WST – well seismic tool (checkshot [citation needed]) WSTL – well site test log; WSU – well service unit; wt – wall thickness; WT – well test; WTI – West Texas Intermediate benchmark crude; WTR – water; WUT – water up to; WV – wing valve (from a christmas tree [citation needed]) WVS – well velocity survey; WWS – wire ...
A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...
A MLS facilitates the collection of ground-water samples and measurement of hydraulic heads from many more discrete depths than can be obtained using typical well clusters or nests. A MLS facilitates the collection of subsurface head and chemical data over time, which is something that cannot be accomplished using "one-time" profiling tools ...
A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
Regularly, for example once a month per well, the flow from one and only one selected well is led into the test separator for determining well flow rate for the selected well. [3] The separator divides the flow from the well into the streams of individual products which typically are oil, gas and water, but may include natural-gas condensate ...
Systems installed in well casing to read formation pressure directly, suspended systems, and systems built in coil (continuous) tubing are also available. The data that PDGs provide are useful to reservoir engineers in determining the quantities of oil or gas contained below the Earth's surface in an oil or gas reservoir and also which method ...

Annular BOPs are typically located at the top of a BOP stack, with one or two annular preventers positioned above a series of several ram preventers. An annular blowout preventer uses the principle of a wedge to shut in the wellbore. It has a donut-like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs. The packing ...
