In computational geometry and computer science, the minimum-weight triangulation problem is the problem of finding a triangulation of minimal total edge length. [1] That is, an input polygon or the convex hull of an input point set must be subdivided into triangles that meet edge-to-edge and vertex-to-vertex, in such a way as to minimize the ...
FLOT – flying lead orientation tool; FLOW – flow and buildup test report; FLRA – field-level risk assessment; FLS – fluid sample; FLT – fault (geology) FLT – flying lead termination; FLTC – fail locked tending to close; FLTO – fail locked tending to open; FMD – flooded member detection; FMEA – failure modes, & effects analysis
A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. Deadweight testers are secondary standards which means that the pressure measured by a deadweight tester is defined through other quantities: length, mass and time.
Drill stem testing is an oil and gas exploration procedure to isolate, stimulate and flow a downhole formation to determine the fluids present and the rate at which they can be produced. The main objective of a DST is to evaluate the commercial viability of a zone's economic potential by identifying productive capacity, pressure, permeability ...

The measuring minimum level starts from a complete covering of the measuring element near the head end of the level sensor. Filling levels below the level probe are not detected. Depending on the application and mounting height, it is therefore necessary to adjust the level in the evaluation unit to the respective mounting height with an offset ...
Induction tools therefore give best results when mud resistivity is high with respect to formation resistivity, i.e., fresh mud or non-conductive fluid. In oil-base mud, which is non conductive, induction logging is the only option available. Until the late 1950s electric logs, mud logs and sample logs comprised most of the oilman's armamentarium.
The fuel level output for these senders can be ratiometric voltage or preferable CAN bus digital. These sensors also fail-safe in that they either provide a level output or nothing. Systems that measure large fuel tanks (including underground storage tanks) may use the same electro-mechanical principle or may make use of a pressure sensor, [ 9 ...
