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.
Tank leak detection is implemented to alert the operator to a suspected release from any part of a storage tank system, what enables to prevent from soil contamination and loss of product. In many countries regulated UST are required to have an approved leak detection method so that leaks are discovered quickly and the release is stopped in time.
Well completion is the process of making a well ready for production (or injection) after drilling operations. This principally involves preparing the bottom of the hole to the required specifications, running in the production tubing and its associated down hole tools as well as perforating and stimulating as required.
The emission from a leaking natural gas well off the Texas coast could no longer be seen from shore by Wednesday and was down to about 5 percent of what it was the day before, officials said.
A permanent downhole gauge (PDG) is a pressure and/or temperature gauge permanently installed in an oil or gas well. [1] These gauges are typically installed in the tubing in the well and can measure the tubing pressure, annulus pressure, or both.

It is often helpful to visualize the well as a U-shaped tube. Column Y of the tube represents the annulus, and column X represents the pipe (string) in the well. The bottom of the U-tube represents the bottom of the well. In most cases, fluids create hydrostatic pressure in both the pipe and annulus.
Bottom-hole pressure (BHP) is the pressure at the bottom of a well. The pressure is usually measured at the bottom of the hole. This pressure may be calculated in a static, fluid-filled wellbore with the equation: BHP = D × ρ × C, where BHP = bottom-hole pressure D = the vertical depth of the well
