A two-dimensional (2D) seismic survey is a geophysical data acquisition program in which seismic receivers are deployed along a single line and seismic energy sources are fired along the same line — recording… Read more →

The two-pass method in drilling fluid hydraulics is a calculation procedure for optimizing drill bit nozzle sizing and surface pump pressure allocation between two flow objectives — maximum hydraulic horsepower at the… Read more →

Two-phase flow in petroleum production refers to the simultaneous flow of two immiscible fluid phases through a conduit — most commonly gas and liquid (oil or water) in production tubing, pipelines, or gathering… Read more →

A two-phase separator is a pressure vessel used in oil and gas production operations to separate a multiphase fluid stream (a mixture of gas and liquid) into two distinct phases — a gas phase and a combined liquid phase… Read more →

Two-way travel time (TWT) is the elapsed time for a seismic wave to travel from its source down to a given subsurface reflector and back up to a receiver at the Earth's surface, and it is the fundamental measurement… Read more →

A type curve in petroleum engineering is a dimensionless reference plot of pressure change and its derivative (or production rate and its decline) versus time, derived from analytical solutions for idealized reservoir… Read more →

What Is Type Curve Analysis? Type curve analysis is a reservoir engineering method for interpreting well performance and estimating reserves by matching a well's production or pressure history to a set of dimensionless… Read more →
