摘要： A method of heating gas being produced in a well reduces condensate occurring in the well. A cable assembly having at least one insulated conductor is deployed into the well while the well is still live. Electrical power is applied to the conductor to cause heat to be generated. Gas is allowed up past the cable assembly and out the wellhead. The heat retards condensation, which creates frictional losses in the gas flow.

摘要： A reinforcing interface between the stator and its housing in a progressing cavity pump is created from ribs extending inwardly into the stator from the housing inner wall that can be longitudinally oriented or spirally oriented. Alternatively, the housing wall can have grooves into the inner wall that are made more bulbous further into the housing wall from the groove inlets so that when filled with stator material a long and continuous grip is obtained with either the wall groove embodiment or the internal rib embodiment.

摘要： A cable for transmitting electricity for use with an electric submersible pump has a plurality of conductors for conducting electricity along the length of the cable. A first layer of insulation surrounds each of the conductors. A jacket, or second layer of insulation, surrounds all of the conductors and the first layer of insulation. Both the first layer of insulation and the jacket insulation are comprised of an polymeric compound. At least one of the insulation layers has filler material dispersed therein, the filler material having a higher level of thermal conductivity than the insulation layer it is contained in.

摘要： Conductors are placed in insulator which acts as a spacer/centralizer for the conductors, which are in turn mounted within tubing. The void spaces between the insulator and the tubing inside wall can be filled with a sealing material. Alternatively, the voids around the substantially centralized conductors can be used as flow channels for the transmission of fluid pressure to a remote location, such as downhole. The conductors are protected because they are kept away from the tubing wall and can be further protected by the addition of the sealing material.

摘要： A multi-conductor parallel array armored electrical power cable includes a pair of longitudinal spring members. The longitudinal spring members help maintain compactness between conductor assemblies within the power cable after a protective armor has been applied. The longitudinal spring members are installed between the outer most conductors and the armor of the cable. The unique shape of the spring members along with their placement during assembly absorb much larger tangential forces normally accepted when applying the armor to the cable. The spring members become distorted from their original shape and, as the armored cable is further formed to its final shape, the longitudinal spring members substantially return to their original shape to urge the conductor assemblies together.

摘要： An electric motor has a housing with a plurality of stator discs. The discs have slots that align with one another, forming passages. A dielectric film tube inserts into the slots, each of the tubes having a continuous circumference. Each tube has a nonmeltable dielectric film layer of high temperature insulation. The dielectric film layer has overlapping edges and is bonded to a carrier layer of a meltable material. The tubes may be inserted into the slot passages by drawing a vacuum in the interior of each tube, causing it to collapse so that it can be readily inserted.
