A wellhead platform is an offshore structure designed to support drilling and production operations, providing a stable base for wellheads, flowlines, and associated equipment.

The design considers water depth, environmental loads, well count, production capacity, and structural integrity to ensure safe and efficient operations.

Fixed platforms are secured to the seabed with piles, whereas floating platforms (such as TLPs or spars) are moored and used in deeper waters.

A marginal field is a small or technically challenging oil or gas field that may not be economically viable under standard development approaches.

Marginal fields are developed using cost-effective solutions like tie-backs to existing infrastructure, modular platforms, or mobile offshore production units (MOPUs).

Challenges include high development costs, reservoir uncertainty, infrastructure availability, and regulatory approvals.

ZEEPod is a modular offshore platform designed for quick installation, relocation, and cost-effective field development.

It provides rapid deployment, reduced installation costs, minimal seabed impact, and flexibility for relocation to different fields.

It is designed for modular disassembly and transport using barges or heavy-lift vessels.

A processing unit handles crude oil, natural gas, or produced water separation, conditioning, and treatment before further transportation or refining.

Key factors include feed composition, production rates, space constraints, safety regulations, and environmental considerations.

Modular processing units allow for faster deployment, scalability, and cost efficiency in remote or offshore locations.

EPS is a temporary production setup that allows early monetization of hydrocarbon reserves before full-scale field development.

An EPS typically includes separators, storage tanks, flowlines, and sometimes a mobile processing facility like an FPSO or MOPU.

Benefits include early revenue generation, reduced CAPEX, and flexibility to assess reservoir performance before final investment decisions.

A gas gathering station collects natural gas from multiple wells, processes it to remove impurities, and prepares it for transportation.

It includes inlet manifolds, separators, compressors, dehydration units, and metering systems.

It optimizes gas collection, reduces flaring, and enables efficient transportation to processing plants or pipelines.

A MOPU is a floating offshore production facility that can be quickly deployed and relocated for marginal field development.

MOPUs are typically converted jack-ups or semi-submersibles used for production, while FPSOs include large storage capacities for crude oil.

It offers cost-effective and rapid deployment, flexibility for short-term projects, and reduced decommissioning costs.

An FPSO is a floating vessel used for offshore oil and gas production, processing, storage, and offloading.

FPSOs eliminate the need for fixed platforms, reduce infrastructure costs, and provide mobility for redeployment.

Challenges include hull integrity, mooring system reliability, and managing topside processing complexity.

Pipelines include subsea, onshore, and export pipelines for transporting crude oil, natural gas, or refined products.

Key factors include operating pressure, material selection, corrosion protection, and environmental conditions.

Methods include S-lay, J-lay, and reel-lay techniques, depending on water depth and pipeline specifications.
