    Abstract: An apparatus and methods for pumping a fluid mixture from a wellbore location to a selected location is disclosed. The apparatus, in one embodiment, includes a container configured to be placed in the wellbore, wherein the container is configured to mix therein a fluid received from a first source and an additive received from a second source, and a pump unit coupled to the container and configured to pump the mixed fluid from the container to the selected location. The method in one embodiment includes: supplying a fluid from a first source to a container placed in a wellbore; supplying an additive from a second source to the container; allowing the fluid and the additive to mix in the container to form a mixed fluid; and pumping the mixed fluid from the container to the selected location.

    Abstract: A system of transferring information comprises transmitting a data signal and a known signal from a first location over a signal channel ChB having a first noise component NIB. A second noise component NIAis measured in a noise channel ChA adjacent the signal channel. The data signal, the known signal, and the first noise component are received at a second location. The first noise component is estimated based on the second noise component and may be estimated based on a combination of the second noise component and a third noise component NICtaken from a second adjacent channel ChC. The estimated noise component is combined with the received data signal and the received known signal to generate noise-cancelled received data and received known signals. The noise-cancelled received known signal is processed to obtain an estimate of the channel transfer function. The estimated channel transfer function is combined with the noise-cancelled received data signal to reconstruct the transmitted data signal.

    Abstract: Composite tubulars that have not been polymerized and are thus flexible enough to be coiled are delivered into a wellbore and expanded. The expansion occurs from an external catalist such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.

    Abstract: A system and methods of transmitting information between a first location and a second location comprise transmitting a data signal and a known signal from one of the first location and the second location over a signal channel having a first noise component. A second noise component is measured in a noise channel adjacent the signal channel. The data signal, the known signal, and the first noise component are received at the other location. The first noise component is estimated based on the second noise component. The estimated noise component is combined with the received data signal and the received known signal to generate noise-cancelled received data and received known signals. The noise-cancelled received known signal is processed to obtain an estimate of the channel transfer function. The estimated channel transfer function is combined with the noise-cancelled received data signal to reconstruct the transmitted data signal.
