Spontaneous Imbibition Test (SIT) is regarded as an important mechanism of oil
recovery by water-flood, particularly in heterogeneous or fractured reservoirs where direct
displacement of oil by water is usually poor. In this paper a new chemical technology (i.e.
Gaberoun Water Lake Injection (GWLI)) has been discovered. It has several advantages which
are relatively cheap and reliable. It potentially would have a wide range of applications in brine
injection such as altering the rock wettability and responsible for increased ultimate recovery.
Two stages of GWLI were discussed with changing pH and salinity. The first stage was used
the core samples from carbonate and sandstone, which aged in oil for long time period. The
second stage was used the core samples, which aged in oil for short time period. SIT was
performed at 27, 30, 40, 50, 60 and 70o
C with sandstone and carbonate rock with different
aging time. The result showed that the oil recovery was decreased with a decrease in pH values
and increased with a decrease salinity. However, the oil recovery in the long aging process was
low comparing to the short aging process. The findings in this research that GWLI can be used
for oil recovery processes
