Title: Pressure filtration using a diaphragm
Inventor: SULLIVAN MICHAEL SHANE
IPC: B01D29/15
Filed: 2001-02-16
Abstract: A pressure filtration apparatus comprises a filter medium 21, a diaphragm (Fig 1,13) movable under fluid pressure between an operative (Fig 2, 13) and an inoperative position, and fluid pressure supply means that urges the diaphragm toward the operative position when feed, such as a slurry, is supplied to the apparatus. Preferably the fluid pressure supply means is provided with pressure release means to reduce pressure exerted on the diaphragm as feed is supplied. Preferably the feed cavity 28 expands according to the feed volume and may help to reduce the foaming properties. Keeping the feed cavity volume to a minimum may pressurise the feed on entry to the cavity 28 and allows a degree of pre-filtration which may induce filtercake formation from the upper end of the filter medium to the other. The fluid used to apply the pressure may form part of a hydraulic reservoir (Fig 9, 46) and during operation may be contained within a pressure chamber (Fig 2, 18). Filtercake may collect on a cylindrical filter medium 21 and may be removed by a blast of air from a discharge inlet (Fig 8, 31).

Title: Method to reduce water saturation in near-well region
Inventor: REPPERT TODD R
IPC: E21B43/32
Filed: 1999-10-26
Abstract: This invention provides a method for reducing the water saturation in the near-well region. Along with various well treatment possibilities, one application of this invention increases the injectivity rate of a substantially nonaqueous fluid into a subterranean formation. The preferred embodiment uses this invention to increase the injectivity of solvent gas into an oil-bearing formation for enhancing the amount and/or rate of oil recovery from the formation. The method includes injecting a second fluid into the near-well region of the injection well to displace at least a portion of the water from that region. Displacement of the water and subsequent displacement of the secondary fluid allow maximum injectivity for the primary solvent being injected for oil recovery.
