Chelating agents show very effective performance in different applications in the upstream
oil and gas industry. This study presents a critical review of the application of chelating …

Hydrochloric and organic acids have been extensively used to enhance well productivity or
injectivity in tight carbonate formations (10 to 50 md). The use of these acids, however, can …

Designing drilling mud rheology is a complex task, particularly when it comes to preventing
filter cakes from obstructing formation pores and making sure they can be easily …

Barite is one of the most common weighting materials used in drilling fluid for deep oil and
gas wells. Consequently, the main source of solids building the filter cake is the weighting …

Drill-in-fluids create what are known as filter cakes. Filter cakes, in some cases, lead to well
abandonment because they prevent hydrocarbons from flowing freely from the formation into …

Formation damage has a negative impact on the productivity of a well. Hence, its
mechanism needs to be well understood to be able to mitigate it. Secondary damage is a …

Using seawater or engineered water to inject into oil formations can cause inorganic scaling,
such as calcium sulfate, barium sulfate, and strontium sulfate. These scales may clog pore …

Solutions that rely on chelating agent are widely implemented in upstream oil and gas field
processes, due to their unique performance and their ability of capturing specific ions. There …

Comparative assessment experimental study was conducted for high density NaBr and
CaCl2/CaBr2 brines and water-drilling fluids based on manganese tetraoxide and barite as …

The focus of this chapter will be on corrosion during downhole oil and gas treatments such
as matrix acidizing, inorganic scale removal, and mud filter cake removal. The chapter will …
