Patent number: 7249633Abstract: A bottom hole assembly for use with fracturing or fracing a wellbore using coiled tubing is described having a first packing element and a second packing element on a mandrel. The bottom hole assembly may be run into the wellbore such that the packing elements straddle the zone to be fraced. Also described is a timing mechanism to prevent the closing of dump ports before the bottom hole assembly may be flushed of the sand. A release tool is described that allows an operator to apply combination of force for a given amount of time to the coiled tubing to dislodge a bottom hole assembly without completely releasing the bottom hole assembly. Also disclosed is a collar locator capable of being utilized in a fracing process. Methods of using the above-described components are also disclosed.Type: GrantFiled: June 15, 2004Date of Patent: July 31, 2007Assignee: BJ Services CompanyInventors: John Edward Ravensbergen, Andre Naumann, Lubos Vacik, Mitch Lambert, Graham Wilde

Patent number: 5417538Abstract: An apparatus is provided for scooping up articles typically golf balls, from the ground comprising a rotary scoop 16 which can rotate about an axis 18 extending parallel to the ground 14. The scoop 16 is provided with three elongate elements uniformly spaced in the radial direction about and extending parallel to the axis of rotation 18. A curved plate 32 is located behind the scoop 16 in the direction of travel D of the apparatus 10. The plate 32 has a lower edge 34 extending parallel to the ground 14 at a height to prevent the passage of the golf ball to fall between the edge 34 and the ground 14. A cylindrical receptacle 38 is located between the elongate elements 20 and has its longitudinal axis coincident with the axis of rotation 18. An opening 40 is formed along the length of the receptacle 38 near an upper edge 42 of the place 32. A golf ball 12 scooped by the scoop 16 is guided by plate 32 so as to fall by the action of gravity through opening 40 into the receptacle 48.Type: GrantFiled: February 8, 1994Date of Patent: May 23, 1995Inventor: Graham Wilde
