摘要:
Methods and systems receive a print job and determine whether the print job specifies one or more extended gamut color marking materials. The extended gamut color marking materials comprise marking materials having colorants other than standard colorants. The standard colorants consist of cyan, magenta, yellow, black (CMYK). When the print job does not specify one or more of the extended gamut color marking materials, the methods and systems determine whether the print job will perform better with one or more of the extended gamut colorants in addition to the standard colorants. The methods and systems print the print job use the extended gamut colorant(s) and the standard colorants when the print job specifies the extended gamut color marking material, and when the print job will perform better with one or more of the print system's extended gamut colorants in addition to the standard colorants.

Methods of performing print engine calibration create a color space conversion equation for a scanner of a class of printing devices, print test patches on a sheet, and scan the test patches using a scanner of the printing device to produce a scanned RGB value for each test patch. Such methods convert each scanned RGB value to an XYZ pseudo space using the color space conversion equation to produce XYZ values. These methods compare the XYZ values to second XYZ values of white paper to generate DeltaE curves for each of the test patches relative to white paper. The DeltaE curves are interpolated to form an equivalent aim curve. After the equivalent aim curve is determined, the methods periodically calibrate the same or an additional printing device that is within the class of printing devices using the color space conversion equation to produce second XYZ values.

A method for reducing the time during which steam moves in a lateral direction between two parallel superimposed horizontal wells when utilizing a Steam Assisted Gravity Drainage (SAGD) process. Foam is added while injecting steam into an upper horizontal well once steam breakthrough occurs in an interwell region. Foam enters the interwell region thereby causing an increased pressure gradient. This increased pressure gradient adds to the gravity force thereby providing a greater interstitial oil velocity which increases oil drainage between wells during startup.

A solvent stimulation process whereby a viscosity reducing agent is circulated through a horizontal well via a production string. Said agent exits the production string and enters an annulus formed by said string and a liner. Said agent diffuses into the reservoir at a pressure below the reservoir pressure. As said agent diffuses through the reservoir under the influence of a concentration gradient, it reduces the oil's viscosity and makes it mobile. Simultaneously, oil of reduced viscosity migrates into the well under a pressure drawdown influence. A pseudo steady state production rate is achieved when convective movement of the oil of reduced viscosity is exactly counterbalanced by the diffusional rate of the viscosity reducing agent in a stimulated radial zone along said well. This stimulates a large volume of oil through the extensive surface area of the wellbore thus producing increased volumes of hydrocarbonaceous fluids from the reservoir.
