Volume 9, Issue 4 , Autumn 2020, , Pages 85-92

http://dx.doi.org/10.22050/ijogst.2020.234641.1552

Abstract
  Seismic well tying is a crucial part of the interpretation phase in exploration seismology. Tying wells usually involves forward modeling a synthetic seismogram from sonic and density logs and then matching the obtained synthetic seismogram to the seismic reflection data. A huge amount of time is required ...  Read More

Volume 9, Issue 3 , Summer 2020, , Pages 1-10

http://dx.doi.org/10.22050/ijogst.2020.221306.1538

Abstract
  The organic geochemical characterization of crude oil samples from the oil fields of the Niger delta was carried out using gas chromatography–-mass spectrometry (GC–-MS) to genetically characterize the oil samples in terms of their biomarker composition. Geochemical characteristics such as ...  Read More

Volume 7, Issue 4 , Autumn 2018, , Pages 1-12

http://dx.doi.org/10.22050/ijogst.2018.101878.1416

Abstract
  Seismic modeling aids the geophysicists to have a better understanding of the subsurface image before the seismic acquisition, processing, and interpretation. In this regard, seismic survey modeling is employed to make a model close to the real structure and to obtain very realistic synthetic seismic ...  Read More

4. Using a novel method for random noise reduction of seismic records

Majid Bagheri; Mohammad Ali Riahi

Volume 7, Issue 3 , Summer 2018, , Pages 65-72

http://dx.doi.org/10.22050/ijogst.2018.75178.1381

Abstract
  Random or incoherent noise is an important type of seismic noise, which can seriously affect the quality of the data. Therefore, decreasing the level of this category of noises is necessary for increasing the signal-to-noise ratio (SNR) of seismic records. Random noises and other events overlap each ...  Read More
