This paper focuses on analysing pressure behaviours and rate transient of multi-porous media formations such as carbonate reservoirs depleted by horizontal wells. Several analytical models (pressure transient and rate transient) have been developed using the well-known dual-porosity models for naturally fractured formations and modified for triple-media formations considering the existence of hydraulic fractures. The solutions of these models demonstrate different flow regimes corresponding to different production times. The study has pointed out that the impact of multi-media on pressure behaviours can be observed at intermediate production time shortly after the production pulse has reached the lower and upper boundaries. While the flow regimes created by multi-media are characterised by two parallel lines on pressure derivative curves. These two lines can be used to identify the type of natural fracture system. It has been found that type-1 NFR is characterised by perfectly parallel lines wherein the vertical distance between these two lines equals the horizontal distance. The study emphasised that rate transient behaviour may not exhibit same flow regimes that could be developed by pressure transient. [Received: July 15, 2016; Accepted: February 1, 2018]

Implementation of horizontal well CBM/ECBM technology and the assessment of effective CO2 storage capacity in a Scottish coalfield Sınayuç, Çağlar; Imrie, Claire E.; Syed, S. Amer; Korre, Anna; Durucan, Sevket (Elsevier BV, 2011-01-01) In this study the theoretical and effective methane recovery and CO2 storage potential of four coal seams within a well characterised section of a CBM license in Scotland are estimated, considering different horizontal well patterns, the effect of permeability heterogeneity and the composition of the injected fluid. The study concerns the Airth area of the Clackmannan coalfield in the Scottish Midland Valley. The effort on building the static earth model and the history match results of the pre-existing ver...
Pseudo-steady state inflow performance relationship of reservoirs undergoing multiphase flow and different wellbore conditions Al-Rbeawi, Salam (Elsevier BV, 2019-08-01) This paper introduces an integrated approach for the inflow performance relationship of reservoirs that undergo multiphase flow conditions and drained by vertical wells with different wellbore conditions. The main objective is eliminating uncertainties that govern predicting reservoir performance by assuming single phase flow in the porous media. The proposed approach includes developing several models for multiphase flow conditions using PVT data and relative permeability curves. These models are assembled...
Assessment of CO2 Storage Potential in Turkey, Modeling and a Prefeasibility Study for Injection into an Oil Field Okandan, Ender; Karakeçe, Yıldız; Cetin, Hayati; Topkaya, Ilhan; Parlaktuna, Mahmut; Akın, Serhat; Bülbül, Sevtaç; Dalha, Chantsalma; Anbar, Sultan; Cetinkaya, Ceyda; Ermis, Ismail; Yilmaz, Mustafa; Ustun, Volkan; Yapan, Kadri; Erten, A. Tayfun; Demiralin, Yasemin; Akalan, Ergun (2010-09-23) The large amount of CO2 that can be mitigated by geologic storage had gained interest during the last 15 years. Acceptance of CCS under CDM is still under discussion(IEA, 2008) however there are several pilot or field scale projects and monitoring surveys that are underway which will make the technology better known and resolve the risks involved. This study involves assessment of possible geologic sites for CO2 storage and calculation of CO2 emissions from thermal power plants with capacities > 500 MWe, ce...
Assessment of fracture connectivity and potential for CO2 migration through the reservoir and lower caprock at the In Salah storage site Smith, James; Durucan, Sevket; Korre, Anna; Shi, Ji-Quan; Sınayuç, Çağlar (Elsevier BV, 2011-01-01) Fractures are thought to strongly affect the flow of CO2 at the In Salah storage site. In the work presented here, fracture networks at In Salah are characterised and modelled to assess percolation. Available fracture data is considered in the context of general characteristics of other fracture networks and this data is then used to model potential realisations of fracture networks within the In Salah reservoir and lower caprock. Horizontal percolation of fracture networks is highly dependent on fracture l...
Thermo-oxidative characterization and kinetics of tar sands Kök, Mustafa Verşan (Elsevier BV, 2011-08-01) In this research, non-isothermal kinetics and thermal analysis of Gercus tar sand sample is studied by DSC (differential scanning calorimeter) and TG/DTG (thermogravimetry). Experiments were performed using three different mesh size (20-35, 35-50 and >50) of sample. Differential scanning calorimeter (DSC) curves revealed three reaction regions in the temperature range of 20-600 degrees C. On the other hand, thermogravimetry (TG/DTG) curves of tar sand samples at different particle sizes demonstrated three s...
