Introduction to AutographPC Sizing and Simulation Software

By Islam Fetoui | 20 February 2018 - 19 h 29 min |21 February 2018 ESP, Petroleum Softwares

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.

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.

INTRODUCTION

ALS MANAGEMENT CONCEPTS. The comprehensive management cycle of Oil field development using ALS´s, involves different inherent processes and participants, which makes necessary an integral scheme of management. Identifying each of the stages and people who take part in the processes is fundamental to be able to optimize existing procedures or implement a comprehensive medium and long-term management strategy. The scheme in Figure illustrates a management cycle during ALS´s implementation and operation, and can serve as a guide to analyze different aspects of the whole process. Two stages are identified: initial evaluation, for initial selection and implementation; and the Integral Management ALS Cycle, which by its own development, it becomes in a positive feedback cycle (virtuous circle) where different work participation areas and interdisciplinary work becomes key factors for a correct management.
