ESP installed below and between perforations in commingle configuration. Methods, Procedures, Process: Different downhole configuration having gas separators, gas handlers, and taper...

... Submersible Pump (ESP), one in-well and other in mud line skid, was developed and installed. All this innovations and best technologies used together made Atlanta a successful case of heavy oil production in ultra-deep waters, triggering huge resources around the world. wax remediation flow assurance...

New perforating procedure in monobore completion by activating anchored guns when ESP is running in hole, then pump is placed to the designed depth, this new operational sequence helped to prevent ESP damage due to high pressure is needed to activate firing head during workover operations when a low...

... Abstract In the pursuit of more productivity, Petrobras has been using more and more ESPs (Electric Submersible Pumps) on its subsea wells, especially on heavy oil fields, where the gas-lift is not as attractive as that method. Those scenarios are very common in the Campos Basin, particularly...

... or Pumping Unit (MOBO) caisson ESPs installed inside Artificial Lift Manifolds (ALMs) 1) . Oil from the individual subsea wells flows into the MOBO caisson ESPs and from there the ESPs pump the oil up to the floating production, storage and offloading (FPSO) vessel. The ALMs are located approximately 5...

... such as bentonite and naturally occurring formation clays. Because these acid treatments are corrosive, it is common practice in low-pressure wells to pull out the electrical submersible pumps (ESPs) prior to performing a stimulation treatment to prevent damage to them. Doing so results in additional costs...

...Introduction One of the mayor objectives of "PDVSA", the Venezuelan state Oil Company, is to develop and increase the production of Tomoporo district (located in the Trujillo state of Venezuela). In order to achieve this goal, PDVSA has been implementing Elecrical Sumersible Pumps (ESPs...

... In this context, the selection, operation and optimization of the different Artificial Lift Systems (ALS) plays an important role for following the development of the basin. This paper describes the best practices, experiences and trends, using ALS as Progressing Cavity Pump(PCP), Electric Submersible Pump(ESP...

One of the main operational issues related to the realisation of the value expect from this type of project is to ensure that all of the required information is correct. This is not a little feat! This paper describes the challenge of the federation of the information...

... In Oritupano and Leona fields there are areas with medium-heavy crude in the upper Oficina Formation, and an extra heavy crude at its bottom section. There are vertical, directional and horizontal wells producing with ESP's, some of them gravel packed. ESP's application began with standard...

... Abstract Since 1993, Electrical Submergible Pumps (ESPs have been applied with excellent results in the cold production of heavy crudes (9.5 API) in about 70 horizontal wells in the hamaca area of the Orinoco Faja. Over the three year production life of these wells, production declinations due...

... have created the necesity to review the latest available technology of different lifting methods and specially that of the electrical submergible pump (ESP). Few studies in the area of heavy crude oil production optimization using ESP's as a lifting method have been published. This paper discusses...
