Abstract: The density of at least one fluid in a pipe is determined using a pair of effective sound speeds a1eff and a2eff of the fluid/pipe system. The pair of effective sound speed measurements is taken at two sensing regions along the pipe wherein each of the sensing regions has a different cross sectional area compliance. The pair of effective sound speeds a1eff and a2eff is provided to signal processing logic (60), which determines the density of the fluid flowing in the pipe. The effective sound speeds a1eff and a2eff may be provided by a pair of sound speed meters positioned at the sensing regions wherein the sound speed meters utilize a spatial array of acoustic pressure sensors placed at predetermined axial locations along the pipe. The acoustic pressure sensors measure one-dimensional planar acoustic waves that are lower in frequency (and longer wavelength) signals than those used for ultrasonic flow meters, and thus is more tolerant to inhomogeneities in the flow. In addition, no external acoustic source is required and the meters may operate using passive listening.

Abstract translation: 使用流体/管道系统的一对有效声速a1eff和a2eff来确定管道中的至少一种流体的密度。 在沿着管的两个感测区域处获取一对有效的声速测量，其中每个感测区域具有不同的横截面积顺应性。 一对有效声速a1eff和a2eff被提供给信号处理逻辑（60），其确定在管道中流动的流体的密度。 有效声速a1eff和a2eff可以由位于感测区域处的一对声速计提供，其中声速计利用放置在沿着管道的预定轴向位置处的声压传感器的空间阵列。 声压传感器测量频率（和较长波长）信号比用于超声波流量计的一维平面声波，因此更容忍流动中的不均匀性。 此外，不需要外部声源，并且仪表可以使用被动聆听操作。

Abstract: Apparatus and methods for measuring cross sectional area and flaws in a continuous sucker rod string (20) as the string is conveyed within a borehole (32). These measured parameters are useful in monitoring the physical integrity of the sucker rod string. A magnet (44) is used to saturate an increment (48) of continuous sucker rod, and a coil (45) is used to measure induced flux. Cross sectional area of the rod increment is computed from the flux measurement. One or more Hall effect transducers (42) are used to measure leakage from the increment as a function of distance along the increment. This measurement is used to detect and quantify the type of flaw within the rod increment being investigated. The process is repeated as the sucker rod string is conveyed into or out of the borehole.

Abstract: An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion (160) of a casing or housing (110). In one aspect of the invention, a sleeve (150) is disposed in the housing to isolate an annular area (155) defined by the outer surface sleeve and the wall of the enlarged inner diameter portion. The sleeve prevents unwanted materials from being disposed in the annular area. The sleeve can later be expanded into the enlarged inner diameter portion, removed from the wellbore or destroyed. In another aspect of the invention, the sleeve is provided and disposed to cover the enlarged inner diameter portion. By covering the enlarged inner diameter portion, unwanted material is prevented from accumulating at said portion and from interfering with the expansion of the next casing into said portion to form a monobore. The sleeve can be made from materials that are dissolvable, elastically deformable, or retrievable.

Abstract: A high strength sucker rod coupling for use with high strength sucker rods, and methods for fabricating the coupling. The coupling (10) is fabricated from a hardened, hollow cylindrical coupling blank (12). An outer surface (14) of the coupling blank is coated with spray metal alloy, and the coated blank is heated to fuse the spray metal to the outer surface thereby forming a wear layer (16). This coating decrease brittleness of the wear layer, and limits cracking and subsequent stress riser effects on fatigue performance. The coupling blank is austenitized and liquid quenched to a specified hardness range. Fully cold formed threads (18) are formed on an inner surface of the coupling blank.
