A Production-Based Method for Direct Estimation of Gas-in-Place and Reserves
نویسندگان
چکیده
This paper presents a systematic method for the direct estimation of gas-in-place and reserves using only gas production data. The fundamental concept used in this work is "quadratic" rate-cumulative relation, which is given as: 2 2 1 p i p i gi g G G D G D q q + − = ................................................... (1) Where we define the decline constant, Di, for this case as:

Identification and Evaluation of Unconventional Hydrocarbon Reserves: Examples from Zagros and Central Iran Basins
It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...
متن کاملEstimation and Modeling of Biogas Production in Municipal Landfill
The municipal solid waste in Landfill is transformed into landfill gas during a biochemical conversion process called bio-degradation. Gas release from landfills has potentially different environmental effects; therefore, assessing and forecasting the rate of production and release of gas from landfill sites is important for designing these sites and for the successful exploitation of gases as ...
متن کاملProduction Data Analysis in a Gas-Condensate Field: Methodology, Challenges and Uncertainties
Production data analysis techniques have been widely used for estimating reservoir properties such as gas in place and average pressure. Knowledge of this information is crucial for proper reservoir management. The present study discusses the roadmap, challenges and uncertainties for analyzing production data in an Iranian gas-condensate offshore field. This work is an integrated study in...
متن کاملSPE 139118 Production Analysis and Well Performance Forecasting of Tight Gas and Shale Gas Wells
Estimation of reserves in tight gas and shale gas reservoirs is problematic due to the low to ultra-low permeability characteristics of these reservoir systems. The sole application of conventional decline curve analysis methodologies often yields erroneous reserve estimates. Therefore, the use of theoretically-based production analysis techniques has become a must to analyze well performance a...
متن کاملEstimation cost of occupational accidents by SACA method: A case study in one of the South Pars Gas Refinery
Introduction: Occupational accidents impose a lot of direct and indirect costs on the national economy of the country. Because, as a fact, resources are limited for reducing the risks and costs can affect the optimal investment in safety issues, the aim of this study was to calculate the economic costs of occupational accidents in one of the South Pars Gas Refinery, Assalouyeh, Bo...
