Alto do Rodrigues GeDIg pilot - Case study for continuous steam injection recovery combined with Real Time Operation

Abstract

Abstract Alto do Rodrigues (ARG) is an onshore heavy oil brownfield with continuous steam injection recovery located in the Rio Grande do Norte and Ceara Business Unit in the Northeast of Brazil and it was chosen as a pilot in Petrobras corporative program for Digital Integrated Field Management - GeDIg. The ARG pilot consists of on-line monitoring of bullhead temperature of producers and injector of five spot networks connected with steam facilities measurements such as pressure and steam quality. The real time operation is combined with two collaborative environments integrated with SOLAR, an in-house development collaboration software. Reservoir heterogenerity analysis like steam channeling is provided when steam generators parameters, well instrumentation, and historical data are combined in new workflow processes of steam analysis. Change management associated to process mapping guided the pilot implementation to minimize the side-effects of new process absorption. The objective of this paper is to present the methodology and results from Digital Integrated Field Management in the onshore heavy oil brownfield of Alto do Rodrigues. Introduction Petrobras defined a corporate strategy for implementing the company's vision os Digital Oil Fields. This program is called GeDIg - Digital Integrated Field Management [1]. Alto do Rodrigues is one of the project pilots chosen in this program to persue ultimate recovery augmentation, oil production optmization, and operational cost reduction through the digital integrated management of oil and gas fields. Specific goals of GEDIG activities are: train people, apply information, automation, simulation and modeling technologies. Alto do Rodrigues (ARG) is an onshore heavy oil brownfield with continuous steam injection recovery located in the Rio Grande do Norte and Ceara Business Unit in the Northeast of Brazil (Figure 1). This paper focuses on the analysis of continous steam injection recovery over a single five spot network, which represents a cell of the field draining network that is under development as part of a major steam pipeline project the will cover all the Alto do Rodrigues asset. It describes many aspects concerning people, processes, and technology involved in the implementation of the project.
