Understand Pressure and Flow
A critical element in designing a well abandonment program is assessing whether managing the virgin pressures is required. Throughout a field’s life cycle, the state of a reservoir will change. Pore pressures may become depleted or recharged – which could cause fault reactivation and the overburden may compact, and thermal changes also occur. Ikon provides well engineers a deeper understanding of critical ambient pore pressures, recharge pressures and the occurrence timescales, at both a regional and local scale.
Abandonment of wells also requires understanding the isolation of rock formations that have flow potential. Flow potential originates primarily from permeable formations and a pressure differential to other formations or the surface. A rock with low or no permeability, like shales and chalk, may also exhibit flow potential to consider. Ikon service teams will help you assess the flow potential of individual formations penetrated which creates valuable data to improve the design of well barriers.
