A hydrocarbon production process comprising operating a first early stage hydrocarbon production process within a first communication domain with a first well pair, and operating a second early stage hydrocarbon production process within a second communication domain with a second well pair, such that an intermediate reservoir region including stranded bitumen becomes disposed between the first and second communication domains; wherein the first early stage hydrocarbon production process includes injecting a first production-initiating fluid via a first injection well of the first well pair into a first communication domain such that hydrocarbon material is mobilized and conducted to a first production well of the first well pair, and producing the received hydrocarbon material via the first production well; and wherein the second early stage hydrocarbon production process includes injecting a second production-initiating fluid via a second injection well of the second well pair into a second communication domain such that hydrocarbon material is mobilized and conducted to a second production well of the second well pair, and producing the received hydrocarbon material via the second production well; selecting a pre-selected zone within the reservoir, wherein the selecting is based upon temperature fall-off data within the first and second communication zones; and positioning a portion of an infill well within the pre-selected zone for receiving mobilized hydrocarbon material of at least the intermediate reservoir region and for producing the received hydrocarbon material.
