Abstract
AbstractHydraulic fracturing has proven success to unlock Hydrocarbon production from tight reservoirs in Petroleum development Oman for many years since 1990s. however given the high cost and extensive operation footprint, the Frac was not a favorable option in the South assets where sandstones can vary in permeability between 0.1- 4 Darcy permeability. The objective of this work to is show case Asset M organic growth in Hydraulic fracturing application and the enablers that supported this journey.Hydraulic fracturing is considered an expensive technology compared to other stimulation techniques and it requires a lot of technical work to screen the right candidates, plan and design the Frac operation. Asset M is a mix of over 20 fields ranging in size, reservoir qualities and Oil properties. This introduces additional challenge in frac candidate selection and design. To overcome these constrains the team have looked at potential techniques that could reduce the cost and accelerate the technical evaluation and frac program maturation. In this paper, the cost saving initiatives will be highlighted along with the frac design and execution simplification done. High level performance compared to baseline of each well will also be shared.The Organic growth of Hydraulic fracturing in Asset M is truly astonishing. The Asset started with 2 candidates only in 2019 to assure success and based on the outcomes, Hydraulic fracturing has been growing since with 12 wells stimulated with Hydraulic fracturing in 2022. The increase is also linked to the simplified operational approach and the high oil gain associated to these activities where in some of the wells oil gain exceeded 400%.The work presented here will be the first time to show case Asset M frac journey both from technical and commercial impact. It is a very good case study for replication across other E&P operators which are looking for more oil production beyond the easy oil gain portfolio.
