Performanca Analysis of Liquid Lubricants Added to the Drilling Fluids ; Excessive torque is one of the most important problems in oil/gas drilling industry. Friction between wellbore/casing and drill string causes excessive torque. This study discusses performance analysis of drilling fluid lubricants, which are used as friction reducers in well-bore. Three different types of commercial chemical lubricants, which are fatty acid and glycerid based, triglycerid and vegetable oil based and polypropylene glycol based, diesel oil, and crude oil, which consists of different API gravity, paraffin and asphaltene value samples, were selected for the analysis. In the analysis, different lubricant compositions with the mixture of commercial chemical lubricants, crude oil and diesel oil, which were added to water based lignosulfonate mud, are tested on metal-metal contact surface by OFITE Lubricity Tester to determine the best lubricity/cost ratio of lubricant compositions. Moreover, effects of the lubricants on mud rheology and API fluid loss of mud, foam forming potential and cheesing/greasing of the lubricants and the influence of mud properties on lubricants (calcium, salt, pH and mud density) are examined.

performance analysis of drilling fluid liquid lubricants Sönmez, Ahmet; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2011) Excessive torque is one of the most important problems in oil/gas drilling industry. Friction between wellbore/casing and drill string causes excessive torque. This study discusses performance analysis of drilling fluid lubricants, which are used as friction reducers in well-bore. Three different types of commercial chemical lubricants, which are fatty acid and glycerid based, triglycerid and vegetable oil based and polypropylene glycol based, diesel oil, and crude oil, which consists of different API gravi...
Determination of hydrate formation conditions of drilling fluids Kupeyeva, Aliya; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2007) The objective of this study is to determine hydrate formation conditions of a multicomponent polymer based drilling fluid. During the study, experimental work is carried out by using a system that contains a high-pressure hydrate formation cell and pressure-temperature data is recorded in each experiment. Different concentrations of four components of drilling fluid, namely potassium chloride (KCl), partially hydrolyzed polyacrylicamide (PHPA), xanthan gum (XCD) and polyalkylene glycol (poly.glycol) were us...
Effects of nanoparticles on the performance of drilling fluids Bal, Berk; Kök, Mustafa Verşan; Gücüyener, İsmail Hakkı; Department of Petroleum and Natural Gas Engineering (2017) In this master thesis, effects of nanoparticles on the filtration and rheological properties of water-based drilling fluids are experimentally investigated. Four different silica nanoparticles are added into the lignosulfonate and bentonite based drilling fluids. By using data obtained at the end of this research, filtration and rheological properties of nanofluids are analyzed and compared with the base fluids at different temperatures. Two groups of experiments are conducted in this research. In the first...
Real-time-optimization of drilling parameters during drilling operations Eren, Tuna; Özbayoğlu, Mehmet Evren; Department of Petroleum and Natural Gas Engineering (2010) Real-time optimization of drilling parameters during drilling operations aims to optimize weight on bit, bit rotation speed for obtaining maximum drilling rate as well as minimizing the drilling cost. The process is considered to be formation specific. A statistical method such as multiple linear regression technique has been used for the drilling optimization. An extensive literature survey on drilling optimization was conducted for this research study. A model is developed for this purpose using actual fi...
A study on heat transfer inside the wellbore during drilling operations Apak, Esat Can; Özbayoğlu, Evren; Department of Petroleum and Natural Gas Engineering (2006) Analysis of the drilling fluid temperature in a circulating well is the main objective of this study. Initially, an analytical temperature distribution model, which utilizes basic energy conservation principle, is presented for this purpose. A computer program is written in order to easily implement this model to different cases. Variables that have significant effect on temperature profile are observed. Since the verification of the analytical model is not probable for many cases, a computer program (ANSYS...
