Proceedings Papers

Paper presented at the University of Tulsa Centennial Petroleum Engineering Symposium, August 29–31, 1994
Paper Number: SPE-27968-MS
... Abstract Relative permeability is a critical parameter in reservoir engineering calculations and performance predictions using numerical simulation. Little has been published on the effect of core-scale heterogeneities on relative permeability. Small-scale rock heterogeneity can lead...

Paper presented at the University of Tulsa Centennial Petroleum Engineering Symposium, August 29–31, 1994
Paper Number: SPE-27969-MS
... developed to describe phenomena which vary continuously throughout the reservoir, for example porosity, permeability or depth to geologic horizon. Note that the discrete models can be used to model continuous phenomena by modeling e.g. permeability classes. Similarily, continuous models may be used to model...

Paper presented at the University of Tulsa Centennial Petroleum Engineering Symposium, August 29–31, 1994
Paper Number: SPE-27982-MS
... A critical factor to the success of a matrix acidizing treatment is proper placement of the acid so that all of the productive intervals are contacted by sufficient volumes of acid. If there are significant variations in reservoir permeability, the acid tends to flow primarily into the highest...

...) are easily recognizable in core but not on most logs; (3) have very low porosity and permeability; (4) prevent or deter vertical flow between reservoir compartments and act as baffles to flow; and (5) are the focus of diagenetic clay formation. Because of the significant amounts of clay present in some tidal...

Paper Number: SPE-27993-MS
... Abstract Gas production from coal seams has been highly successful due to the use of open-hole completion techniques in the high permeability fairway of the San Juan Basin (Colorado and New Mexico) Fruitland Formation. Based upon extensive formation evaluation data collected during Gas Research...

Paper Number: SPE-27971-MS
... is high. If the fracture permeability (conductivity) variations in different zones are moderate, compared to the formation permeability, the multiple fractures have almost no effect on the pressure behavior of the system; the horizontal well dominates the system's pressure behavior. If the conductivities...

Paper presented at the University of Tulsa Centennial Petroleum Engineering Symposium, August 29–31, 1994
Paper Number: SPE-27973-MS
... Pressure-transient data from layered reservoirs used alone in analyses are highly non-unique if information on individual layers are sought. Results can also be misleading when such data are used to determine total flow capacity and average permeability of the system and to estimate a total...

Paper Number: SPE-28001-MS
... blocks and surrounding fractures. Litvak (1985) and Sonier et al. (1986) presented an explicit formulation to calculate gravity effects by assuming complete fluid segregation in fractures. Another modification to the basic transfer function is to use pseudo relative permeability and/or pseudo...
