... on identifying intervals' of unique pore geometry (rock type). This approach applies high level image analysis techniques of core material to quantitatively identify various pore geometries. When combined with more traditional petrophysical measurements on conventional core samples, various pore geometries (rock...

... popularity is that, for radial systems, the response appears as a horizontal line during the infinite-acting radial flow period, resulting in easier identification. However, when the semilog pressure derivative is applied to flow geometries other than radial, the responses are not horizontal; making...

... for an aqueous phase trapping problem. Techniques to minimize problems with aqueous and hydrocarbon phase trapping are reviewed, followed by discussion of methods to reduce or remove the effect of existing phase traps, such as increased drawdown, alteration of 1FT, alteration of pore geometry or direct removal...

... method. The method detailed uses a finite-difference 2D stream junction, open or closed boundaries, fractured or unfractured wells streamline tracking by contouring, volumetric analysis by geometry, and single-phase resistance by geometry. These steps are contrasted with an alternative method. Results...

... the techniques used to analyse lab data and field tests that can be used to help design and evaluate pressure induced fracturing. Both numerical modelling and field examples will be used to demonstrate the factors controlling fracture geometry, growth rates likelihood of length stabilization and more...

..., reservoir and simple outer boundary solutions as been reduced to a simple process for well test analysis specialists. However, coincident to these well test analysis advances, additional research has produced theoretical solutions for an increasing number of complex well and reservoir geometries found...

... a pump-in/ flow back test. The methodology developed in this paper has been successfully used in the field for the determination of the needed fracture parameters such as, fracture closure pressure, fluid loss properties, and fracture geometry from mini- or micro-fracturing tests. Introduction Mini...

... thermal conditions possible in both the inside and outside environment. A combined program of testing and mathematical modeling has been designed to predict system thermal response and permit seal optimization based on environment, geometry and conductivity. Testing Tests were run on several designs...

... approach in which there are two representative elementary volumes (REV's). One REV represents the fracture system, the other the matrix. As in all continuum approaches, the details of the fracture-system geometry are lumped into the properties of the continuum. Potentially important details...

... behaviors for power-law fluids in all three fracture geometries have been determined. Introduction Normal hydraulic fracturing treatment design calculations combine fracture mechanics, fluid mechanics, and a volume balance to predict fracture growth with time. Fracture mechanics relate fracture width...

Figure 1 shows DLS profiles for a deviated Alberta well based on surveys taken while drilling and a survey taken later at 10 meter intervals. Because the data used for Figure 1 is taken from a deviated well survey points taken...

.... The instability gives rise to sand production which is believed to be the major reason for (a) poor performance in the subsequent recovery projects (e.g. steam injection), (b) severe channelling in water floods, and (c) direct communication between offset wells. Furthermore, sand production alters the geometry...

Many fracturing fluids have been shown to deviate from the classical power law representation, and we examine the effects of using some of the more complex rheological models on fracture geometry and proppant placement in the fracture. The paper...

... Abstract An analytical method based on the finite element variation principle and fracture mechanics is proposed to assess the in-situ fracture of oil sands formations. The concept on which the method is based involves the optimization of: (1) the wellbore geometry with "fracture starters...
