Abstract: In this study a technique is provided for determining formation pore pressure and flow properties based upon analysis of shut-in drill pipe pressure. Both radial and spherical transient flow ...

Abstract: The paper provides solutions for predicting directional tendencies of slick and single stabilizer bottom-hole assemblies (BHA) in curved boreholes. Solutions are derived in a curvilinear system ...

Abstract: This paper focuses on the use of the 3-D drilling trajectory equations derived from the concept of constant curvature. It is shown that the constant curvature equations are specially useful ...

Abstract: The greatest limitation of the spallation process is its inability to spall (or to consistently spall) many rocks encountered in petroleum drilling and mining operations. The New Mexico Institute ...

Abstract: A new test facility was designed and constructed to simulate flow in a horizontal well with a single perforation. A total of 635 tests were conducted with Reynolds numbers ranging from 5000 ...
