    • The water includes a tank 10 which includes dual cold water inlets 21a, 21b. One or other of the cold water inlets 21a, 21b is in use connected to a cold water supply line. The cold water inlets 21a, 21b extend through inlet pipes 21c, 21d within the tank 10 and join at a cold water junction 22. Extending upwardly for cold water is a tempering tube or pipe 31, 31a, 31b that extends within the tank to the upper region of the tank 10 where the cold water can mix with hot water being drawn from the tank and passing through one of a pair of hot water outlets 26a, 26b. Either of the water outlets 26a, 26b in use is connected to a hot water delivery line for supply of the tempered water.

    • A method and system for estimating reservoir pressure in a hydrocarbon reservoir from downhole pressure measurements of producing wells is disclosed. Pressure measurements are obtained from wells in the production field over time, and communicated to a server that applies the pressure measurements for a well to a model of that well. The server operates the model using the pressure measurements to determine an operating mode of the well, such as producing or shut-in. Upon detection of a change in operating mode indicative of an abrupt change in flow at the well, such as corresponding to a shut-in event, additional downhole pressure measurement data is acquired until a steady-state condition is reached. The pressure measurements are used to determine a reservoir pressure, which is transmitted to a responsible reservoir engineer or other user. Modification of the determined reservoir pressure value by the user can be received, and the stored reservoir pressure and well model are updated accordingly.
    • 公开了一种用于从生产井的井下压力测量值估计烃储层中的储层压力的方法和系统。 压力测量是从生产领域的井中随时间获得的,并传达给将井的压力测量值应用于井的模型的服务器。 服务器使用压力测量来操作模型,以确定井的操作模式,例如生产或关闭。 在检测到表示井的流量突然变化的操作模式的变化(例如对应于关闭事件)时,获取额外的井下压力测量数据,直到达到稳态条件。 压力测量用于确定储层压力,其被传送到负责的储层工程师或其他用户。 可以接收用户对所确定的储层压力值的修改,并相应地更新存储的储层压力和井模型。

    • The water heater includes a burner and a water tank. Combustion products flow upwardly around the tank through a combustion products path where heat transfer to water in the tank occurs, the path being defined between the outer wall the tank and a surrounding heat exchanger wall. The combustion products pass through outlet at the upper end of wall, and enter the flue which includes a down flow passage and then pass out through discharge outlet. The down flow passage is defined between a flue outer wall and a thermally conductive partition defining the inner wall of the passage. The partition is adjacent a heated zone of the water heater where stored heat of the water heater is available during quiescent or standby periods when the burner is not operating. The partition between the heated zone and the down flow passage provides a heat transfer path so that heat in the heated zone can transfer through the partition to gases in the down flow passage. This will assist or promote the functioning of the down flow passage as a heat trap during quiescent or standby periods when the burner is not operating.
    • 热水器包括燃烧器和水箱。 燃烧产物通过燃烧产物路径向上流过罐体,燃烧产物路径中发生向罐中的水的传热,路径被限定在罐的外壁和周围的热交换器壁之间。 燃烧产物通过壁上端的出口,进入包括下流道的烟道,然后通过出口排出。 下流通道限定在烟道外壁和限定通道内壁的导热隔板之间。 分隔件与热水器的加热区相邻,在燃烧器不工作的静止或待机期间,热水器的存储热量可用。 加热区域和下游通道之间的隔板提供传热路径,使得加热区域中的热量可以通过隔板传递到下部流动通道中的气体。 这将在燃烧器不工作时在静止或待机期间帮助或促进下流道作为热阱的功能。
