Thermal maturity modelling is widely used in basin modelling to help assess the exploration risk. Of the calibration algorithms available, the Easy%Ro model has gained wide acceptance. In this study, thermal gradients at 70 wells in the Thrace Basin, NW Turkey, were calibrated against vitrinite reflectance (%Ro) using the Easy%Ro model combined with an inverse scheme. The mean squared residual (MSR) was used as a quantitative measure of mismatch between the modelled and measured %Ro. A 90% confidence interval was constructed on the mean of squared residuals to assess uncertainty. The best thermal gradient (i.e. minimum MSR) was obtained from the MSR curve for each well, and an average palaeo-thermal gradient map of the Thrace Basin was therefore created. Calculated thermal gradients were compared to the results of previous studies. A comparison of modelled palaeo-thermal gradients with those measured at the present day showed that the thermal regime of the Thrace Basin has not changed significantly during the basin's history.

Investigation of the thermal gradient history of the thrace basın, nw Turkey, by using a modified easy %ro maturity model
Huvaz, Özkan; Karahanoğlu, Nurkan; Department of Geological Engineering (2005)
Thermal maturity modeling is widely used in basin modeling. Of the available models, Easy%Ro has gained acceptance. Thermal gradients (TG) at seventy wells in the Thrace Basin are calibrated against vitrinite reflectance (%Ro). A 90% confidence interval is used to assess the uncertainty. Best paleo-TG are obtained from the MSR curves. Comparison of the paleo-TG with the actual ones showed that thermal regime of the Thrace Basin did not dramatically change during geologic history. A correlation between geolo...
A stochastic approach in reserve estimation
Kök, Mustafa Verşan (Informa UK Limited, 2006-12-01)
Geostatistics and more especially stochastic modeling of reservoir heterogeneities are being increasingly considered by reservoir analysts and engineers for their potential in generating more accurate reservoir models together with usable measures of spatial uncertainty. Geostatistics provides a probabilistic framework and a toolbox for data analysis with an early integration of information. The uncertainty about the spatial distribution of critical reservoir parameters is modeled and transferred all the wa...
An investigation of polymerflooding in limestone reservoirs with a bottom water zone
Bağcı, Ali Suat; Hodaie, H (Informa UK Limited, 2003-03-01)
The effects of polymers on waterflooding of a limestone reservoir with or without a bottom water zone, as well as the effect of vertical and horizontal production wells on oil recovery, have been investigated in laboratory models. Sixteen core flood displacement tests were conducted to study the effect of relative oil-water layer thickness, polymer slug size, and well configuration in a production port. A qualitative comparison was made to show the difference between waterflooding and polymer-augmented wate...
The role of overstrength on the seismic performance of asymmetric-plan structures
Kaatsız, Kaan; Sucuoğlu, Haluk (Wiley, 2019-04-10)
Uneven distribution of seismic demand in asymmetric-plan structures is a critical concern in earthquake-resistant design. Contemporary seismic design strategies that are based on linear elastic response, single load reduction factor, and uniform ductility demand throughout an asymmetric system generally lead to unsatisfactory performance in terms of realized ductilities and nonuniform damage distribution due to strong torsional coupling associated with asymmetric-plan systems. In many cases, actual nonlinea...
Parametric Study of Carbon Dioxide Sequestration in Deep Saline Aquifers
Basbug, B.; Gumrah, F. (Informa UK Limited, 2009-01-01)
CO2 sequestration in a deep saline aquifer was simulated using a compositional commercial simulator based on a single-well aquifer model, which was developed to analyze the injection and storage process of CO2 under supercritical and gaseous conditions for long periods of time. The influence of controlling parameters including vertical to horizontal permeability ratio, aquifer pressure, injection rate on the isothermal injection, and sequestration processes were investigated and the sensitivity analysis cor...
