Abstract: Apparatus and methods are disclosed for recovering hydrocarbonaceous and additional products from oil/tar sands. The method includes the steps of forming a hole in a body of oil or tar sand, positioning an apertured sleeve within the hole to minimize fill-in of the sand, positioning a gas inlet conduit into the apertured sleeve, and introducing a heated, pressurized processing gas into the sleeve through the gas inlet conduit, such that the heated, pressurized processing gas penetrates into the sand through the apertures, thereby converting bitumen within the sand into hydrocarbonaceous products. The processing gas and hydrocarbonaceous products are withdrawn as effluent gas through the hole under relative negative pressure. The apertured sleeve may be installed in sections into the hole as the hole is formed. The apertures in the sleeve may be holes with a circular or other geometry or elongate cuts. In particular, the apertures in the sleeve are elongate cuts oriented more vertically than horizontally; that is, more aligned with the axis of the sleeve. A mesh screen may be supported between the apertured sleeve and the body of oil or tar sand.

Abstract: The invention relates to a method of design of ruled surfaces, comprising a step of accessing data defining guiding curves P(u) and Q(v) (S 110) and a cost function f(t, w) (S120). Given P(u) and Q(v), the unknown coupling is a parameterized curve s ~(t(s), w(s)). The method further comprises defining (S200) an objective function of the type J = J( f, t, w), involving both f(t, w) and coordinates t, w of the coupling curve. Then, optimizing the objective function J makes it possible to obtain the target coupling curve (S400). Finally, a ruled surface S(s,.lambda.) =.lambda.Q(w(s)) + (1- .lambda.)P(t(s)) is provided (S500), according to the guiding curves P(t(s)) and Q(w(s)), composed with the coordinates t, w of the coupling curve previously obtained. In addition, the objective function is further constrained at the optimization step (S200 - S400) such that arguments t, w of the cost function f(t, w) are regulated by a regulation function µ. The invention generalizes to any surface defined by guiding curves and further concerns a computerized system and a computer program product comprising means adapted for implementing the method of the invention.
