Refracturing in unconventional plays has gained popularity in the past few years.  This has been due to multiple factors, including many of the older laterals being under-stimulated, improvements in degradable chemical diverters, low recovery factors in unconventionals, and operators trying to improve their overall capital efficiency.  Before choosing the appropriate method to divert and …

  An energy-based drilling mechanics methodology, the “DEMSE” method, has been developed and demonstrated to be useful in predicting pore pressure. The MSE and drilling efficiencies used in the DEMSE method are calculated from downhole drilling parameters and subsurface log data. The DEMSE approach, which is based on physical principles, is an improvement over the …
