摘要： A method of operating a filtration unit of a filtration system includes
feeding, during filtration, feed water containing suspended particulate material to an inside of each of a plurality of hollow fibres through a first inlet and a second inlet of each hollow fibre while simultaneously removing a filtrate from an outside of each of the hollow fibres through an outlet of a filtration elements. In addition, the method includes feeding,
during back-washing, back-wash water to the outside of the hollow fibres through the outlet of the filtration element. Further the method includes discharging, in a first back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from one end thereof. Still further, the method includes discharging, in a second back-wash cycle, back-wash water containing entrained particulate material from the inside of the hollow fibres from the other end thereof.-

摘要： In some examples, the disclosure provides a method for determining a drift in clock data that is provided by a clock of a seismic sensor. The sensor is exposed to an ambient temperature that varies over time. The method includes obtaining temperature data associated with the ambient temperature as a function of time. The method also includes obtaining the clock data. The method also includes obtaining timestamp data provided by a global navigation satellite system. The method also includes determining drift data which minimizes a difference of a temporal drift in the clock data, based on the timestamp data and the temperature data. The method also includes outputting corrective data based on the determined drift data.

摘要： A seismic sensor for a seismic survey includes an outer housing having a central axis, a first end, and a second end opposite the first end. The first end comprises a portion made of a clear material configured to transmit light having a frequency in the visible or infrared range of the electromagnetic spectrum. In addition, the seismic sensor includes a proof mass moveably disposed in the outer housing. The proof mass includes a power source. Further, the seismic sensor includes a sensor element disposed in the outer housing and configured to detect the movement of the outer housing relative to the proof mass. Still further, the seismic sensor includes electronic circuitry coupled to the sensor element and the power source. The seismic sensor also includes a light guide assembly having a first end adjacent the clear portion of the first end of the outer housing and a second end adjacent the electronic circuitry. The light guide assembly is configured to transmit light in an axial direction between the first end of the light guide assembly the clear section and to transmit light in a non-axial direction between the second end of the light guide assembly and the electronic circuitry.

摘要： A process for reducing the permeability to water of a thief zone of a porous and permeable subterranean petroleum reservoir includes injecting a composition comprising a dispersion of betainised crosslinked polymeric microparticles in an aqueous fluid down a well and into a thief zone. The betainised crosslinked polymeric microparticles have a transition temperature that is at or below the maximum temperature encountered in the thief zone and greater than the maximum temperature encountered in the well. The betainised crosslinked polymeric microparticles are solvated by water, expand in size and optionally aggregate in the thief zone when they encounter a temperature greater than the transition temperature so as to reduce the permeability of the thief zone to water.
