GeoSphere provides a unique reservoir mapping
service around the wellbore to enhance field development strategies
and to improve production
Schlumberger announced today the introduction of the GeoSphere*
reservoir mapping-while-drilling service. The new technology
reveals features in subsurface beddings and fluid contacts at the
reservoir scale to optimize well landing operations, steering
capabilities and mapping of multiple boundaries using new
deep-directional resistivity measurements enabled by proprietary
real-time interpretation techniques.
“With GeoSphere technology, Schlumberger is introducing the
first-ever reservoir mapping-while-drilling service that enables
customers to map their reservoirs using unprecedented depth of
investigation measurements around the wellbore combined with a
novel mathematical inversion methodology,” said Steve Kaufmann,
president, Drilling & Measurements, Schlumberger. ”This
long-awaited technology milestone commercialization now enables
asset teams to seamlessly integrate the data provided by the
reservoir mapping-while-drilling service with other downhole
measurements to optimize production and reservoir management.”
With a deep range of investigation that extends more than 100 ft
from the wellbore, drilling teams can use the GeoSphere service to
reduce drilling risk and accurately land wells, resulting in the
elimination of pilot holes. In addition, the real-time reservoir
mapping-while-drilling service enables the positioning of wells
within target reservoirs, away from fluid boundaries, leading to
increased reservoir exposure as well as allowing geoscientists to
refine their seismic interpretation and geological and structural
models.
The GeoSphere service has been tested in more than 140 wells
worldwide, including locations in North America, South America,
Europe, Middle East, Russia and Australia.
In the North Sea, a customer used the GeoSphere service to
successfully land a well and detect the top of the reservoir target
from a distance of nearly 50 ft, allowing for optimization of the
drilling plan before the formation was drilled. With the drill bit
over 300 ft away from the target reservoir, the
mapping-while-drilling technology confirmed that there was
considerable distance for adjusting the trajectory if needed, to
optimize reservoir entry.
Offshore Brazil, a customer deployed GeoSphere technology to
accurately map multiple deepwater-well reservoir sections. The
reservoir mapping-while-drilling service was used to guide well
steering decisions, which enabled the customer to improve the drain
position, avoid unplanned exits from target reservoirs, and to
acquire reservoir knowledge to optimize production.
In Northern Europe, a customer used the GeoSphere service to
double the reservoir net-to-gross ratio from 0.45 to 0.96 on two
horizontal wells with complex geologies. The increased exposure in
this thin bed discontinuous reservoir, compared to all previous
wells in the field, resulted in a production improvement in both
wells of more than 8,000 additional bbl/day.
