System and method for identifying productive health of wells while ensuring safe operating conditions

A system comprising:

• a plurality of wells comprising an oil well, a gas well, a water injection well, a water supply well, and an observation well, wherein a first well is among the plurality of wells;
• at least one sensor disposed on or proximate the first well;
• and
• a Well Health Index (WHI) manager comprising a network controller, wherein the WHI manager is configured to:
• acquire one or more live measurements from the at least one sensor, the one or more live measurements comprising a shut-in well head pressure for the first well;
• obtain attribute data for the plurality of wells, wherein the attribute data comprises the one or more live measurements and a well type, and wherein the plurality of wells are connected to the network controller over a network;
• obtain a set of weightages;
• obtain a set of correspondences between a plurality of well types and a plurality of well attribute sets;
• generate a first Well Health Index (WHI) set for the well from a well attribute set for the well type of the first well according to the set of correspondences;
• generate attribute flags for one or more attributes in the first WHI set automatically based on the attribute data and predefined conditions for the attributes of the first WHI set;
• iteratively, until a remediation category for the first well is determined to be in good health:
• obtain a second WHI set for the well wherein the second WHI set is selected by a user by altering or confirming an attribute flag for each of the attributes in the first WHI set, wherein altering consists of either generating an attribute flag for an attribute without a flag or removing an attribute flag for an attribute with a flag, and wherein each attribute in the second WHI set is associated with a weight from the set of weightages;
• determine a sum of weightages of the second WHI set for the well by summing the weight of each attribute in the second WHI set;
• determine the remediation category among a plurality of remediation categories for the first well based on the sum of weightages, wherein each of the plurality of remediation categories correspond to a unique range of values of the sum of weightages;
• determine a remediation action for the first well based on the remediation category, wherein the remediation action is an acid stimulation procedure that enhances oil production at the first well;
• obtain an updated attribute data for the first well in response to determining the remediation action;
• update the attribute flags of the first WHI set to produce updated attribute flags automatically based on the updated attribute data;
• generate a plurality of tracking notifications and action reports for the plurality of wells based on the updated attribute flags, wherein the plurality of tracking notifications and action reports correspond to a plurality of remediation actions for the plurality of wells, and wherein the plurality of remediation actions comprise the first remediation action;
• and
• transmit, based on the updated attribute flags, the plurality of tracking notifications and action reports to at least one user device connected to the network;
• wherein the plurality of tracking notifications are repeatedly transmitted by the network controller to the at least one user device until the plurality of remediation actions are performed.

• obtaining attribute data for the plurality of wells, wherein the attribute data comprises the one or more live measurements and a well type, and wherein the plurality of wells are connected to the network controller over a network and comprise an oil well, a gas well, a water injection well, a water supply well, and an observation well;
• obtaining a set of weightages;
• obtaining a set of correspondences between a plurality of well types and a plurality of well attribute sets;
• generating a first Well Health Index (WHI) set from a well attribute set for the well type of the first well according to the set of correspondences;
• generating attribute flags for one or more attributes in the first WHI set automatically based on the attribute data and predefined conditions for the attributes of the well attribute set;
• iteratively, until a remediation category for the first well is determined to be in good health:
• obtaining a second WHI set for the well, wherein the second WHI set is selected by a user by altering or confirming an attribute flag for each of the attributes in the first WHI set, wherein altering consists of either generating an attribute flag for an attribute without a flag or removing an attribute flag for an attribute with a flag, and wherein each attribute in the second WHI set is associated with a weight from the set of weightages;
• determining a sum of weightages of the second WHI set for the well by summing the weight of each attribute in the second WHI set;
• determining the remediation category among a plurality of remediation categories for the well based on the sum of weightages, wherein each of the plurality of remediation categories correspond to a unique range of values of the sum of weightages;
• determining a remediation action for the first well based on the remediation category, wherein the remediation action is an acid stimulation procedure that enhances oil production at the first well;
• obtaining an updated attribute data for the first well in response to determining the remediation action;
• updating the attribute flags of the first WHI set to produce updated attribute flags automatically based on an updated attribute data;
• generating a plurality of tracking notifications and action reports for the plurality of wells based on the updated attribute flags, wherein the plurality of tracking notifications and action reports correspond to a plurality of remediation actions for the plurality of wells, and wherein the plurality of remediation actions comprise the first remediation action;
• and
• transmitting, based on the updated attribute flags, the plurality of tracking notifications and action reports to at least one user device connected to the network,
• wherein the plurality of tracking notifications are repeatedly transmitted by the network controller to the at least one user device until the plurality of remediation actions are performed.
