Patent CA-2781868-A1 (CA)
Inventor: CHENG YAO-CHOU
IPC: E21B43/30
Filed: 2010-10-19
Abstract: Method for determining one or more optimal well trajectories and a drill center location for hydrocarbon production. A well path and drill center optimization problem (55) is solved in which one constraint is that a well trajectory must intersect a finite size target region (61) in each formation of interest, or in different parts of the same formation. The finite target size provides flexibility for the optimization problem to arrive at a more advantageous solution. Typical well path optimization constraints are also applied, such as anti-collision constraints and surface site constraints (62).

Title: Polystyrene/polyethylene oxide copolymer cell size enlarger for foam
Inventor: DELAVIZ YADOLLAH
IPC: C08J9/12
Filed: 2011-01-27
Abstract: Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an infrared attenuating agent, and a polystyrene/polyethylene oxide copolymer are provided. In exemplary embodiments, the blowing agent contains an HFC. The maleic anhydride-styrene copolymer grafted with polyethylene oxide increases the cell size of the polymer foam and offsets or even negates the decreased cell size caused by an HFC blowing agent and/or infrared attenuating agents. In addition, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.

The system includes a first sub-system that stores and feeds the VSTs to a vibratory bowl where they are initialized. A second sub¬ system transfers the tags from the vibratory bowl and sorts the tags assuring the tags are reusable rather than disposable tags. A third sub-system tests the reusable tags to assure compliance with select parameters such as frequency and amplitude. If the reusable tags comply with the parameters then they are deemed activatable. The system may also automatically sort and count the accepted and rejected tags. The system disclosed herein is capable of testing VSTs at a high speeds, e.g., up to 150 units per minute, with the required quality level and reliability.

Title: Apparatus and method for fracturing a well
Inventor: CAMPBELL SEAN PATRICK
IPC: E21B34/14
Filed: 2011-08-23
Abstract: Apparatus and methods are provided for fracturing a well in a hydrocarbon bearing formation. The apparatus can include one or more valve sub-assemblies assembled into a tubing string inserted into an unlined well. The valve sub-assembly can include a sliding piston initially pinned in place to seal off ports that provide communication between the interior of the tubing string and a production zone of the formation. A ball can be inserted into a tubing string and moved along the tubing string by injected pressurized fracturing fluid until the ball sits on a valve seat of a valve sub-assembly coupled to the sliding piston to close off the tubing string below the valve. The force of the fluid forces the piston downwards to shear off the pins and open the ports. Fracturing fluid can then exit the ports to fracture the production zone of the formation.

Title: Aptamer labelled with f-19 nucleus for targeted molecular imaging by mri
Inventor: GUENTHER RALF
IPC: A61K49/12
Filed: 2011-12-12
Abstract: Magnetic Resonance Imaging, usually based on 1H as the magnetic nucleus, is an important diagnostic technique that is commonly used in hospitals for the diagnosis of disease. MRI allows for the non- invasive imaging of soft tissue with a superb spatial resolution. Magnetic Resonance Imaging based on 19F instead of 1H opens up new diagnostic possibilities. The 19F nucleus has a high gyromagnetic ratio (40 MHz/T) and a natural isotopic abundance ratio of 100%. In the human body, 19F containing structures are exclusively present in the form of solid salts in e.g. teeth and bones. As a consequence, the J2 relaxation times of the endogenous 19F atoms are extremely short and the MR signal is hardly detectable, in other words, the lack of endogenous,19F-based structures with relatively high transverse relaxation times assures a very low background MR signal. Therefore, exogenous 19F-based MRI contrast agents allow for "hot spot" imaging in a way similar to other techniques such as PET (positron emission tomography). As a useful extension of its diagnostic use, MRI is also proposed for the monitoring of the delivery of bio-active agents such as therapeutic or diagnostic agents. I.e., MRI can not only be used for treatment planning, but also to control local drug delivery under image guidance.
