Dauda Onimisi Zubairu

Principal Process Engineer
13th Floor, Heritage Place No.21 Lugard Avenue, Ikoyi , Lagos State, Nigeria.,Portharcourt

Summary

Summary

I joined Heritage Energy Operational Services Limited (HEOSL) as a Principal process engineer in October 2019 to lead the process engineering team.

My duties includes provision of leadership and integration for the surface facilities scope delivery where tight schedules and cost control is a critical success factor, process operational optimization & support, brown field modifications, green field development, feasibility &conceptual studies, facility capacity evaluation, and project execution & commissioning support.

Previously, I worked as a Senior process engineer with Motak investment limited and was deployed to Shell Petroleum Development Company Port Harcourt to handle the process deliverables of Assa North / Ohaji South Gas plant detailed design project.

Prior to joining the Assa North Team , I was Lead Front Development / Concept Engineer with Brunei Shell Petroleum for 7 years. I was Lead Front Development / Concept Engineer with Brunei Shell Petroleum for 7 years. I was responsible for all surface facility development / upgrade requirements for infill development and Well tie-in projects in the west offshore (AMPA) and Land (Darat) Asset.

Achievements:

  • Conceived and designed a water treatment system to save the company about $15million annually
  • Redesigned well casing blowdown process to avert regulatory sanctions.
  • Save over $300k for every infill development project by the development of a fit for purpose scoping template.
  • Unlocked over 5700km3 of gas and 1million m3 of oil by exploring and adoption of low cost pressure protection system
  • Reduced basis for design process from 6months to a maximum of 8 weeks. This improvements earned my team the managing director business improvement Gold award.
  • Piloted a risk based closed in tubing head pressure (CITHP) design for infill development wells geared to save 40% of facility modification cost.
  • Initiated some cross functional improvement for hydrate and low temperature brittle fracture management.
  • Initiate , conceptualize and the delivery of the process engineering aspects of frontend engineering design (FEED) packages for Soku condensate spiking project (very sensitive project for the prevention of illegal condensate bunkering from the Soku condensate delivery line).
  • Delivered several associated gas gathering process engineering aspects of FEED (functional specification) packages within budget and ahead of schedule. This projects was geared toward the government zero flaring policy.
  • Optimization of existing facilities safe saving 30% of brownfield modification cost.

With over 10 years experience as a senior process engineer, preliminary Reservoir fluid modelling/characterization and building HYSYS / UNISM model from the reservoir to the sales, preparation of fit-for-purpose post concept selection report, feasibility reports, preliminary equipment and line sizing and other process calculations (vessel, RV, etc.).are My bread and butter. I also provide input/support for inter-discipline studies/reviews as follows: design reviews, HAZID, HAZOP, SIL (IPF) classification workshop, layout studies, constructability reviews, value engineering workshops, etc. in line with relevant international codes and standards of the industry such as API, ASME, DEP and ISO Standards.
