Abstract

A system includes at least one hardware processor interoperably coupled with computer memory and configured to perform operations of one or more components of the computer-implemented system. The system includes a detachable module (DM) delivery system configured to deploy, from release grooves of the NRSS and during a survey of the NRSS inside a wellbore during drilling of a well, plural DMs into an environment surrounding the NRSS, wherein the plural DMs are pre-loaded into the NRSS, and plural DMs are configured to gather and store sensing data from the environment.

First claim

What is claimed is:

1. A computer-implemented system, comprising:
a non-retrieval sensing system (NRSS) comprising:
at least one hardware processor interoperably coupled with computer memory and configured to perform operations of one or more components of the computer-implemented system; and
a detachable module (DM) delivery system configured to deploy, from release grooves of the NRSS and during a survey of the NRSS inside a wellbore during drilling of a well, plural DMs into an environment surrounding the NRSS, wherein the plural DMs are pre-loaded into the NRSS, and the DM delivery system includes a motorized release system that includes a motor encased in a housing of the NRSS, the motor configured to engage a rack to deploy the plural DMs at different intervals during the survey of the NRSS, the NRSS including a battery for powering the motor; and

plural DMs configured to gather and store sensing data from the environment.

2. The computer-implemented system of claim 1 , wherein the DM includes:
a printed circuit board including a microcontroller configured for controlling the DM, including controlling communication with the NRSS and with external systems to which the DM provides data;
storage chips for storing sensor information; and
electrodes for engaging powered contacts in the release grooves of the NRSS.

3. A computer-implemented method, comprising:
initiating a survey of a wellbore using a NRSS;
preloading plural DMs into the NRSS;
configuring the NRSS to gather and store sensing data for the wellbore;
deploying the NRSS into the wellbore;
gathering and storing environmental condition or wellbore information using NRSS;
monitoring conditions for release of the plural DMs into the wellbore;
deploying the plural DMs into the wellbore, wherein deploying the plural DMs includes using a mechanical release system that includes a spring encased in a housing of the NRSS, the spring configured to cause deployment of the plural DMs using inertial motion of the NRSS when the NRSS reaches a stopping point the survey of the NRSS;
gathering and storing environmental conditions using battery-powered ones of the plural DMs;
acquiring data from the plural DMs; and
using the acquired data for making operational decisions.

4. The computer-implemented method of claim 3 , wherein the DM includes:
a printed circuit board including a microcontroller configured for controlling the DM, including controlling communication with the NRSS and with external systems to which the DM provides data;
storage chips for storing sensor information; and
electrodes for engaging powered contacts in release grooves of the NRSS.

5. The computer-implemented method of claim 3 , wherein the NRSS includes:
locational/movement components including a 3-axis magnetometer, a 3-axis accelerometer, and a 3-axis gyroscope; and
a microcontroller configured to control the NRSS and including a timer, a central processing unit (CPU), input/output (I/O) ports, random access memory (RAM), interrupts, and read-only memory (ROM);
and wherein the microcontroller determines different intervals for deploying the plural DMs using information from at least one of the locational/movement components and the timer.
