An internet router is implemented as a network fabric of fabric routers and links. The internet router receives data packets from trunk lines or other internet links and analyzes header information in the data packets to route the data packets to output internet links. The line interface also analyzes the header to define a fabric path through the router fabric. The internet packets are broken into flits which are transferred through the router according to a wormhole routing protocol. Flits are stored in fabric routers at storage locations assigned to virtual channels corresponding to destination internet links. The virtual channels and links within the fabric define virtual networks in which congestion in one virtual network is substantially nonblocking to data flow through other virtual networks. Arbitration is performed at each fabric router to assign packets to virtual channels and to assign virtual channels to output fabric links. A virtual channel is enabled for possible assignment to an output fabric link upon receipt of an indication that an input buffer is available at the next fabric router of the path.

A method for optimizing the rate at which a given acid should be injected into a carbonate-containing rock formation during an acid injection process. The first step of the method calculates the Damkohler numbers for regimes in which kinematic force, diffusion rate and reaction rate control. The Damkohler numbers are then used to calculate the rate of growth of wormholes as a function of flux, taking into account compact dissolution, wormholing, and uniform dissolution. The calculated function is used to calculate an optimum flux for the formation. The optimum flux is then used to calculate an optimum injection rate at a given point in the acid injection process.

A scalable low-latency switch extends the functionality of a multiple level minimum logic interconnect structure for usage in computers of all types, networks and communication systems. The multiple level minimum logic interconnect structure employs a data flow technique based on timing and positioning of messages moving through the structure. The scalable low-latency switch is distributed throughout multiple nodes in the structure so that a supervisory controller providing a global control function and complex logic structures are avoided while the interconnect structure operates as a "deflection" or "hot potato" system in which processing and storage overhead at each node is reduced. The interconnect structure using the scalable low-latency switch employs a method of achieving wormhole routing through an integrated circuit chip by a novel procedure for inserting messages into the chip. Rather than simultaneously inserting a message into each unblocked node on the outer cylinder at every angle, messages are inserted simultaneously into two columns A and B only if an entire message fits between A and B. Messages are inserted into column 0 at time 0. Messages are inserted into column 1 at time t0+tC, where time tCis the time for a first bit of a message to move from column 0 to column 1 on the top level. Messages are inserted into column 2 at time t0+2tC, and so forth. The strategy prevents the first bit of one message from colliding with an interior bit of another message already in the switch. Contention between entire messages is addressed by resolving the contention between the first bit only so that messages wormhole through many cells.

When data moves down a level, an additional bit of the target output is fixed so data exiting from the bottom of the structure arrives at the proper target output port.

Another step is used to inject a gel precursor within the zone, which upon setting, produces a gel plug that also reduces pressure communication and driving fluid flow through the halo region of the zone.
