20130103319 | METHODS FOR DETERMINING WELL CHARACTERISTICS AND PORE ARCHITECTURE UTILIZING CONVENTIONAL WELL LOGS - Methods, computer readable medium, apparatus, and program code for determining well characteristics and pore architecture for a hydrocarbon well utilizing data available from conventional/standard electronic well logs, are provided. An example of a method can include determining the value of well constants from well log data to include calculating water saturation, free water level location, wettability, and pore throat heterogeneity, and calculating pore architecture at log resolution responsive thereto. This can be accomplished, for example, by accessing well log data from a conventional well log, determining a linear regression line responsive to parameters calculated from the well log data, the linear regression line having a slope and an intercept, and determining a value of each of a plurality of well constants responsive to a value of the slope and of the intercept of the linear regression line. | 04-25-2013 |

20100276342 | METHOD OF FROTH FLOATION CONTROL - A method of controlling operation of a froth floatation cell for separating substances comprises introducing gas into liquid in the cell, creating a froth controlling gas flow rate into the cell in order to maximise gas recovery for the cell. | 11-04-2010 |
20140110311 | METHOD AND APPARATUS FOR FROTH FLOTATION CONTROL - A method of controlling operation of a froth flotation cell comprises introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, which froth overflows and leaves the cell at an overflow point, wherein the froth has a froth height from the level of the overflow point to the upper surface of the froth, measuring values of the froth height for two values of gas flow rate into the cell, measuring values the velocity at which the froth overflows at the overflow point for two values of gas flow rate into the cell, calculating a gas flow rate into the cell that optimises gas recovery, by treating the measured values of froth height and measured values of froth velocity independently, and setting the gas flow rate into the cell to be the calculated flow rate into the cell that optimises gas recovery. | 04-24-2014 |

20130299394 | METHOD AND APPARATUS FOR FROTH FLOTATION CONTROL - The invention provides a method of controlling operation of a froth flotation cell, the method comprising: introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, the froth having a depth from the surface of the liquid to an overflow point at which the froth overflows and leaves the cell; and controlling the froth depth to optimise the gas recovery with respect to the froth depth. Optimisation of the gas recovery with respect to the froth depth leads to the recovery of a froth concentrate of both high grade and high product recovery. | 11-14-2013 |
