Paper presented at the SPE Unconventional Resources Conference-USA, April 10–12, 2013
Paper Number: SPE-164550-MS
... with that work, our interpretation is that the early flowback data corresponds to wellbore + fracture volume depletion (storage) and it is assumed that fracture storage volume is much greater than wellbore storage. From this flow-regime, bulk permeability (dominated by fracture permeability) and effective...

... depletion, waterflooding and several forms of CO2 flooding. Only 3.64% recovery factor from primary depletion was calculated. Cherian et al (2012) investigated the impact of pressure depletion or timing of drilling on fracture geometry and well performance using simulation models. It was observed...

Paper presented at the CIPC/SPE Gas Technology Symposium 2008 Joint Conference, June 16–19, 2008
Paper Number: SPE-114952-MS
... Abstract There is concern within some factions of the energy industry about an approaching energy crisis. In the case of hydrocarbons, eventually there will be a maximum peak in global production. The question is if it will occur sooner or later, and if it will happen because of depletion...

The study shows that both water injection and gas injection result in higher recovery factors than normal depletion. Although gas injection...

The use of matrix controlled production information, derived from decline curves, appears to resolve this problem. production control...
