A Tait-like Equation for Estimating the Density of Nontraditional Super Lightweight Completion Fluid at High Pressure and Temperature

Abstract

Novel nontraditional super lightweight completion fluid (SLWCF) has been proven to be the best means to ensure the success of underbalance perforation. Field test showed that the application of this new fluid has improved the well productivity. The authors present density measurements of SLWCF at high pressure and temperature. Density values of the fluid were measured in laboratory at high temperature ranging from 313.15 to 393.15 K, and pressure up to 25 MPa. Measured densities were fitted to a Tait-like equation. Calculated absolute average deviation, the maximum deviation, bias, and standard deviation values show that the developed model can be used to express the fluid density over a wide range of pressure and temperature. In addition, density value predicted by a Tait-like equation shows a good agreement both with laboratory and field data.

Coupled Fluid-Solid Geomechanical Modeling of Multiple Hydraulic Fractures Interacting with Natural Fractures and the Resulting Proppant Distribution

“…The differences in behavior is captured in the different constitutive equations used. The solid (rock) sample is modeled by an elastic isotropic material and the fluid pressure by a Tait equation (Li, 1967, Khalil, 2013. The fluid constitutive response is represented with a hyperelastic material with a volumetric strain energy function.…”

Rheological behavior and temperature dependency study of Saraline-based super lightweight completion fluid

“…In response to the above, an innovative Sarapar-based super lightweight completion fluid (SLWCF) has been successfully formulated to achieve the desired well pressure for underbalanced application (Badrul et al, 2009;Khalil et al, 2010aKhalil et al, ,b, 2011Khalil et al, , 2013. It was expected that the formulated SLWCF is able to create a cleaner perforation tunnel during gun detonation.…”
