Introduction to AutographPC Sizing and Simulation Software

Baker Hughes Centrilift AutographPC ™ is an artificial lift and application simulation software. It’s a powerful tool to give a comprehensive and user-friendly system design. This software can be used to design production systems, including: electrical submersible pumping (ESP) systems; electrical submersible progressing cavity pumping (ESPCP™) systems; rod-driven progressing cavity pumping (RDPCP™) systems; horizontal surface pumping (HPump™) systems; and gas lift systems, etc.

Each system installation is unique and with this software, all the well information, including production characteristics, fluid properties and well conditions, can be entered during the initial design phase to produce the optimum solution for each sizing.

Once installed and launched, Design Modes Screen, shown in the following screenshot, appears. Design Modes screen has been added to AutographPC since July 12, 2017. This is the screen where the user can select a design mode and start a new sizing program.

Guides to Flowing Gradient Survey Data from API RP 11 V5

The purpose of this article is to present rough guides, or “rules of thumb”, to consider when preparing a Flowing Gradient Survey job program for gas lifted well. These recommendations will guide Production Engineers when preparing the survey instruments, planning the survey stop depths and times, when planning to obtain the bottomhole pressure data, as well as when preparing the job program for running pressure & temperature survey.

 

Preparing the survey instruments:

  • Run sinker bars as needed to overcome pressure surges when entering the wellhead from the lubricator.
  • Sampling rate should be at 30-second intervals.
  • Calibrate the electronic gauge with its software prior to each use.
