Oil Field Surface Facilities

Integrated engineering design and project management for wellpads, flow stations, processing facilities, and tank farms — built for reliability and long-term operational efficiency.

Integrated Design for Field Infrastructure

Oil field surface facilities are the critical link between the wellhead and the transmission network. HRP Infra provides complete engineering solutions for these facilities — from concept through detailed design, procurement support, and construction management — ensuring each installation is operationally optimised and fully compliant with Indian and international safety standards.

Our engineers combine process engineering, civil/structural design, piping layout, instrumentation, and electrical disciplines in a coordinated delivery model that eliminates interface gaps and accelerates project schedules.

Facility Types We Engineer

From individual wellpads to full-scale processing complexes, our expertise spans the entire surface infrastructure spectrum.

Well Pad & Wellhead Facilities

Civil layout, wellhead platform structural design, flowline headers, chemical injection systems, and electrical infrastructure for single and cluster well pads.

Flow Stations & Manifold Facilities

Test separators, production separators, manifolds, metering systems, and instrumentation design for field-level production gathering and measurement.

Oil-Water-Gas Separation Facilities

Three-phase separator sizing, heat exchanger design, dehydration units, and associated process engineering to meet crude quality specifications for pipeline dispatch.

Crude Storage Terminal & Tank Farm

Above-ground storage tank design (API 650), dyke & bund engineering, floating roof systems, fire protection, and terminal metering system design.

Flare & Vent Systems

Flare system sizing, knockout drums, flare tip selection, radiation modelling, and ground-level concentration studies in line with API 521 and OISD requirements.

Produced Water Treatment

Effluent treatment plant design for produced water, API separators, corrugated plate interceptors, and reinjection pump station engineering to meet CPCB norms.
