This research aims to investigate possible ultimate recovery from the largest oil reserve (Bati Raman) in Turkey using a new method called mining-assisted heavy oil production (MAHOP) where declines (tunnels) are excavated from the surface to the reservoir. A series of excavations (galleries) continue along the bottom of the reservoir and proceed along the reservoir's bottom. Fan-shaped steam injection holes that are drilled in the reservoir from the top and sides of the galleries are then used to inject steam similar to conventional steam-assisted gravity drainage (SAGD). A scaled experimental model and a numerical model have been designed and developed to assess the advantages and disadvantages of the proposed method. MAHOP experiments conducted at different wettability conditions showed that ultimate oil recovery varies between 49.56% and 71.73%. These promising results are then verified using a numerical model. It is argued that the temperature increase may alter the wettability of oil-wet rock to more water-wet, which contributes to incremental oil recovery. The conceptual economic study of the MAHOP recovery results show that the process can be economical in terms of both initial investment and operating costs. Thus, MAHOP is strongly recommended for the exploitation of the Bati Raman field.

Mining-Assisted Heavy Oil Production (MAHOP) Canbolat, Serhat; Öztürk, Hasan; Akın, Serhat (2020-12-08) This research aims to investigate and compare the ultimate recovery from the largest oil reserve in Turkey (1.85 billion barrels) using a new method called mining-assisted heavy oil production (MAHOP) with conventional SAGD. Tunnels will be excavated from the surface to the reservoir. Fan-shaped up holes will then be drilled in the reservoir from the tunnels.Heavy oil production through these tunnels will be explored using SAGD method. Several numerical models have been designed using CMG’s STARS simulator....
Exploitation of Bati Raman field using advanced thermal methods: MAHOP VS. CSHP Canbolat, Serhat; Öztürk, Hasan; Akın, Serhat (2021-01-01) The aim of this work is to examine and estimate the ultimate recovery from Turkey's largest oil reserve (1.85 billion barrels) utilizing a new approach called mining-assisted heavy oil production (MAHOP) and conventional steam injection horizontal production (CSHP) method. In MAHOP, declines (tunnels) are excavated from the surface to the reservoir and proceed along the reservoir's bottom. Fan-shaped steam injection holes are drilled from the upper and lower sides of the reservoir with conventional steam-as...
Evaluation and optimization of microbial oil production using synthetic sugars Gürel, Nermin; Çekmecelioğlu, Deniz; Department of Food Engineering (2019) Oleaginous microorganisms produce microbial oil that can be a solution to sustainable oil production. Lipomyces starkeyi DSM70295 and Rhodosporidium toruloides DSM4444 yeasts were chosen to produce microbial oil in this study. Synthetic sugars, glucose, galactose,xylose, fructose and 1:1(w/w) combinations of sugars with glucose were used in fermentation medium. Nitrogen is an important criterion for yeast growth and lipid accumulation. To test effects of nitrogen on yeast growth and lipid production, C/N ra...
Testing Amenability of Oil Shales to Gravitational Cleaning Altun, Naci Emre (2016-10-23) This study aims at investigating the possibility of cleaning of oil shales by gravitational methods. Laboratory scale Dense Medium Separation (DMS) tests were applied on Himmetoglu oil shale from Bolu, Türkiye. DMS tests were conducted at a separation specific gravity range of 1.10 to 1.80 with 0.1 increments on size fractionated oil shale samples of -30+18, -18+10, -10+0.5 and -0.5 mm. Results showed that the extent of ash rejection and improvements in calorific values increased with increasing fineness an...
Application of predictive Enhanced Oil Recovery models on a very heavy oil field Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2001-12-01) In this study, several predictive enhanced oil recovery (EOR) techniques are used to evaluate potential thermal oil recovery techniques that could be applied on a very heavy oil (10-12°API) field located in Southeast Turkey. Two of the EOR techniques were found to be applicable after the screening process: in situ combustion and steam injection. Sensitivity of the processes to several operating parameters, such as steam injection rate, air injection rate, and steam quality, were established. It was observed...
