Factors Affecting Drill Bit Balling Up▪️Formation – Clay stone and shale has tendency to ball up the bit even though you use highly inhibitive water based mud or oil based mud. ▪️Weight On Bit – High weight on bit will have more chance to create this issue. ▪️Hydrostatic Pressure in Wellbore – High hydrostatic pressure […]

Bit balling usually occur while drilling shale. Clay adhesion is a function of the electrochemical attraction of clay to clay solids and clay to metal (surface tension). The reaction begins when clay solids become wet, and hydration/dispersion of the clay occurs. Adhesion magnitude is determined by the degree of clay hydration, the chemical properties of […]

PDC Bits are the workhorses of the oil field. Features such as cutter types, cutter layout, and blade geometry are continuously being evaluated and improved to deliver value and drive down drilling costs. Certification with the IDEAS integrated dynamic design and analysis platform ensures these bits offer optimal performance. Additionally, the IDEAS platform and field […]

Types of Drill Bits Drill bits are broadly categorized into two main types: roller cone bits and fixed cutter bits. 1. Roller Cone Bits Roller cone bits, also known as tri-cone bits, feature three rotating cones equipped with cutting elements. These bits are commonly used in various formations, from soft to hard rock. a. Milled […]

1. Drill bitsAs we all know a natural resource such as ground water, brine, natural gas, or petroleum.Drilling to explore the nature of the material underground is best described as borehole drilling. Types of drill bit Roller cone bits can be further divided into two categories: milled-tooth and insert, and are designed to drill rocks […]
