LINERS EN COMPLETACIONES DE POZOS

A liner is a string of casing that does not reach the surface. Liners are hung on the intermediate casing by use of a liner-hanger. In liner completions both the liner and the intermediate casing act as the production string. Types of Liners Drilling liners are used to isolate lost circulation or abnormally pressured zones […]

ADVANTAGES OF DIFFERENT ARTIFICIAL LIFT SYSTEMS

MECHANICAL PUMP • System design relatively simple.• Units can be changed to other wells at a minimum cost.• Efficient, simple and easy to be operated.• Applicable for slim hole (small diameter wells) and multiple completions.• It can pump a well at very low pressure (depending on depth and flow)• The system is naturally vented for […]

DISADVANTAGES OF ARTIFICIAL LIFT SYSTEMS

In an earlier date had posted about the advantages of artificial lift systems, this post will find the disadvantages of each system: MECHANICAL PUMP Unobtrusive in urban locations.Heavy and bulky ne Offshore operations.Susceptible to problems of paraffins.The tubing can not be covered against corrosion.Presents problems of friction in deviated wells.The high production of solid represeta […]
