Mudlogging: drill cuttings analysis. Cuttings are the small pieces of rock that are chipped away by the bit while a well is being drilled. The rock fragments are transported by the mudstream from the bit to the surface where they can be “caught” and analyzed (see Land rigs ). Drill cuttings are important because they are often the only ...{ "version": "5.3.2", "themes": [ { "name": "Cerulean", "description": "A calm blue sky", "thumbnail": "https://bootswatch.com/cerulean/thumbnail.png", "preview ...{ "currentVersion": 10.91, "id": 65, "name": "Geological surface formation", "type": "Feature Layer", "description": "", "geometryType": "esriGeometryPolygon ...Uluru (also known as Ayers Rock and pronounced: ool-or-roo) is a large natural sandstone rock formation located in the Northern Territory of Australia.
