Improved Model for Predicting Formation Damage Induced by Oilfield Scale
Fadairo Adesina, and Omole O.,
The process of formation damage due to oilfield scale precipitation and accumulation has been quantitatively modeled based on existing thermodynamics and deposition kinetic model. A variety of models on formation damage due to solid precipitation in porous media during water flooding have been reported in the literatures. Early models were based on chemical reaction involving dissolution/precip...
A Modified Model for Predicting Permeability Damage due to Oilfield Scale Deposition
Fadairo, A. S. A., Omole, O. and Falode, O.
Scaling is a major problem in water flooding caused by the mixing of incompatible injected and formation waters. The phenomenon results in precipitation and accumulation of oilfield scale around the well bore after water breakthrough at reduced reservoir pressure. This result in formation damage, which may influence reservoir well bore performance and success of water flood project. This articl...
Effect of Oilfield Scale on Productivity Index
Fadairo A.S. Adesina, Ako C.T., Omole Olusegun and Falode Olugbenga
The precipitation and deposition of scale pose serious injectivity and productivity problems. Several models have been developed for predicting oilfield scales formation and their effect on deliverability of the reservoir to aid in planning appropriate injection water programme. In this study an analytical model has been developed for predicting productivity index of reservoir with incidence of...

Predictive Tool for Bottom-hole Pressure in Multiphase Flowing Wells
Adekomaya Olufemi1, Fadairo A.S. Adesina2, Falode Olugbenga3
The analytical model for predicting the pressure at any point in a flow string is essential in determining optimum production string dimension and in the design of gas-lift installations. This information is also invaluable in predicting bottom-hole pressure in flowing wells.
A variety of model on bottom-hole pressure in flowing wells have been reported in the literatures. Most of the early mo...
Oilfield Scale Induced Permeability Damage Management during Water Flooding
Fadairo A.S, Falode O. and Aderemi S
The precipitation, accumulation and disposition process of oilfield sulphate scales is a major ongoing flow assurance problem in hydrocarbon production. This pose serious injectivity and productivity problems in a water flooded reservoirs.
Several works and software packages such as multi-scale 6.0 and scalechem have been developed for predicting scaling tendency and average scales precipitati...
Effect of Drilling Cuttings Transport on Pressure Drop in a Flowing Well
Fadairo A.S, Adekomaya and Falode
Cuttings transport has a major impact on the economics of the drilling process. It is one of the major factors affecting cost, time and quality of drilling wells. In spite of the many technological advances that have attempted to prevent the cuttings transport along the fluid, one significant challenge remains predicting the effect of cutting transport on pressure drop. Many interdependent vari...
Effect of Oilfield Scale Deposition on Mobility Ratio
Fadairo A.S, Omole and Falode
Scaling phenomenon is a major problem in water flooding where injected and formation waters are incompatible and their mixing causing salt precipitation. The phenomenon results in precipitation and accumulation of oilfield scale around the well bore after the water breakthrough at reduced reservoir pressure. The effect results in formation damage which may influence reservoir performance, well...
Global Solar Radiation Annual Profile, Causes and Seasonal Effects, at Ilorin Nigeria
+*E.B. Babatunde, C.O. Akoshile++, O.A. Falaiye++, T.B. Ajibola ++
The data of short-wave global (total) solar radiation of 4 years (1995-1998) at Ilorin
(8˚ 34′ N, 4˚ 34′ E), Nigeria was used to study the characteristics behavior of SW- global solar radiation in the tropics. To do this its weekly average was plotted and analyzed with respect to the atmospheric constituents responsible for the behavior. On the profile obtained, two “Wells” of unequal size and...
SOME OPTICAL PROPERTIES OF FeCuS THIN FILM APPLICABLE IN SPECTRAL SELECTIVITY APPOCATION IN SOLAR ENERGY.
+E.B. Babatunde and C.C. Uhuegbu
Thin films of Iron Cupper Sulphide (FeCuS) of concentrations 1.66OM, 1.574M and 1.566M respectively were deposited on glass substrates. The thickness of the films deposited ranged from 1.03 to 87.3 x 10-2 µm. Solution growth technique was used in growing the films and they were characterized by measuring their absorbance (A), transmittance (T) and reflectance (R) using PYE-UNICOUV – 2101 PC Spe...
