In this study, we use both methods to history match the production of hydraulically fractured unconventional wells, followed by forecasting future production to establish a well's EUR (Estimated Ultimate Recovery) for reserves determination purposes. This study's goal is to quantify the differences one might...

... Abstract Hydraulic fracturing is the most effective technique used to stimulate very low permeability reservoirs. A significant body of literature on hydraulic fracturing has been primarily devoted to optimization of fracture propagation and proppant placement. However, the chemical...

... can create localized "pressure sinks." When a nearby infill well is fractured, the hydraulic fracture grows towards areas of lowest stress (the depleted area), which can damage the parent well. Subsequently, the production potential of the new well is decreased because it is now draining from the same...

In particular, we investigate the impact of hydraulic fracture height, delayed drilling of the vertically offset horizontal wells, as well as horizontal well interference between Middle Bakken and Three Forks. The simulations...

... of hydraulic fracture and multi-stages fracturing can mitigate the negative effects on the formation of condensate bank, but the effects cannot be completely removed. A huff-n-puff methane injection has been proven to be an effective method to reduce the effect of condensate by maintaining the reservoir...

During testing, load cell volumes range from the standardized 4lb/ft 2 to the modified 0.5 and 0.25lb/ft 2 . 0.5 and 0.25lb/ft 2 volumes simulate proppant behavior in hydraulic fractures with frac widths...

... Abstract Hydraulic fracturing operations require large amount of water which, in some cases, could reach six million gallons per treatment. Fresh water, from surface and subsurface sources, is usually used to formulate the fracturing fluid. The use of produced water in hydraulic fracturing has...

Proppant transport models developed in this work fully incorporate the interaction between proppant particles and carrying fluid...

... Abstract The advent of horizontal drilling technology and hydraulic fracture completions has fundamentally altered the geometry of flow in shale gas systems, requiring new decline curves to forecast production. In this work we perform automatic decline analysis on Marcellus gas shale wells...

... Abstract The successful development of unconventional reservoir relies on the massive hydraulic fractures which provide high conductive paths and large contact area between matrix and wellbore. Since well production always shows a steep decline after the early high flow rate, refracturing can...
