摘要:
A method of ameliorating two-phase flow segregation during wet steam injection in a vertical injection well wherein a compartmentalized tray of variable depth is utilized. This tray traps a liquid phase of the steam near each perforation. A hole within the tray allows steam to pass through to a lower level in the well. In this manner, the liquid phase is held up near the perforations. Steam and water thus pass into the formation uniformly at each perforation. The degree of segregation may be controlled by the tray's depth. A deeper tray allows more water to be trapped near the upper perforations. A shallow tray favors segregation within the wellbore. More than one tray can be used.

A computer-implemented method for imaging of spot colors within a document using a spot color editor is provided. The method includes determining a spot color formula, using a spot color editor, for providing a colorimetric match to a desired spot color in a print job, wherein the spot color is within a color space and the spot color formula includes colorant values for each color in the color space; printing a test image of the spot color with the determined spot color formula for analysis, wherein the color composition of the spot color test image is analyzed by a user to determine whether desired image quality is achieved; and determining an updated spot color formula for providing a colorimetric match to the desired spot color in the print job based on a received input, if the desired image quality is not achieved.

A spot color rendering system and method that incorporates spot color press emulation color transformation to preserve spot color on a target rendering device. A spot color rendering option implemented in a graphical user interface can be selected in order to render the spot color via an intermediate emulation space. The spot color name calls can be first associated with a color value in an ICC profile connection space (PCS), as CIE L*a*b* or XYZ. A database relation of the spot color name with its associated PCS numerical value enables association of the name with the resultant color transformed output. Thereafter, a color transformation with respect to the spot color value can be performed in order to compute a color on an emulation press and then the color can be preserved to the target rendering device. Such an approach enables a color consistent rendering to the target rendering device similar to that of the emulation press.

摘要:
A conduction heating, gravity assisted, single well, process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam and a gas soluble in hydrocarbonaceous fluids are circulated into the wellbore at or below the reservoir pressure through an upper perforated conduit of the horizontal wellbore. Circulation is continued so as to allow steam to heat the reservoir by conductance while gas enters the hydrocarbonaceous fluids. Thus, heated hydrocarbonaceous fluids having a reduced viscosity flow from the reservoir around the horizontal wellbore where the fluids are produced to the surface by a lower conduit within the horizontal wellbore. The lower conduit is open along its length so as to be in fluid communication with the reservoir for the length of the horizontal wellbore.

摘要:
A method for recovering viscous oil from a formation having a bottom water zone below an oil containing zone. Steam is directed into the bottom water zone thereby heating this zone and an oil containing zone thereabove. Afterwards, steam injection is ceased and a gellable composition is directed into the bottom water zone where it forms a solid gel. Once the solid gel has formed, steam is injected into the bottom water zone where the solid gel causes it to flow upwardly into the oil containing zone. Oil, water, and steam are removed via a recompleted producer well.
摘要:
A method to reduce water coning in viscous oil formations during primary oil production wherein a horizontal wellbore is heated by circulating steam therein thereby heating a radial area near the wellbore. Near wellbore heating alters a pressure profile in the radial area near the wellbore. Reduced inflow pressure gradients near the wellbore flatten out a pressure sink associated with the wellbore. This reduces substantially water coning which allows more oil to be produced before high water production begins.

A foam/steam injection method for forming fractures is a for reservoir penetrated by a horizontal wellbore. Steam is injected into said wellbore at a pressure sufficient to fracture the formation. Water which is used to make the steam contains a foamable composition in an amount sufficient to make a foam upon contact with steam. Steam and foam enter the wellbore and create a fracture in an oil-rich zone. Thereafter, foam blocks further steam entry into the created fracture which causes another fracture to form at a second interval along the horizontal wellbore. These steps are repeated until a fracture system is made along the length of the wellbore.
