摘要： Underground storage caverns are widely used for the bulk storage of petroleum products, in particular, crude oil. The caverns are accessed through a casing in a borehole down to the cavern. The lower end of the casing opens into an upper region of the cavern termed the chimney. The chimney provides a transition from the casing into the cavern body. The invention presents a process of injecting a gas into the well while measuring the gas pressure and optionally measuring the volume of injected gas. The gas drives down an interface between the gas and hydrocarbon liquid. By monitoring the rate of change of the gas pressure, and detecting a sudden decrease in the rate of change, it can be determined when the interface has been driven down to the region immediately below the bottom of the casing at the upper end of the chimney.

摘要： Underground storage caverns are used for the bulk storage of hydrocarbon liquids, such as crude oil and gases, such as natural gas. The cavern is accessed through a bore hole which has casing and, for some bore holes, internal tubing with an annulus between the casing and tubing. The upper end of the cavern has a roughly cylindrical region termed the chimney. In order to check it for physical integrity, it is necessary to measure the profile of the chimney. This is also referred to as conducting a survey of the cavern. The cavern typically has hydrocarbon liquid above brine up to the surface. An inert gas can be injected above the hydrocarbon liquid to form an interface. The profile is conducted by driving the gas/liquid interface downward with gas pressure to a reference level determined by sequentially transmitting acoustic pulses to locate the reference level. Gas is injected to increase the pressure by a predetermined value and thereby drive down the interface by a known distance. The volume of the gas injected is used together with the known distance to determine a profile of the chimney. The process of injection of gas to increase the pressure by the predetermined value and measurement of the volume is repeated sequentially to determine the chimney profile at progressively lower regions, thereby producing an extended profile of the chimney.

摘要： Underground storage caverns are widely used for the bulk storage of petroleum products, in particular, crude oil. These caverns can store millions of barrels of hydrocarbon liquid safely for long periods of time at low cost. The caverns are accessed through a casing in a borehole down to the cavern. The lower end of the casing opens into an upper region of the cavern termed the chimney. The chimney provides a transition from the casing into the cavern body. The lower end of the casing has a structure termed a casing shoe which seals the earth formation around the casing from the interior of the chimney. The chimney region needs to be periodically inspected to determine if it is stable. The salt structure of the cavern is subject to erosion and collapse of sections of the wall. Deterioration of the physical structure of the chimney can also lead to the opening of cracks which may allow the stored liquid to leak into the formations around the casing and the chimney. The invention presents a process of injecting a gas into the well while measuring the gas pressure and optionally measuring the volume of injected gas. The gas drives down an interface between the gas and hydrocarbon liquid. By monitoring the rate of change of the gas pressure, and detecting a sudden decrease in the rate of change, it can be determined when the interface has been driven down to the region immediately below the bottom of the casing at the upper end of the chimney. This determines a critical location for the interface. Further steps of injecting gas and measuring gas pressure are used to determine the profile of the chimney.

摘要： A method for real-time data acquisition and presentation of force, position, load, pressures, and movement within a subterranean well pumping system, such as an oil well. Data is gathered using sensors attached to a surface level pump drive and wellhead system. Well structural data and well production data are combined therewith to generate a real-time display of down-hole well operation, including animated graphics of the pump operation, including pump movement, rod and tubing stretch, fluid movement, gas compression, system forces, and fluid pressures. Liquid levels are tested using an acoustic liquid level instrument, and incorporated to improve well performance analysis.
