The assembly of the Electrical Submersible Pump unit and cable connection must be carried out by the Electrical Submersible Pump (ESP) supplier’s field engineer. In order to comply with the requirements of the manufacturer’s warranty any instructions or recommendations given by the field engineer should be followed. The engineer should be allow sufficient time to … ESP – Assembly pump / motor
Electrical Submersible Pump (ESP) completions are not as tolerant to changes in downhole conditions as other forms of artificial lift. Care must be taken to minimize the well PI impairment. The density of the completion fluid should be reduced to the lowest value permissible and consideration given to relaxing the requirement for maintenance of a … ESP – Preparation of the Well
The transport and handling of Electrical Submersible Pump (ESP) components should reflect the high cost and fragile nature of the equipment. Flexing resulting in permanent distortion of the equipment will cause accelerated wear when the Electrical Submersible Pump is operated. Bearings manufactured from hard, brittle materials such as ceramics are also subject to damage from rough … ESP – Transport
Subsurface safety valves (SSSVs) are installed in the wellbore of hydrocarbon producing wells to shut off the production flow to the surface in case of an emergency. The importance of the correct installation of these valves to ensure well production flow is shut in during an emergency can not be over emphasised. Improvements in valve … Sub-surface safety valves (SSSV)
The length and composition of sub-assemblies is usually dictated by the space and handling equipment considerations. They will ideally be made up and tested (both functionally and hydraulically) in a suitable base workshop. On site make-up should only be performed if the correct make-up equipment is available to ensure correct make-up torque and no damage … Sub-assembly preparation and make up
The following installation considerations apply to all threaded connections if mishaps are to be avoided: drift check and inspect connections before running; properly apply correct thread dope; backout and re-inspect connections that are stabbed in misaligned position; avoid high makeup speeds and use correct torque; use pup joint, couplings and cross-overs of the same tubular … Tubing running and testing
Guidelines for storing, handling and transporting completion tubing 1 Storage The design of pipe racks depends on local conditions (load capacity, degree of permanency, etc). Racks can be made with pipe supports (stringers) set on concrete or wooden bases. Drilltec aluminium racks should be considered for certain tubulars such as CRAs (Corrosion Resistant Alloys). Spacing … Tubing storage, handling and transport
this article presents the main operational and safety precautions to be taken when installing a xmas tree. 1. General Precautions There are many methods of landing the tubing and leading control line(s) from the wellhead. Full instructions for this operation will be contained in the programme or in written standard procedures, however precautions to be … Xmas tree installation
The following 5 Packer setting mechanisms are discussed in this article: Compression set anchor packer Mechanically set compression packers Mechanically set tension packer Hydraulic set tension/compression packer Action of hydraulic hold-down 1. Compression set anchor packer The anchor packer is the simplest of the compression packers. In the running-in position, a collet latch is in … Packer Setting Mechanism
The following provides information based on past experience of the retrievability of packers, which provides general trends and guidelines for the execution of such activities. However, every well is different and as such hard and fast rules are not possible to giive. (KW: packer, retrievability, completion, production, well engineering, construction) ·The four biggest influences on … Packers retrievability
