New Generation of HTHP Water Based Drilling Fluid Changing Conventional Drilling Fluids Solutions

Abu Dhabi International Petroleum Exhibition & Conference, 2020
Abstract The conventional drilling fluid to drill the high-temperature wells are non-aqueous fluid. ADNOC used high-temperature water-based drilling fluid instead of nonaqueous fluid to drill the well successfully. High-temperature water-based drilling-fluid systems hold several advantages over non-aqueous systems from financial and ...

Application of Water Based Drilling Fluid - Total Fluid Management

IADC/SPE Drilling Conference, 2004
Abstract North Sea area environmental practice and focus on reduction of drilling costs have limited the discharges of drilling fluid and drilling fluid chemicals to the sea the last years. A method for efficiently recycling water based drilling fluids has been developed.

Preliminary Investigations on Glycol-enhanced Water-based Drilling Fluids

Mineral Processing and Extractive Metallurgy Review, 2000
Abstract This paper investigates the inhibitive effects of some water-based muds prepared with polymers, glycol and inorganic electrolytes formulated to reduce the instability of shaly formations encountered in the drilling of hydrocarbon wells. Experimental have been carried out by means of hot rolling test and capillary suction time techniques ...

Design of Water Based Drilling Fluid Systems for Deepwater Norway

SPE/IADC Drilling Conference, 2001
Abstract The technical demands placed on drilling fluids used in the deep waters of Norway differ dramatically from those encountered in any other deepwater basin. Unlike the deepwater of the Gulf of Mexico, West Africa or Brazil, seafloor temperatures here can dip as low as –2.5° C (27.5°F), with low ambient surface temperatures the ...

Effect of Surfactants on the Performance of Water-Based Drilling Fluids

2021
In the formulation of drilling fluids, different additives are used to optimize their rheological behavior and control the fluid loss throughout the drilling process. Surfactants, as one of these additives, play a vital role in sealing off the lost circulation zones and in controlling the rheological properties of the dispersions to meet the ...

Environmental Biodegradation and Drilling Performance of Water-based Polyampholyte Drilling Fluid

SPE/EPA/DOE Exploration and Production Environmental Conference, 2005
Abstract Some of drilling fluids are a mixture of many components including organic as well as inorganic polymers. In order to assure stable parameters and the required technological parameters of drilling fluids, all components must be resistant to downhole conditions.

Zero Solid Invasion Water-Based Drilling Fluid

SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, 2018
Abstract Reducing the filtrate volume and eliminating the solid invasion is very important and critical in drilling tight reservoir. This will eliminate water blocking which is the common problem in drilling tight gas formation. The objectives of this study are to evaluate the effect of using sodium silicate, assess the ...

Novel Water-Based Fluids for Oil-Sands Drilling

SPE Canada Heavy Oil Technical Conference, 2015
Abstract Drilling through oil sands poses a special challenge as a result of the sticky nature of bitumen and the unconsolidated nature of oil sands. Although bitumen adheres to drilling tools, causing high torque and drag and a reduced rate of penetration (ROP), the unconsolidated oil sands impose an additional difficulty associated ...

Improving HPHT Stability of Water Based Drilling Fluids

SPE/IADC Drilling Conference, 1997
AbstractA new method is discussed to improve the HPHT stability of conventional rheology modifiers and fluid loss polymers used in water-based drilling fluids. The method exploits the interactions of polysaccharides (e.g. xanthan gum, scleroglucan), cellulosics (e.g. CMC, PAC) and starches with polyglycols.
