Upstream meaning

Published by a LexisNexis Energy expert
What does Upstream mean?
In legal practice, “upstream” describes exploration and production (E&P) activities: acquiring rights to search for petroleum, conducting seismic and appraisal, drilling and field development, and producing hydrocarbons to the point of export or entry into midstream infrastructure. It is a widely used commercial and regulatory descriptor rather than a defined statutory term, appearing across contracts, regulatory guidance and transaction documents. Typical upstream documents include petroleum licences and leases, assignments and farm-out agreements, joint operating agreements (JOAs), drilling and oilfield services contracts, security and project finance instruments, and decommissioning arrangements. Key legal issues include title to petroleum in situ and on production, licensing and operational consents, environmental and health and safety compliance, subsurface data ownership, third‑party infrastructure access, and allocation of decommissioning liabilities. Usage is consistent across England & Wales, Scotland, Northern Ireland and Ireland, though authorities and regimes differ. For example, UK offshore licensing for the UK Continental Shelf (UKCS) is administered by the North Sea Transition Authority; certain onshore licensing is devolved; Northern Ireland operates a separate petroleum licensing regime; and in Ireland authorisations are granted under the Petroleum and Other Minerals Development Acts by the Minister for the Environment, Climate and Communications. Upstream is distinct from midstream (transport and storage)...

War-related force majeure in energy contracts: English law checklist on triggers, thresholds, causation, mitigation, notices, frustration and termination consequences, and drafting for future risk

Checklist Intensifying geopolitical conflict — including open hostilities, regional volatility, cyber interference and closure of sea lanes — can exert rapid, multifaceted strain on energy-sector contracts. This checklist offers a structured, practical approach to evaluating force majeure (FM) risk in an active conflict or war setting, and to judging whether FM can be effectively invoked under English law. It also maps how that assessment intersects with frustration and contractual termination rights, and sets out drafting considerations for parties to weigh in future transactions so that FM provisions expressly address war risks. It is intended for legal and commercial teams operating across oil and gas, LNG, trading, infrastructure and energy supply chains, where disruption frequently stems from direct physical impossibility at the point of delivery, or indirectly via upstream or downstream domino effects. The objective is not solely to test the viability of an FM claim, but also to enable informed, risk-aware choices in rapidly evolving conflict environments. This checklist focuses on FM arising from war-related physical and operational disruption....

EU competition round-up: AG Medina backs Commission on PKN Orlen/Lotos; AG Emiliou on sports agents rules and COVID-era no-poach pact; merger updates (15 May 2025)

Mergers AG advises Court of Justice to reject appeal against conditional Phase II clearance of the PKN/Gupto Lotos merger Advocate General Medina has delivered his opinion in Case C-541/23 P, Polwax v Commission, an appeal against the General Court’s judgment in Case T-585/20 that upheld the Commission’s 14 July 2020 decision conditionally clearing the acquisition of PKN Orlen after a Phase II investigation (M.9104). He recommends that the Court of Justice dismiss the first ground of appeal, which concerns the definition of the upstream market. Background On 14 July 2020, the Commission approved, subject to conditions, the proposed acquisition of Lotos by PKN Orlen (the Commission’s 2020 decision). Lotos and LKN Orlen were two large Polish integrated oil and gas companies. Following its Phase II review, the Commission concluded that the merger would harm competition, notably in the following areas: the wholesale and retail supply of motor fuels in Poland; the supply of jet fuel in Poland and the Czech Republic; and ...

Margin Squeeze under Article 102 TFEU: Evolution, As-efficient Competitor Test, and Case Law from Commodities to Telecoms

Margin squeeze Margin squeeze is a form of exclusionary behaviour aimed at rivals, intended to remove them or undermine their viability—either by driving them from the market or by deterring entry at the outset. Where a vertically integrated firm holds a dominant position in an upstream market for a vital input and also supplies that input to wholesale customers who compete at retail, it can have both the means and the incentive to exclude those competitors from the downstream market. The dominant firm compresses retail rivals’ margins by setting a high wholesale charge, a low retail price, or a mix of the two, thereby narrowing the gap between the cost of essential inputs and the price attainable in the retail market. Consequently, the spread between the dominant undertaking’s retail price for the product or service and the wholesale price it levies on its rivals is insufficient to allow an efficient retail rival to compete effectively. This weakening of effective competition downstream can, in turn, result in higher prices, diminished...

UK offshore upstream oil and gas insolvency and restructuring: a legal practitioner's guide to OGA licensing and consents, JOAs, decommissioning liabilities, cross-border issues, and officeholder options

Introduction to common participants in the market The oil and gas sector is a major contributor to the UK economy: It supports around 152,000 jobs, both directly and indirectly It accounted for 0.8% of GDP in Q2 2015, down from a peak of 2.5% in Q2 2008 Government revenues from production in 2016/2017 were £1.2bn The UK is Europe’s second largest oil producer and the third largest gas producer Historically, the industry has been buoyant, with limited involvement from insolvency practitioners. In 2010, there were only four insolvencies in the sector. However, when oil prices fell to a record low in 2015, the number of insolvencies increased to 28 that year. Due to its maturity, the UK continental shelf is among the more expensive regions globally for oil production: before the 2015/2016 downturn, producing a barrel in the UK cost about US$40, compared with under US$5 in Kuwait. These costs have somewhat reduced since the 2015/2016 downturn...

UKCS oil and gas asset transfers: LOGIC Master Deed—pre-emption, standardised transfer arrangements, Execution Deeds drafting, Master Deed Online and NSTA consents

The Master Deed is the standardised mechanism used across the United Kingdom Continental Shelf (UKCS) to formalise asset transfers. It is long-established and addresses two strands: (i) pre-emption, and (ii) standardised transfer arrangements. Its four principal objectives are to: bring existing pre-emption provisions into a common form provide pro-forma transfer arrangements cut complexity around document execution, and deliver greater certainty over completion timing Structure The concept is embedded in the main body of the Master Deed, but most day-to-day operative provisions sit in the schedules, arranged as follows: main body — appoints the Administrator to operate the Master Deed processes and provides for new parties to join via a Deed of Adherence schedule 1 — lists the Contracting Parties at the date of signature schedule 2 — New Transfer Arrangements — whose Annexes include the Execution Deed schedule 3 — New Pre-Emption Arrangements, and schedule 4 — Deed of Adherence ...
