The acronym TVDSS is commonly used in the oil industry to represent TVD minus the elevation above mean sea level of the depth reference point of the well. The depth reference point is the kelly bushing in the United States and a few other nations, but is the drill floor in most places.
The kelly drive is #19. A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table. This bushing is rotated via the ...
KB – kelly bushing; KBE – kelly bushing elevation (in meters above sea level, or meters above ground level) KBG – kelly bushing height above ground level; KBUG – kelly bushing underground (drilling up in coal mines, West Virginia, Baker & Taylor drilling) KCI – potassium chloride; KD – kelly down; KMW – kill mud weight
In fact, Kelly Ripa's net worth is $120 million to be exact. While she's best known for being a television personality, the New Jersey native has quite the extensive (and impressive) resume. The ...
In this simple diagram of a drilling rig, #20 (in blue) is the rotary table.

Donald Trump will be sworn in as president in the Rotunda of the U.S. Capitol on Monday, after the forecast bitter cold prompted planners to move the ceremony under the building's neoclassical ...
Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the United States Coast and Geodetic Survey [2] and used to measure the elevation of a point above and depression below mean sea level (MSL).
Maximum elevation figure (MEF) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area. It is of interest to pilots, who want to be aware of the highest mountain peaks and tall towers nearby, so that they can fly above them to avoid controlled flight into ...
