Surface Manifold
CDI OIL & GAS supplies high-pressure surface manifold systems for pressure control, flow diversion, and fluid handling during well testing, drilling, and completion operations, configurable with choke manifolds, kill manifolds, test manifolds, sand separators, and flowline systems based on operating pressure, temperature, and service conditions, with options for fixed or adjustable chokes, manual or remote control, and skid-mounted configurations.

Surface Manifold System Applications Across the Well Lifecycle
Engineered to provide precise pressure control, reliable flow routing, and fast-track MRO support from initial drilling through long-term field production.
1. Drilling Operations & Well Control
Primary Function: Manages high-pressure returns, supports managed pressure drilling (MPD), and routes kicked fluids safely to blowout preventer (BOP) systems and choke/kill lines.
Skid & MRO Scope: Complete Choke & Kill Manifold skids; rapid-replacement API 16C drilling chokes, hardfaced erosion nipples, and high-pressure union spools.
2. Well Completion & Pressure Testing
Primary Function: Handles completion fluid circulation, cement displacement, casing pressure testing, and temporary surface routing prior to tree installation.
Skid & MRO Scope: High-pressure testing manifolds; replacement gate valve repair kits, stem packings, and companion flange assemblies.
3. Well Testing & Flowback Operations
Primary Function: Safely diverts high-rate hydrocarbons, solids, and frac fluids during exploration and flowback testing to separators and flare stacks.
Skid & MRO Scope: Mobile skid-mounted well testing manifolds; high-wear tungsten carbide choke trims, nozzle beans, and erosion buffer tees.
4. Early Production Facilities (EPF)
Primary Function: Enables fast-track production setup, pressure balancing, and flexible flow switching between temporary processing units and storage tanks.
Skid & MRO Scope: Modular production switching manifolds; manual/actuated gate valves, check valves, and manifold branch headers.
5. Well Intervention & Workover
Primary Function: Directs pumping fluids, isolates surface pressure, and manages chemical acidizing or kill fluid circulation during intervention jobs.
Skid & MRO Scope: Portable workover manifolds; plug valves, emergency shut-off valves, and hydraulic control console replacements.
6. Long-Term Production & Field Maintenance
Primary Function: Sustains long-term production flow distribution, allows maintenance bypass without well shutdown, and optimizes reservoir drawdown.
Skid & MRO Scope: Permanent oil/gas manifold assemblies; long-term OEM-interchangeable replacement valves, seat/gate sets, and stainless steel gauge/sensor packages.
