Recovery calculations of oil fields using predictive models

Oil reservoirs are often candidates for secondary and tertiary recovery processes. These recovery processes are needed to be screened for priority ranking due to budget, manpower, development, capabilities and permitting limitations. Sensitivity studies also need to be made in order to determine the effects of various operating strategies on project performance and economic feasibility. In this research, the application of different enhanced oil recovery methods on five heavy oil fields with different reservoir and fluid properties were investigated. Results considering several fluid properties and reservoir characteristics showed that different recovery methods are feasible for each heavy oil field.

Modeling of underground gas storage in a depleted gas field
Gumrah, F; Izgec, O; Gokcesu, U; Bağcı, Ali Suat (Informa UK Limited, 2005-07-15)
It is possible to predict the behavior of fluids in permeable and porous medium under different operating conditions by using reservoir models. Since geological data and reservoir properties can be defined most accurately by reservoir models, it has been accepted as a reliable prediction tool among reservoir engineers. In this study, a gas reservoir has been modeled with IMEX Module of CMG Reservoir Simulator. Rock properties, gas composition and certain production data were entered to the model as input da...
Spontaneous imbibition in low permeability carbonates
Hatiboglu, CU; Karaaslan, U; Akın, Serhat (Informa UK Limited, 2005-07-01)
Spontaneous imbibition is important in oil recovery from fractured and low permeability tight gas reservoirs. Gas-water spontaneous imbibition experiments were conducted using low permeability heterogeneous limestone core plugs. The interfacial tension was changed by adding differing amounts of alcohol to water. It was observed that the true residual saturation of gas is very small for all cases. A much larger pseudo-residual saturation was achieved early in the imbibition stage but gas continued to be prod...
Performance prediction of underground gas storage in salt caverns
Bagci, A. Suat; Ozturk, E. (Informa UK Limited, 2007-01-01)
Underground gas storage is a common activity in countries with major transport and distribution gas pipeline infrastructures, which allows to efficiently resolve demand seasonality problems. Subsurface caverns in salt formations are being increasingly used for storage of natural gas. In this study, a real salt cavern having the potential for being an underground gas storage unit was evaluated. A model of the salt cavern was constructed within the gas simulator established for the purposes of this study. The...
Empirical correlations for estimating filtrate volume of water based drilling fluids
Ozbayoglu, Evren; Gunes, Cagri; Apak, Esat C.; Kök, Mustafa Verşan; Iscan, A. Gurkan (Informa UK Limited, 2005-03-01)
Standard American Petroleum Institute (API) filter press is generally used for identifying the filtrate volume of drilling fluids and works only at very low pressures. In fact, during a drilling operation, at downhole conditions, the pressures encountered are significantly higher than what is used during standard API filter press tests. A relationship between the well-known fluid properties and the filtrate volume test is developed. In this study, experiments have been conducted for different water-clay mix...
Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells
Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01)
In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are,...
