CHAPTER TECHNICAL SESSIONS
This work attempts to define the continent –ocean
crustal boundary (COB) offshore the Niger delta
(southeast sector) using aeromagnetic data.The
o
study area is located within longitude 6-8 E, and
o 2
latitude 3-5 N and is about 50, 625 km .The delta
formed following the Mesozoic rifting of the Atlantic
and has a total stratal thickness of about 12 km
overlying the basement.These consist of
continental, parrallic and marine Formations. The
total intensity magnetic data over the study area
th
were subjected to reduction to pole and 4 degree polynomial filtering. These
generated magnetic stripes (seafloor spreading anomalies)and deep seated
basement magnetic signatures respectively.
An isometric projection of the total intensity magnetic anomaly map of the area was
also produced. Based on distinct magnetic signatures from the three data sets, over
onshore and offshore zones, the continental crust (granitic), transitional zone and
oceanic crust (basaltic) in the study area are mapped. COB delimitation is of
profound importance in determining limits of hydrocarbon generation zones in
offshore basins.
The more the granitic crust advances seaward the higher the hydrocarbon
generation potential of the basin. From this work the COB is delimited to be circa 70
km in the west, and 100 km in the east from the coast line of the data.

The importance of rock property prediction using
seismic data can never be over emphasis. With
the advent of Deep Learning approaches, the task
of finding patterns over seismic data becomes
feasible, enabling geoscientists to execute their
prediction with very confident results. A deep
learning approach capable of training well data
and applying on the entire seismic volume, looking
at patterns on the dataset, instead of modelling a
seismic trace is the next step on any rock property
is the core of this approach.
Carbon dioxide (CO 2) in the atmosphere has
increased dramatically and faster than any time
reported in history. The storage of large volumes of
CO 2 in deep geological formations is one of the most
promising climate mitigation options. The long-term
retention time and environmental safety of the CO 2
storage are defined by the interaction of the injected
CO 2 with the reservoir fluids and rocks. Finding a

thermodynamically stable and environmentally
Storage of CO 2 as solid carbonates in basaltic rocks may provide such a long-term
and thermodynamically stable solution. Mineral carbonation in basaltic rock offers a
permanent storage solution to mitigate anthropogenic CO 2 emissions in the
atmosphere. Basaltic rocks, consisting of magnesium and calcium silicate minerals,
provide alkaline earth metals necessary to form solid carbonates.
The CarbFix CO 2 pilot project in Iceland and Wallula project, USA have shown great
potential for CO 2 storage. However, accessing the integrity of any basaltic reservoir
for permanent storage is of great importance in every CO 2 storage site.
Flow assurance in oil and gas production
encompasses the thermal-hydraulic design
a n d a s s e s s m e n t o f m u l t i p h a s e
production/transport systems as well as
prediction, prevention, and remediation of flow
constraints due to pressure drop, hydrates
formation, wax precipitation, and asphaltenes
sedimentation. Given the boundary conditions
at the wellhead, severaldeliverables such as
pipeline sizing,heat transfer, multiphase flow regimes, erosion, and
corrosion predictions are deployed to ensure that the fluid produced from
the reservoir is delivered successfully at the point of sales.
However, the flow assurance gains are often reversed in the intermediary
host facilities such as crude oil storage tanks where pressure declines,
temperature fluctuates; asphaltenic and paraffinic components of the
crude oil, water-in-oil, and oil-in-water emulsions create suitable
conditions for sludge deposition.
This presentation provides an integrated approach to multiphase flow
problems, including storage facilities using an experimental method and
computational fluid dynamics to investigate the impact of hydrodynamics
in the storage facilities in preventing sludge deposition; a promising
approach that is proven to significantly improve profit margins in oil
production.
Exploration and Production (E&P) data
management approach has been dynamic,
evolving from a side-lined process for
interpreters, drilling and reservoir engineers to a
business focal point in the asset-based,
multidisciplinary team approach to reservoir
development. Some challenges associated with
proper date management in our industry may
include data fidelity/ preservation / access/
integration/ analytics/ etc. And the salient
questions to these challenges may include but not limited to, what solutions
exist to address the issues? What frameworks and practices are emerging?
what can be done to optimize existing workflows and get fit for the future? Etc.
These and many other answers will be provided in this presentation for a better
understanding of data management solutions in the industry. Furthermore, the
presentation will discuss the trending data management activities in the oil and
gas industry. The enhancers and inhibitors, the gains and pains, the ways and
means of getting aligned with the trend, and so on. Cloud solutions and
emerging platforms, standards, and regulations with regards to E&P data are
also highlighted.
Like every other practice and discipline, data management in the E&P industry
has gone beyond the norms of yester years. If an E&P organization must
succeed, it has to look closely at its past and existing methodologies of data
management to ensure it aligns with current trends and future requirements. A
lot of organizations are now looking at, not just how their data gets managed but
who (with what skill sets) is managing it. The reasons are not farfetched,
organizations want to derive insight from their historical and acquired data as
fast as possible. Managing data in this era of Big Data requires new computing
methodologies, new hosting solutions, new plugins for enhancement and
state-of-the-art disaster recovery solutions. E&P organizations desire to be as
agile as the blue chips. A downtime of just a minute could lead to unimaginable
values of NPT for larger organizations and this could directly or indirectly affect
bottom line and profitability of the organization.
