대표청구항 ▼

A method for creating a seal between two tubulars in a wellbore is provided. In one aspect, the method allows for the top end of a first tubular to be sealingly mated to the bottom end of a second tubular. The first tubular is positioned at a selected depth within the wellbore. An expander tool is then run into the wellbore, and the top end of the first tubular is expanded along a desired length. The inner surface of the top end is expanded from a first diameter to a second diameter which will mate with the lower end of the second tubular. The expander tool is removed, and the second tubular is run into the wellbore. The bottom end of the second tubular is then sealingly mated with the top end of the first tubular. In one embodiment, the first tubular defines a string of casing which is expanded to create a polished bore receptacle for receiving a string of production tubing. or to cause heat to be generated at a temperature within the production tubing that is sufficient to retard condensation; (e) flowing gas up the production tubing past the cable assembly and out the wellhead; and providing the casing with an inner diameter having a heat reflective coating. 16. A method of reducing condensate occurring in a gas well, the well having a production tubing suspended within casing, defining a tubing annulus between the casing and the tubing, the method comprising: (a) providing a heater cable assembly having three insulated conductors located within a string of coiled tubing; (b) coiling the cable assembly on a reel and transporting the cable assembly to a well site; (c) shorting lower ends of the conductors together; (d) installing a pressure controller at an upper end of the production tubing, sealing around the cable assembly with the pressure controller, and deploying the cable assembly from the reel into the production tubing while well pressure still exists within the production tubing; (e) with a vacuum pump located at the surface of the well, reducing pressure within the tubing annulus to below atmospheric pressure; (f) flowing gas up the production tubing past the cable assembly and out the wellhead; and (g) applying electrical power to the conductors to cause heat to be ge
