Abstract: Implementations of systems for tracking and trading assets may include an order book module configured to generate an order book, an exchange module configured to retrieve holdings information associated with a user, a tracking module configured to calculate a delta of a rate of exchange between two assets recorded within the order book, a block module configured to generate one or more blocks, each block representative of an asset of the first plurality of assets, and a trade module configured to transmit a trade request to the one of the brokerage, the exchange, or the brokerage and the exchange. The trade module may be configured to receive, from a user, a single trade request between a first asset and a second asset. The trade module may be configured to calculate a plurality of trade routes between the first asset and the second asset through one or more “medium” assets.

Abstract: A technique that is usable with a well includes running an isolation device into the well and using the isolation device to form a seal to create a first region of the well isolating the surface of the well from a second higher pressure region of the well. The technique includes running an assembly into the first region and engaging the isolation device with the assembly to remove the seal. After removal of the seal, the isolation device and assembly are run together further into the well.
