Unlike steam injection for heavy-oil recovery, the in-situ-combustion (ISC) process requires an extra step-namely, the initiation of the process, the so-called ignition operation. During ignition, an ISC front is generated near the air-injection well and, thereafter, this front is propagated toward production wells. Air-injection interruptions can be unintentional or intentional, including scheduled interruptions for 1 day per month for cleaning oil from air lines exiting the compressors. Regarding air-injection interruptions, one question arises: Can the process be resumed without initiating a new ignition operation? This paper attempts to provide answers to this question. The paper reviews information on 10 cases of air-injection stoppage in the field, involving well-instrumented dry ISC projects, conducted either in patterns or in a line-chive system. Most of the cases are from the Suplacu de Barcau (Romania) project, which is the world's largest ISC commercial project. The duration of air-injection interruptions ranged from a few hours to 42 days. Performance before and after interruptions is analyzed in terms of changes in air injectivity, effluent-gas composition, and oil production. To support various field observations, essential results from simulation of the dry ISC process are also included; temperature distributions during air-injection stoppage were determined analytically for a linear system and numerically for a radial system. In both cases, a specific characteristic of the temperature redistribution was noted: the move/shift of the peak temperature inside the former burned-out zone. Some additional conclusions regarding the stability of the process as a function of elapsed time since the initiation of the process were also formulated. Stability of the process was investigated for air-injection interruptions lasting up to 40 days.
