Extending Field Life

Find Near and In-field Reserves

Leveraging the rich knowledge gained from in-field and near-field well data, combined with advanced facies-based inversion can deliver step changes in facies imaging, leading to the identification of additional hydrocarbon reserves. The first image shows dramatic improvement in detection of gas pay (red) as well as additional opportunities not identified by conventional model-based inversion in the second image.

Find Near and In-field Reserves

Producing additional near and in-field hydrocarbons using existing infrastructure brings volumes onstream faster and is more cost-effective than new field development. This approach adds reserves and extends the production lifetime, enabling the tail of a field’s base production to be realized. Seismic data can add significant value in the process. Ikon Science helps customers better understand what can be extracted from the data and how rocks behave before, during and after production activities, and how these results impact operational capabilities later in field life. Where seismic data is deemed useful for reservoir surveillance, our ability to extract fine detail and uncertainties is extremely beneficial for hydrocarbon volume assessment.

Improve Placement and Productivity

Hydrocarbon distributions derived from facies-based inversion of seismic and consistent with the exploration and appraisal wells drilled in this North Sea reservoir. Multiple scenarios, including these shown, provided a spread of gross rock volumes (GRVs) that are used by the reservoir engineer to constrain the subsurface property model used for field development planning and flow simulation.

Improve Placement and Productivity

Well placement is a major determinant of plateau production and recovery rates. During field appraisal and development, operators must understand the subsurface reservoir connectivity and flow characteristics, the potential volume of rock/drainage radius impacted during hydraulic stimulation and how these relate to each well’s projected EUR and optimum well spacing. Ikon provides integrated knowledge management across varied datasets with scenario analysis to help customers better understand risk and uncertainty. Ikon’s solution addresses critical factors such as in-situ and post-production stress states, formation strengths and more that impact well design, drilling efficiency, pressure maintenance, well performance and ultimate field productivity. The result, better well placement.

Apply EOR to Improve Recovery

4D seismic anomalies derived in PP time (left) and PS time (right). A 4D thermo-poro-elastic model was developed to match predictions and establish a relationship between time strain and temperature, which was later used to understand and predict well bore integrity.

Apply EOR to Improve Recovery

Tertiary or EOR techniques are widely used to push recovery rates ‘to the technical limit’. However, in many reservoirs a significant gap remains to achieve that potential. Before investing in a full project implementation, Ikon helps customers run cost effective feasibility studies to demonstrate the potential benefits of EOR. Ikon’s solutions explore the physical characteristics of differing EOR techniques. Models should consider fluid flow, wettability and irreducible saturation but should also include the ability to monitor in 4D, the subsurface distributions of perturbed rock-fluid volumes. The lowest-cost improved oil recovery (IOR) is often through improving the traditional waterflood, or the more novel WAG injection or gas blow down. Ikon helps our customers manage both through thorough 4D reservoir characterization and modeling. Through rigorous modeling and analysis of the petrophysical, elastic and geomechanical impact of different EOR methods, operators can better plan for and monitor the outcomes, leading to improved decision making and improved recovery.

Move to 4D Reservoir Surveillance

3D perspective a facies-based inversion (front fence section), 4D inversion for saturation and pressure (red), geomodel change in saturation and simulator porosity. The rapid combination of these properties in both 2D and 3D displays allows geoscientists and engineers to adjust reservoir model static properties and update flow simulations to match the acquired data.

Move to 4D Reservoir Surveillance

Time-lapse seismic monitoring has significant potential to impact reservoir management and to optimize life-of-field depletion planning. Ikon has a dedicated team of experts with decades of experience in 4D data processing, rock physics modeling and 4D time lapse seismic analysis and inversion to help our customers every step of the way. The first step is to perform feasibility studies with 4D rock physics models that integrate logs, core and laboratory measurements. These models can then be combined with 3D static and dynamic property models to estimate the presence, magnitude and timing of seismically detectable changes in subsurface properties.
