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.
November 05, 2013.
