    摘要: Well servicing methods and systems are described, in one embodiment comprising a pressure containment housing fluidly connected directly to a wellhead of a wellbore, and a reel positioned inside the housing on which is spooled a communication line. One method comprises introducing the communication line into the pressurized wellbore without a well control stack, the communication line being introduced and driven into the wellbore by controlling a reel, the reel being internal to a pressurized housing removably connected directly to a wellhead of the wellbore. Fluid flow may move the communication line to a desired location in the wellbore. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It may not be used to interpret or limit the scope or meaning of the claims.

    摘要: A method and apparatus for producing gas from a hydrate formation includes the use of at least one wellbore which penetrates the hydrate formation and further extends into an aquifer below the hydrate formation. The aquifer provides relatively warm water which may be produced up and into the hydrate formation thereby causing the release of gas from the hydrate. Suitable flow control and monitoring equipment may be included to control the flow of water produced from the aquifer and gas produced from the hydrate formation.
