The use of laurylamine hydrocholoride CH3 (CH2)‎ 11 NH3-Cl for secondary oil recovery

الملخص EN

Lauryl amine hydrochloride CH3 (CH2)11 NH3 – Cl has been chosen from cationic surfactants to produce secondary oil using lab.

Model shown in fig.

(1).

the relationship between interfacial tension and (temperature, salinity and solution concentration) has been studied as shown in fig.

(2, 3, 4) respectively.

The optimum values of these three variables are taken (those values that give the lowest interfacial tension).

Saturation, permeability and porosity are measured in the lab.

The primary oil recovery was displaced by water injection until no more oil can be obtained, then lauryl amine chloride is injected as a secondary oil recovery.

The total oil recovery is 96.6 % or 88.8 % of the residual oil has been recovered by this technique as shown in fig.

(5).

this method was applied in an oil field and it gave approximate values close to that obtained in the lab.
