Wax precipitation and deposition is one of the most important flow assurance problems in production and transportation of crude oil. A thermodynamic and experimental study is proposed for determination of wax deposition and study of its effect on design and operation of waxy crude oil production systems by predicting the wax appearance temperature (WAT) and amount of wax formed under different conditions...
This paper is an extension of previous work [1] and describe a two — dimensional (2-D) mathematical model, developed to simulate the heavy oil recovery process through the use of Heat Assisted WAG with Chemical Additives to reduce viscous fingering and gas override occurrence, which limits the efficiency of the WAG process. In this study we present a 2-D compositional mathematical model formulation...
A procedure is developed for the design and analysis of single pulse tests. A new definition is adopted for the pressure response amplitude that eliminates the effect of pressure trend. The method is applicable for homogeneous reservoirs with negligible well bore storage and skin at both wells. The test may be performed in an interactive way. Analytical equations are derived that explicitly relate...
