Paper Number: SPE-196570-MS
... related to the effectiveness of fracturing stages, which by itself depends on the rock lithology and brittleness. We identified interaction among fractured intervals from diagnostic modeling of performance data that exhibited cross flows in the wellbore. On wells exhibiting the most prolonged duration of...

... Abstract Production from shales can be dependent on many things, including multiple reservoir properties, drilling, completion and production methods. Designs and analyses often focus on drilling and completion issues, such as number of stages, wellbore length and fracture properties, such as...

A simple ratio of the heel to toe recoveries can indicate that wellbore trajectory or excessive drawdown is potentially affecting the lateral's flowback profile. In this case a ratio of 2.2 indicates the toe trajectory in...
