Driven by the need to develop a cost-effective solution
to produce from the low permeability chalk reservoirs in the Danish North Sea, Maersk Oil became
a pioneer in applying horizontal drilling techniques. Extended reach drilling
increases the effective surface area of the well and therefore maximises contact
with the reservoir.
In order to position these long reach horizontal wells optimally,
geosteering skills using biostratigraphic data, cuttings and Logging
While Drilling (LWD) data were perfected in-house. Multilateral
wells helped to further reduce the number of well slots required to
develop the fields. These skills complement Maersk Oil’s toolbox of
well completion and stimulation technologies.
During recent years new frontier areas have been added to
Maersk Oil’s portfolio, setting new challenges. These include
deepwater operations and also the ability to handle higher
pressures and temperatures than ever before.
