Geographical survey of the earth during early geological periods
A map that shows the distribution of sedimentary environments at a specific time in the past. These maps are made by studying the rock record to correlate rock units that were deposited at the same time, then relating rock characteristics to specific sedimentary environments
The climate of a given area at a specific time in the past. Paleoclimates can be read from the rocks much as areas with different types of climates produce sediments with specific characteristics today
Rocks from the Paleocene era that were created between 65 to 54 million years ago
When the flow of oil or gas completely fills the pipeline. This term contrasts to Slackline
Liquid, usually salt water or oil, but sometimes mud, used in a well when a packer is between the tubing and the casing. Packer fluid must be heavy enough to shut off the pressure of the formation being produced, and should not stiffen or settle out of suspension over long periods of time, and must be non-corrosive
A device that can be put into the wellbore with an initially smaller diameter that then expands to seal the wellbore. (2) A downhole device used in nearly every completion to isolate the annulus from the production conduit, enabling controlled production, injection or treatment
A molecule made up of three atoms of oxygen. In the stratosphere, it occurs naturally and provides a protective layer shielding the Earth from ultraviolet radiation and subsequent harmful health effects on humans and the environment.
