National Oil Companies (NOCs) have increased their global ownership to cover 78% of worldwide oil and gas reserves. We show that this has had observable consequences on the relative market value of competitor groupings. Ownership changes are linked with corresponding changes in corporate value...

Russia's capability of meeting Europe's oil and gas (Oamp;G) demand has coincided with the Duma's stated objective of consolidating political control over strategic assets. Our sector study of strategic asset acquisitions by Russian Oamp;G companies for the period 2000-2006 analyses the relative...

Despite a trend toward asset privatization, host governments are retaining ownership over strategically important domestic oil and gas resources, effectively limiting corporate foreign direct investment (FDI). These findings are supported by an analysis of global reserve acquisitions for the...

Evidence is provided of the effects of international diversification on global asset ownership and control. We show that international geographic diversification in the oil and gas sector comes at an important cost, lower control over foreign oilfield assets relative to domestic assets (and...

We investigate the impact of oilfield control on firm value (measured as Tobin's q). The valuation effect of control over associated and subsidiary entity assets is well formulated. Less clear is the value of control when the contracting nexus is the asset itself. In this study of strategic oil...

This study focuses on the sustainable advantage of National Oil Companies (NOCs) in the global oil and gas resource sector. Specifically we examine ownership attributes, demonstrating that NOCs have increased ownership over strategic global reserves by 6%, from 72% (in 2005) to 78% in 2008. This...

We provide evidence that international diversification in the oil and gas sector comes at an important cost; lower control over foreign oilfield assets (and therefore reduced control over oilfield cash-flows). This work examines the factors that drive companies to diversify despite the loss of...
