Gas-Oil-Water Production and Water-Gas Injection Forecasts in Williston Basin

摘要

Production and injection forecasts are of significance in terms of constructing infrastructure to accommodate the booming of unconventional oil and gas development and production in Williston Basin in North American (United States part). Underestimate or overestimate of future production will lead to an inappropriate plan of infrastructure development in this geographic area. Insufficient infrastructure will slow down the growth of hydrocarbon development and affect the revenue from fossil energy and the United States' (U.S.) energy security. Oversized infrastructure will result in waste of investment and leaving large footprint that impacts the environment significantly. Conventionally, production forecast is conducted at well or field level. A thoroughly literature review indicates that no study is available to predict the production of unconventional resource at basin level. To fill this gap, we propose a procedure to forecast the total production of a basin. Our study provides a guideline for forecasting production in a basin with similar geological settings.
