Article
Full-text available
Developing a geological model is the first and a very important step during the reservoir simulation and modeling process. The geological model usually represents our best interpretation of the reservoir characteristics that extends beyond the well where we have actual measurements (logs, core, well test, etc.). The only real measurement with a lar...

Full-text available
Waterflooding is a significantly important process in the life of an oil field to sweep previously unrecovered oil between injection and production wells and maintain reservoir pressure at levels above the bubble-point pressure to prevent gas evolution from the oil phase. This is a critical reservoir management practice for optimum recovery from oi...
Article
Characterization of a tight-gas sand formation using data from horizontal wells at isolated locations is challenging due to the inherent heterogeneity and very low permeability characteristics of this class of resources. Furthermore, characterizing the uncontrollable hydraulic-fracture properties along the horizontal wellbore requires financially d...
Article
Full-text available
An artificial-intelligence based decision-making protocol is developed for tight gas sands to identify re-fracturing wells and used in case studies. The methodology is based on fuzzy logic to deal with imprecision and subjectivity through mathematical representations of linguistic vagueness, and is a computing system based on the concepts of fuzzy...
Article
This paper presents several analytical models for the pressure distribution in hydraulically fractured reservoirs depleted by horizontal wells with the aid of the cyclic CO2 injection. The objective is to eliminate the uncertainties in predicting reservoir performance after the enhancement by CO2 injection and develop accurate tools for designing t...
Article
Full-text available
Steam-assisted gravity drainage (SAGD) is an effective enhanced oil recovery method for heavy oil reservoirs. The addition of certain amounts of noncondensable gases (NCG) may reduce the steam consumption, yet this requires new design-related decisions to be made. In this study, we aimed to develop a machine-learning-based forecasting model that ca...
Conference Paper
Carbon capture and sequestration (CCS) will generate an industry comparable to, if not greater than, the existing oil and gas sector. Carbon capture and sequestration is the capture of carbon-dioxide from refineries, industrial facilities, and major point sources such as power plants and storing it in subsurface formations. Subsurface formations li...

A sustainable energy future for Turkey depends on a balanced low-carbon energy mix with continued access to geothermal resources since they are abundant, domestic, renewable and able to supply base load and high energy security. Over 30 years of utilization of hydrothermal systems enabled Turkey to break into the 1 GW Geothermal Country Club as of...

Dikili-Izmir Region (Western Turkey) has been an active area of development for the utilization of geothermal resources. In this study, we aim to quantify the untapped resource-potential in this region for both direct and indirect utilization purposes. After collecting geological data from the literature, probabilistic heat-in-place calculations ar...
Conference Paper
Single-well cyclic gas injection (cyclic pressure pulsing) is an enhanced oil recovery (EOR) method that includes injecting different types of gases that soaks into formation. In hydraulically-fractured wells, surface area of fracture can help the gas-diffusion process to be more effective. After the injected gas penetrates into the rock matrix, in...
Article
Single-well application of cyclic gas injection is a promising enhanced oil recovery method especially in fractured and depleted reservoirs. It was previously shown that presence of hydraulic/natural fractures would increase the effectiveness of this method because of the surface area of fractures that supports gas diffusion into the rock matrix. I...
Article
This paper focuses on studying pressure behavior, flow regimes, and productivity index of oil and gas reservoirs depleted by horizontal wells with a fishbone type completion technology. The main objective is introducing an integrated approach for the favorable configuration and distribution of multilateral horizontal wells extending in porous media...
Article
Full-text available
Capacitance/resistance modeling (CRM) is an empirical waterflood modeling technique based on the signal correlations between injection rates and gross production rates. CRM can satisfactorily estimate the gross (liquid) production rate. The oil-production-rate forecast is based on fitting the empirical oil fractional-flow model, the Leverett (1941)...
Conference Paper

Computationally efficient screening and forecasting tools can offer faster decision-making and value- creation opportunities for enhanced oil recovery (EOR) operations without requiring a high-fidelity reservoir model. In this paper, we present a data-driven modeling approach utilizing numerical models and neural networks (ANN) to screen EOR method...

For Turkey, one sustainable way to increase the clean energy share in the power generation can be the utilization of geothermal resources. This study aims to investigate the potential of hydrothermal system in Dikili-İzmir to generate power. Accessible resource base and recoverable heat energy are calculated by employing a probabilistic approach -...
Article
Tight-gas sand reservoirs are considered to be one of the major unconventional resources. Due to the strong heterogeneity and very low permeability of the formation, and the complexity of well trajectories with multiple hydraulic fractures; there are challenges associated with performance forecasting and optimum exploitation of these resources usin...
Conference Paper
Full-text available
Abundant geothermal springs occur in the Aegean Region of Turkey. These are all associated with two important phenomena: 1. Rough topography causing hydrostatic pressure; and 2. Intersecting fracture planes which provide pathways for water to seep down and flow back to the surface upon getting heated. Deep seated steeply dipping fractures which pro...

Full-text available
Cyclic pressure pulsing with nitrogen is studied for hydraulically fractured wells in depleted reservoirs. A compositional simulation model is constructed to represent the hydraulic fractures through local-grid refinement. The process is analyzed from both operational and reservoir/hydraulic-fracture perspectives. Key sensitivity parameters for the...
Conference Paper
Full-text available
Closed-loop reservoir management requires representative models that can be updated quickly. Such kind of models that can be used for characterization of reservoir connectivity would greatly contribute to decisions in waterflooding operations. In heterogeneous reservoirs that are characterized with thief-zones/fractures or flow-barriers, that may e...

An efficient and rapid workflow is presented to estimate the recovery performance of an existing vertical-well, pattern-based waterflood recovery design using knowledge management and reservoir engineering in a collaborative manner. The knowledge management tool is used to gather production data and calculate pattern-based recoveries and injection...

Full-text available
Estimating future performance of waterflooded reservoirs is a challenging reservoir engineering problem in complex reservoirs that are poorly defined. Flow simulation models characterized by limited spatial data of a key heterogeneity do not always represent the reservoir dynamics for water movement. In this paper, an efficient and rapid workflow i...

Economic success of an IOR project primarily depends on the effectiveness of the selected method in the reservoir of interest and the way it is deployed. Due to the heavy computational work required for a large number of simulations, it is rather an arduous task to determine optimum design schemes for a given project. Proxy models that mimic reserv...

Gas cyclic-pressure pulsing is an effective improved-oil-recovery (IOR) method in naturally fractured reservoirs. A limited number of studies concerning this method in the literature focus on specific reservoirs, yet the optimum operating conditions have not been broadly investigated. In this study, we present a detailed parametric study of the pro...
