When water and sediment levels in crude oil rise beyond acceptable limits at an export terminal, the problem quickly moves beyond laboratory measurements. Product quality, processing capacity and the commercial value of an entire cargo can be affected.

At Shell’s Bonny Oil and Gas Terminal in Nigeria, such a problem became the focus of an engineering intervention involving chemical engineer Akeem Akinkunmi Akintola. Years later, aspects of the process-control approach associated with that intervention would surface at another Nigerian oilfield. A similar emphasis on controlling process variation would also appear in Akintola’s work on offshore production and semiconductor manufacturing in the United States. More recently, employment records show that the same technical trajectory has expanded into advanced materials, environmental remediation, corrosion control and nanotechnology applications.

Technical and employment records reviewed for this article provide an opportunity to follow that progression through identifiable engineering responsibilities and measurable operating results rather than professional titles alone.

The Bonny crude-quality problem

Basic Sediment and Water, commonly called BS&W, measures the water and solid material present in crude oil. Keeping that figure within specification is critical at an export terminal. Excessive BS&W can reduce crude quality, complicate processing and create the possibility of reprocessing, delays or rejected cargoes.

Records concerning operations at the Bonny terminal show that BS&W had risen to approximately 2.54 percent when Akintola became involved in efforts to stabilize the process. The engineering response focused on the conditions governing crude-water separation, including demulsification, chemical treatment and other operating variables affecting separation efficiency.

Within approximately six weeks, records show BS&W declining from 2.54 percent to 0.20 percent. The same documentation associates the intervention with a 32 percent improvement in throughput and estimates that restoring crude quality avoided more than $80 million in potential losses. Those figures describe what happened at Bonny. A later development provides a different test of the engineering method itself.

A method travels to another field

Sunday Ezekiel, now Senior Field Operations Supervisor at Renaissance Africa Energy’s Afam Field, was not part of Akintola’s original Bonny intervention. His experience with the methodology came later.

Ezekiel says process-control procedures originating from Akintola’s work were circulated within Shell operations and that he subsequently adapted the BS&W-control approach to operating conditions at Afam.

The results he reports are measurable. BS&W in Afam’s multiphase separators declined from approximately 1.85 percent to 0.34 percent within five months. Ezekiel estimates that the improvement helped the operation avoid approximately $6.2 million annually in reprocessing and downtime costs.

The significance of the Afam experience lies in the separation between the two projects. Ezekiel did not help develop the original Bonny intervention. He encountered the resulting methodology later and applied it to a different operating environment.

That makes the Afam results evidence not simply of what happened under Akintola’s direct involvement, but of whether the underlying approach remained useful after leaving the project where it originated.

The later application went beyond crude-water separation. At Afam, an approach to biologically influenced corrosion control associated with Akintola’s work was adapted to problems involving sulfate-reducing bacteria in aging process equipment.

Ezekiel reports that the program was associated with a 32 percent increase in equipment life expectancy, approximately $2.9 million in annual reductions in corrosion-related maintenance costs, and a 47 percent decrease in unplanned shutdowns associated with microbial-induced corrosion.

A chemical-injection audit framework was also adapted at the field. According to Ezekiel, reagent consumption declined by approximately 22 percent while operating and environmental-compliance performance improved.

Offshore, a different optimization problem

Akintola later encountered a different production problem while working with Mobil Producing Nigeria Unlimited. At the Usari FB offshore platform, the challenge involved gas lift. Gas lift introduces compressed gas into producing wells to reduce the effective density of the fluid column and improve production. But the relationship between injected gas and additional oil is not linear. Poor allocation can consume compression capacity without producing a corresponding increase in output.

The engineering challenge is therefore one of optimization. Project records identify Akintola as the technical lead on a redesign of the Usari gas-lift arrangement using production analysis and pressure-responsive injection controls. Following implementation, the records show a 63 percent increase in oil production and estimate approximately $40 million in recovered production value.

Akintola was later involved in hydrate-remediation work affecting the Abang wells. Hydrates are crystalline structures capable of forming when hydrocarbons and water encounter combinations of pressure and temperature. In offshore production systems, they can restrict or completely block flow.

Records associated with the Abang intervention report a 43 percent improvement in production uptime.

These offshore projects were technically different from the crude-quality problem at Bonny, but the underlying engineering logic was similar: determine which variables were limiting the process and redesign operating conditions around those constraints.

The same philosophy inside a semiconductor fab

That process-control philosophy later appeared in a markedly different industry. At Intel’s Ocotillo semiconductor manufacturing facility in Arizona- United States, Akintola worked on manufacturing process stability and yield. Semiconductor fabrication is highly sensitive to process variation. Small deviations can create wafer defects, manufacturing excursions and substantial yield losses.

Records associated with Akintola’s work report that defect density declined by 37 percent, excursion rates declined by 54 percent, and manufacturing yield increased from 92.0 percent to 95.2 percent. The resulting annual cost-of-quality benefit was estimated at approximately $24.8 million. One of the process sequences developed during the work was codified internally as Specification OCF-P-3172 and subsequently deployed across 14 parallel manufacturing tools. The evidence becomes more interesting outside Intel.

Neelima Sunil, an APTD Process Engineer at Micron Technology in the United States, has examined aspects of Akintola’s semiconductor process-control work from the perspective of another major chip manufacturer. Sunil, who has not served as Akintola’s supervisor or collaborator, describes applying aspects of his process-definition, risk-managed recipe-adjustment and predictive-yield approach within her own continuous-improvement work at Micron.

She identifies tighter process-control windows, reduction of excursions and predictive approaches to yield management among the principles that proved relevant to her manufacturing work.

Micron and Intel are competitors. The later use therefore differs from an employer simply extending its own internal procedure. It suggests that at least some of the engineering principles behind the original Intel work were sufficiently general to be useful in another advanced-manufacturing environment.

From process optimization to materials and environmental systems

Akintola’s subsequent engineering work shows continuity rather than a departure from that process-control foundation. Employment records from ETAA Innovative Solutions, Texas in the United States document his progression from an Engineering Associate role involving engineering documentation, modeling, technical data and compliance work to Principal Engineer, with responsibility for evaluating and designing engineering solutions, developing optimization frameworks, performing process modeling and applying design-of-experiments methodologies. The role also extended into environmental engineering, remediation systems, materials performance and process improvement.

That progression has continued into a Chemical Engineer position with DebbyKen Global Services, Maryland, United States. The company’s employment documentation describes work involving materials evaluation, corrosion-resistant nano-enabled coatings, environmental compliance and bioremediation protocols for contaminated soil and groundwater. It also identifies sustainable materials, green construction chemistry and nanotechnology among the technologies within the role’s technical scope.

The significance of those later assignments is not another set of financial figures. They show how an engineering approach initially visible in oil-production and semiconductor problems has broadened into materials and environmental systems: characterize the process, identify the controlling variables, model their interaction, test interventions against measurable outcomes and refine the system using data.

What can reasonably be concluded

Industrial performance figures need context. An avoided loss is not the same as money deposited into a company’s account. Offshore production can be influenced by reservoir behavior as well as surface engineering. Semiconductor yield can respond to several process changes occurring at the same time. Those limitations make it difficult to evaluate an engineer simply by adding financial figures attached to different projects.

A more useful measure is whether the record repeatedly connects the engineer to a defined technical problem, an identifiable intervention and a measurable operating change. Akintola’s record does that across several environments.

At Bonny, the variable was crude quality. At Usari, it was gas-lift performance. At Intel, it was manufacturing yield and process excursions. His subsequent engineering assignments have extended the same process-oriented approach into materials performance, corrosion, environmental remediation and nanotechnology.

The later experiences at Renaissance’s Afam Field and Micron add another dimension. In both cases, professionals outside the original project environment report finding elements of the methodologies useful in their own operations.

That does not establish that one engineer alone produced every subsequent outcome. It establishes something narrower and more technically meaningful: engineering methods developed in response to operating problems did not necessarily remain confined to the facilities where those problems occurred.

For process engineering, where successful solutions can become almost invisible once a system begins operating normally again, that portability may be one of the more revealing measures of impact.
