Abstract

This study aims are data acquisition, control and online modeling of an oil collection pipeline network using a SCADA «Supervisory Control and Data Acquisition» system, allowing the optimization of this network in real time by creating more exact models of onsite facilities. Indeed, fast development of computing systems makes obsolete usage of old systems for which maintenance became more and more expensive and their performances don't comply any more with modern company operations. SCADA system is a telemetry and control system adapted for particular requirements of an oilfield management. Thanks to its different functions, we take advantage of this system to solve production problems especially those related to oil collecting pipeline network. In fact this network is confronted to some problems, in particular pressure losses which has significant effect on the production. This problem can be taken under control by the awareness of pipeline network operation and all its process data (especially junctions) in real time. This will allow online creation of representative and accurate computerized models for the oil collecting pipeline network including producing wells, collecting pipelines, manifolds and others facilities.

Highlights

Techniques used to manage, control and maintain oilfield wells, became more and more expensive on one hand and on the other hand performances of these techniques, in front of fast development of computing systems, doesn’t meet any more with the requirements of modern company operations
In order to make this study to be even more efficient, we suggested to deport a terminal to the oil collection department office, this will help engineers to monitor operation and modeling of Hassi Messaoud oilfield pipeline network in real time

Summary

Introduction

Techniques used to manage, control and maintain oilfield wells, became more and more expensive on one hand and on the other hand performances of these techniques, in front of fast development of computing systems, doesn’t meet any more with the requirements of modern company operations. More than this, supplied data are neither complete, nor precise to allow technicians quick intervention in order to correct onsite possible problem It is on one hand an issue of renovation and on the other hand with the aim of optimizing the management of the installations (wells, manifolds and satellite centers), that large oilfields (like Hassi Messaoud one) has been equipped by a very powerful supervision and acquisition SCADA system. On one hand an issue of renovation and on the other hand with the aim of optimizing the management of the installations (wells, manifolds and satellite centers), that large oilfields (like Hassi Messaoud one) has been equipped by a very powerful supervision and acquisition SCADA system This system has for role to collect all the data in real time from field, thanks to a telemetry network working in the UHF (Ultra High Frequency) radio band. Oilfield pipeline network for oil collection may contain several junctions which connect two production pipes of two or several wells
