Patent number: 9359871Abstract: A basket is attached below a retrievable bridge plug used during the pressure testing of a well to verify integrity prior to fracturing operations. After the pressure integrity test above the plug, the plug is released and retrieved and a series of balls of increasing diameter are dropped on increasingly larger ball seats to allow shifting sleeves to an open position from the heel of the well toward the surface to sequentially frac in that direction. If any segments of the sealing element break off they are captured and removed in the basket that has flow through opening small enough to retain the debris and allow flow through the basket during removal. The basket is slotted for through fluid flow and can have a breakaway for the support rod if the basket sticks when the plug is removed.Type: GrantFiled: March 5, 2012Date of Patent: June 7, 2016Assignee: Baker Hughes IncorporatedInventors: Matthew L. White, David A. Dolyniuk, Steve Rosenblatt

Patent number: 9004185Abstract: A plug drop tool, including a body defining a chamber, a plug initially housed in the chamber and a member disposed with the body. The member is actuatable for selectively enabling communication between the chamber and an annulus at least partially defined by the body. The plug is movable into the annulus when the communication is enabled.Type: GrantFiled: January 5, 2012Date of Patent: April 14, 2015Assignee: Baker Hughes IncorporatedInventors: Paul Madero, Clint E. Mickey, David A. Dolyniuk

Publication number: 20070272414Abstract: The riser assembly is plugged adjacent its bottom end either as it is made up or after full makeup or anywhere in between. A heavy fluid is either added to the riser string as it is made up or delivered into the string after makeup to displace seawater or other fluids that may have been in the riser as it is assembled. The floating rig can be secured over the subsea well head and the riser now full of heavy fluid is less prone to be displaced by wave action and preferably simply dangles straight down so that the connection to the subsea wellhead can be simply accomplished. The effect of wave action is minimized or eliminated when deciding placement of the floating rig with respect to the wellhead. Repositioning of the rig takes less effort and is needed less frequently.Type: ApplicationFiled: May 26, 2006Publication date: November 29, 2007Inventors: Larry T. Palmer, David Dolyniuk

Publication number: 20070256867Abstract: A mill assembly having a milling head which is releasable from the mill body, such as by shifting a ball clutch mechanism. The ball clutch mechanism can be shifted by dropping a pumpable plug through the work string to block fluid flow through the releasable milling head, or by increasing fluid flow through a constriction in the releasable milling head to increase the back pressure above the milling head. A check valve in the milling head can prevent uphole flow through the work string in the event of a pressure excursion. A fishing neck can be attached to the milling head.Type: ApplicationFiled: June 29, 2007Publication date: November 8, 2007Applicant: Baker Hughes IncorporatedInventors: Joseph DeGeare, Mark Plante, David Dolyniuk, John Davis

Publication number: 20070221414Abstract: A mill assembly having a milling head which is releasable from the mill body, such as by shearing a shear pin. The release mechanism can be released by dropping a pumpable plug through the work string to block fluid flow through the releasable milling head, or by increasing fluid flow through a constriction in the releasable milling head to increase the back pressure above the milling head. A check valve in the milling head can prevent uphole flow through the work string in the event of a pressure excursion. A fishing neck can be attached to the milling head.Type: ApplicationFiled: May 21, 2007Publication date: September 27, 2007Applicant: Baker Hughes IncorporatedInventors: Joseph DeGeare, Mark Plante, David Dolyniuk, John Davis

Publication number: 20050230108Abstract: A liner hanger test packer assembly includes an axially translated liner top dressing mill having a calibrated shear mechanism for securing the mill at a first, top dressing position. Tool string load on the mill bearing upon the liner top in excess of the calibrated shear mechanism allows the mill to shift to a second axial position where abutment edges around the Mill base engage a tripping mechanism to drive slips against the casing wall above the liner hanger. The tripping mechanism also expands the packer seal against the casing I.D. above the liner hanger. No additional load may be imposed on the liner hanger after the anchor slips have engaged.Type: ApplicationFiled: April 14, 2005Publication date: October 20, 2005Applicant: Baker Hughes IncorporatedInventors: Gordon Mackenzie, Mark Plante, Richard White, David Dolyniuk

Patent number: 6915858Abstract: A latching assembly for a lower collar on an inflatable is provided. After deflation, the lower collar is engaged to the mandrel so that the deflated inflatable can be advanced with other connected downhole equipment, such as screens to be expanded, in a location further downhole without swabbing.Type: GrantFiled: October 24, 2002Date of Patent: July 12, 2005Assignee: Baker Hughes IncorporatedInventors: David A. Dolyniuk, George S. Arnold
