Graphene Effect on the Rheological Behaviour of Drilling Fluid
, M.Sc. Thesis Sharif University of Technology ; Ramezani Saadat, Ahmad (Supervisor) ; Jamshidi, Saeed (Supervisor)
Abstract
Since the early 90s, nanotechnology has contributed to several developments in a wide range of Science and industry such as medicine, Physics, Chemistry, Aerospace, electronics and Biology. In recent years, nanotechnology has also made development in the oil and gas industry. The drilling fluid is already one of the most important parts in drilling operation.The physical properties of a mud, rheological properties and minimize fluid invasion into the formation with perfect mudcake are important to assist in optimizing results. Nano-materials as one of the achievements of recent years are effective in achieving these purposes. To obtain the above properties, a variety of polymers as...
A novel field applicable mud formula with enhanced fluid loss properties in High Pressure-High temperature well condition containing pistachio shell powder
, Article Journal of Petroleum Science and Engineering ; Volume 162 , March , 2018 , Pages 378-385 ; 09204105 (ISSN) ; Ramazani Ahmad, S. A ; Jamshidi, S ; Fellah Jahromi, A ; Sharif University of Technology

Abstract
Sustainable technologies are the main concerns of the 21st century modified oilfield industries. The insufficiency of conventional drilling fluid formulations with a combination of hardly degradable hazardous chemicals as additives raise the demands of field-applicable innovative and environmentally friendly methods. Pistachio Shell discards as degradable wastes, which can intellectually apply in drilling fluid formulation. The experimental oilfield investigations of utilizing pistachio shell powder prove the significant enhancement of rheological properties, reduction of fluid loss and mud cake thickness in both API (Low Pressure —Low Temperature) and High Pressure—High Temperature (HPHT)...
Numerical Evaluation of the Influence of Hydro-Mechanical Factors on the Conventional Methods of Hydraulic Fracture Analysis in Oil Reservoirs
, M.Sc. Thesis Sharif University of Technology ; Pak, Ali (Supervisor)
Abstract
The exploitation of oil and gas has been changed dramatically since the advent of hydraulic fracturing. Hydraulic fracture is one of the enhanced oil recovery methods in which high-pressure injecting fluid is pumped into the well to overcome the lowest in-situ stress and rock resistance to create cracks in the deep-rock formations. It is estimated that the benefits of the mentioned method lead to a net economic profit of $48 billion per year in the world’s oil and gas industry.While there are various analytical models for predicting hydraulic fracture characteristics, KGD and PKN are amongst the most popular Models. The conditions of plane strain in two-dimensional space are taken into...
