Using distributed acoustic sensing (das) cumulative strain to relate near wellbore completions performance and far-field cross well communication

A system comprising:

• a processor;
• and
• a memory having processor-readable instructions stored therein, which, when executed by the processor, cause the processor to perform a plurality of functions, including functions to:
• acquire distributed acoustic sensing (DAS) measurements at an observation wellbore during a current stage of a stimulation treatment along a treatment wellbore within a reservoir formation;
• calculate a cumulative strain trace for the current stage of the stimulation treatment based on the acquired DAS measurements;
• determine whether to adjust a spacing of perforation clusters used at the treatment wellbore in the stimulation treatment, based on the cumulative strain trace for the current stage and a number of perforation clusters included within the current stage;
• determine whether to adjust a stage length used at the treatment wellbore in the stimulation treatment, based on a comparison between the cumulative strain trace for the current stage and a previously calculated cumulative strain trace for a previous stage of the stimulation treatment along the treatment wellbore;
• responsive to determining to adjust the spacing of the perforation clusters or to adjust the stage length, adjust at least one treatment parameter for a subsequent stage of the stimulation treatment along the treatment wellbore;
• and
• perform the subsequent stage based on the adjusted at least one treatment parameter.
