Distribution and Permeability of Stylolite-Bearing Horizons Within a Lower Cretaceous Carbonate Reservoir in the Middle East

Abstract: Stylolites and related pressure-solution features occur in many carbonate reservoirs. They are seams of insoluble residue that record the removal of rock by pressure dissolution. Stylolites may limit reservoir continuity by forming barriers or impedances to fluid flow. This core-based study documents both the distribution of stylolites and the variable impact of stylolite-bearing horizons on reservoir continuity for a Lower Cretaceous carbonate reservoir in the Middle East.

Surface‐consistent deconvolution

Abstract: Using first principles, I formulate surface‐consistent deconvolution as a problem in optimization, to which I apply methods for nonlinear least‐squares. To minimize processing artifacts, I avoid data transformations such as Fourier transforms or slant stacks. My deconvolution filters are computed as approximate solutions to a large, sparse, least‐squares system. Useful solutions are obtained in a few iterations, with each iteration equivalent in cost to performing a single‐trace deconvolution of the data. The use of optimization removes a great deal of uncertainty about the results of surface‐consistent deconvolution. If, with a given choice of filter length, etc., a good deconvolution can be obtained, it is obtained. I illustrate the method and its limitations with three instructive field examples. The first underlines the issues of uncertainty and reliability. The other two show how surface‐consistent deconvolution can degrade as seismic data depart from the surface‐consistent model by small and large a...

Method of monitoring fluids entering a wellbore

Abstract: In a borehole logging tool, a hot wire anemometer measures fluid flow entering or exiting the borehole (16) at the wall of the borehole. The logging tool has open aperture sensing pads (14, 15) mounted onto arms (12, 13) placed in mechanical contact with the wall that place the sensor pads at the wall surface. The sensor pads have an open aperture across their central area to permit fluid flow therethrough in such a manner that provides minimum disruption of flow between the borehole and the surrounding earth formations about the borehole being logged. Other sensors mounted on the sensor pad measure parameters such as fluid type, flowrate or fluid flow direction, as well as fluid properties including capacitance, dielectric constant and temperature of the passing fluid; or contain a shield attached at the end of the sensor pad upstream of the fluid flowing in the borehole center so as to minimize effects from fluids flowing in the center of the borehole.

Casing alignment tool

Abstract: An oil well casing alignment tool is disclosed wherein a casing section that has been elevated to an upright position, aligns the upright casing and locks it in a vertical position while permitting the casing to be axially rotated until it locks it into the sealing point of the previous casing section.
