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.
Hawking has devoted most of his life to studying these questions. Initially, cosmologists believed the holes were like a cosmic vacuum cleaner, sucking up everything in their path. Hawking revolutionized the study of the holes when he demonstrated in 1976 that, under the strange rules of quantum physics, once black holes form they start to evaporate away, radiating energy and losing mass in the process.
