Utility
Method and device for estimating sonic slowness in a subterranean formation
7 Sep 21
A method for estimating sonic slowness comprising: obtaining (700) a plurality of sonic waveforms are received by a plurality of receivers of a logging tool after emission of a source sonic wave by a transmitter, obtaining (710) slowness models of the subterranean formation, a slowness model being defined by a at least one cell of constant slowness for at least one wave energy mode, computing (720), for each slowness model, a set of candidate travel times, a candidate travel time of a set of candidate travel times being computed for a wave energy mode and a position of a receiver of the plurality of receivers, computing (730) a relevance indicator for each set of candidate travel times based on the recorded sonic waveforms; searching (740) a match between the sets of candidate travel times and the recorded sonic waveforms by searching a relevance indicator which is optimum, computing (750) a sonic slowness estimate for the subterranean formation from a set of candidate travel times for which the relevance indicator is optimum.

Utility
Data fusion technique to compute reservoir quality and completion quality by combining various log measurements
7 Sep 21
Methods may include normalizing two or more wellbore logs obtained from the output of two or more wellbore tool surveys of a wellbore in a formation of interest; inputting two or more wellbore logs into a correlation matrix; assigning each of the two or more wellbore logs a positive or negative value based on the impact on a selected wellbore quality; performing a principal component analysis of the two or more wellbore logs to obtain one or more loading vectors; computing weighting factors for each of the two or more wellbore logs from the one or more loading vectors; and generating a quality index by linearly combining the two or more wellbore logs using the computed weighting factors.

Utility
Wellbore annular safety valve and method
7 Sep 21
A method includes deploying a tubing having a tubing bore in a casing in a wellbore, the tubing including a cup packer forming an annular barrier across a tubing-casing annulus separating the tubing-casing annulus into an upper annulus and a lower annulus, the cup packer having a fluid conduit extending substantially parallel to the tubing bore, and a barrier valve coupled with the fluid conduit to permit one-way fluid flow from the upper annulus to the lower annulus, communicating a fluid from the upper annulus through the barrier valve to the lower annulus, and closing the barrier valve in response to pressure in the upper annulus being less than pressure in the lower annulus.
