Hessam MansouriSiahgoli; Mohammad Ali Riahi; Bahare Heidari; Reza Mohebian

Volume 9, Issue 3 , Summer 2020, , Pages 102-115

http://dx.doi.org/10.22050/ijogst.2020.218837.1535

Abstract
  It is difficult to identify the carbonate reservoirs by using conventional seismic reflection data, especially in cases where the reflection coefficient of the gas-bearing zone is close to that of the carbonate background. In such cases, the extended elastic impedance (EEI) as a seismic reconnaissance ...  Read More

2. A Review of Reservoir Rock Typing Methods in Carbonate Reservoirs: Relation between Geological, Seismic, and Reservoir Rock Types

Ali Kadkhodaie-Ilkhchi; Rahim Kadkhodaie-Ilkhchi

Volume 7, Issue 4 , Autumn 2018, , Pages 13-35

http://dx.doi.org/10.22050/ijogst.2019.136243.1461

Abstract
  Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through petrographic studies of the thin sections prepared ...  Read More

3. An Impressive Impact on Well Productivity by Hydrochloric Acidizing of Vuggy Carbonate Reservoir: A Case Study

Abolfazl Hashemi; Seyed Reza Shadizadeh

Volume 6, Issue 3 , Summer 2017, , Pages 12-28

http://dx.doi.org/10.22050/ijogst.2017.53900.1335

Abstract
  Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on ...  Read More

4. Determination of Pore Pressure from Sonic Log: a Case Study on One of Iran Carbonate Reservoir Rocks

Morteza Azadpour; Navid Shad Manaman

Volume 4, Issue 3 , Summer 2015, , Pages 37-50

http://dx.doi.org/10.22050/ijogst.2015.10366

Abstract
  Pore pressureis defined as the pressure of the fluid inside the pore space of the formation, which is also known as the formation pressure. When the pore pressure is higher than hydrostatic pressure, it is referred to as overpressure. Knowledge of this pressure is essential for cost-effective drilling, ...  Read More
