A rod-based well screen is formed in place on a perforated pipe base by wrapping wire around the pipe base and a plurality of rods located around the outside of the pipe. The wire is welded sequentially to each individual rod as it is wrapped around the pipe. The welding and ground electrodes engage the wire and the rods respectively. The rod engaging ground electrode is positioned a short distance ahead of the wire being wrapped around the rods and the pipe base. The ground electrode includes a plurality of contacts. Each contact is mounted to pivot toward and away from a rod. Springs urge each contact toward a rod to hold the rod against the outside surface of the pipe base and to maintain good electrical contact between the contact and the rod. Each contact has a groove to guide the rod into position for welding to the wire.

Manufacturing of sand screens

Apparatus associated with the production of hydrocarbons comprising a joint assembly comprising a main body portion having primary and secondary fluid flow paths, wherein the main body portion is attached to a load sleeve assembly at one end and a torque sleeve assembly at the opposite end. The load sleeve may include at least one transport conduit and at least one packing conduit. The main body portion may include a sand control device, a packer, or other well tool for use in a downhole environment. Included is a coupling assembly having a manifold region in fluid flow communication with the second fluid flow path of the main body portion and facilitating the make-up of first and second joint assemblies with a single connection.

Wellbore method and apparatus for completion, production and injection

Method of making a sand screen on a base pipe

Disclosed herein is an assembly for use in a wellbore which includes a base pipe; a filter medium surrounding at least a portion of the external surface of the base pipe; and an internally profiled sleeve surrounding at least a portion of the filter media. Also included is a method for attaching a hardware accessory to a sand screen assembly which includes providing a base pipe having an inner surface and an outer surface; surrounding the outer surface of the base pipe with a filter medium; engaging the sleeve with the filter medium; and connecting the hardware accessory to the sleeve. Also included is a downhole apparatus which includes a basepipe, where at least a portion of the external surface of the basepipe is profiled; and a sleeve mounted external to the basepipe, where the internal profile of the sleeve corresponds to the external profile of the basepipe.

A technique protectively arranges at least one cable on the outside of and along at least one pipe section of a pipe string. The cable is secured to at least one cable protector coupled to the outside of at least one pipe section of the pipe string. The cable protector comprises a cable-retaining strip. The cable-retaining strip is provided with at least one continuous cable track arranged along the cable-retaining strip, the cable track opening outwards relative to the pipe section. The at least one cable is also secured to the at least one cable track, whereby the cable is protected from the external environment.

Cable-protective pipe section, a method of protectively arranging at least one cable on the outside of the pipe section and use of a device for protecting the cable

A device for an underground well, typically a petroleum well (), wherein, in the uncased inflow portion () of the well, there is placed an inflow pipe, possibly in the form of a strainer pipe () comprising a strainer/perforated outer mantle (), a main pipe () located within and a number of preferably axial spacer strips () spaced apart about the external periphery of the main pipe and arranged to support the strainer mantle (), whereby there are, in the space defined by the strainer mantle () and the main pipe (), channelsbetween the spacers (), and in one or more of the channels, there extends at least one cable, pipe or hose ().
