Abstract: A method is proposed for heating a hydrocarbons reservoir, comprising the provision of an installation comprising: a first wellbore equipped with an injection string fitted with an adjustable choke and an extraction string fitted with an adjustable choke, a set of sensors, intended to measure physical variables, an automatic device making it possible to control and monitor the operation of the installation; the circulation of steam from one string to the other; the control of the steam injection flow rate in function of a target value; the keeping of a set of physical variables within a predetermined range of values by continuous action of the automatic device on the choke of the injection string, and on the choke of the extraction string.

Abstract: The table has two telescopable supports (4) each with a flange (22) at the upper end. To the flanges (22) there is screwed fast a tub (6). In the rear part of the tub (6) there is present a cable channel. The table plate (8) is horizontally shiftable on the tub, so that the cable channel is accessible. With an extensible crank (62) over a toothed-belt gear two threaded spindles are synchronously actuated in the supports (4) for the height adjustment. The table is rapidly resolvable into space-saving parts, without its being necessary for the height-adjusting mechanism to be disassembled. The table is convenient to operate.
