Guide to World Crudes: Total updates assay for Congolese N'Kossa

Operated by Total Exploration & Production Congo, the 30,000-tonne N’Kossa floating production unit (FPU) sits in 170 m of water and is linked to two drilling platforms 3,200 m apart. Alongside production equipment and utilities, the FPU also hosts living quarters for 160 people and installations for water and natural gas injection. Photo from Setec […]

Study improves performance of TEG dehydration unit at Saudi complex

In early 2017, Saudi Aramco undertook a study to improve dewpoint control performance of gas dehydration units at its 1.2-million b/d Khurais Central Processing Facility (KhCPF) in Saudi Arabia as part of the company’s ongoing program to enhance efficiency across operations. Source: News

CNPC studies Orinoco foamy oil flow, horizontal well spacing

CNPC researched optimal horizontal well spacing and best production practices in Venezuela’s Orinoco belt, which produces heavy oil known as foamy oil. This oil is characterized by high viscosity, a low gas-to-oil ratio during production, and a slow production decline rate compared with conventional heavy oil. Source: News

Subsidence modeling for fluid reservoirs aids hazard mitigation

Subsidence prediction in fluid reservoirs is more difficult than in coal, salt, or ore deposits. Reservoir geometry, physical-mechanical rock mass parameters, and pressure distribution have more uncertainty in oil and gas reservoirs, resulting in a predicted subsidence range rather than a precise subsidence map.

Greece offers new offshore exploration opportunities

Western Greece is characterized mainly by carbonate rocks and this mineralogical composition reduces the ability to clearly image deep structures even more when they are covered by salt strata. Source: News
