121 | A METHOD FOR DRYING A SUBTERRANEAN CAVERN | EP92908584.3 | 1992-03-26 | EP0577706B1 | 1996-09-25 | MAGTENGAARD, Jesper, Ricard; JENSEN, Preben |
A method is provided for reducing the water content of a natural or artificial subterranean cavern provided with (i) means for introducing a relatively dry gas into the cavern and (ii) means for withdrawing gas from the cavern. The gas-introduction means and the gas-withdrawal means each comprise a gas-transfer conduit having an open end opening to the cavern, the open end of one of the gas-transfer conduits being positioned lower than the open end of the other gas-transfer conduit, and the method in question comprises the introduction of relatively dry gas into the cavern via one of the gas-transfer conduits, and the withdrawal, via the other gas-transfer conduit, of gas having a higher water vapour content than that of the relatively dry gas which is introduced. The method is well suited to reduction of the water content of a cavern which is to be used for the storage of a fluid, such as a cavern for the storage of 'natural gas'. | ||||||

The invention provides caverns and methods for producing caverns in bedded salt deposits. In a preferred method, a first bore hole (19) is drilled into the salt formation (10) and a cavity (13) for receiving insolubles is leached from the salt formation (10). Thereafter, at a predetermined distance away from the first bore hole (19), a second hole (17) is drilled towards the salt formation. The drill drills through the salt formation in a horizontal direction until it instersects the cavity (13) for receiving insolubles. This produces a substantially horizontal conduit (20) from which solvent is controlledly supplied to the surrounding salt formation, leaching the salt and producing a concentrated brine which is removed through the first bore hole (19). Insoluble are collected in the cavity (13) for receiving insolubles. By controlledly supplying solvent, a horizontal cavern is produced with two bore holes (17 and 19) extending therefrom. | ||||||

Afin d'améliorer le débit de soutirage de gaz à partir d'une cavité saline de stockage de gaz accessible par un puits comportant un tubage (18) utilisé lors du remplissage, on découpe ce tubage par tronçons, en partant du bas, et on descend chaque tronçon en dessous de l'extrémité inférieure d'un cuvelage entourant le tubage. Pour cela, on utilise un outil de coupe (30) monté à l'extrémité inférieure d'un train de tiges tubulaires (28) et comportant des moyens d'ancrage (36) commandés par des impulsions de pressions dans une colonne d'eau remplissant le train de tiges. Les outils de coupe (40) sont actionnés séparément par une rotation et une translation d'une partie supérieure (38) de l'outil, commandées par le train de tiges. |

Un procédé de confinement de déchets solides, pâteux ou liquides dans une cavité souterraine creusée par lessivage dans le sel (2) et remplie de saumure (5) comprend les étapes suivantes : La densité dudit liquide tampon est inférieure à celle dudit mélange et ladite quantité de liquide tampon est telle que la hauteur libre (h) dudit liquide tampon (7) soit toujours supérieure à une hauteur prédéterminée. Le liquide tampon peut comprendre un solvant halogéné, par exemple un solvant chloré, et ledit liant peut contenir des cendres volantes d'incinération d'ordures ménagères. Le liquide tampon (7) et le mélange de liant et de déchets (10) sont de préférence introduits dans la cavité (1) au moyen d'un tube constitué d'éléments démontables (9) ayant chacun une hauteur (ho) inférieure à ladite hauteur prédéterminée. |

An environmentally acceptable gas is provided, under pressure, in the annulus (46) of a casing arrangement which connects a wellhead to an underground storage zone (40) containing stored product. Monitoring of the gas permits detection of leaks that might occur through casing leakage to an unsealed overburden. Leak detection and product loss prevention can be conducted without deleterious environmental impact. |

Pour obturer l'ouverture d'un puits (1) débouchant dans le plafond d'une cavité souterraine (2), on utilise une pièce (4) en forme de clef de voûte, percée en son milieu pour le passage de canalisations (31,32), puis on coule des ciments appropriés pour solidariser l'ensemble et l'on remplit le puits. |

Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable. | ||||||

A cavern pressure control method includes storing compressible and possibly incompressible fluids in an underground storage volume, removing a portion or introducing additional incompressible fluid into the underground storage volume, possibly removing a portion or introducing additional compressible fluid into the underground storage volume, thereby producing a net pressure increase rate (Pinc) within the underground storage volume, wherein Pinc is maintained at less than a predetermined maximum increase value (PImax). | ||||||

A method and arrangement are proposed for injecting CO2 into a subterranean aquifer for storage therein. In order to reduce the effects of water evaporation from brine in the aquifer when dry CO2 is injected into the aquifer, the CO2 is supplied mixed with a salt-lean fluid, i.e. a fluid that contains a low concentration of ions that can precipitate out as salts. The mixing may take place at the wellhead, with the CO2 salt-lean fluids supplied via separate low-grade material pipelines. The proportion of CO2 and salt-lean fluid in the mixture is such as to obtain a CO2 composition that is saturated with salt-lean fluid at the site of injection into the aquifer. By injecting saturated or “wet” CO2, less water is evaporated from the brine and the salt precipitation is greatly reduced, so keeping the pore spaces clear and providing an increased accessible pore volume for CO2 storage. | ||||||

The present invention relates to an arrangement for storing thermal energy, comprising a shaft (1) and at least one tunnel (2), the shaft (1) and the at least one tunnel (2) being in fluid communication with each other. The tunnel (2) comprises at least a first (2a), a second (2b), and a third (2c) tunnel section. The second tunnel section (2b) is arranged between and connected to the first (2a) and third (2c) tunnel sections. The second tunnel section (2b) is sealed off at an end (4) connected to the third tunnel section (2c), and the third tunnel section is further connected the shaft (1). The shaft (1) and first (2a) and third (2c) tunnel sections are adapted for holding fluid for thermal storage. The second tunnel section (2b) is adapted for use as an expansion space should a volume of the fluid expand beyond a volume of the shaft (1) and the first (2a) and third (2c) tunnel sections. The arrangement further comprises a first transfer means (5) for passing the expanded fluid volume from the shaft (1) and/or the third tunnel section (2c) temporarily into the first tunnel section (2a), and a second transfer means (6) for passing the expanded fluid volume from the first tunnel section (2a) to the second tunnel section (2b). | ||||||

A method for providing the recharge of water into underground aquifers while preventing the mobilization of trace metals. The recharge water may be used for storage and subsequent withdrawal, or to regain or increase the long term beneficial use of an aquifer. The recharge water may be also be used to influence the groundwater flow in the aquifer. Water is treated and recharged by the addition of a small amount of a sulfide compound to remove dissolved oxygen and prevent dissolution of negative valence sulfur bearing minerals, such as pyrite, in the subsurface. The recharged water may increase the pressure head in the aquifer, alter the groundwater flow pattern to prevent the encroachment of objectionable quality water, or to segregate water of different quality. The recharge water may be fresh or brackish depending on the specific objectives of the application. |
