Attenuation law of MWD pulses in aerated drilling
Petroleum Exploration and Development, 2012 A mathematical model for predicting the attenuation of measurement while drilling (MWD) pressure pulses in aerated drilling was proposed using the two-phase flow model and considering the momentum and energy exchange at the phase interface, gravity of ...

Gas holdup in a gas-liquid-fiber semi-batch bubble column [PDF]
, 2005 A 4-m high, 15.24-cm diameter semi-batch bubble column connected to one of three perforated plate gas distributors with open area ratios A = 0.57%, 0.99%, and 2.14% is employed to study gas holdup and flow regime in Rayon and Nylon fiber suspensions ...

Local Gas Holdup Variation in a Fiber Slurry [PDF]
, 2005 Air−water−fiber flows are found in the pulp and paper industry in a variety of unit operations. Understanding the complex hydrodynamics found in such flows is beneficial to flotation deinking (i.e., a separation process found in paper recycling) and ...

Contractual Holdup and Legal Intervention [PDF]
, 2007 This article develops the point that incentive and risk-bearing problems associated with contractual holdup may justify legal intervention. Contractual holdup is considered both for fresh contracts and for modifications of contracts.
