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 ...

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 ...
A "mud man" is the drilling fluids technician responsible for formulating the mud, while a "mud logger" checks mud cuttings from the drill bit for traces of rock or oil and gas that provide a picture of conditions downhole. Negative Pressure test: A test performed to determine the integrity of wells.
The total gas, chromatograph record, lithological sample, pore pressure, shale density, D-exponent, etc. (all lagged parameters because they are circulated up to the surface from the bit) are plotted along with surface parameters such as rate of penetration (ROP), Weight On Bit (WOB), rotation per minute etc. on the mudlog which serve as a tool ...
Tracers are used in the oil industry in order to qualitatively or quantitatively gauge how fluid flows through the reservoir, [1] as well as being a useful tool for estimating residual oil saturation. Tracers can be used in either interwell tests or single well tests. [2]
Oil, gas and petrochemical processes are undertaken at specific temperatures. Measurement of temperature of fluids in the petrochemical industry is undertaken by temperature elements (TE). These can be Thermocouples or Platinum Resistance Temperature Detectors (RTDs). The latter are used for their good temperature response.
A RAND study in 2005 estimated that production of 100,000 barrels per day (16,000 m 3 /d) of oil (5.4 million tons/year) would theoretically require a dedicated power generating capacity of 1.2 gigawatts (10 billion kWh/year), assuming deposit richness of 25 US gallons (95 L; 21 imp gal) per ton, with 100% pyrolysis efficiency, and 100% extraction of pyrolysis products.
