Abstract: Window reaming and coring apparatus has a reamer connected in the middle of the tool by mechanical joints which permit the reamer to be displaced substantially parallel to the rest, of the tool body. The apparatus is lowered adjacent a pre-determined zone of interest and mills a parallel window along the edge of an existing wellbore into which the reamer is displaced. Once the reamer is fully displaced laterally into the window, the reamer and coring head can be rotated parallel to the wellbore, in the zone of interest for obtaining and retrieving a crescent-shaped core which has a significant cross section and length, enabling improved analysis of the wellbore lithography.

Title: Systeme frigorifique a fluide frigorigene double et methode connexe
Inventor: LESAGE GAETAN
IPC: F25B41/00
Filed: 2006-09-08
Granted: 2012-07-10
Abstract: Un système frigorifique à fluide frigorigène double fournit un cycle de réfrigération dans lequel un fluide frigorigène primaire refroidit un fluide frigorigène secondaire dans un évaporateur primaire dans un état partiellement surgelé, dans lequel une partie de fusion est surgelée. Le fluide frigorigène primaire absorbe ainsi une chaleur latente secondaire du fluide frigorigène secondaire, comprenant une chaleur latente de fusion exigée pour surgeler la partie de fusion. Le fluide frigorigène secondaire est subséquemment, au moins partiellement, dégelé dans un évaporateur secondaire par la réabsorption de la chaleur latente secondaire du matériau à proximité de l'évaporateur secondaire. L'évaporation dans l'évaporateur secondaire exige au moins une décongélation partielle de la partie de fusion, et, par conséquent, est au moins partiellement réabsorbée par le fluide frigorigène secondaire, augmentant ainsi la chaleur secondaire absorbée du matériau et facilitant la réfrigération. Le système fournit aussi des capacités de dégivrage et de récupération de chaleur.

Abstract: An instruction decoder 14 identifies, for each instruction, an operational block involved in the execution of the instruction and an associated heat release coefficient.  The instruction decoder stores identified information in a heat release coefficient profile 20. An instruction scheduler 16 schedules the instructions in accordance with the dependence of the instructions on data. A heat release frequency adder 32 cumulatively adds the heat release coefficient to the heat release frequency of the operational block held in the operational block heat release frequency register 22 as the execution of the scheduled instructions proceeds. A heat release frequency subtractor 34 subtracts from the heat release frequency of the operational blocks in the operational block heat release frequency register 22 in accordance with heat discharge that occurs with time. A hot spot detector 36 detects an operational block with its heat release frequency, held in the operational block heat release frequency register 22, exceeding a predetermined threshold value as a hot spot. The instruction scheduler 16 delays the execution of the instruction involving for its execution the operational block identified as a hot spot.
