The measured depth is the length of the well including any angled or horizontal sections. Consider two wells, X and Y. Well X has a measured depth of 9,800 ft and a true vertical depth of 9,800 ft while well Y has measured depth of 10,380 ft while its true vertical depth is 9,800 ft.
As technology has advanced, more modern drillers have better control of the overall well. Oil well control is the management of the dangerous effects caused by the unexpected release of formation fluid, such as natural gas and/or crude oil, upon surface equipment of oil or gas drilling rigs and escaping into the atmosphere.
Casing Diameters of a Borehole Casing Diagram premium gas tight connections on a casing string. Casing is a large diameter pipe that is assembled and inserted into a recently drilled section of a borehole. Similar to the bones of a spine protecting the spinal cord, casing is set inside the drilled borehole to protect and support the wellstream.
Well depth values from the wireline loggers operation are referred to as "logger's depth". The loggers depth are typically considered more reliable than the drillers depth. The differences between loggers and drillers depths are due to different stretch in the drilling string when drilling, and the wire line entered into the bore hole during ...
CHK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system) CHKSR – checkshot survey report; CHKSS – checkshot survey log; CHOPS – cold heavy oil production with sand; CHP – casing hanger pressure (pressure in an annulus as measured at the casing ...
In 1983, the Denver Broncos went on the road to Seattle and lost a wild-card playoff game 31-7. There was a rookie quarterback named John Elway who played that day. Bo Nix, one of Denver's most ...
When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids. The surface pressure control is provided by a Christmas tree, which is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production.
President-elect Donald Trump dismissed any suggestion that he’s being usurped by his high-profile billionaire ally Elon Musk during a speech at AmericaFest.
