In an oil / gas reservoir the oil essentially floats on water and the gas floats on oil. The top seal prevents the oil and gas escaping giving rise to the pressure configuration as shown. The "pressure kick" at the top seal (1) is contained when drilling by the drilling mud. (c) Co...
Underwater overpressure monitoring was required for each blast and peak overpressures measured 10 ft (3.1 m) above the river bottom 140 ft (42.7 m) from the closest blast hole were not to exceed 70 psi (483 kPa) with a cautionary level of 40 psi (276 kPa). Specifications required ...

a pressure sensor measures the pressure by converting it into an electrical signal. Then it records this voltage for later analysis. We do this by placing the diaphragm underwater. Next, we measure how it deforms under static or dynamic pressure force. ...

(for example 34° F.), with the lower temperatures occurring most frequently in subsea wells with a considerable depth of water above the well. During production from the reservoir, produced fluids pass through the production tubing at significantly higher temperatures. Temperatures in the range of...
16. An apparatus for removal of surface coatings from a magnetically tractive metallic structure by ultra-high pressure water, said apparatus comprising: a platform constructed and arranged to magnetically adhere to said metallic structure; at least one ultra high pressure nozzle positioned upon said ...
This pressure sensor can measure up to 30 Bar (300m water depth) with a depth resolution of 2mm. It is an ideal choice for ROVs, AUVs, remote sensors, and underwater instrumentation. Compatible with ArduSub on the BlueROV2 and with Arduino and Raspberry Pi devices. ...
This paper presents a disturbance-observer-based sliding mode control strategy for an underwater electro-hydrostatic actuator, particularly considering that electro-hydrostatic actuators (EHAs) significantly suffer from sea pressure disturbance, which makes it hard to achieve high-precision position control....
