Evaluation Of Prosper For Modeling Long Lateral Gas Well Productivity In Toe Up, Toe Down, Horizontal Well Geometry, Abdussalam Mahmoud Mohamed
Masters Theses
"Most horizontal wells are not truly horizontal and may be drilled 'toe-up' or 'toe-down' to follow geological formations or in an attempt to keep the well from loading up. Challenges in directional drilling may also lead to horizontal gas wells with undulating wellbore profiles. This wellbore profile creates natural traps for heavy fluids in the lows and light fluid in the highs, which may result in chocked production. Hence, there is an interest in determining the best wellbore trajectory - toe-up, horizontal, or toe-down - for well unloading.
This study evaluates the capability of the well productivity software PROSPER to …
Performance Comparison Of Transverse And Longitudinal Fractured Horizontal Wells Over Varied Reservoir Permeability, Fen Yang
Masters Theses
"Since the first application in the mid-1980's, multiple fractured horizontal wells have proven to be an effective means of extracting hydrocarbons. These wells require careful consideration of wellbore orientation relative to the horizontal principle stress. Wellbore orientation can lead to transverse fractures which are perpendicular to the wellbore, or longitudinal fractures parallel the wellbore. Questions arise regarding whether one fracture orientation is consistently preferred over the other, or if certain conditions affect the choice.
Historical work has examined the impact of horizontal wellbore azimuth in the Barnett and Marcellus Shale where public data was reviewed and statistical well analysis was …
