Difficulties and challenges met by Vietsovpetro while transporting paraffinic oil by offshore subsea pipelines

Tu Thanh Nghia1, Pham Ba Hien1, Pham Xuan Son1

Tong Canh Son1, Nguyen Hoai Vu1, Ngo Thuong San2 Nguyen Van Minh2, Nguyen Thuc Khang2 1Vietsovpetro2Vietnam Petroleum Association

Summary

Vietsovpetro has developed technologies for recovery, treatment and transportation of paraffi nic crude oil which are suitable to the actual conditions of oil and gas fi elds operated by Vietsovpetro and diff erent from previous tech-nologies. This success was based on Vietsovpetros comprehensive studies of the rheological properties of paraffi nic crude oil produced by Vietsovpetro, and many systematical researches that summed up all of the diffi culties and chal-lenges while transporting paraffi nic oil from Bach Ho and Rong fi elds by off shore undersea pipelines. Based on that, the technologies for recovery, treatment and transportation of paraffi nic crude oil have been established and devel-oped in Vietsovpetro.

Key words: Transportation of paraffi nic crude oil, paraffi n deposition, pour point temperature.

Characteristics of Mesozoic carbonate reservoir in Ham Rong field, Block 106 in Vietnams continental shelf

Le Trung Tam1, Pham Van Tuan2, Ngo Van Hung31Petrovietnam Exploration Production Corporation (PVEP)2University of Mining and Geology3Vietnam Oil and Gas Group

Summary

This paper presents the research results on the characteristics of Mesozoic carbonate reservoir in Ham Rong, Ham Rong Nam and Ham Rong Dong area (Block 106 in the continental shelf of Vietnam) on the basis of integrated analy-sis of seismic and well logging data. By applying various research methods such as petrographic thin section analysis, XRD analysis, scanning electron microscopy (SEM), logging, seismic attributes, and application of artifi cial neural network (ANN) for building porosity model, the authors have conducted depositional environment analysis, rock classifi cation of Mesozoic carbonate, and analysis of secondary diagenesis processes that aff ect the stratigraphic quality and porosity model of the studied area.

Key words: Mesozoic carbonate reservoir, Fusuline fossil, secondary diagenesis, porosity.
