Seismic survey costs can vary by more than an order of magnitude, depending on the vendor, acquisition style and parameter selection. However, there is no guarantee that a more expensive survey delivers better data. A detailed survey design tailored to your reservoir is akin to front-end engineering. It is an essential, but often overlooked component to delivering the data your asset needs to affect your exploration, development or production decisions.
Phase-Geo provides independent, integrated survey design to meet your exploration, development and production objectives:
- Independent investigation – free of acquisition or processing company bias.
- Bespoke designs to deliver cost-effective technical success.
- Minimize environmental impact.
- Fully integrated acquisition, processing and imaging solution incorporating current and near-to-market algorithm requirements into the acquisition plan.
- Evaluation and summary of acquisition vendor solutions and capabilities.
- Rock physics and 4D feasibility.
- ‘Life of Field’ planning.
- Field trials and pre-survey tests to optimize parameters.
- Comparison of survey alternatives. (e.g. HD NAZ, MAZ, WAZ, NOAR and OBN).

Time Lapse
4D feasibility studies and intelligent survey planning are essential to ensure the success of time-lapse reservoir and/or overburden monitoring. The main objective of the analysis… READ MORE
