... a sample and its PVT experimental results, and a compositional gradient is parametized using the DFA observations at the different depths. A polynomial fit is then given to the distributed pressure measurements and the obtained fluid density variations are compared to the fluid model ones. Artificial...

Paper Number: SPE-103315-MS
... Abstract Reservoir rock heterogeneity is an ever-present occurence in most reservoirs. One among reservoir properties that are the most affected by its presence is permeability. In most cases, reservoir rock heterogeneity causes permeability anisotropy or variations in permeability...

... that describes the variation of oil saturation with average pressure is presented. For constant oil rate production, the influence of gravity drainage on the inflow performance relationships curves is studied, and a new correlation is presented. For constant pressure production, the decline curve behavior...

... destabilize the displacement. Furthermore, we considered the injection of different gases (reservoir gas and methane) at the same reservoir conditions, our simulation results show that the gravity force effect under small variations of density between the injected gas and reservoir gas has a big impact...

..., but also impacted by the variations of fracture opening. This conclusion can be used to better define the optimal rate for the reservoir under different reservoir pressures, thus further improve our forecast accuracy and overall field development results. reservoir pressure fracture closure degree...

... factors complicating the well-test interpretation are also discussed. Pressure derivative analysis is shown to be very useful in identifying the permeability variation. The logarithmic slopes basically reflect the combined variations of permeability, producing thickness, flow rate, and fluid properties...
