Application Of Decline Curve Analysis To Unconventional Reservoirs, Majed Hisham Kabbani

Graduate Theses, Dissertations, and Problem Reports

Supply and demand are the main key factors for oil and gas industry. Moreover, natural gas was not important until early 18^th century after the World War II. The first shale gas well was successfully drilled 27 ft deep in 1821. The well was drilled in the Devonian Dunkirk shale. Later in the 1980s producers began investigating into the more difficult tight gas sands in order to keep up with the growing market. A decade later in 1990s investors were looking at coalbed methane. Today, as demand is increasing globally, the oil and gas industry is moving toward shale. …

Application Of Decline Curve Analysis To Unconventional Reservoir, Ahmed Wasel Alqattan

Graduate Theses, Dissertations, and Problem Reports

The oil and gas industry has been dealing with the unconventional reservoirs for about only two decades. Consequently, many challenges remain in evaluating the unconventional reservoirs. A few of these obstacles are the absence of the adequate production history, understanding the fluid flow regime after hydraulic fracturing, and estimating the drainage volume of the reservoir. One of the essential elements for evaluation of the oil and reservoir is to estimate the production rates over time in order to investigate the economic potential of the project.

Decline Curve Analysis (DCA) is most common the methodology for predicting the production rates over …
