METHOD OF OBTAINING A TREATMENT COMPOSITION FOR IMPROVING THE PRODUCTIVITY OF HYDROCARBON PRODUCING WELLS

摘要

A method of obtaining a treatment composition for treating a hydrocarbon-bearing clastic formation having brine therein to enhance recovery of hydrocarbon from the formation. The method comprises: obtaining a formation information set comprising a temperature value, brine content value, and brine composition data obtained from a geological zone of the hydrocarbon-bearing clastic formation; comparing the formation information set to a compatibility information set to generate a comparison information set, the compatibility information set comprising compatibility information for at least at least one model brine and at least one model composition at at least one model temperature; selecting a treatment composition based, at least in part, on the at least one comparison information set, wherein the treatment composition comprises a second surfactant dissolved in a second solvent; and obtaining the treatment composition for treating the hydrocarbon-bearing clastic formation to enhance recovery of hydrocarbon from the formation.
