Coiled tubing tools for jet drilling of deviated wells |
April 4, 1995 |
| Low-cost, medium-curvature, deviated drainholes are drilled from a vertical cased well in soft formations, using the jet-drilling technique with a coiled-tubing. The high-velocity liquid jet is oriented at a small angle from the axis of the coiled tubing in the selected direction. The je |

Process for conserving steam quality in deep steam injection wells |
February 4, 1992 |
| The degradation of steam quality due to heat losses prior to its injection into a heavy oil reservoir is reduced by a process utilizing the heat contained in a stream of reservoir fluids produced from the same reservoir, following a cycle of steam injection. These hot reservoir fluid |

Catalytic downhole reactor and steam generator |
October 1, 1991 |
| A Downhole catalytic Methanator reactor assembly is hung within the cemented casing of a vertical well for the purpose of producing large volumes of high quality steam and oil soluble gases for injection into horizontal drainholes drilled into a deep Heavy Oil reservoir, in order to |

Heavy oil recovery process |
November 17, 1987 |
| Heavy oil is recovered from deep reservoirs by injection of a gaseous mixture containing hydrogen, steam and in some cases oil soluble gases and/or vapors. This mixture is produced by a reversible exothermic catalytic reaction in a down-hole reactor and injected into a well drilled, |
