The outer phase of the dual-functional breaker emulsion is oil, e.g. a mineral oil, containing an oil-soluble surfactant that will, over time and with heat, break the VES portion of the gel. As it does so, the polymer breaker in the internal aqueous phase will be released to then break the polymer portion of the gel. The polymer breaker will not start to break the polymer gel before the oil-soluble surfactant starts to break the VES gel. The overall breaking using the emulsion is slower as compared to introducing the polymer breaker and the oil-soluble surfactant in a non-emulsified form. | 2010-12-16 |

20100314118 | Liquid Crystals for Drilling, Completion and Production Fluids - Fluids containing liquid crystal-forming surfactants or polymeric surfactants, or polymers, or complex polymers or copolymers, or graphite nanotubes or Janus particles in a polar and/or non polar liquid, and optionally, co-surfactants, are useful in drilling, completion and production operations to give increased viscosity (solids suspension ability) and/or decreased fluid loss, as compared to otherwise identical fluids absent the liquid crystals. These liquid crystal compositions contain organized micelles. The liquid crystal-containing fluids are useful in completion fluids, fracturing fluids, formation damage remediation, waste management, lost circulation, drilling optimization, reducing trapped annular pressure during the hydrocarbon production process, well strengthening, friction and drag reducers, fluids introduced through an injection well, for geothermal wells, and the controlled release of additives into a wellbore, at a subterranean formation or at the oil production facilities. | 2010-12-16 |
20100314119 | APPARATUS AND METHODS FOR WELL-BORE WALL SURFACE FINISHING - An apparatus for modifying the wall surface of a borehole drilled through an underground formation. The apparatus comprises a tool body that can be introduced into the borehole using a conveyance system so as to be moveable along the borehole, and one or more members arranged so as to be able to be urged against, and moved across at least part of the borehole wall in order to work the surface thereof and modify its properties. A method of modifying the wall surface comprises positioning the tool body in the borehole at a location of interest using the conveyance system, urging the members against the borehole wall with sufficient force to modify the properties of the surface thereof, and moving the members across the surface of the borehole wall. | 2010-12-16 |
20100314120 | Dual Acting Rod Piston Control System - A downhole tool is hydraulically actuated through a control system that features rod piston(s) that are double acting. The piston bore is in a single housing component with an annular cavity that provides access to all piston bores to move the pistons in a first direction. The housing component that has the piston bore also includes an internal sleeve in a passage in the housing. A second control system connection communicates with a sealed annular space defined between the sleeve and the passage wall that holds the sleeve. A series of radial ports communicate from the annular space into each piston bore on the opposite side of each piston from the annular cavity so that each piston is double acting with a bore in a single housing component. | 2010-12-16 |
20100314121 | WELL APPARATUS - Well apparatus comprises a tower, and a support for supporting well intervention, completion, testing, or drilling equipment, the support being attached to the tower and being movable laterally from a parked position on the tower, where preparation of the equipment can be carried out without occupying an operational area where the equipment is to operate on the well, and an operational position in the operational area, and the support being arranged to be lowered or lifted, the apparatus further comprising a guide mechanism for guiding the support so that as the support is—lowered or lifted it is guided along a path involving lateral movement from the parked position to the operational position in the operational area. | 2010-12-16 |
