ES100pc is a multi-phase flow pressure drop/systems analysis program pressure drop/systems analysis program designed to run on the IBM XT or AT. It has the capability to perform pressure loss calculations in wellbores, flowlines and pipelines. Inflow performance curve calculations are also available. Pressure loss in flowing or gas lifted wells may be computed. A number of multiphase flow pressure drop correlations are available. pressure drop correlations are available. The user may select correlations or enter data for the physical properties. Inflow performance curves may be calculated using performance curves may be calculated using a variety of correlations.
An input data preprocessor is available to assist the user in building his dataset. This processor allows the user to either create, edit or execute a dataset through a series of prompting messages.
ES100pc is a scaled down version of a mainframe program. over the past several years the mainframe program has been used by hundreds of engineers within ARCO with good results. The PC version yields results comparable to the mainframe program while allowing the engineer-the program while allowing the engineer-the autonomy and economy of a micro-computer.
In the past few years the personal computer has evolved into a relatively powerful workstation capable of performing powerful workstation capable of performing functions which were once the domain of mini and mainframe computers. The low cost of the PC is a powerful driving force for the downloading applications from the mini or mainframe computer. Other benefits include a potential for improved response time due to elimination of time sharing environment, and access to computing capabilities in areas where access to a mini or mainframe computer isn't available.
These factors are responsible for a widespread effort within ARCO to download engineering applications programs from the mini and mainframe computers to the PC. The most used in-house production engineering program in ARCO is ES100 which is a comprehensive software package which performs; multiphase flow pressure drop, performs; multiphase flow pressure drop, inflow performance, and artificial lift calculations. With the existing state of the PC it is not possible to download all the functions of the mainframe program; however, it is feasible to transfer some of the most used features of this program to the PC.
