Title: Innovations of James B. Day
Introduction
James B. Day is a notable inventor based in New Orleans, LA (US). He has made significant contributions to the field of drilling technology, holding a total of 3 patents. His work primarily focuses on improving the efficiency and reliability of drill collar connections.
Latest Patents
One of his latest patents is for drill collar connections. This invention features a threaded connection designed to enhance fatigue-life, which is crucial for connecting adjacent sections of a pipe string that undergoes bending, tensile, and compressive stresses. The connection includes a pin member that is threadedly engageable with a corresponding box member. The design aims for a bending strength ratio (BSR) of about 3.20 or greater, ideally between 3.20 and 4.00. The preferred thread form is a V-type thread with specific flank angles and root radius, along with additional design features to further improve fatigue-life.
Another significant patent by Day focuses on high gas sealability makeup for API buttress connections. This innovation allows threaded pipe sections to form a casing joint with proper sealing at the correct makeup torque. The design includes a first pipe section marked for proper axial engagement and a box member plated with tin. A thread lubricant containing Teflon is applied to ensure effective gas sealing, providing a simple visual method to confirm proper joint makeup.
