimensional, centimeter-scale images of a borehole wall and the rocks that make it up. These tools are limited to the open-hole environment.
During such drilling, data is acquired from the drilling rig sensors for a range of purposes such as: decision-support to monitor and manage the smooth operation of drilling; to make detailed records (or well log) of the geologic formations penetrated by a borehole; to generate operations statistics and performance benchmarks such that ...

A log–log plot of y = x (blue), y = x 2 (green), and y = x 3 (red). Note the logarithmic scale markings on each of the axes, and that the log x and log y axes (where the logarithms are 0) are where x and y themselves are 1. Comparison of linear, concave, and convex functions when plotted using a linear scale (left) or a log scale (right).
The log gamma profile began gaining industrial popularity since 2005, when Arri released Arriflex D-20 which provided original Log-C gamma through HD-SDI video output, and further in 2008, when Sony released CineAlta F35 camera (and its 2005 Panavision Genesis sibling) with S-Log video recording on HDCAM-SR tape. Those camera releases boosted ...
The earliest and still most commonly used type of FITS data is an image header/data block. [citation needed] The term 'image' is somewhat loosely applied, as the format supports data arrays of arbitrary dimension—normal image data are usually 2-D or 3-D, with the third dimension representing for example time or the color plane. The data ...
The ESA/ESO/NASA FITS (Flexible Image Transport System) Liberator is a free software program for processing and editing astronomical data in the FITS format to reproduce images of the universe. Version 3 [ 1 ] and later are standalone programs; earlier versions were plugins for Adobe Photoshop .
Thomas Walker was born in London in 1805. [3] Before the age of ten he left home to find work in Stoke-on-Trent in the Potteries. He began his working life in the pottery industry, first as a labourer then later as a print assistant, when he revealed early signs of inventive skill by devising a rubber system for printing.
