TLDR
Crude oil lifting is the physical and commercial process of loading produced crude oil onto a tanker for sale or export — and in Production Sharing Contracts, it also defines how each party (government and contractor) takes their entitled share of oil from the field.

Introduction
If you work in oil and gas — or invest in energy companies — you will hear the word "lifting" constantly. It shows up in quarterly reports, PSC agreements, OPEC communiqués, and field operations briefings. Yet for many people outside the upstream industry, the term remains opaque.
Crude oil lifting is simply the act of physically loading crude oil from a production facility into a vessel for transport. But behind that simple act lies a precisely scheduled, legally governed, and commercially significant process — one that determines how billions of dollars in oil revenue are divided, measured, and settled between governments and oil companies every single month.
This article breaks it all down: what lifting is, how it works operationally, how entitlements are calculated under Production Sharing Contracts, and what happens when parties lift more — or less — than their fair share.
What Is Crude Oil Lifting?
In the oil industry, lifting refers to the transfer of custody of crude oil from a production facility — whether offshore platform, onshore gathering station, or floating storage unit — to a tanker or pipeline export system.
Think of it as the handover point: the moment crude oil leaves the producer's hands and becomes a tradable cargo. Every cargo that is lifted is assigned a Bill of Lading (B/L) — a legal document specifying the volume, quality, date, and parties involved. The B/L is the official record of that lifting event.
Lifting is distinct from production. A field may produce 100,000 barrels per day continuously, but liftings happen in discrete cargo parcels — typically every 7 to 30 days depending on field size, storage capacity, and tanker scheduling.
Key documents generated at every lifting:
- Bill of Lading (B/L) — confirms cargo volume and transfer of title
- Certificate of Quantity (COQ) — independent measurement of loaded barrels
- Certificate of Quality (CQL) — API gravity, sulfur content, BS&W, viscosity
- Notice of Readiness (NOR) — tanker's formal declaration that it is ready to load
Where Lifting Happens: The Loading Infrastructure
Crude oil is loaded through different types of infrastructure depending on whether the field is offshore or onshore.
Offshore Loading
- Single Point Mooring (SPM) / Single Buoy Mooring (SBM) — a buoy anchored offshore to which a tanker moors and loads via a flexible hose. The most common offshore loading method worldwide.
- Floating Storage and Offloading (FSO) — crude is transferred from platform to FSO vessel, then shuttle tankers lift from the FSO.
- Floating Production Storage and Offloading (FPSO) — the FPSO both produces and stores crude, with shuttle tankers lifting directly from it.
Onshore Loading
- Marine terminals and jetties — crude flows by pipeline from gathering stations or tank farms to a marine terminal where tankers berth alongside loading arms.
- Pipeline export — in some regions (e.g., trans-national pipelines), lifting takes place at a pipeline custody transfer point rather than a marine terminal.

Lifting Entitlement Under Production Sharing Contracts (PSCs)
In countries where oil is produced under Production Sharing Contracts (PSCs) — including Indonesia, Malaysia, Angola, and many others — lifting takes on a second, critical meaning: it is the mechanism through which each party takes physical delivery of their contractual share of crude oil.
Under a PSC, gross production is divided into:
- Cost Oil (Cost Recovery) — the portion of production allocated to the contractor to recover capital and operating expenditures.
- Profit Oil — the remaining production after cost recovery, split between the government (represented by the National Oil Company, e.g., Pertamina in Indonesia) and the contractor according to the PSC split ratio.
Each party's lifting entitlement is their combined share of cost oil and profit oil for a given period. This entitlement — expressed in barrels — determines how much crude each party is authorized to lift from the field.
Example: If monthly production is 1,000,000 barrels and after cost recovery the profit oil split is 70% government / 30% contractor, and the contractor's cost oil entitlement is 200,000 barrels, then:
- Contractor lifting entitlement = 200,000 (cost oil) + 240,000 (30% of 800,000 profit oil) = 440,000 barrels
- Government lifting entitlement = 560,000 barrels (70% of 800,000 profit oil)
The Lifting Schedule
Because tankers arrive in discrete windows and crude storage is finite, liftings must be planned in advance through a Lifting Schedule (also called a Parcel Schedule or Cargo Schedule).
The operator prepares the lifting schedule — typically monthly — and allocates specific cargo windows to each entitled party. Each cargo specifies:
- Laycan (Laydays Cancelling) — the window of dates during which the tanker must arrive
- Nominated volume (barrels)
- Loading terminal or buoy
- Crude grade and quality specification
Parties then nominate a tanker for their allocated window. The operator confirms the nomination, and the loading master at the terminal manages the physical operation.
Custody Transfer Measurement
Before any money changes hands, the volume and quality of lifted crude must be measured independently. This is called custody transfer measurement — arguably the most critical step in the lifting process.
Measurement is performed by an independent inspection company (such as SGS, Intertek, or Bureau Veritas) using:
- Shore tank gauging — measuring tank levels before and after loading
- Flow metering — using Coriolis or turbine meters on the loading manifold
- Ship's figures — ullage measurements taken aboard the tanker as a cross-check
The Certificate of Quantity is issued once measurement is agreed. Any significant discrepancy between shore figures and ship's figures triggers a formal dispute process.
Quality parameters measured include API gravity, sulfur content (sweet vs. sour), Reid Vapor Pressure (RVP), and Basic Sediment & Water (BS&W). These determine the crude's market price relative to the benchmark (e.g., Brent, WTI, or Dated Brent).

Over-Lifting and Under-Lifting
Because tankers come in fixed sizes (e.g., Aframax: ~700,000 barrels; Suezmax: ~1,000,000 barrels) and production is continuous, it is virtually impossible for each party to lift exactly their entitlement every month. The result is lifting imbalances.
- Over-lifting — a party lifts more barrels than their entitlement for the period.
- Under-lifting — a party lifts fewer barrels than their entitlement.
These imbalances accumulate over time and are tracked carefully. Settlement methods include:
- In-kind settlement — the over-lifted party allows the under-lifted party to take an extra cargo to balance the account.
- Cash settlement — the over-lifted party pays the under-lifted party the cash equivalent at an agreed price (typically the cargo price or a formula price).
Most PSC agreements specify the settlement mechanism and the tolerance threshold (e.g., imbalances exceeding a certain number of barrels must be settled within a defined period).
Why Lifting Matters Beyond Operations
Lifting data is not just an operational metric — it carries direct financial and strategic significance:
- Revenue recognition — oil companies recognize revenue at the point of lifting (transfer of title), not at the point of production. A delayed lifting can shift revenue between quarters.
- OPEC quota compliance — OPEC monitors member country production through export lifting data. Over-lifting relative to quota can trigger diplomatic and commercial consequences.
- Market intelligence — tanker tracking firms (e.g., Kpler, Vortexa) publish lifting data from vessel AIS signals, making it a key real-time indicator of actual supply flows.
- Investor reporting — listed oil companies report net entitlement production (i.e., their lifting entitlement under PSC), which can differ significantly from gross production and is the figure that drives earnings per barrel calculations.
Conclusion
Crude oil lifting sits at the intersection of petroleum engineering, contract law, and commodity trading. It is the physical moment when oil transforms from molecules in a reservoir into a traded cargo with a price, a title, and a destination.
Understanding how lifting works — the entitlement calculations, the scheduling process, the custody transfer measurement, and the imbalance settlements — gives you a far clearer picture of how oil revenue actually flows from wellhead to national treasury and corporate balance sheet.
Whether you are tracking an energy company's quarterly results, analyzing PSC terms, or simply trying to understand how oil markets function, lifting is a concept that connects all the pieces.
