Argentina holds technology workshop on artificial lift systems
More than 130 participants from 13 countries attended SPE’s Advanced Technology Workshop on artificial lift systems earlier this year. Over the course of three days and nine technical sessions, attendees representing a nearly equal split between operating and service companies were exposed to all aspects of artificial lift systems and saw the full interactive circle of technologies and competencies.
The Keynote Speaker was Mary Corsaro, Manager of Processes and Projects Engineering Group for Pan American Energy. Corsaro discussed how Pan American’s Well and Field Facilities Automation Project has evolved at the Cerro Dragon field, Argentina, with particular emphasis on project challenges and benefits, how to identify the internal clients, how to sell the project to management, and how to implement it within the organization.
Throughout the workshop several noticeable trends were discussed both during the presentations and the session breaks. One of these was the increase in innovative artificial lift methods, borne out by the increase in crude oil prices over the past several years. Several creative innovations were discussed, including the Vann System, which utilizes standard reciprocating downhole pumps and cables to convey the reciprocating motion. Other innovations discussed were the Recoil System that utilizes a long hose into which the produced fluid is lifted, the swab system, and concentric Jet Pump completions. What were considered uneconomical methods in the past have recently become extremely economical.
In addition to novel and innovative artificial lifting methods, the need to optimize and automate wells was paramount in the minds of many operators. It is no longer sufficient to just measure basic parameters such as stroke length and strokes per minute, pump revolutions per minute, amperage, and fluid levels. The trend is moving towards multipoint pressure-temperature measurements downhole as well as multipoint monitoring at many surface locations including in flowlines, manifolds, and tanks.
Additional presentations covered topics such as new rod connections, electrical submersible pumps in heavy oil production areas such as Brazil and Colombia, polypropylene-lined tubing to reduce wear, and tubingless production utilizing hollow rod technology.
