Studying the Effect of Calcium Carbonate Scale Deposit on Crude Oil Flow Characteristics
Аннотация
This paper describes detailed study of calcium carbonate scale deposit on crude oil flow lines in the Niger Delta region. The investigation conducted revealed that the crude oil production could come to a half if a major delivery or discharge line, containing a considerable amount of hard effluent or supersaturated produced water, is blocked by precipitated or crystallized inorganic, dissolved or suspended solids component of the formation fluid. Mathematical model was developed to simulate the effect of diameter, radius, velocity distance, time and volume as functional parameters of flow characteristics. The paper contains flowchart for field preliminary identification of scale and of internal pipe diameter drastically reduced by various mineral scale deposit in some flow station terminals of Niger Delta region High deposit of calcium carbonate increases bacteria and fungi concentration as well as reducing crude oil production volume and corrosion in this case was largely attributed to the presence of these species and calcium carbonate scale deposit
