Abstract: A method is provided which transmits information using a plurality of data transmission nodes situated along a drill string. In this method, a first node obtains a transmission status of a second node. When the transmission status of the second node indicates that the second node meets a selected performance threshold, information is sent from the first node to the second node. When the transmission status of the second node indicates that the second node does not meet its performance threshold, then the first node obtains a transmission status of a third node. When the transmission status of the third node indicates that the third node meets a selected performance threshold, information is transmitted from the first node to the third node for relaying along the drill string.

Abstract: Non-contacting means of measuring the material velocities of harmonic acoustic telemetry waves travelling along the wall of drillpipe, production tubing or coiled tubing are disclosed. Also disclosed are contacting means, enabling measurement of accelerations or material velocities associated with acoustic telemetry waves travelling along the wall of the tubing, utilizing as a detector either a wireless accelerometer system or an optical means, or both; these may also be applied to mud pulse telemetry, wherein the telemetry waves are carried via the drilling fluid, causing strain in the pipe wall that in turn causes wall deformation that can be directly or indirectly assessed by optical means.The present invention enables detection of telemetry wave detection in space-constrained situations. The invention also teaches a substantially contactless method of determining the time-based changes of the propagating telemetry waves. A final benefit of the present invention is that it demonstrates a particularly simple contacting means of directly measuring wall movements in live coiled tubing drilling environments.

Abstract: A system and method of optimizing air hammer performance in a well drilling rig whereby an electronic acoustic receiver (EAR) is used to monitor the effects of changing any of the operating parameters under his or her control. The signals are visually presented to the drill operator based on an EAR's output, along with current settings, allowing the drill operator to dial in the parameters of his or her choice until the optimal frequency of the air hammer is regained. The visual output displays the amplitude response of acoustic waves being detected and decoded at the surface by the EAR. The drill operator can observe and use this information to determine the changes necessary in the operating parameters to return the hammer to optimal frequency, and thus optimal performance.

Abstract: An invention is claimed wherein the signal loss along steel drill pipe walls can be estimated in the absence of a loss mechanism due to the formation debris at various positions in the well bore; the signal loss in excess of the calculated attenuation is generally and directly attributable to the build-up of said formation debris and an estimation of the amount can be determined. Furthermore, by use of distributed acoustic nodes positioned in the well between the transmitter in the BHA and the surface receiver—configured as repeaters—the formation debris build-up can be determined in each section so defined. This new information enables the driller to implement hole cleaning means in a timely manner and as appropriate, thus avoiding the problems of getting stuck in the hole, and possible well abandonment. An extension of the method enables the hole cleaning process to be automated, thereby improving efficiency.

Abstract: A method whereby a downhole drilling transmission device that communicates to the surface automatically modifies its transmission parameters in order that it substantially improves its ability to adequately communicate with a surface receiver despite increasing signal attenuation between the two as the length of drillpipe increases. This utilizes a simple measure of localized downhole pressure that then relies upon a look-up table or similar that provides a correspondence between said pressure and measured depth. Such a look-up table or similar can be readily built by incorporating appropriate features of the planned well such as drilling fluid flow rate, drilling fluid density, drilling fluid viscosity, well profile, bottom hole assembly component geometry, drillpipe geometry, and indications as to whether the fluid is flowing or stationary.Upon determining the measured depth the tool then can attempt to modify or augment appropriate telemetry parameters in order to keep the signal received at surface within required parameters, thus offsetting the degradation due to increasing attenuation.

Abstract: An inventory and tracking system based on a labeling system is disclosed. Labels are provided for affixation to the product or product container. Each label includes, in addition to the standard information associated the product, a hologram associated with the product and a machine readable code. The machine readable code on each unit of product includes at least one set of unique machine readable identifiers that uniquely identifies each product unit. In addition, the hologram can include the trademark of the manufacturer or supplier, to permit the consumer to ascertain at a glance that the product originates from a source of known quality. The label on each unit is scanned before shipment and the destination of each unit of product is entered and stored. As the units of product are distributed through the distribution chain, the units are scanned, the destinations are stored and the information on the destination of the individual units of product are provided to the manufacturer, who maintains a master database that cross-references the machine readable identifier with the location of the product unit in the distribution chain. This master database also provides a historical record of the transit of each unit through the distribution chain. With this information in the master database, the manufacturer can determine the point at which the product entered the stream of commerce and whether or not the product entered the stream of commerce through an authorized source of distribution. Also, the manufacturer can quickly determine from the holographic label whether the product is authentic. The presence or absence of the unique machine readable identifier and hologram can confirm the product's authenticity or lack thereof.
