Dragon Oil needed to extend the production lifetime for wells with lower than expected natural flow duration. After reviewing multiple options, Dragon Oil chose to implement artificial lift using jet pumps to return the candidate wells to the required production levels. This case study highlights the rationale, implementation, and outcomes from this additional well investment. Candidate wells for jet pump artificial lifting have been drilled from offshore wellhead platform 1 into the crest of the main reservoir production basin. A multiwell hydraulic jet pump system was installed during the spring of 2013.
