Twenty performances predictions were run. Results showed that conversion of selected wells to injection and horizontal...

... Abstract It is important to be able to predict the instantaneous forces and moments at the bit during drilling, but the rock/bit interaction process is not thoroughly understood. It is commonly accepted that the forces acting on a drag bit should be balanced to avoid excessive bit vibrations...

Availability of such a model permits the determination of geometric and topological attributes of the 3-D microstructure which critically control the petrophysical properties of reservoir rocks. Prediction of various properties is then possible by incorporating information about...

This study presents a method for predicting the maximum stable injection rare profile for oil-water immiscible displacements in a five-spot pattern. The proposed method consists 0/ dividing the pattern in to plane-radial- and linear flow...

... Abstract Sound development decisions for coalbed methane reservoirs, require accurate determination of gas in-place and natural fracture permeability. The purpose of this paper is to outline procedures to evaluate reservoir properties required for prediction of well deliverability. The steps...

Pore pressure analysis is especially critical for exploratory and delineation wells but until recently our-predictive techniques were somewhat inadequate. This paper will present the application of seismic...

The standard deviation for the resistivity method is ±0.626% psi/ft. (or about ±63 psi per 10,000ft.) and the acoustic method is ±2.058% psi/ft...

... instead of assuming that formations rigidly constrain the casing in the vertical direction. The model requires only stratigraphic information and common wellhead dam to predict casing and formation temperature distributions from two-phase flow and heat transfer algorithms. Those temperature distributions...

... Abstract A combined laboratory/field investigation of the Cardium Formation was performed in an attempt to define specific rock properties for design purposes, and to compare the data with well-log predictions. The study included an extensive suite of well logs, physical rock property testing...
