Abstract: A method for performing simultaneous operations at a wellsite comprising two or more adjacent wellheads, each respectively connected to a well, may include the following steps: providing a fluid supply via upstream equipment to an intermediate supply point; fluidly connecting the intermediate supply point to a single wellhead, the fluidly connecting comprising connecting a first end of a flexible pipe to the intermediate supply point and a second end of the flexible pipe to a first wellhead; performing a wellbore operation on a first well using the fluid supply from the upstream equipment supplied to the first wellhead; disconnecting the second end of the flexible pipe from the first wellhead; and connecting the second end of the flexible pipe to a second wellhead.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless stations (STAs) may be within the coverage areas of several of access points (APs). In such cases, STAs may detect some set of candidate APs for possible connection, and the STAs may perform some selection procedure to select an AP for connection. For example, a STA may score or rank available APs (e.g., APs within the set of candidate APs), and the STA may sort the candidate APs into different bins (e.g., categories) based on their respective scores (e.g., based on each AP's candidate score). Each bin may thus include one or more APs associated with some scoring range. A STA may then randomly (e.g., or pseudo-randomly) select an AP from the bin associated with a highest range of candidate scores, and the STA may connect to the selected AP.

Abstract: Disclosed herein is a filter apparatus comprising a fluid inlet for a fluid to be filtered in the apparatus; a first fluid outlet for fluid that has been filtered; and one or more barrier filters arranged between the fluid inlet and the first fluid outlet for filtering material from the fluid. In use, the fluid to be filtered is directed from the fluid inlet so as to promote a continuous erosion of material built up on the barrier filter(s). Also disclosed is a method of filtering particles from a particle laden fluid.

Abstract: A heat transfer apparatus and method comprises first and second heat transfer units. A heat exchanger has a first portion thereof arranged between the first and second units, and a second portion that is thermally connected to the first portion and not arranged between the first and second units. Each heat transfer unit comprises one or more modules, and each module comprises a chamber having a first part which contains a first gas adsorbent material and a second part which contains a second gas adsorbent material. These parts are connected so as to allow gaseous communication therebetween whilst being relatively thermally isolated from each other.

Abstract: A method for vaporizing and heating a cryogenic fluid such as a liquefied natural gas, to a desired temperature in the ambient temperature range. The method comprises using an intermediate heat exchange fluid such as propane to heat the liquefied natural gas and to utilize the cold potential of the liquefied natural gas to produce power. The heat exchange fluid is heated by a heat source, such as warm or hot water available from an industrial process. The heat exchange fluid is pressurized and heated to form a heat exchange vapor. The heat exchange vapor is split into multiple streams that exchange heat with the cryogenic fluid in series fashion so that the cryogenic fluid is vaporized and heated to the desired temperature in stages using a common heat exchange fluid and heat source.

Abstract: A heat transfer apparatus (20) and method comprises first (R2/D2) and second (R1/D1) heat transfer units. A heat exchanger (30) has a first portion (32) thereof arranged between the first and second units, and a second portion (34) that is thermally connected to the first portion and not arranged between the first and second units. Each heat transfer unit comprises one or more modules (10), and each module comprises a chamber having a first part (12) which contains a first gas adsorbent material and a second part (14) which contains a second gas adsorbent material. These parts are connected (16) so as to allow gaseous communication therebetween whilst being relatively thermally isolated from each other.

Abstract: A method, apparatus and system for transferring heat is disclosed using a first gas adsorbent material, and a second gas adsorbent material that is relatively thermally isolated from but in continuous gas communication with the first material. In a first step the first material is heated so as to desorb a gas adsorbed onto the first material whereby the gas passes to and is adsorbed onto the second material. In a second step the first material is cooled in a manner so that the gas is desorbed from the second material and passes therefrom to be re-adsorbed onto the first adsorbent material. When the gas is desorbed from the second material, the second material is cooled thereby. In this way a hot gas stream can be used to cool another gas stream.

Abstract: A process and apparatus is provided for reducing the heating value of imported LNG by removing natural gas liquid products while condensing boil-off gas. The LNG is pumped from a storage container and is then heated by cross exchange to a dew point temperature. A portion of this heated LNG is sent out to be vaporized while the remaining portion is further heated by cross exchange with demethanizer overhead vapors and is then sent as feed to the demethanizer. NGL is recovered at the bottom of the demethanizer, and the overhead vapors are mixed with boil off gas coming from the LNG storage container. These mixed vapors are condensed by cross exchanging with the LNG feed portion and then pumped to pipeline pressure and sent to the gas pipeline through the vaporizers.
