“…After washing steps, the samples are dried in an oven at 65 °C until a constant mass and the porosity and air permeability are then determined. 45,46 The determination of the irreducible water saturation was carried out with reconstituted water prepared in the laboratory. This solution is composed of distilled water containing 8.5% NaCl and 2.5% KCl.…”

The objective of this work is to study the effect of certain factors on oil−water relative permeability curves following a considerable drop in the production of certain oil wells at the Hassi Messaoud field in southern Algeria. In the present study, oil−water relative permeability experiments and irreducible water (S wi ) and residual oil (S or ) saturations have been investigated. The effect of the clay particle content in the samples (such as illite and kaolinite) on oil recovery is investigated. Indeed, other factors, such as injected pressure, wettability alteration, and petrophysical properties, of the reservoir rock interact with each other and, particularly, in the presence of injected Albian water. Results of the waterflooding experiments show that oil recovery (IOP) increases with increasing clay content, namely, kaolinite and illite type; this IOP is clearly higher for plugs containing more kaolinite than illite. The tested samples have water-wetting behavior, showing a decrease in S or and an increase in S wi , and are characterized by a strong presence of clays, 70% kaolinite and 30% illite, with a breakthrough from about 40 to 50%.

Summary In this work, an analysis of production data for determining the damage effect in geothermal wells is reported. Measurements of some Mexican geothermal wells have been analyzed for evaluating the decrease of their productivity under exploitation conditions. As an innovation of the methodology used in this work, the dimensionless well flow parameters (pressure and mass flow rate), and the inflow performance relationship curves of producing wells were determined by using more representative thermodynamic properties of the geothermal fluid (i.e., characterized as a ternary compound system: H2O–CO2–NaCl). Geothermal inflow type‐curves were therefore used for determining the wellbore damage effect. Production measurements of the wells were compiled at different stages of their operative life cycle. From this study, it was found that the wellbore damage effect increases with the exploitation time. These results enable a drop in the fluid flow mechanisms of the wells to be identified. The quantitative knowledge of the wellbore damage effect helped us to define a technical criterion for the decision making of the most appropriate engineering operations to be applied (e.g., cleanings, repairs, stimulations, fracturing, etc.) either to recover or to improve the well productivity.
