The shallow marine lithofacies of Kuzgun formation represented by porous reservoir facies are predominantly represented by the sandstones of Middle-Upper Miocene age. On the basis of texture and mineralogy, the sandstone formation may be classified into three lithological units as a lithofacies-1, -2, -3. The impervious lithofacies-1 (non-reservoir) sandstone formation is represented by alternating layers of mudstone/sandstone exhibiting bioturbation characteristics. The lithofacies-2 and lithofacies-3 units constitute the main reservoir facies in the sandstones of Kuzgun formation. Their microporosity is associated mostly with clay minerals. Approximately one-half of the outcrop sand samples has excellent reservoir potential based upon petrographic, scanning electron microscopy-energy dispersive spectrometry, porosity, permeability and capillary pressure analysis. Sections of the reservoir containing more poorly sorted, and with smaller grain size and grain coating and pore filling authigenic clays, have experienced less exposure to pore-fluid flow and thus less effective porosity and permeability development has occurred. These differences have led to variations in reservoir characteristics such as porosity, permeability, and pore throat.

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,...
Polymer gel conformance on oil recovery in fractured medium: Visualization and verification
Canbolat, Serhat; Parlaktuna, Mahmut (Elsevier BV, 2019-11-01)
Due to complexity and heterogeneity of the geological patterns of fractured reservoirs recovery estimations are considered to be extremely challenging. These fractures form complicated paths for reservoir characterization and fluid movement that ultimately impacts production performance and recovery.
Multiphase-flow properties of fractured porous media
Rangel-German, Edgar; Akın, Serhat; Castanier, Louis (Elsevier BV, 2006-05-16)
Water-air imbibition and oil-water drainage displacements were conducted using a laboratory flow apparatus in fractured sandstone systems. During the experiments, porosity and saturation were measured along the core using a Computerized Tomography (CT) scanner. 3-D saturation images were reconstructed to observe matrix-fracture interactions. Differences in fluid saturations and relative permeabilities caused by changes of fracture width have also been analyzed. In the case of water-air imbibition, narrower ...
Creep behaviour investigation of a thin spray-on liner
Güner, Doğukan; Öztürk, Hasan (Elsevier BV, 2018-08-01)
Thin spray-on liner (TSL) is a fast-setting multi component polymeric material applied on a rock surface with a thickness of 2-5 mm. TSLs are primarily used as an areal support element in a support system that also incorporates rock bolts. Different laboratory and field tests were performed to understand the support performance of the TSL for underground design. The research described in this paper presents laboratory studies of the tensile creep behaviour of a cement based TSL for the first time in the lit...
Geotechnical rock-mass evaluation of the Anamur dam site, Turkey
Ozsan, A; Karpuz, Celal (Elsevier BV, 1996-03-01)
This paper describes a feasibility-level geotechnical evaluation carried out at Anamur dam site, in terms of stability analysis of dam foundation, excavation slopes and a diversion tunnel. The proposed Anamur dam will be built across the Anamur river on the Alanya metamorphic series which consists of phyllite, schist and slate units at the site. Geotechnical investigations included drilling for core, pumping tests, sampling for laboratory testing, and a detailed discontinuity survey.
