Predicting the compatibility of crude oils from different streams can be done by applying models that use the solubility parameter of the oils. The approximate solubility parameter value of a given crude oil can be calculated by observing the asphalt

Three methods to obtain isoprene oligomers were evaluated: chemical degradation of non-vulcanized coagulated natural rubber; chemical degradation of natural rubber latex; and oligomerization of the isoprene monomer. The products were characterized by

Knowledge of the lowest temperature at which a particular petroleum type is still able to flow (pour point) is important for its marketability. High pour point temperatures make transport and refining more difficult and thus can reduce demand and pri

High molar mass paraffins in the crude oil solidify with the reduction of temperature during offshore production, which can reduce production or even block outflow lines. Polymers can be used to inhibit the wax deposition. However, the efficiency of

Crude oils containing large quantities of waxes, and in situations where sudden temperature drops occur, a crystalline network can be formed, generating flow difficulties in production, transfer and offloading lines. Despite the scientific and econom

One of the main problems faced while drilling oil wells is loss of fluid to the rock formation. This loss can be reduced with the use of chemical additives called filtrate controllers, which must be tailored to the specific characteristics of the roc
