In this work, phase behavior was analyzed for recombined mixtures of a Brazilian pre-salt crude oil with carbon dioxide and methane. This oil was sampled at stock tank conditions during a well-test, and mixtures with gas were prepared with a gas…
Production allocation refers to the practice of quantifying proportions of extracted commingled hydrocarbons across various contributing sources. In this paper we tested a new geochemical technique of trace element production allocation by analyzing…
This paper presents the design of a polymer flood pilot in a very heterogeneous, sour Heavy Oil reservoir (referred to as HO Reservoir in this paper), which has three times the salinty of sea water with a high mineral content. In addition, the paper…
A systematic study into the origin and potential formation processes of condensates in the Pinghu Slope Belt of the Xihu Depression, East China Sea Basin, was conducted using fluid inclusion analysis, petroleum geochemistry, and rock gold-tube…
The water content data of wellhead crude oil is an important basis for determining the production accounting of oil fields, the adjustment of block unit and the effectiveness of the single well operation, which is related to enterprise cost…
Non-equilibrium phase behavior of hydrocarbons has a great influence on the development of gascondensate and oil and gas condensate deposits, as well as oil deposits after evolution of dissolved gas.The key parameter of mathematical models that take…
Well production in oil fields is a dynamic and complex activity. The patterns and characteristics inherent tothe well, such as pressures and flow rates, are changing based on production time and the fluid composition-A complex multiphase mixture…
