The magnitude, severity and scale of environmental
impacts correspond to the type and nature of
stressor components. Changes in energy policies,
demands and exploration are accompanied by
significant environmental impacts that appear to
alter the life cycle of people resident at or near
specified ground zeros.
Oil spill, for instance, has profoundly decimated
lands, water and resources, destroyed lives and
dreams, and derided creation and creativity. Unaware of well-defined
environmental signatures that mirror corresponding energy attitudes, stakeholders
and scientists have over the years lumped semi-classified impacts into a redundant
domain in the cause and effect hypothesis.
This lecture unbundles thelump, identifies clear-cut indicative footprints and aligns
them with varying energy regimes within a bounded territory. It is theorized that the
recognition of the signatures associated with contrasting energy schemes will aid
the cleaner prediction and mitigation of potential future impacts.
This novel model, in addition to securing lives and resources, will alsopropel the
development of our world in a smart and sustainable pattern.
On account of the relative ease of access to geological
exposures on the Earth surface, the critical elements
of a hydrocarbon system such as trap, source,
reservoir and seal rocks, commonly complete in the
subsurface, can be simulated on outcrop, even if as
discrete components. Sedimentological field studies
yield sets of data onstratigraphic sections and bed
geometries, macroscopic textures, fabrics, mineral
constituents, sedimentary structures, and tectonic
configurations from which features the depositional
environments can be diagnosed and the paleogeographic models formulated. In
particular, reservoir attributes documented in the field and supplemented with
laboratory analytical data, enable conceptualisation of the fluid dynamics within this
highly compartmentalized containment component of the trapping configuration.
The recognition of the equivalencies between the outcropping elements and their
subsurface counterparts facilitate insight into the upstream (exploration and
production) aspects of the petroleum industry through field and laboratory studies
carried out at a minimum cost in a non-industrial setting, but of great help in
assessing the technical risks and improving the accuracy of subsurface
interpretations. This approach is recommended for exploring the Nigerian inland
basins where outcropping lithologies and tectonic structures should constitute
pointers to prospective hydrocarbon plays in the presently inaccessible subsurface.

BENIN CHAPTER
Every discipline has been impacted over the years by
technological advancements and geoscience is not an
exception. New blue-chip startups emerge almost daily –
disrupting existing norms and initialing others. Business
owners have to adapt to new visions or align with
technology trends to remain afloat. The difference between
success and failure now has more to do with the extent to
which business executives exhibit technological insight and
foresight. E&P organizations therefore continue to hustle
and juggle in the highly dynamic market space not just to
avoid going sublime but to maximize revenue and optimize
their use of limited resources to efficiently exploit available
All these therefore come with new demands on the workforce. In this side of the world, a good
grade out of high school is no longer enough. Employers demand resources who can add value
from day one. There is the “added advantage syndrome”in the labour market and those who are
able to prove that they have been in vectorial concordance with digital transformational trends
tend to be the ones that ride these waves successfully and many grow to be captains of
organizations and industries.
As E&P organizations are looking for how to get affordable, reliable, sustainable energy; and
how to do so efficiently; as considerations for carbon capture and green energy are on the rise,
the focus turns to the geoscientist to provide for these global needs.
The geoscientist must therefore be prepared to face the challenges ahead. This presentation
exudes the salient demands and knowledge domains digital transformation has introduced and
profferssolutions on how the geoscientist may be better prepared to meet the current demands
and the challenges ahead. Participants will learn from assorted examples on the application of
trending technologies: artificial intelligence, machine learning, and data analytics in the
geoscience domain. They will be informed on basic skills required to move with technological
trends and be the geoscientist who are sought after in this digital age.
Approximately 31% non-productive time while drilling for oil
and gas in non-salt well have been attributed to geomechanics
(Dodson et al. 2009).Drilling campaign in Niger Delta has been
characterized by instability challenges such as differential
sticking/stuck pipe, hole-collapse/pack-off, lost circulation,
well ballooning, kicks, etc.
According to James Dodson survey in 2007, the oil and gas
industry loses approximately 8 billion US dollar on yearly to
problems associated with wellbore instability. Drilling process
involves the removal of rock materials that once supported the
insitu stress along the borehole trajectory, leaving the rock surrounding the hole to take the load
previously taken by the removed rock. This causes concentration of stresses around the
wellbore and often exceed the rock strength, therefore requires enough drilling fluid support to
avoid wellbore stability issues. Understanding of the magnitude of hoop stress along the
wellbore is critical for selecting the optimum mud weight requires to drill successfully without
instability.
Addressing this instability challenge requires detailed wellbore stability analysis of various
analogue wells, identifying why the well failed and incorporating learnings from them into
actionable plans for new drilling campaigns.
Since the discovery of oil by Shell BP at Oloibiri Nigeria in
1956, after half a century of exploration activities, there has
been recorded increase in oil and gas infrastructure attacks
and oil-related criminal violence. All these are classified as
outdoor crimes with its attendant exposures and have
increased the flow of illegal crude, as such affected the
flagging oil production in the country. The perceived rise in the
dynamics of organized crime and environmental damage in
the context of Nigeria's oil industry vis-a-vis the noticed
persistent lack of security of oil and gas assets triggered this
research. The exercise involves timely and adequately
securing the oil and gas-related crime scene, collection of general data (date, time and place),
geographic data (longitude, latitude, elevation, solar orientation) as well as collection of relevant
prints and spills cum pedological and ancillary data. These datasets serve as input parameters
into the proposed 'ibeneguzo' software package. The result would, among other things, present
an approximate guide to identifying the person(s) around the crime scene as at crime time and
by extension the perpetrators of such act. This software will serve as an extension and plug-in
cum add-on to the SCADA system in use which would help in providing information for
presentation of expert witness during trials. This will go a long way in vindicating the innocent
and assisting the jury in delivering effective justice.
