Abstract
Official abstract text for this publication.
Data transmission from a bottom hole assembly (BHA) includes obtaining a scan from multiple scans forming a downhole data log of a borehole within a subterranean formation. The scan includes a sequence of data items from a sensor in the BHA located in the borehole. Each data item corresponds to an azimuth angle of the sensor. Further, compressed scan data is generated from the sequence of data items on a per-scan basis, and transmitted, using a pre-determined borehole telemetry, to a surface unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for data transmission from a bottom hole assembly (BHA), comprising: obtaining a scan among a plurality of scans forming a downhole data log of a borehole within a subterranean formation, wherein the scan comprises a sequence of data items from a sensor in the BHA located in the borehole, wherein each data item corresponds to an azimuth angle of the sensor; generating, by a computer processor in the BHA, compressed scan data from the sequence of d…
