Holding tank monitoring system

Abstract

A holding tank monitoring system includes a sensor that is preferably located near the input of a holding tank and measures characteristics of the fluid entering the holding tank over time to predict the expected remaining production in the well.

What is claimed is: 
     
         1 . A holding tank monitoring system comprising:
 a sensor device configured to receive total dissolved solids (TDS) data of a stored fluid from a TDS sensor in real-time, wherein the TDS sensor is located near an input of a holding tank storing the stored fluid;   wherein the TDS sensor data is used to determine water production of a natural resource well; and   wherein predictive analysis is used to determine expected remaining production of the well based in part on the water production.   
     
     
         2 . The holding tank monitoring system of  claim 1 , wherein the TDS sensor is an electrical conductivity meter. 
     
     
         3 . The holding tank monitoring system of  claim 2 , wherein the electrical conductivity meter is configured to measure a salt solution percentage of the stored fluid. 
     
     
         4 . The holding tank monitoring system of  claim 1 , wherein the stored fluid is water by-product produced by a fracking well. 
     
     
         5 . The holding tank monitoring system of  claim 1 , further comprising a central server configured to receive the TDS data from the sensor device. 
     
     
         6 . The holding tank monitoring system of  claim 5 , wherein the TDS data is transmitted to the central server in real-time. 
     
     
         7 . The holding tank monitoring system of  claim 5 , wherein the TDS data is transmitted to the central server in batch format. 
     
     
         8 . The holding tank monitoring system of  claim 1 , wherein the sensor device is configured to filter the TDS data into a reduced subset of TDS data. 
     
     
         9 . The holding tank monitoring system of  claim 8 , wherein the sensor device is configured to transmit the reduced subset of TDS data to at least one of the coordinator or the central server. 
     
     
         10 . The holding tank monitoring system of  claim 9 , wherein the reduced subset of TDS data is transmitted to the at least one of the coordinator or the central server in real-time. 
     
     
         11 . The holding tank monitoring system of  claim 1 , wherein the sensor device is configured to transmit the TDS data to a coordinator, wherein the coordinator is in communication with the central server. 
     
     
         12 . The holding tank monitoring system of  claim 11 , wherein the coordinator is configured to filter the TDS data into a reduced subset of TDS data. 
     
     
         13 . The holding tank monitoring system of  claim 12 , wherein the coordinator is configured to transmit the reduced subset of TDS data to the central server. 
     
     
         14 . The holding tank monitoring system of  claim 13 , wherein the reduced subset of TDS data is transmitted to the central server in real-time. 
     
     
         15 . The holding tank monitoring system of  claim 13 , wherein the reduced subset of TDS data is transmitted to the central server in batch format. 
     
     
         16 . The holding tank monitoring system of  claim 1 , wherein the sensor device comprises:
 a controller operatively coupled to the TDS sensor, wherein the controller is configured to receive the TDS data from the TDS sensor; and   a wireless communication device coupled to the controller, wherein the wireless communication device is configured to communicate with the central server.   
     
     
         17 . The holding tank monitoring system of  claim 16 , wherein the sensor device further comprises:
 a processor in communication with the TDS sensor and the wireless communication device; and   a memory in communication with the processor and storing instructions executable by the processor for:
 receiving the TDS data from the TDS sensor; and 
 transmitting at least a portion of the TDS data to another sensor device via the wireless communication device. 
   
     
     
         18 . The holding tank monitoring system of  claims 1 - 17 , wherein the sensor device further comprises a power source for powering the sensor device. 
     
     
         19 . The holding tank monitoring system of  claim 18 , wherein the power source comprises one or more of a battery and a capacitor. 
     
     
         20 . The holding tank monitoring system of  claim 19 , wherein the power source comprises a battery, and the sensor device further comprises an energy harvester coupled to the power source for recharging the battery.
