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.
Exploring both Saturn and Titan, Saturn's mysterious moon. Name Christiaan Huygens (1629-1695) was a Dutch scientist who discovered Saturn's rings and, in 1655, its largest moon, Titan.Italian Jean-Dominique Cassini (1625-1712) discovered the Saturnian satellites Iapetus, Rhea, Tethys and Dione.he ESA Huygens probe is the first to land on a world in the outer Solar System-on the surface of Titan, Saturnâs largest moon. Data from Cassini and Huygens may offer clues about how life began on Earth. Launch 15 October 1997 (Titan-IVB/Centaur at Cape Canaveral, United States).
