Paraffin, Asphaltene and Scale in Crude Oils: Theory, Problems and Solutions
DESCRIPTION
This course discusses the latest results in characterization of paraffin, asphaltene and scales in crude oils. Differential paraffin deposition theory and analysis of the mechanisms of paraffin, asphaltene and scales deposition are included. Field strategies for the production of crude oils with differential paraffin deposition are presented. Special attention is given to the description, construction and interpretation of P-T-ADE envelopes to establish production strategies to produce asphaltenic crude oil and avoid or minimize formation damage thought asphaltene control deposition.
