Title: Procede de fracturation de multiples zones a l'interieur d'un puits
Inventor: POTAPENKO DMITRY IVANOVICH
IPC: E21B43/17
Filed: 2012-07-28
Abstract: L'invention porte sur un procédé de fracturation de multiples zones à l'intérieur d'un puits de forage formé dans une formation souterraine qui est mis en uvre par formation de passages à écoulement traversant dans deux ou plus de deux zones à l'intérieur du puits de forage qui sont espacées les unes des autres le long de la longueur d'une partie du puis de forage. Les passages à écoulement traversant à l'intérieur de chaque zone ont différentes caractéristiques découlant de l'orientation des passages à écoulement traversant dans des directions dans chacune des deux ou plus de deux zones par rapport à une direction sélectionnée pour fournir des différences dans des pressions d'initiation de fracture à l'intérieur de chacune des deux ou plus de deux zones. Un fluide de fracturation est introduit dans le puits de forage dans un traitement de fracturation. Le fluide de fracturation dans le traitement de fracturation est délivré à une pression qui est supérieure à la pression d'initiation de fracture de l'une des deux ou plus de deux zones pour faciliter la fracturation de ladite une ou des deux ou plus de deux zones tout en restant inférieure à la pression d'initiation de fracture d'une quelconque autre zone non fracturée des deux ou plus de deux zones. Le procédé est répété pour au moins l'une ou plusieurs des zones non fracturées des deux ou plus de deux zones.

Title: Processes for fracturing a well
Inventor: SNIDER PHILIP M
IPC: E21B43/26
Filed: 2012-06-19
Abstract: Processes and systems for fracturing a formation are disclosed. Tools that may be selectively opened and closed are positioned on a tubular liner that in turn is positioned within a subterranean well bore. Separate pairs of packers are also attached to and positioned along the tubular liner so as to straddle each tool. Fracturing fluid is pumped from the surface through the tubular and open tool and past a pair of packers at a temperature and injection rate which causes contraction of the tubular liner. Thereafter, the velocity of the fracturing fluid is sufficient to set the pair of packers adjacent the open tool. Continued pumping of fracturing fluid is directed by the set packers into the adjacent subterranean environs at a pressure sufficient to fracture the subterranean environs.

Patent CA-2862786-A1 (CA)
Title: Determining position of underwater node
Inventor: GOSLING HARRY GEORGE DENNIS
IPC: G01S5/30
Filed: 2013-02-28
Abstract: A method of determining the position of an underwater node. The positions of three or more transmitters are determined. Each transmitter transmits at least four pulses, wherein a time difference between each pulse and a previous one of the pulses is proportional to a respective co-ordinate of the position of the transmitter. The pulses are received at the underwater node and decoded by measuring the delays between them, thereby determining the co-ordinates of the transmitters. The range of each transmitter relative to the underwater node is also determined. Finally the position of the underwater node is determined in accordance with the co-ordinates and ranges. Any errors in the measurements of the delays between the pulses only translate into small errors in the determined position because of the proportionality between the delays and the coordinates. Therefore if there is a gradual decrease of signal-to-noise ratio then the accuracy of the position estimate also degrades gradually. Also, the use of pulse position modulation provides a low computation overhead in decoding and encoding.

Abstract: An object launching apparatus for a well has a housing, a flow mandrel, and a cage. The flow mandrel is disposed in the housing's internal chamber, and a flow passage in the mandrel communicates flow from the housing's inlet to the mandrel's flow port, which in turn communicates with the housing's outlet. The cage is disposed in the internal chamber and defines pockets for holding the objects. A motor and shaft move the cage in the housing relative to the mandrel's flow port so the cage's pockets can be selectively positioned in communication between the mandrel's flow port and the housing's outlet. This allows any of the object(s) held in the positioned pocket to be launched into the flow to the well. Preferably, the motor rotates the shaft so the cage can ride linearly along the shaft's thread and the cage can rotate through a cammed engagement with the housing.

Abstract: A yoyo capable to be electrically accelerated when held by hands, characterized in that, it comprises two spinning bodies (1), a connector (2) connecting the two spinning bodies (1) as a whole, side shaft sleeves (3) provided at center positions of outer sides of the spinning bodies (1), an electrical acceleration mechanism provided inside the spinning bodies (1), and a bearing (4) disposed between the two spinning bodies (1) for winding a yoyo string. The electrical acceleration mechanism is connected to the spinning bodies (1). By pressing the side shaft sleeves (3), the electrical acceleration mechanism operates and thus drives the spinning bodies (1) to spin simultaneously. The side shaft sleeves (3) can be pressed to start spinning and accelerating the spinning bodies (1); when the spin speed is high enough, grab the yoyo string and then release the yoyo; the player can then have sufficient time to perform various yoyo tricks. Accordingly, even a short player can play the yoyo. Further, the yoyo can once again be accelerated when its spin speed is too slow. When the side shaft sleeves (3) are not grabbed, the electrical acceleration mechanism stops operating while the yoyo will still continue to spin due to inertia, thereby providing much fun in playing the yoyo. The yoyo has a wide range of utility satisfying the playing needs of kids and children.
