The gas condensate fields, considering Camisea development, are setting a trend for hydrocarbon production in Peru, and during recent times the exploration projects are focusing on developing natural gas fields in the Peruvian jungle. This thesis aims to present a conceptual model of a production facility for conditioning natural gas and condensate. For this purpose, a hypothetical field is defined considering production volumes and compositions similar to those characteristic for a field in the southern Peruvian jungle . The design of the facility will follow oil industry criteria commonly applied in order to choose the best alternatives for selected treatment modules based on the characteristics of the proposed field. By simulating the production facility it will demonstrate the suitability of the election proposed to meet common technical and contractual for obtained streams, dry natural gas and stabilized condensate. This document evaluates different alternatives for each module, and according to process requirements, presents a decisions-based model for present a conceptual design for the production facility for the hypothetical field. The modules covered include Reservoir module, separation module, stabilization module, gas dehydration module and the heavy hydrocarbon gas recovery module. Decisions made for each module have the aim to minimize investment costs, reduce logistics associated cost, and seek the best return on investment, meeting technical requirements for each module. AII these assumptions take in account the nature of the remote location for the production facility. As input variables for the proposed simulation, well fluids characteristics and its surface conditions will be entered in order to control the following properties in each of the streams obtained: • The dew point for natural gas product • The Reíd vapor pressure (RVP) stabilized for the condensate The dew point is verified in the natural gas in order to ensure transport of this stream without the generation of hydrates or excessive pressure drops. For condensate stream, the mínimum content of light compounds will be monitored through Reid vapor pressure in the stabilized product. Commercial limits set for stream properties were defined based on knowledge of the typical trade agreements in Peru, for caloric content of the gas, as well as liquid quality that will be treated in order to obtain commercial products. Considering this fact, the main objective is to maximize production of liquids for obtaining transportable gas in specification . In order to verify the validity of the production facility proposed, results obtained with two alternative compositions from the base case will be tested: • lnlet composition with a higher content of heavier hydrocarbons . • lnlet composition with a lower content of heavy hydrocarbons. Finally, the economic viability of the project will be analyzed against a field development alternative that does not involve the installation of a production facility (which involves paying a processing fee to a third party operator). This will be reinforced with a sensitivity analysis for variations in processing fee, and their effect on the economic performance of the situation described.
