Title: Bormotordrivenhet for hoy temperatur med sykloidalt reduksjonsgir
Inventor: HUMMES OLOF
IPC: E21B4/02
Filed: 2013-05-06
Abstract: En bunnhullsammenstilling har en borkrone som drives av en borehullturbin. Turbinhastigheten reduseres ved hjelp av sykloidal utveksling som ikke krever noen temperatursensitive forseglinger når driftstemperaturene i noen anvendelser overstiger 350 grader F. Den utgående akselen på det sykloidale reduksjonsgiret går gjennom et lager før forbindelse med borkronen eller tilhørende opprømmer. Det drivende fluidet kan være boreslammet. Boret kan drives ved ønskede hastigheter som 50-300 o/min, mens hastighetsreduksjonsforholdet kan være i størrelsesordenen 10 til 1 eller mer. Denne drivenhetsammenstillingen kan erstatte borehullplasserte motordrivenheterav Moineau- type som har temperaturbegrensninger på grunn av at det brukes gummi i statorene.

Title: Kutting av en rørkonstruksjon med et forseglet ringrom og fluidstrømning for fjerning av avskjæringer
Inventor: GUIDRY CHRISTOPHER W
IPC: E21B23/01
Filed: 2013-11-05
Abstract: Et kutt-og-dra-spyd er konfigurert til å oppnå flere grep på en rørkonstruksjon som skal kuttes under spenning. Slippene manøvreres mekanisk ved hjelp av drivhoder for å holde en del av sammenstillingen mens mandrellen manipuleres. En ringformet forsegling er plassert i kombinasjon med slippene for å tilveiebringe kontroll over brønnen i løpet av kuttingen. En intern omføring rundt forseglingen kan være i åpen posisjon for å tillate sirkulasjon i løpet av kuttingen. Omføringen kan lukkes for å kontrollere et brønnspark med mekanisk manipulering mens forseglingen forblir på plass. Hvis rørkonstruksjonen ikke frigjøres etter en første kutting, kan spydet bli utløst for å frigjøres og plasseres på et annet sted. Mandrellen er åpen for omløp mens slippene og forseglingene plasseres og kuttingen utføres. Avskjæringene filtreres før de går inn i omføringen for å holde avskjæringene ute av utblåsingssikringene.

Title: Method of and apparatus for granulating precipitates from petroleum processing processes
Inventor: MORETTA JON C
IPC: C10L5/40
Filed: 2000-11-23
Abstract: Disclosed are a method and apparatus for making substantially spherical, homogenous petroleum resid pellets having a size range between 0.1 and 10 mm, a penetration of essentially 0, a softening point temperature from about 200 DEG  to about 400 DEG F, a residual water content of from 0.1 to 10 weight percent, and a sulfur content less than 10 weight percent. The process includes feeding the material in a molten state to a rotating prilling head to discharge the material into free space at an upper end of a pelletizing vessel having a diameter larger than a throw-away diameter of the discharged material, allowing the discharged material to break apart, form into substantially spherical liquid pellets, and fall downwardly into a liquid spray and/or bath to solidify the pellets. The apparatus has an upright pelletizing vessel with an upper prilling zone, a sphere-forming zone below the prilling zone, a cooling zone below the sphere-forming zone, a bath below the cooling zone, and a prilling head in the prilling zone rotatable along a vertical axis and having a plurality of discharge orifices for throwing molten material radially outwardly. A vertical height of the sphere-forming zone is sufficient to allow material discharged from the prilling head to form substantially spherical liquid pellets. Nozzles are provided for spraying water inwardly into the cooling zone to cool and at least partially solidify the liquid pellets to be collected in the bath. Also disclosed is pretreatment of a soft resid (softening point temperature below 200 DEG F) by air oxidation to produce a hard resid suitable for feed to the prilling head. <IMAGE>
