Wireline Operations. This is part of the Oil and Gas Production Series. Many of todayâs most vital oilfield operations depend directly on the use of wireline, a strong, thin length of wire cable mounted on a powered reel. Wireline is particularly important during completion and production. Field operators can run anything from a basic downhole directional survey to the most delicate gamma ray formation log on wireline.
The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.
Interestingly enough it has now been shown, by one Stephen Hawking, that the matter inside a black hole is not completely isolated from the rest of the universe and that given a sufficient length of time black holes will gradually dissolve by radiating away the energy of the matter that they contain.he first real study into the phenomenon was undertaken by Karl Schwarzchild in 1916 who derived an equation for the Schwarzchild Radius of a black hole (Rs = GM / c^2, where Rs is the Schwarzchild radius, G is Newton's gravitational constant, M is the mass of the blackhole and c the speed of light).
