Estimating reservoir pressure and temperature is one of the challenges of geothermal reservoir engineering. A new proxy model has been developed to estimate reservoir pressure and temperature using wellhead pressure, temperature and non-condensable gas (NCG) amount. An exhaustive set of wellhead data covering a range of possible wellhead pressure, temperature and NCG data is used in a calibrated wellbore simulator, which is then used to create a knowledgebase to train an artificial neural network (ANN) model. The developed ANN model tested using numerical simulation model results coupled with a wellbore simulator. It is observed that the ANN model can accurately estimate reservoir pressure and temperature for various production scenarios in liquid phase reservoir.

Integrated 3-D finite element simulation of the Edremit geothermal system Yoğurtçuoğlu, Alp; Karahanoğlu, Nurkan; Department of Geological Engineering (2016) The Edremit Geothermal system consists of a shallow cold aquifer and a hot reservoir layer at depth. A 3-Dimensional Finite element model with 65596 nodes is used to simulate this system by an integrated algorithm in a 3 km by 3 km with 300 meters of depth study area consisting of currently operating geothermal field deep water wells. To determine the permeability values and hydraulic gradient values in the study area, a 2-Dimensional simulation was performed with 27664 nodes for the entire Edremit Basin, a...
A New Isotropic Specimen Preparation Method from Slurry for both Saturated and Unsaturated Triaxial Testing of a Low-Plasticity Silt Ahmadi-Naghadeh, Reza; Toker, Nabi Kartal (ASTM International, 2019-07-01) A new procedure for the preparation of low-plasticity silt specimens that are isotropically reconstituted from slurry is developed for use in both saturated and unsaturated soil testing. Spatial variations of the water content and grain size distribution were examined to confirm the uniformity of the specimens (regarding void radio and segregation). The new preparation method results in a homogeneous specimen, which has a simple stress history. The repeatability of the proposed method in preparing identical...
A Mechanistic Model for Predicting Frictional Pressure Losses for Newtonian Fluids in Concentric Annulus SORGUN, MEHMET; Ozbayoglu, M. E. (Informa UK Limited, 2010-01-01) A mathematical model is introduced estimating the frictional pressure losses of Newtonian fluids flowing through a concentric annulus. A computer code is developed for the proposed model. Also, extensive experiments with water have been conducted at Middle East Technical University, Petroleum and Natural Gas Engineering Department Flow Loop and recorded pressure drop within the test section for various flow rates. The performance of the proposed model is compared with computational fluid dynamics (CFD) soft...
A HEAT-TRANSFER CORRELATION FOR LIQUID-SOLID FLOWS IN HORIZONTAL PIPES OZBELGE, TA; SOMER, TG (Elsevier BV, 1994-08-01) Heat transfer from a solid surface to a fluid-solid suspension in vertical or horizontal transport is of importance in the design of heat-exchangers, driers, fluidized beds, and slurry pipeline reactors. There are fewer studies on heat transfer in liquid-solid flows than on gas-solid flows. In this paper, a correlation for heat transfer to dilute liquid-solid flows in a horizontal pipe is presented. Suspension properties were used to derive the following equation: Nu(s) = 0.202Res0.6Prs0.675(D/d(p))0.092(mu...
A new method for determining the depth of cut using power shovel monitoring Karpuz, Celal; BOZDAG, T (Springer Science and Business Media LLC, 2001-01-01) The method based on the power shovel monitoring is described for determining the depth of cut and the value of power consumption depending on the rock strength and the dipper position in digging operation. The investigations into mining shoves operating at different open-pit mines of Turkish Coal Enterprises were carried out.
