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.
