Reducing Cost of Geothermal and Petroleum Explorations with Invariants

81st EAGE Conference and Exhibition 2019 (2019)

F. Dogru Oya Pamukçu

Summary Satellite-based gravity models have been used by many researchers for crust modelling, co-seismic studies, geoid determination and determining tectonic structures. Usages of Complete Spherical Bouguer gravity anomalies have become more popular due to the its easy gathering. Additionally, invariants of gravity tensors attract great interest in the petroleum and geothermal energy explorations. In this paper, WGM2012 Complete Spherical Bouguer gravity anomalies are used to evaluate the tensors and invariants of the Eastern part of Turkey. The area contains geothermal and petroleum fields but reaching petroleum has some problems in terms of tectonic collisions of the Arabian and Anatolian plate. In this paper, I1 and I2 invariants of gravity tensors are evaluated to determine the location of geothermal and petroleum fields. Due to the results of invariants are related to density variations of study area and the anomalies show the effect of the different sources on the underground. Firstly examining invariants for large areas, reducing cost of explorations via decreasing study area.

Interpretation of the magnetic anomalies over the Mid-Atlantic Ocean Ridge using Swarm-A satellite

Geofizika (2022)

İlkin Özsöz Oya Pamukçu

The procedures and interpretation of the magnetic data measured over the Mid-Atlantic Ocean Ridge by Swarm-A satellite is discussed in this paper. The data processing procedure has four phases after the data format conversion. The first phase is the selecting data whose Kp index is lower than 1. Secondly, the main magnetic field should be subtracted from the measured data for example through the IGRF model. This step is followed by removing trend, related to the satellite trajectory. The final step is eliminating the dipole nature of the magnetic field via Reduction to the Pole (RTP). Nonetheless, the RTP process might cause misinterpretation over the large study area and lower latitudes. Therefore, the amplitude of the analytic signal (AS) is used as an alternative to the RTP. The qualitative interpretation of the magnetic anomaly is conducted via AS anomaly, bathymetry, heat flow and tectonic map. Quantitatively correlation coefficients of bathymetry and heat flow with respect to AS are interpreted.

A multi-approach geophysical estimation of soil dynamic properties in settlements: a case study in Güzelbahce-İzmir (Western Anatolia)

Journal of Geophysics and Engineering (2013)

Mustafa Akgün Tolga Gönenç Aykut Tunçel Oya Pamukçu

An earthquake is a natural disaster which cannot be predicted beforehand. The economic losses and casualties induced by earthquakes badly influence human life. In order to reduce these negative effects, buildings and structures should be designed to be earthquake resistant. In the design stage of earthquake-resistant structures, models of soil under dynamic conditions are used. The parameters that are required to account for soil dynamic models are shear wave velocity (Vs) values, stiffness, thickness, the number of layers, attenuation, rigidity and the depth to bedrock. These parameters are used to calculate an empirical transfer function, the bearing capacity of the soil and liquefaction. Within this context, these soil dynamic parameters should be obtained with the help of geophysical methods in situ, in the İzmir-Güzelbahçe region and its surrounds. The İzmir-Güzelbahçe region and its surrounds are located at the intersection point of two major faults (the İzmir fault and the Seferihisar fault). For this reason, soil dynamic parameters are variable in the lateral and vertical directions. These changes affect the soil Vs profiles. To identify the shear wave velocity (Vs) profile, common mid-point cross-correlation analysis of multi-channel surface-wave data (CMPCC MASW method), microtremor and microgravity methods can be used in common. As a result, when these three methods were evaluated together, it was concluded that the aforementioned region shows sudden lateral structure changes. Relying on these changes, the dynamic analyses that would be carried out to determine soil behavior at a possible earthquake site should be taken into consideration.

Analysis of the Stress Distribution of North Anatolian Fault Zone for the Part Between Amasya-Tokat Cities

Bulletin Of The Mineral Research and Exploration (2021)

Ayça Çırmık Ufuk Aydın Oya Pamukçu Fikret Doğru

Tectonic forces formed in the continental crust, cause permanent changes in stress, compression and deformation. The amplitudes of earthquake waves vary with the stress / strain distribution in the crust. In this study, the change of stress / strain and regional absorption coefficient, which is effective in tectonic forces caused by elastic deformation energy accumulating in the brittle crust over time, was investigated. The study area is the middle part of the North Anatolian Fault Zone and the area formed by Ezinepazarı fault zone and Merzifon fault zone. In this area, Coulomb stress analysis was carried out by using the focal mechanism solution values of the earthquake that occurred in Yoldere - Erbaa, Tokat on October 9, 2015 (ML = 5.1). In order to examine the deformation caused by this earthquake in and around the study area, Global Navigation Satellite System (GNSS) data were evaluated and the velocities of these stations were calculated using GNSS data of these stations for the years 2013 - 2014 - 2015 - 2016. Also, regional absorption coefficients were determined by using earthquake data. As a result, Coulomb stress analysis results, velocity values distribution obtained from GNSS data and absorption findings obtained from seismological study were evaluated together.
