Università Roma Tre

Introduction to production systems. concepts ofprocess, indstrial plant, production system, industrial company. Classification of industrial plants and production systems. Make to stok and make to order production. main performance measures of industrial plants.

Introduction to decision making techniques (single and multiobjective, decisions in deterministic unacertainty and risk conditions). Linear programming method and application to optimal production mix definition.

Classification and quantification of industrial costs (fixed vs variable, investment vs operational, direct vs indirect, unit, average and marginal costs). Economic balance of a production system. Break even point, optimal production volume, make or buy decisions.

Design steps of an industrial facility. Technical and economic feasibility study (estimation of capital investment, operating cost and revenues), financial analysis, with emphasis on offshore oil and gas initiatives.
Profitability analysis of industial investments in both deterministic and probabilistic environment. Decision analysis about replacement and choice between alternative equipment.

Project management techniques: activities planning and representation (work breackdown structure, Gantt diagrams, graphs). PERT and CPM techniques for project control. Management of project costs. Anaysis of the phases of an oil and gas offshore project.

Aalysis of oil & gas offshore systems.
a) Types and characterization of hydrocarbons reservoirs. Estimation of reservoir size. Drive mechanisms and primary, secondary and tertiary recovery processes. Causes of reservoir productivity decline over time.
b) Physical characterization of reservoir fluids (phase diagrams, volume factors, density, viscosity, gas solubility in oil).
c) Technologies for wells drilling and hydrocarbon recovery (plants architectures and components, safety equipment, wells completion, characteristic curves of reservoir and tubing in stationary, transient and pseudotransient states, working point estimation, pressure losses for single and multi-phase flows, trubing sizing and nodal analysis procedure, gas lft suystems, forecast of reservoir productivity over time.
d) Offhsore oil and gas drilling and extraction infrastructures: types and classification (fixed and floating platforms, subsea systems) main components and selection criteria.
