What CDEUS does

CDEUS (Chaban Dependable Engineering & Unlimited Solutions) is a privately held Houston-based engineering consultancy founded in 2015 that delivers integrated multi-disciplinary services to upstream oil and gas operators. The firm is led by President and founder Fady R. Chaban, with Jesus E. Ernandez serving as Engineering Director and partner; the broader core team comprises approximately five senior practitioners with 20-25+ years of international reservoir engineering and geoscience experience spanning more than 20 countries.

CDEUS offers three interconnected service lines: Geosciences Services (basin evaluation and modeling, exploration risk analysis, seismic interpretation, petrophysics and advanced well log evaluation, geostatistics, integrated reservoir management, reservoir characterization, and geomodeling); Reservoir Engineering Services (numerical reservoir simulation, deepwater development, experimental design for EOR/IOR, heavy oil, primary/secondary/enhanced oil recovery, well test analysis, reserves and resources evaluation, decline curve analysis, and hydraulic and thermal fracture modeling); and Prospects Evaluation and Additional Services (prospect evaluation and economic analysis, field development planning, drilling/completions/operations, nodal analysis, project management, production contract management, unconventional reservoirs, and training). To broaden its solution surface, the firm maintains strategic alliances with Frontender Consulting, FlowAssure, EdataViz (hydrocarbon accounting), and DeepCast.ai (AI/data analytics).

The business model is professional-services based: project-based and retainer consulting engagements are custom-quoted per scope, with clients acquired through direct outreach via a company website, email ([email protected]), and phone (+1.832.387.7249). The firm positions itself as a senior-led boutique practice serving enterprise oil and gas clients across the Americas, Europe, and Asia, with no self-service channel, no disclosed pricing, and no public revenue or funding data.

Direct peers

• Ryder Scott Company: Houston-based petroleum reservoir engineering consultancy providing reserves evaluations, simulation, and EOR/IOR studies. Closely comparable to CDEUS in scope (reservoir engineering, reserves) and target customers (upstream E&P operators).
• Sproule: Energy consulting firm focused on reserves certification, geoscience, and reservoir engineering for upstream clients. Comparable in specialist consulting model and customer base, with stronger certification practice.
• Netherland, Sewell & Associates (NSAI): Independent oil and gas consulting firm specializing in reserves evaluation, reservoir engineering, and geosciences. Directly comparable to CDEUS in its specialist upstream consulting model and project-based delivery, though operating at much larger scale.
• Core Laboratories: Provider of reservoir rock and fluid analysis, enhanced recovery, and production services to the upstream oil and gas industry. Comparable as a specialist services firm serving reservoir-engineering workflows, though with a lab/measurement orientation.
• DeGolyer & MacNaughton: Long-established independent consultancy offering geosciences, reservoir engineering, and reserves evaluation to upstream oil and gas clients. A direct peer in integrated multi-disciplinary subsurface consulting.
• RPS Group: Energy-focused consulting firm offering subsurface, reservoir, and geoscience services to upstream operators. Comparable niche consultancy model with broader geographic reach and larger headcount.

Broad incumbents

• Halliburton: Major diversified oilfield services provider including reservoir consulting, geosciences, and drilling/completions. Comparable in upstream consulting scope but operates at significantly larger scale with global infrastructure.
• Worley: Global energy project services and consulting firm covering upstream field development planning, reservoir studies, and project management. Comparable on the field development planning and engineering consulting side for upstream oil and gas clients.
• SLB (Schlumberger): World's largest oilfield services company offering the full range of reservoir engineering, geosciences, and drilling services. Overlaps with CDEUS's integrated subsurface offering but as part of a much broader portfolio serving global E&P operators.

Emerging players

• CGG: Geoscience company providing seismic data acquisition, processing, and reservoir characterization to upstream clients. Comparable on the geosciences/interpretation side, though a larger player with proprietary data libraries.
