Filed: December 10, Date of Patent: July 26, Assignee: Allamon Interests. Allamon, Jack E. Downhole surge reduction method and apparatus.

In accordance with the present invention, a surge pressure reduction tool includes a diverter device having a housing with a set of flow holes formed therein and a sliding sleeve residing within the housing having a set of flow ports formed therein. This shifting or indexing is accomplished using an indexing mechanism. Filed: July 1, Date of Patent: August 3, Miller, Andrew M. Abstract: A drop ball catcher apparatus for use with downhole tools in oil well drilling and installation operations is disclosed.

In accordance with the present invention, a drop ball catcher apparatus is used to receive and stow a drop ball ejected from a ball-actuated downhole tool. Moreover, the drop ball catcher apparatus may also be used as the primary activation device for a downhole tool such as a liner hanger or a circulation device.

Publication date: June 10, Float collar. Apparatus of the present invention is fabricated using plastic flapper valves and valve-actuating sleeve components in contrast to prior art float collar components which are fabricated almost entirely of hard metals. Particularly, the plastic may be nylon, phenolic, or a phenolic-nylon laminate. The use of plastic components in the float collar apparatus of the present invention provides a substantial reduction in time and resources expended during drilling out of the float collar once cementing operations are completed.

The UltraSeal is industry-leading with the highest bump and back pressure rating for large bore type auto-fill float equipment at 7, psi. It is fully PDC-drillable. The UltraSeal will maximize cement column height for increased well safety and regulatory compliance. The large ID through the valves and ball seat will not only allow for maximized running speeds, it also reduces surge pressures, which will decrease costly mud loss and improve well control.

The increased running speed can result in a significant amount of rig time savings. With its tapered landing surface, it is compatible with most subsurface release plug sets. Comments on this page are closed. Facebook Twitter Contact Do you have any tips to us. Scandinavian Oil-Gas Online.

ISSN X. The UltraSeal utilises the latest generation composites to achieve performance that was once impossible. The engineering improvements are reflected in the field data. The Dual Wiper Plug substantially increases cement slurry integrity by providing a fluid barrier on each end of the cement slurry while the cement is pumped through the casing. The Dual Wiper Plug incorporates the use of two drill pipe darts which provide a protective barrier for the cement in the workstring while wiping the inside of the drill pipe, and then launching the appropriate casing wiper plug in the Dual Wiper Plug system.

The components of the Dual Wiper Plug are constructed mostly of composite material, which enhance plug reliability and drill-out.
