ABSTRACT. Barium sulphate scale formation can occur readily in the wellbores of the Forties field when produced water containing a high barium ion concentration mixes with injection sea water of a high sulphate ion concentration. Typically scale formation begins with the onset of sea water breakthrough into a wellbore and can …

Within the domain of milling operations, the direction of rotation for the milling cutter typically remains constant, while the direction of the feed may vary. This dichotomy has given rise to two predominant milling methodologies: conventional milling, also known as up milling, and climb milling, frequently denoted as down milling. ...
