ment providers and two drilling contrac-
tors to place permanent BTR MPD systems
on two drillships.

Using BTR MPD in the Gulf of Mexico
required the submission of a new tech-
nology plan to the US Bureau of Safety
and Environmental Enforcement. Adding
MPD equipment to the rigs fundamentally
changed the way some operations, such
as tripping, were performed. This neces-
sitated the creation of more than 40 new
mandatory rig-specific procedures for
each of the rigs and the development of
classroom, simulator and onsite refresher
training. Before putting a single piece of MPD
equipment on the rigs, the team conducted
a five-step review that included a hydrau-
lics check, onshore flow test, RCD durabil-
ity test, HAZID/HAZOP workshop, and a
complete logic system review of the MPD
control system.

Achieving objectives
Their careful planning paid off. Mr Vaczi
called the application of deepwater MPD
highly successful, with all wells drilled to
total depth with no losses through the high
depletion intervals or the tight margins of
the intermediate section.

“We had no major safety incidents
throughout the implementation and exe-
cution of MPD, and all systems performed
as intended.”
Compared with offset wells drilled con-
ventionally, MPD successfully reduced
equivalent circulating density (ECD) by
0.5 ppg. Dynamic pore pressure tests per-
formed on all wells enabled the team to
further reduce mud weight while remain-
ing within the safe parameters identified
by borehole stability studies conducted
prior to the startup of operations.

They also successfully ran and cement-
ed all production liners in the campaign
using MPD and reduced cementing ECDs
by almost 1 ppg compared with conven-
tional operations.

“This is critical to the success of the
cementing job in achieving zonal isolation
in these intervals,” Mr Vaczi said. DC

Workforce development goes hand in
hand with industry’s digital transformation
The digital transformation is critical to building and main-
taining the workforce of the future, so companies must enhance
their understanding of digital systems if they want to attract and
retain young talent, said Brett Schellenberg, Director of Controls
and Automation at Nabors.

In this video from the IADC Drilling Engineers Committee
(DEC) Q1 2022 Technology Forum, held in Houston on 30 March,
Mr Schellenberg discusses how the role of the driller is changing
amid the digital transformation, as well as the challenges that
drilling contractors face in an increasingly digital ecosystem.

Watch the video for more information.

Attracting young talent will require oil and
gas companies to think outside the box
The oil and gas industry is looking to new avenues to find
the workers needed in order to adapt to a changing technical
landscape, with companies rethinking the skillsets they need
to thrive in the future. Speaking from the IADC DEC Technology
Forum in Houston in March, Willie Thompson, Senior Manager,
Early Career Engineering at Hess, discusses the external and
internal forces that have changed how the industry looks for
new talent.

Mr Thompson also discusses the “attributes for today” that
companies find necessary in young workers, as well as the
ways in which Hess is investing in talent development.
