Systems and methods for updating hydrocarbon reservoir parameters

A computing system, comprising:

• one or more tangible, non-transitory memory;
• and
• one or more hardware processors communicably coupled to the one or more tangible, non-transitory memory and configured to execute instructions stored on the memory to perform operations comprising:
• identifying well data associated with a plurality of wells formed in one or more subterranean formations of a hydrocarbon reservoir, the well data comprising at least one recorded wellbore pressure associated with each well in the plurality of wells;
• determining a data density value for each well of the plurality of wells, where the data density value comprises a number of time windows in which the well has a recorded wellbore pressure;
• determining at least one well of the plurality of wells that has a data density value less than a threshold value;
• removing the determined at least one well from the plurality of wells;
• assigning each well of the plurality of wells into a pressure grouping of a plurality of pressure groupings based on a wellbore pressure similarity of the well relative to an initial pattern well that is defined by a maximum data density value, wherein the operation of assigning comprises:
• determining for each removed well, a differential between the recorded pressure data of the removed well and a pressure of each of the plurality of pressure groupings;
• and
• assigning each removed well to a particular pressure grouping based on the differential between the recorded pressure data of the removed well and the pressure the particular pressure grouping being minimal;
• generating a two-dimensional (2D) model of the hydrocarbon reservoir that comprises a plurality of grid cells, each grid cell assigned one of the plurality of pressure groupings based on an assigned pressure grouping of a well of the plurality of wells that is located within or nearest the grid cell;
• converting the 2D model into a three-dimensional (3D) model of the hydrocarbon reservoir by duplicating the assigned one of the plurality of pressure groupings of each grid cell along a column of vertical grid cells;
• and
• updating at least one of a permeability or a porosity associated with a grid block of the 3D model that is assigned to each of the plurality of pressure groupings based on a history match of the one or more wells production data or pressure data.

An apparatus comprising one or more tangible, non-transitory memory configured to store instructions operable, when executed by one or more hardware processors, to cause the one or more hardware processors to perform operations comprising:
