Patent number: 9885797Abstract: An acoustic logging tool is disposed in a wellbore during an acidizing operation. Measurements are made using the acoustic logging tool on a region of a formation penetrated by the wellbore and being subjected to the acidizing operation. An acoustic anisotropic property of the formation is inferred at one or more depths of investigation within the region using the measurements, and a wormhole porosity and/or an orientation of one or more wormholes resulting from the acidizing operation is determined. Acidizing operation management decisions may be made based on the determined wormhole porosity and/or orientations of the wormholes. An acidizing operation management decision may be to maintain, increase, or decrease an acid injection rate. Measurements made may include the velocity of an acoustic wave propagating through the formation and the acoustic anisotropic properties of fast waves and slow waves. The acoustic anisotropic properties of the formation generally depend on rock stiffness.Type: GrantFiled: November 21, 2014Date of Patent: February 6, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Mohammed Badri, Reza Taherian

Patent number: 9861755Abstract: The present invention relates to a torsion spring driven injection device for delivering multiple set doses of a liquid drug from a cartridge by moving a plunger forward inside the cartridge. The torsion spring (134) applies a rotational torque onto a drive member (120) engaging a piston rod (115) which is then driven forward by this rotation. The piston rod driver can be coupled and de-coupled from the torsion spring mechanism. In the de-coupled position, the piston rod driver is freely rotatable and can thus rotate if the piston rod is moved axially. A further torsion arrangement (124) is preferably provided such that a torque is build up between the piston rod driver and the housing whenever the piston rod is moved backwards. This torsion arrangement urges the piston rod driver to rotate in a direction bringing the piston rod forward into abutment with the plunger.Type: GrantFiled: October 14, 2013Date of Patent: January 9, 2018Assignee: Novo Nordisk A/SInventors: Willem van der Beek, Steffen Hansen, Simon Roervig, Simon Munch Pedersen, Roger Harrington

Patent number: 9849250Abstract: A drive assembly for a drug delivery device comprises a rotation member being configured to be rotated in a first direction during setting of a dose of a drug and to be rotated in a second direction during delivery of the dose, a drive component being configured to follow rotational movement of the rotation member in the second direction during delivery of the dose and a stop member being configured to prevent rotational movement of the drive component in the first direction. The drive component comprises a first drive part and a second drive part, coupled to each other such that relative rotational movement of the first and second drive parts is prevented and relative axial movement is permitted.Type: GrantFiled: August 23, 2016Date of Patent: December 26, 2017Assignee: Sanofi-Aventis Deutschland GmbHInventors: Christopher James Smith, Stephen David Butler, Mark Philip Horlock

Patent number: 9731068Abstract: The invention concerns a connection device for connecting a first reservoir with a second reservoir, having a first section (11) for arranging the first reservoir (5) closed with a seal (51); a second section (12) for arranging the second reservoir; and a piercing element (2) which penetrates with a piercing end (21) the seal (51) of the first reservoir (5) when the first reservoir (5) is arranged at the first section (11). According to the invention, the piercing element (2) can be moved from a first position into a second position, wherein it blocks in the first position a flow connection between the first and the second section (11, 12), while in the second position it allows for a flow connection between the first and the second section (11, 12).Type: GrantFiled: February 21, 2012Date of Patent: August 15, 2017Assignee: Fresenius Vial SASInventor: Francois Rochette
