Reservoir heterogeneity of Agbada Formation sandstone from PZ-2 well and PZ-4 well, Niger Delta: implications for reservoir management

A New Method for Predicting Well Pattern Connectivity in a Continental Fluvial-delta Reservoir

The features of bad flow unit continuity and multiple layers emphesize the importance of a well pattern design for the development of a fluvial-delta reservoir. It is proposed a method to predict well pattern connectivity (WPC) based on the exploration and evaluation of wells. Moreover, the method helps evaluate the risk of well placement. This study initially establishes the parameters for cha...

Hyperbolic-elliptic models for well-reservoir flow

We formulate a hierarchy of models relevant for studying coupled well-reservoir flows. The starting point is an integral equation representing unsteady single-phase 3-D porous media flow and the 1-D isothermal Euler equations representing unsteady well flow. This 2 × 2 system of conservation laws is coupled to the integral equation through natural coupling conditions accounting for the flow bet...

Compaction Localization in Porous Sandstone: Implications for Reservoir Mechanics

Compaction of porous rocks can occur in two modes: uniform and localized. Recent experimental work has demonstrated that compaction can occur in tabular zones that expand with increasing applied deformation. The appearance of compaction bands and their growth has a strong influence on the measured permeability of the host rock. The rock behind the moving compaction front can be either uniformly...

Growth in SL3(Z/pZ)

Let G = SL3(Z/pZ), p a prime. Let A be a set of generators of G. Then A grows under the group operation. To be precise: denote by |S| the number of elements of a finite set S. Assume |A| < |G| for some ǫ > 0. Then |A ·A ·A| > |A| , where δ > 0 depends only on ǫ. We will also study subsets A ⊂ G that do not generate G. Other results on growth and generation follow.
