HOUSTON -- Baker Hughes has launched its Reservoir Navigation Services (RNS), which aims to optimize wellbore placement through reservoir modeling, a real-time drilling evaluation toolkit, and 3D/4D visualization software.
RNS includes pre-well planning to integrate multiple offset-well and digital horizon data into a 3D geospatial model of the reservoir’s anticipated stratigraphy. Proposed well plans are verified against the model’s structural data, which is then is input to Baker Hughes’ reservoir navigation software to create a predictive model of real-time tool responses to the expected stratigraphy. Additional forward models are built to test alternative geological interpretations, to qualify geological model reliability, and to identify potential weakness in the geological interpretation. Data from the various models are used to map the well in the zone of maximum interest.
During drilling operations, real-time, high-transfer rate survey and logging-while-drilling (LWD) data are captured and continuously enter into the reservoir navigation software. Customized plots present the data in its geological context on both measured and stratigraphic depth scales. Interactively linking pre-well models to a selection of geological properties allows real-time updates that accurately describe and predict the reservoir’s geology.
RNS uses a full suite of LWD tools with a size range of 4.75 to 6.75 in. (12 to 17 cm). The formation evaluation technology incorporates high-speed telemetry so data capture does not interfere with drilling time. Data interpretation and geosteering experts at the wellsite, in the client’s office, or in one of Baker Hughes’ BEACON collaboration centers, use the constantly updated geologic model and geosteering capabilities to overcome real-time drilling challenges. The continuously updated reservoir models also allow operators to further refine reserve estimates.
