Paper Number: SPE-214628-MS
... Abstract Mud-induced damage is highly pronounced in horizontal wells due to the longer period of exposure to drilling mud and low draw-down pressure. Enzyme-based cleanup fluids are preferred for filtercake removal applications, especially in horizontal wells due to their several advantages...

... ): Abstract Currently, many horizontal wells are being drilled in Dadas shales of Turkey. Dadas shales have both oil (mostly) and gas potentials. Thus, hydraulic fracturing operations are being held to mobilize hydrocarbons. Up to 1000 m length horizontal wells are drilled for this purpose. However...

... technology with unique perforation position that can improve the efficiency of hydraulic fracturing of horizontal wells in low permeability reservoirs which have low porosity, low permeability and are difficult to explore. So it is important to know how fractures initiate and propagate as well as the optimal...

..., an average error of 2.1% was achieved for determining the absolute open flow (AOF). The developed IPR model offers a low-cost method to predict horizontal gas well deliverability. Another model to predict the productivity of fractured horizontal wells was presented by Lei et al. (2007) . They applied...

... Drilling horizontal wells can dramatically increase production, as the wellbore is exposed to the reservoir rock for an extended interval, as opposed to vertical wellbores which only intersect the reservoir. With the introduction of the downhole drilling motor in the 1980s, horizontal drilling...
