Abstract: Disclosed are methods of modeling stimulation treatments, such as designing matrix treatments for subterranean formations penetrated by a wellbore, to enhance hydrocarbon recovery. The modeling methods describe the growth rate and the structure of the dissolution pattern formed due to the injection of a treatment fluid in a porous medium, based on calculating the length scales for dominant transport mechanism(s) and reaction mechanism(s) in the direction of flow l X and the direction transverse to flow l T. Methods of the invention may further include introducing a treatment fluid into the formation, and treating the formation.

Abstract: An apparatus for application of a liquid manure to soil, possessing a frame which is adapted when towed over soil to apply such to the soil. A supply conduit, having a distal end and a proximal end is provided. The distal end thereof is adapted to be releasibly coupled and in fluid communication with a flexible supply hose which supplies the liquid-solid solution, such as liquid manure, to the distal end of the conduit. The proximal end of the conduit is in fluid communication with a manifold which thereafter via a plurality of supply tubes supplies such liquid/liquid solid dispersion to the soil. An intermediate portion of the supply conduit is flexible. A boom member at its distal end supports a distal end of the supply conduit. A proximal end of the boom member is pivotably coupled to the frame to allow pivotal movement of the distal end of the boom member in at least a horizontal plane. The pivotal coupling in a preferred embodiment further permits limited vertical movement of the distal end of the boom member to better allow direct transmittal of tensile pulling forces on the flexible supply hose to reduce the incidence of kinking of such supply hose.

Title: System and method for preserving multicast data forwarding during control failures in a router
Inventor: WINDISCH KURT J
IPC: H04J3/26
Filed: 2005-07-20
Granted: 2011-05-24
Abstract: A multicast non-stop forwarding (NSF) router architecture enhances high availability of a multicast router (400) in a computer network. The router architecture further preserves multicast data forwarding through a data plane (470) during NSF recovery of one or more failures in a control plane (410) of the router(400). Various multicast components of the router (400) cooperate to provide a checkpointing and recovery technique of the multicast NSF  architecture that enables efficient restart and recovery of the control plane failures without loss of data connectivity. In addition, a technique prevents multiple multicast forwarders from forwarding multicast packets for a route over a link in a computer network during NSF recovery of one or more failures in a control plane (410) of a multicast router (400).
