The Clay Minerals Identification of Asmari Reservoir Formation in Maroun Oilfield

Shadi Mohavel; Golnaz Jozanikohan; Sohaila Aslani

Volume 32, Issue 4 , December 2022, , Pages 259-274


  The presence of clay minerals of any type, amount or distribution pattern in hydrocarbon wells causes numerous problems in the formation evaluation. In this research, 15 core samples from Asmari Formation in the Maroun Oilfield were selected in order to study the type and distribution pattern of clay ...  Read More

Identification of Clay Minerals Using Cation Exchange Capacity in the Early Cretaceous Shurijeh Sandstone Reservoir , Gonbadli Field, East Kopet Dagh Basin, North East Iran

M.A Sarparandeh; B Mehrgini; A Mollajan; F Sahabi; G.H Norouzi; G Jozanikohan

Volume 24, Issue 95 , June 2015, , Pages 231-238


  In evaluating the quality of the reservoir sandstone facies, clay usually has significant effect in reducing reservoir effective porosity, permeability as well as calculation accuracy of formation fluids saturation. There are several methods for identifying and measuring the amount of clay. In sandstone ...  Read More

Evaluation of Clay Content of Shurijeh Reservoir Formation Using Core Analysis in Gonbadli Gas Field, Eastern Kopet-Dagh Basin

G Jozanikohan; F Sahabi; G.H Norouzi; H Memarian

Volume 24, Issue 95 , June 2015, , Pages 239-252


  Clay minerals reduce the reservoir quality in different ways. They may cause mechanical problems in drilling and lead to petrophysicalmisinterpretations.Therefore,Clay typing is necessary for upstream petroleum exploration and production industry. In this paper, type, amount and distribution patterns ...  Read More
