New chemical system delivers benefits

摘要

Three subsea oil production giants are trying to unlock the full potential of the reservoir. Over the past 5 years, the Ondeo Nalco Energy Services Division has partnered with BP Exploration and Shell UK Exploration and Production to test a new chemical delivery technology that should help oil producers achieve longer, uninterrupted oil production. The system, which controls depositions, corrosion and reservoir souring, alms to improve conventional methods of protecting reservoir and production tubing from problems such as scale, corrosion and bacterial growth. The emulsion technology, known as the Access system, increases the effectiveness and longevity of chemical treatments required to prolong the life of well tubulars. Application carries fewer risks than conventional aqueous treatments because the system enables more rapid cleanup of the well and minimizes damage to the near wellbore area. The system has proven effective in difficult subsea environments, horizontal wells and sensitive reservoirs.
