Abstract :
South Sudan Petroleum industry is fairly
mature, however; updates about the status of the industry
remains limited, the literature has provided little on some
of the aspects of the industry related to production and
petroleum reserves, this study aims to evaluate petroleum
production performance and remaining reserves in Dar
Petroleum Operating Company (DPOC) oilfields in block
3 & 7; examined over a period of ten years; starting from
2011 to 2021, this is expected to shed some light on the
subject; and provide recommendations for further
research. Method applied; is the collection of secondary
data related to production, reserves and information;
necessary to support the analysis; sourced from Ministry
of Petroleum depository; and from the Joint Operating
Company , which was used in quantitative analysis; and
presentation afterwards, it was found that the production
profile and forecast could only be improved by
introducing oil enhancement technologies; to improve
Recovery Factor (RF) from about 23% to around 33%;
which could make up approximately one third of the
Discovered Petroleum Initially in Place (PIIP) as per the
best industry practices. And that; exerting more efforts on
exploration in the areas not properly covered earlier;
could replenish the reserves in addition to annual
petroleum resources review that has achieved some
addition recoverable volume of 81.72 MMstb. Over the
years covered by the study scope. The limitation of the
research was the lack of data about of reasons related to
quick decline of production after the resumption and
reinstatement of production in April 2013 connected to
the sudden decline in production after 2013 resumption.
