    Abstract: An oilfield material reservoir is disclosed. The oilfield material reservoir has a body, the body having an upper end, a lower end, a sidewall extending between the upper and lower ends, the sidewall defining a recess within the body, an opening defined by the upper end, and a first orifice defined by the lower end. The oilfield material reservoir is also provided with a metering gate connected to the body at the lower end. The metering gate has a base having a second orifice aligned with the first orifice, and a knife gate connected to the base. The second orifice has a substantially trapezoidal shape. The knife gate is configured to slidably cover the second orifice. A method is also disclosed for controlling a discharge rate of oilfield material within the oilfield material reservoir by adjusting a metering open area of the second orifice according to mathematical modeling equations.

    Abstract: A method, apparatus, and program product model stress characteristics of a subsurface formation based at least in part on acoustic data and image data associated with the subsurface formation. The acoustic data is analyzed to determine acoustic based stress values, and the image data is analyzed to determine image based stress values. The acoustic based stress values and the image based stress values are integrated to generate an integrated stress profile that includes one or more modeled stress characteristics of the subsurface volume.

    Abstract: A petrophysically regularized time domain nuclear magnetic resonance (NMR) inversion includes using an NMR tool to acquire NMR data and inverting the acquired NMR data in a time domain using petrophysical constraints. The inverted NMR data is analyzed. The petrophysical constraints may be identified by: determining a number of porobodons to seek, defining a plurality of zones in which only a subset of porobodon sets is present, and stacking all NMR echoes in each zone satisfying discriminators. The number of porobodons to seek may be based on knowledge of core samples, logs, and NMR sensitivity. The discriminator logs may be logs sensitive to porosity partitioning. A computing system having a processor, a memory, and a program stored in memory may be configured to perform the method. The system may be conveyed downhole on a wireline, a while-drilling drill string, a coiled tubing, a slickline, or a wired drill pipe.

    Abstract translation: 岩石物理正则化的时域核磁共振（NMR）反演包括使用NMR工具获得NMR数据并且使用岩石物理学约束在时域反转获取的NMR数据。 分析反相NMR数据。 岩石物理学约束可以通过以下方式来确定：确定多个孔体以寻找多个区域，其中仅存在孔体组的子集，并且在满足鉴别器的每个区域中堆叠所有NMR回波。 要寻求的孔洞数量可能是基于核心样本，原木和核磁共振敏感性的知识。 鉴别器日志可能是对孔隙度划分敏感的日志。 具有处理器，存储器和存储在存储器中的程序的计算系统可以被配置为执行该方法。 该系统可以在电缆，同时钻井钻柱，盘管，钢丝绳或有线钻杆的井下传送。

    Abstract: Disclosed is a tube, a swell packer and two plates coupled to an outer surface of the tube and positioned at an end of the swell packer. Each of the plates has multiple slots extending inwardly from an outer edge of the plate, the regions between slots define petals. At least one of the slots of one of the plates overlaps with at least one of the petals of the second of the plates. Two more plates are coupled to the outer surface of the tube and positioned at a second end of the packer. Each of the two other plates has multiple slots extending inwardly from an outer edge of the plate. The regions between slots define petals. At least one of the slots of one of the two other plates overlaps with at least one of the petals of the second of the two other plates.
