Patent number: 7971650Abstract: A method of pumping wellbore fluid, comprising the steps of: installing an electric submersible pump in a wellbore; and operating the pump at more than 4,500 rpm to pump the wellbore fluid. Pumping in this manner provides a number of advantages in use in that the required high-speed motor and pump is shorter for a given power than existing arrangements, and provides increased reliability due to reduced complexity. A much shorter motor/pump combination also allows such equipment to be used in deviated boreholes with a reduction in damage due to mishandling and bending, as well as facilitating assembly and testing in the manufacturer's plant.Type: GrantFiled: June 21, 2004Date of Patent: July 5, 2011Assignee: Oilfield Equipment Development Center LimitedInventors: Michael Andrew Yuratich, Alan Thomas Fraser

Patent number: 7726997Abstract: An electrical connector assembly for a cable having a plurality of insulated conductors comprises a body having a respective recess for receiving a terminating pin each of the conductors. A respective spigot sealingly engages within each of the recesses and has a passage for receiving an associated one of the terminating pins. Furthermore a seal is associated with each of the spigots for sealing the spigot relative to the associated terminating pin. The provision of a separate spigot for each of the conductors and for sealing engagement within a respective recess in the body enables the spigots to be sealingly fitted to the conductors prior to each spigot being introduced into its recess and sealingly engaged therein. This provides improved insulation of the conductor and increased creepage distance between the mating electrical parts and the outer surface of the housing of the assembly.Type: GrantFiled: August 31, 2007Date of Patent: June 1, 2010Assignee: Oilfield Equpiment Development Center LimitedInventors: Steven Charles Kennedy, Michael Andrew Yuratich, Trevor Alan Kopecky, Alan Thomas Fraser

Patent number: 6868901Abstract: A tubular cutting tool includes two or more sets of electrically actuated retractable anchoring legs mounted at longitudinally spaced apart locations and an electrically driven rotary cutting head with a retractable cutting blade. The anchoring legs can be arranged such that they are capable of compensating for variations in the internal radii of the tubular to be cut, thereby ensuring that the cutting tool is clamped rigidly in position.Type: GrantFiled: March 12, 2002Date of Patent: March 22, 2005Assignee: Sondex LimitedInventors: Guy Harvey Mason, William Peter Stuart-Bruges, Thomas Lempriere Searight, Philip Anton Strong, Timothy George Boxell, Michael Andrew Yuratich, Alan Thomas Fraser
