  • Patent number: 9045841
    Abstract: In a copper electroplating apparatus having separate anolyte and catholyte portions, the concentration of anolyte components (e.g., acid or copper salt) is controlled by providing a diluent to the recirculating anolyte. The dosing of the diluent can be controlled by the user and can follow a pre-determined schedule. For example, the schedule may specify the diluent dosing parameters, so as to prevent precipitation of copper salt in the anolyte. Thus, precipitation-induced anode passivation can be minimized.

  • Publication number: 20140260993
    Abstract: A multi-phase separation apparatus shapes fluid flow in a flow shaping line preferably shaped to have a plurality of loops with consecutively decreasing diameters. Shaping the two-phase flow drives the heavier, denser fluids to the outside wall of the flow shaping line and allows the lighter, less dense fluids such as gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall, an exit port on the inner wall permits a majority, if not all, of the gas, along with a minimal amount of liquid, to be diverted to a conventional gas-liquid separator at a flow rate much lower than the total flow rate within the flow shaping line. The remaining liquid flow in the flow shaping line is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.

  • Patent number: 8602128
    Abstract: Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement.

  • Publication number: 20130277113
    Abstract: A system and method for solid-liquid separation and analysis of drilling fluids is described. The method includes heating a retort body to a pre-determined temperature, with an inner wall of the retort body at least partially defines a chamber within the retort body. A sample drilling fluid may be automatically injected into the inner chamber, and a film of the sample drilling fluid may be generated on the inner wall of the retort body. The film may be separated into a solid portion and a vapor. The method may further include collecting vapor using a vent that provides fluid communication with the inner chamber, and condensing the vapor into a fluid portion of the film. The volume of the fluid portion may them be automatically measured.

  • Patent number: 8533974
    Abstract: The present disclosure is generally directed to systems that are used for reclaiming components of wellbore cuttings material. In one illustrative embodiment, a system is disclosed that includes, among other things, a dryer that is adapted to receive a drill cuttings mixture that includes drilling fluid and cuttings material, the dryer being further adapted to treat the drill cuttings mixture by drying the cuttings material below a preselected moisture content level.

  • Patent number: 8496063
    Abstract: A method and device for recovering drilling fluid used in connection with the provision of a subsea well, in which the drilling fluid is circulated from a vessel on a sea surface via a drill string and out through a drill bit into an annulus which is defined by a borehole and the drill string. The device includes a filtering device which is connected, in respect of fluid, to an annulus and which is arranged to contain drill cuttings and drilling fluid. A fluid line extends from a portion of the filtering device to the vessel, the fluid line being arranged to carry drilling fluid which has been separated from the drill cuttings back to the vessel.

  • Patent number: 8469116
    Abstract: Techniques for controlling drilling fluid cleaning apparatus that reclaim lost circulation material from spent drilling fluid are disclosed. In one embodiment, a system includes a tank, a density separation device, and a fluid density control system. The tank holds spent drilling fluid containing drilling fluid, lost circulation material, coarse solids and fine solids. The density separation device is coupled to an outlet of the tank. The density separation device provides an overflow stream and an underflow stream. The overflow stream contains less dense material than the underflow stream. The fluid density control system is configured to adjust the density of the spent drilling fluid provided to the density separation device by recirculating a portion of the underflow stream into the tank.

  • Publication number: 20130062122
    Abstract: A method of maintaining a desired temperature at a location in a well can include adjusting fluid circulation parameters, thereby reducing a difference between an actual temperature at the location and the desired temperature. A well system can include at least one sensor, an output of the sensor being used for determining a temperature at a location in a well, and a hydraulics model which determines a desired change in fluid circulation through the well, in response to the temperature at the location being different from a desired temperature at the location. Another method of maintaining a desired temperature at a location in a well can include adjusting a density, solids content and/or flow rate of a fluid circulated through the well, thereby urging a temperature at the location toward the desired temperature.

  • Publication number: 20120325557
    Abstract: A water/slurry containment device for core drilling can contain and allow water/slurry to be extracted while the coring is occurring rather than allowing a puddle to form with more extensive cleanup required afterward. The device contains the water/slurry mix so that none escapes the confines of the device, so that water can be used in the core drilling. Water is essential to the life of the diamond coated bit and it keeps dust and noise to a minimum. The device includes a base plate with a collector ring that can rest on a surface to be core drilled. A notch can be cut in the collector ring and/or base plate to allow water and slurry to be removed from the device while core drilling.

    Abstract: Cutting wash apparatus includes a wash tank (11) having side walls (15) converging to an inclined lower floor (16) and containing an air agitated wash solution including a surfactant. A cyclone separator (27) receives an oil-based mud and cutting-containing slurry through inlet (30), passing mud to an outlet (31) and a cuttings-rich component to the wash tank (11). A skimmer (13) removes wash overflow and a mud and slurry fines raft floated by the agitation, and passes this to a separator (18). Separated wash liquid is aerated and returned by pump (19) to injection points (28, 29) to recycle wash and provide the agitation. An auger (23) operates in a casing (21) opening into the tank (11) and extending upward of the wash tank and having an upper end discharge outlet (38). Additional aeration and agitation air is injected through air injection bars (45).
