Description

Production models may offer several challenges since they involve data entry subject to errors and reservoir parameter uncertainties. These challenges exacerbate when user needs to take decisions on a continuous basis and whenever a new alternative scenario needs to be evaluated.

In this effort, we present a workflow to externally manipulate integrated production model parameters (PI, Pres, Equivalent choke ID, Choke Correction) to automate the history match tuning process to reduce the error between actual field measurements and simulated integrated production model composed of several reservoir tanks, wells and surface pipeline network. A “Tabu Scatter Search” optimizer engine selected the best iteration parameters in accordance to the objective function.

Lowest uncertainty model parameters were selected from the objective function global minimum; e.g. well productivity indexes, reservoir tanks pressures, equivalent choke diameter and choke correction parameters where determined as a result of this workflow. Tornado plots and IPM performance curves under uncertainty where generated as a result of this application as well. On a similar workflow, decision parameters such as well alignment, choke position and other constraints are used to maximize system’s performance.

Luigi Saputelli is a petroleum engineer with 18 years experience in reservoir engineering, field development planning, production modeling, drilling engineering and planning. He holds a PhD in Chemical Engineering (2003) from the University of Houston, a M.Sc. in Petroleum Engineering (1996) from Imperial College of Science Technology And Medicine, London, and a Bachelor of Science, Electronic Engineering, 1990 from Universidad Simon Bolivar, Caracas, Venezuela

Luigi worked in Halliburton (2003-2009) where he acted as technical lead of various major projects such as Petrobras Barracuda-Caratinga fields Real Time Operations project (2005-2006), PDVSA integrated modeling and field exploitation plans for Carito and Orocual fields (2006-2007); he later acted as Production Operations Regional Practice Manager and Field Development Global Practice Manager for Halliburton. He also worked in PDVSA E&P (1990-2001) and acted as a well planning senior advisor, production technologist, reservoir modeling and simulation engineer.
 
He has worked in several countries such as Venezuela, Argentina, Brazil, Colombia, Scotland and USA. He is an industry recognized researcher, lecturer, SPE Liaison and committee member. His main areas of interest area of integrated reservoir modeling and simulation for improved oil recovery projects, field development, drilling and well planning projects, drilling rig automation, production operations and oilfield automation projects. He has published more than 40 industry papers on applied cutting edge technologies for reservoir management, real time optimization and production operations. He currently works for Hess as Sr. Production Modeling Advisor.
