Software for Gravel Packing Fluid Displacement Operations

GravelPackSim is a transient flow simulator that can be used to model gravel pack displacement operations in a laboratory environment and serves to aid in the proper design of experiments. This program allows you to calculate proppant bed heights and pump pressures for various calculation scenarios and options.

Well/Screen Annulus Configuration
GravelPackSim provides a database of standard pipe sizes to configure the casing. Well deviation is assumed to be horizontal for the simulations performed to design laboratory tests. The gravel packing assembly can be configured by specifying inputs for the screen, wash pipe, and blank pipe.

GravelPackSim provides utilities for unit conversions and importing old projects.


Liquid slurry is configured by specifying inputs for the base fluid, proppant properties, and concentration. Two types of slurries can be created in GravelPackSim. These are broadly classified into Newtonian and non-Newtonian liquid slurries. Non-Newtonian liquid slurry behavior is characterized by a power-law model. Typical slurry base liquids are water and brines. For steady-state calculations, the exact location of the slurry front can be specified n the well/screen annulus along with a packing progress stage. However, in the case of transient calculations, the location of the slurry front is determined at each time step.

Calculation Scenarios and Options
Calculations can be performed in both steady-state and pseudo-transient modes. Typical calculation scenarios are included to find the unknown pump and return pressures. In addition, the well/screen annulus flow can be separately modeled. In these calculations, proppant concentration, fluid leakoff, and dimensionless design bed height are inputs. Calculation options include temperature, pipe roughness, and screen assembly eccentricity specification. Parametric studies can also be performed on pump/return pressures and flowrates.
