| A system is provided for monitoring in the real time the wellbore pit volume to promptly determine the occurrence of a wellbore kick and take corrective action to minimize fluid influx volume and/or drilling fluid losses. A system includes one or more level sensors 22 which output signals to a pit volume totalizer 20 and then to a computer 26. Computer 26 may also receive signals from one or more fluid temperature sensors 40 and one or more fluid compressibility sensors 42. The output from the computer may be displayed in real time in various monitors 28, then also may be output to a permanent record 30. Computer 36 may also automatically activate the conventional alarm 32 to alert the drilling operator to the occurrence of a kick. Substantial savings in drilling time and cost may be realized according to the present invention, along with benefits of reduced environmental contamination and enhanced well safety. | ||||||

| 53 | Method for determining the profile of an underground hydrocarbon storage cavern | US14696389 | 2015-04-25 | US09669997B2 | 2017-06-06 | James N. McCoy |
| 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. | ||||||

| Microenergetic particles can be employed in hydraulic fracturing of oil or gas wells. By exciting the microenergetic particles, an operator performing a fracture job can better map the fracture process and/or increase the extent of fracturing over what can be accomplished using only pumps.
