Abstract: Alkaline earth metal scales, especially barium sulfate scale is removed from a well (18) (the wellbore (30) and the adjacent formation (10)) by contacting the scale with a scale-removing solvent and thereafter sparging the solvent with air or inert gas to dissolve the scale. The sparging aids in achieving a flushing action by the solvent relative to the scale thereby enabling the solvent to more effectively dissolve the scale in the well (18). Temperature and caustic compatible surfactants (anionic and non-ionic) may be used in the solvent to generate a column of foam which increases the extent of cleaning oil from the scale surfaces, enabling the solvent to more effectively remove the scale.

Abstract: A robot for sealing and blocking pipes which are subject to very high pressure. The robot comprises a counter-pressure device below the main blocking portion for simultaneously acting on the inner wall, at depth in the pipe, by expansion caused by a single linear movement of a tapered shaft in a cylinder having therein a tapered bore; said shaft having a diameter which is 50 % greater than the difference between the inner taper diameters of the two ends of the cylinder, which cylinder has a slot running the full length thereof and is controlled by hydraulic jacks; a centre pipe allowing oil flow and normalising the upward pressure during the insertion process; and two pantographs for centering the system in the well in spite of the very high pressure. The high pressure in the well helps ensure blocking of the system.
