When it comes to geophysical monitoring of mature fields undergoing Enhanced Oil Recovery (EOR), new challenges demand new ideas. However, with a myriad of products and solutions available for reservoir monitoring, it is important to select technical solutions that increase value by either ‘illuminating’ oil that would otherwise be missed or by aiding in improving reservoir management by increasing production and/or reducing risk to infrastructure.

Petroleum Development of Oman (PDO) has over the years developed a workflow to best assess, pilot and implement such technologies. Here we share an example for a carbonate field in the North of Oman that is scheduled for full field implementation of steam injection. For this field, PDO have piloted several technologies, some of which have proven to be of value during the pilots and others that have been rejected. The feasibilities which can involve field trials have included several geophysical surveillance technologies include surface deformation through Satellite (InSAR) and GPS, micro-seismic, VSP, permanent source and receivers as well as microgravity to name a few.

Here we present some examples such as field trials and design studies done to justify full field implementation of technologies such as micro-seismic monitoring. We also show how based on some analysis results we concluded to reject 4D seismic surveillance in this case. We demonstrate how successful technologies were selected and how we hope they can aid in increasing the field’s oil recovery and create additional value.
