Report summaryAs an oil producer, Santa Rosa is now highly mature and in decline. In order to capitalise on the field's significant gas reserves and to minimise the national gas deficit, the field has been developed as a gas producer since 2001. The field is of strategic importance to PDVSA and is key to its plans for increasing gas injection on Eastern basin fields. The Santa Rosa field is located in the Greater Anaco area of the Eastern Venezuela basin, about 10 kilometres to the northeast of the town of Santa Rosa. The field covers an area of 300 square kilometres and contains 45 metres of hydrocarbon sands distributed within a column of 3,000 metres. The sands are of varying thickness and are subdivided into a total of 434 reservoirs. The majority are condensed gas with a leg of light oil. Government regulations requiring that individual deposits be completed and produced individually have led to studies to identify individual hydraulic units (in which sands are in communication).
