A production sting has a premium thread preferably VAM or similar for threading into a packer extension without the need for a seal stack to engage a seal bore in the extension. The seal bore use becomes optional and a metal to metal seal is provided by the premium thread whether the string is in compression or tension. Another adjacent left hand square thread is provided in the packer extension to land accessory tools or for removal of the packer after the packer is released in a variety of known ways. Either the premium thread or the left hand thread can be in the uphole position on the packer extension.

A velocity string system includes a lock mandrel. A seal bore assembly attached to the lock mandrel runnable in a production string; and a velocity string sealable in the seal mandrel and separately runnable in the production string. A method for installing a velocity string system in a production string.

System and method to install velocity string

A selectively two directional check valve is located on a string with a packer and is either held open for running in so that the string can fill and doesn't become buoyant or includes a closable ported sub to allow string filling for running in that can then be closed. Pressure is applied from the surface to drive an object down to a seat so that a packer can be set. Further pressure increase shifts the object and the seat and locks the seat in the shifted position. A spring return force pushes the object to an upper seat to prevent uphole flow. Flow in the downhole direction is possible by overcoming the spring bias to move the object off the upper seat while preventing the object from moving down far enough to engage the shifted lower seat. Flow downhole just goes around the object.

A plug for a seal bore in a packer mandrel has a shiftable annular member that can selectively open bypass ports to facilitate latching and then be shifted as part of a release from the plug by a running tool to close the bypass passage that go around a frangible barrier that will later be broken by impact force. The annular member has minimal structure internally to allow attachment of the running tool. The annular member drillout proceeds quickly with minimal cuttings and the frangible member is broken by impact. On an assembly with multiple packers getting plugs a trip is saved as a plug is delivered into a lower packer with a string supporting the packer above. The plug is set in the lower packer allowing release of the running string for subsequent placement and setting of the next packer in the same trip.

A flow control valve including, a tubular housing having a valve port, a piston disposed in the tubular housing having an orifice, the piston being slidable in the tubular housing to align the orifice with the valve port, a combustion portion at least partially defined by the tubular housing and the piston, and a propellant disposed in the combustion portion and method.
