The layers lithology traversed by Abouabou drilling was studied using successively 32 samples to a depth of about 240 m. The log established indicates a high level of clay about 63 m, the bottom to the surface. This level is followed by alternating average levels (about 26 m) of sandy clays and sands rich in limestone, with a thickness of 72 m. This assembly is surmounted by average to low levels sandy (40 to 09 m), with calcareous intercalation to the surface. These sands alternate with clay banks of 16 to 10 m. the grain size analyses show essentially coarse to very coarse sands. They have generally bad standings with a strong asymmetry to the fines. Although their characteristics argue for a reduction in their water holding capacity, these sandy levels are still favorable hydrogeological tanks.

Sampling of water from the drilling Abouabou was used to measure the following physico-chemical parameters such as pH, electric conductivity, temperature, turbidity, content of silica, chlorides, aluminum, zinc, magnesium, manganese, copper, ammonium, sulfates, nitrates, nitrites, phosphates and fluorides.
Drilling Abouabou aims to increase water supply capacity of the city of Abidjan and its surroundings. Analysis of physical parameters indicates a neutral pH average of 6.8 ± 0.16 units and an average temperature of 28.83 ± 0.7 ° C. The water is highly mineralized and low in suspended solids with a conductivity average of 2990.83 ± 31.55 μS.cm-1 and an average turbidity 0.862 ± 0.91 NTU. The chemical analyzes, in turn, reveal a significant salinity making the water unsuitable for human consumption without pretreatment. A strong correlation is shown between the contents of chlorides and the physicochemical parameters such as temperature, pH, turbidity, content of iron and manganese. This shows that the drilling of water quality is mainly governed by the chloride contents. The geographical location of the structure near the Atlantic Ocean, deep character and a captive of the web (Continental Terminal) and the absence of solid salts (evaporites) in the formations traversed by drilling suggest two mechanisms either a seawater intrusion, a salinity heritage.
