ROD PUMPING DESIGN, ANALYSIS, OPERATIONS

ROD PUMPING DESIGN, ANALYSIS, OPERATIONS

Discipline: Production Engineering

Level: Basic/Intermediate

Duration: 40 hours

Instructor: Hector Partidas

Purpose

To update and capacitate the personnel in the operating oil field companies in charge of the field data analysis in order to optimise the whole installation in the surface as well as the sub-surface by using the latest technologies in the field.

Designed

Specially designed for both Engineers and Technicians in charge of the field operations optimisation and upgrading.

You will learn

  • Knowledge of the components of the whole system
  • The key parameters to look at to achieve the best production rate while maintaining the integrity of the reservoir.
  • How to design the sub-surface equipment including gas segregators if needed
  • The different types of sub-surface pumps to be used according to the well conditions
  • The different types of surface pumping units to be used based on the well loads
  • How to calculate the balancing loads to preserve the integrity of the gear box
  • How to interpret the dynagrams and calculate the pump loads
  • A methodology to eliminate Floating Sucker Rod String if present, especially in heavy oil or those wells where some paraffin is present.
