Definitions

  • Embodiments herein generally relate to well drilling tools, and specifically to electronic communication of data and signals amongst such tools.
  • NPT Non-Productive Time
  • Sources of NPT include, for example, surface and downhole tool failures, rig repairs, waiting on weather, pulling of dulled bits, running and cementing casings, and waiting on logistics. Sources of NPT generally fall into four categories:
  • RM reactive maintenance
  • PM preventive maintenance
  • TPM time-based maintenance
  • RM Reactive Maintenance
  • the mean- time-between-failures (MTBF) trend line 100 indicates that a new machine has a high probability of failure because of installation problems during an initial period 102 of the first few weeks of operation. After this initial period 102, the probability of failure is relatively low for an extended period of operation 104. Thereafter, the probability of failure typically increases sharply with elapsed time during an end-of-life period 106. Using historical data, the time at which the probability of failure starts to increase sharply can be estimated statistically. In TBM preventive management, equipment repairs or rebuilds are scheduled based on the MTBF statistic.
  • a packer may not need a rebuild after six months, hence the labor and material used to make the repair was wasted.
  • the second option when using TBM is even more costly — if the pump fails before six months, it must be repaired using the run-to-failure management process. Better maintenance methods are needed to minimize unit downtime.
  • Embodiments described herein provide a protective component for a downhole tool, the protective component comprising a coupling for attaching the protective component to the downhole tool; and a wireless networking circuit for communicating data retrieved by the downhole tool to a surface data repository.

  • Condition based maintenance is a predictive maintenance methodology that uses the actual operating condition of equipment and systems to optimize total asset utilization. Instead of relying on average-life statistics to schedule maintenance activities, predictive maintenance uses direct monitoring data to determine the actual MTBF or loss of efficiency for each asset and system.
  • the common premise of CBM is that regular monitoring of the actual mechanical and electrical conditions, software status, operating efficiency, and other indicators of the operating equipment or system are required to achieve the maximum interval between repairs and minimize the number of unscheduled outages resulting from failures and thus minimize the associated costs.
  • the CBM approach enriched by active learning algorithms, applied to the continuously-acquired data will provide a detailed insight about the status of the equipment and trigger actions if a failure pattern is detected.
  • a considerable amount of equipment-condition data is usually timestamped, where a set of sensor readings are collected at the same time as timestamps and includes device identifiers.
  • CBM algorithms predict the expected time of failure “t” by using the historical data related to the condition of the tools and the operation.
  • Machine learning algorithms can be formulated in one of two ways: the classification approach or the regression approach.
  • the classification approach predicts whether there is a possibility of failure in the next n-steps.
  • the regression approach predicts how much time remains before the next failure.
  • the regression approach is also called the remaining-useful-life (RUL) approach.
  • the classification approach typically provides a “yes” or “no” answer, but can provide greater accuracy with less data.
  • the regression approach needs more data, although it provides more information about when the failure is predicted to happen.

  • MoT additionally monitors activities and conditions and provides remote control functions, but these capabilities can extend far beyond what MoT provides.
  • MoT technology can be used to monitor and control industrial production processes while capturing detailed data for quality management and documentation. Manufacturing execution systems can use lloT technology to closely monitor more parameters, resulting in the capability to control processes and quality in a more sophisticated and effective manner.

  • a first downhole tool 1202A, in this situation, is observed to experience an anomaly of some sort reflected in the data obtained from the corresponding well instrument 1204A.
  • each smart tool 1206 is configured with a machine learning application that applies a model to analyze data obtained from the well instrument 1204.
  • the machine learning application calculates one or more situation parameters that can be used to make decisions about the downhole tool 1202A, for example whether the tool is operable or not.
  • the machine learning application can be configured to update training data as new data becomes available from operation of the well instrument.
  • An updated training data set from the smart tool 1206A can be broadcast to the other smart tools 1206 in the vicinity using the Bluetooth functionality of each smart tool 1206.
  • the machine learning application in each smart tool 1206 can be configured to recompute model parameters when new training data is absorbed from another smart tool 1206.
  • the machine learning application may also include standard data set validation protocols, such as blockchain protocols or other validation protocols, to ensure that all the smart tools 1206 are using the most valid training data. In this way, processing for monitoring the operation of downhole tools can be performed locally in the field by the tools themselves, shared on a local ad hoc network, and when a central network or repository is detected by any of the tools the data and updated models can be uploaded to the repository. Until the central network or repository is available, however, the tools operate and make determinations about data and operations autonomously.

Abstract

L'invention concerne un composant de protection pour un outil de fond de trou. Le composant de protection incorpore un circuit de réseautage sans fil pour communiquer des données récupérées par l'outil de fond de trou à un référentiel de données de surface. Le composant de protection peut comprendre des capacités de traitement pour permettre au composant de protection d'être appairé à un outil de fond de trou et de configurer l'outil de fond de trou. Les capacités de traitement peuvent comprendre un traitement de données, un apprentissage automatique et des capacités de traitement de bord.
