3. A Physical-based Model of Permeability/Porosity Relationship for the Rock Data of Iran Southern Carbonate Reservoirs

Sajjad Gholinezhad; Mohsen Masihi

Volume 1, Issue 1 , Autumn 2012, Pages 25-36

http://dx.doi.org/10.22050/ijogst.2012.2772

Abstract
  The prediction of porosity is achieved by using available core and log data; however, the estimation of permeability is limited to the scare core data. Hence, porosity and saturation data through the framework of flow units can be used to make an estimation of reservoir permeability. The purpose of this ...  Read More

6. An Improvement in Thermal and Rheological Properties of Water-based Drilling Fluids Using Multiwall Carbon Nanotube (MWCNT)

Mostafa Sedaghatzadeh; Abbasali Khodadadi; Mohammad reza Tahmasebi birgani

Volume 1, Issue 1 , Autumn 2012, Pages 55-65

http://dx.doi.org/10.22050/ijogst.2012.2775

Abstract
  Designing drilling fluids for drilling in deep gas reservoirs and geothermal wells is a major challenge. Cooling drilling fluids and preparing stable mud with high thermal conductivity are of great concern. Drilling nanofluids, i.e. a low fraction of carbon nanotube (CNT) well dispersed in mud, may enhance ...  Read More
