Development of Nanoparticles as Additive to Drilling Mud to be Used as Viscosity and Filtrate Loss Modifier
Abstract: Conventional drilling fluids are often unable to fulfill certain functional tasks that are very important in challenging environment. This inefficiency of drilling fluid in performing certain task is mainly because of lack in particular rheological or filtrate loss properties. Hence, the industry is looking for a new kind of additives which can be helpful in maintaining these properties in desired range even under extreme conditions. Rice husk is an abundantly …

Experimental Analysis of the Effect of Fine Milled Husk of Rice as a Novel Filtration Control Agent for Water Based Drilling Fluid System
Abstract: Drilling operation is a complex process that requires integration of various engineering systems. As the drilling continues, the formation encountered offers challenges to wellbore integrity as pressure increases with depth. The influx of formation fluid is contained by the overbalance provided by weighted drilling fluid column. Another critical function of the mud is to restrict the filtration fluid lost to the formation by forming a suitable mud-cake around the wellbore. …

Study the Rheological and Filtration Properties of Oil-in-Water Emulsion for its Application in Oil and Gas Well Drilling
Abstract: This research article investigates the rheological and filtration properties of oil-in-water emulsion required for oil and gas well drilling. The rheological and filtration properties of the emulsions were enhanced by varying concentrations of xanthan gum and CaCO3. The concentration of diesel oil was varied in the range of 5–30% (v/v). The concentration of xanthan gum was varied in the range of 0.25–1% (w/v) and CaCO3 in the range of 1–4% …

Drilling Fluid Characterization (Filtration Test)
Abstract: This report explores the formulation and testing of a water-based drilling mud used in drilling operations, where fluid circulates through the drillstring and returns to the surface. The study mixes 315 ml of water with 35 ml of corn oil to create the drilling mud and investigates the role of barite in increasing mud density to maintain a hydrostatic pressure capable of managing formation pressure. The findings reveal that increasing …

Development of Inhibitive Water-based Drilling Fluid System for Shale Formation
Abstract: The drilling of troublesome shale formations leads to severe wellbore instability problems due to swelling and dispersion of the shale cuttings in the welllbore. Hence, the formulation of inhibitive water-based drilling fluid system with enhanced rheological properties and filtration characteristics is a critical issue for these complex shale formations. This research article consists of a favourable drilling fluid system developed using potassium chloride (KCL), partially hydrolyzed polyacrylamide (PHPA), ethylene glycol …

Evaluation of Malting Potential of Different Barley Varieties
Abstract: The grain and malt quality parameters of six malt barley variety were studied. This study was conducted to estimate the malting potential of different barley varieties (Beka, Holker, HB120, Bahate, Bokoji, and Sabini) collected from Kulumsa Agricultural Research Center. All the grain and malt quality parameters were conducted in the laboratory of Food Technology and Process Engineering at the IOT, Bahir Dar University. The three stages of malting (steeping, germination, …

Problem of pricing American Fuzzy Put Option Buyer’s Model for general Trapezoidal Fuzzy Numbers
Abstract: Fuzzy American put option pricing in both discrete and continuous time by using fuzzy random variables and fuzzy expectation based on the decision maker's subjective judgement was studied by Yoshida. American Fuzzy Put Option Model (AFPOM) based on fuzzy risk-neutral probability measure was defined by Muzzioli and Reynaerts using non-overlapping trapezoidal fuzzy numbers. In this study, we introduce a new fuzzy risk-neutral probability measure for a more general class of …

Evaluation of Oil-Sorption Properties of Kapok Fiber for Cooking Oils: A Potential Check for Oil-ridden Wastewater from Restaurants
Abstract: Abstract Sewage is one of the leading sources of water pollution. The untreated water released from restaurants is the major contributor of oil pollution having devastating impact on aquatic life. Oil in water clogs pipelines, pumps and treatment equipments, decreases the efficiency of the plant and also results in high maintenance and operation costs. The natural material, kapok fibers have the capability to significantly separate oil from water by entrapping …

Chronic Renal Failure: A General Review
Abstract: Chronic renal failure is also known as chronic kidney disease in which there is progressive loss in kidney function over a period of months or years. The symptoms of worsening kidney function are not specific and might include feeling generally unwell and experiencing a reduced appetite. The definition of chronic kidney disease has been simplified over the last 5 years. It is now defined as the presence of kidney damage …

An Approach towards in Management of Chronic Kidney Disease
Abstract: The current international guidelines define and classify the chronic kidney disease (CKD) as decreased kidney function shown by decreased glomerular filtration rate (GFR). Glomerular filtration rate of 60 ml/min/1.73 m 2 for at least 3 months is a marker for kidney damage. The underlying causes for chronic kidney disease are proteinuria and hypertension. It is the main cause of CKD in many high-, middle- and low-income countries. In different countries, …
