... 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...

We will also briefly touch on some possible reasons for improved refrac well performance, based on computer simulation / history matching. drillstem testing depletion refrac control restimulation hydraulic fracturing production uplift...

... then explains how this model was tuned to enable a production and pressure history match. There is also a section devoted to the generation and utilization of a critical correlation between pressure depletion and a combined fracture half-length times the square root of permeability (Xf.√k) parameter which...

... documentation must be filed for each reserve record and the focus becomes the economic analysis of those reserves which is critical for future development especially in a very volatile economy in which prices are fluctuating a lot. depletion date cum cal reservoir surveillance lease review forecast...

... 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...

... access these reserves however, historical completion practices had to be redefined, given the reservoir's fluid sensitivity and the need for better stimulation in this low permeability, pressure-depleted system. Completion optimization focused on acid system design, diversion and debottlenecking...

... with the number of wells in the project. Cases evaluated in this study included realistic well spacings and production rates and a significant amount of depletion at the infill locations. Due to its speed, accuracy and reliance upon readily available data, the moving window technique can be a useful screening...

... Abstract This paper describes the application of a practical technique to determine infill potential when faced with little time, large data sets, and complex geology. Using this technique, we determined where newer wells are encountering potentially depleted reservoir and the infill potential...

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

... attractive than conventional pressure depletion for lower permeability formations where the loss in permeability with pressure decline is significant. Nitrogen injection economics are shown to be very sensitive to the costs associated with injection and separation and are adversely affected by reservoir...

... Abstract A correlation was developed that relates the composition of the well stream effluent at any depleted state to the composition of the retrograde gas condensate at its initial dew point pressure as a function of the fraction that the reservoir pressure is depleted, reservoir temperature...

... ABSTRACT In hot, high pressure gas condensate reservoirs significant vaporization of connate water can occur during depletion. As the reservoir pressure decreases, the equilibrium water vapor content of the reservoir gas increases, causing connate water within the gas-bearing portion...

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