1 35 th Gas-Lift Workshop Houston, Texas, USA February 6 10, 2012 OLGA for Wells interface with VPC Gas Lift Database Dewayne Anderson, Principal Consultant SPT Group, Houston Texas (USA) Feb. 6-10, Gas-Lift Workshop 1

2 Outline Steady-State, Multi-Steady-State, and Fully-Transient Tools OLGA Transient Multiphase Flow Capabilities for Gas Lift Systems OLGA Transient Results for Gas Lift Heading New OLGA Interface w/ VPC Database of GLV Performance OLGA Gas Lift Case References Feb. 6-10, Gas-Lift Workshop 2

3 Steady-State, Multi-Steady-State, and Fully-Transient Gas-Lift Tools Steady-State software tools are well-developed and wellintegrated for GL Design & Analysis Multi-Steady-State softwares also offer additional tools and capabilities to the Operator and Consultant OLGA for Wells offers a unique Fully-Transient tool: Identifies cases w/ NO Steady State (i.e., persistent slugging) Evaluates inherently transient ramp-up slugs, intermittent GL, etc. Can also study fully-integrated transients w/ entire GL system Feb. 6-10, Gas-Lift Workshop 3

4 OLGA Transient Multiphase Flow Capabilities for Gas Lift Systems In-Wellbore Transients Liquid Loading Casing Heading Multi-Pointing (w/ Off-Design water cut, etc ) Gas Robbing (i.e., w/ Dual Tubings that share Annular Lift Gas) Tubing Head Slugging Maybe no Multiphase Steady State? System-Wide Transients Upstream of GLV (e.g., GL Delivery System, Competing Wells) Downstream of Well (e.g., Fluctuating Production Line Pressure) Feb. 6-10, Gas-Lift Workshop 4
