EngineeringNubian Nigeria Limited is an Engineering company involved in the Subsurface and Surface Engineering services in the Nigerian Oil and Gas industry.

Nubian is a leading firm of independent subsurface and surface Engineering consultant, based in the heart of the historic city of Lagos and Port Harcourt.

Our company provides essential geological, geophysical, field development plan (FDP) and facility design services for practical applications in the exploration, development and production of oil and gas in the Nigerian basins.

Established in 1986, we were one of the first indigenous company involved in providing services to the industry before the advent of the Local content drive in the industry in Nigeria today.
We pride ourselves in the services we provide our clients which cut across segment of the Exploration and Production company in Nigeria inclusive of the international Oil companies (IOC’s), the Marginal field operators and the Independents.Subsurface engineering

Sustaining our credibility earn over the years is our watch word as we provide services to our clients across board.

  • Reservoir description – a description of the reservoir architecture and associated rock and fluid properties.
  • Individual historical well performance review
  • Material balance study of the reservoirs – to estimate OOIP and relative contributions to reservoir energy from the various energy sources at play.
  • Reserves review – an estimation of the reservoir ultimate recoveries and reserves.
  • Opportunity identification – identification of possible opportunities for MRWO's, NRWO's.
  • Wellbore Utilization Plan – a plan for the short term or long term utilization of the well bore for hydrocarbon recovery.
  • Surveillance plan – Data collection and analyses critical to future decision.
  • Asset study plan – future studies for in-depth asset evaluation to mitigate uncertainties
  • Mitigation Plan – a plan to mitigate uncertainties and other possible impediments to the realization of the FCDP goals.
  • Gas Utilization – a plan to utilize all gas (AG and NAG) under "zero" gas flaring conditions
  • Abandonment Plan – a plan to abandoned all wells and other production facilities

Nubian Nigeria Limited undertakes well test design and analysis (co-ordination and interpretation of well test data) for the oil and gas industry:

  • Build-up analysis.
  • Draw down analysis.
