Guidelines for starting and operating an Electrical Submersible Pump (ESP) system. 1 Personnel A field engineer from the pump supplier should be present whenever an Electrical Submersible Pump is to be started for the first time. The field engineer should remain on the location until the well has stabilised and the Electrical Submersible Pump is … Starting up and operating an Electrical Submersible Pump (ESP)

Retrieval of an Electrical Submersible Pump (ESP) requires similar precautions to those taken during installation and some additional points should also be considered when retrieving ESPs. Analysis of the reasons for ESP failure may not be possible if additional damage is sustained by the equipment during retrieval from a well, or during subsequent storage and … ESP – Retrieving Electrical Sumbersible Pumps

Prior to leaving location it is recommended that a well test is carried out to the Electrical Submersible Pump using a dedicated test separator with the rig on site. This will ensure that any immediate problems can be rectified without having to move a rig back. In addition the use of a dedicated test separator … ESP – Testing

Proper handling and running procedures are essential to ensure cable reliability. The majority of cable failures are caused by damage resulting from improper handling. The ESP cable is often the most expensive item in an Electrical Submersible Pump (ESP) system. It is easily damaged if subjected to incorrect handling procedures. The weight of a drum … ESP – Cable handling

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
