The Leman Field, Blocks 49/26, 49/27, 49/28, 53/1, 53/2, UK North Sea

Abstract

Discovered in 1966 and starting production in 1968, Leman was the second gas field to come into production in the UK sector of the North Sea and is still producing gas today. It is classified as a giant field with an estimated initial gas-in-place of 397 BCM of gas in the aeolian dune sands of the Rotliegend Group. The field extends over five blocks and is being developed by two licence groups with Shell and Amoco (now BP Amoco) being the operators

Multiphase Flow Characteristics of Heterogeneous Rocks From CO2 Storage Reservoirs in the United Kingdom

“…All four of these sandstone formations are important regional saline aquifers and have proven sealing and storage capacity in the form of major gas fields; for example, the South and North Morecambe fields in the Ormskirk formation, East Irish Sea (Bastin et al, ; Cowan & Boycott‐Brown, ; Meadows & Beach, ; Stuart, ; Stuart & Cowan, ); Esmond, Forbes, Gordon, and Hewett fields in the Bunter formation, Southern North Sea (Cooke‐Yarborough, ; Cooke‐Yarborough & Smith, ; Ketter, ); Ravenspurn, Leman, and Viking fields in the Leman formation, Southern North Sea (Hillier & Williams, ; Ketter, ; Riches, ); and Goldeneye, Blake, Cromarty, and Captain fields in the Captain sandstone formation, Northern North Sea (Argent et al, ). The Leman formation also contains two natural CO 2 accumulations, the Fizzy and Oak gas fields both of which contain 50–90% CO 2 (Pearce et al, ; Underhill et al, ), providing an analogue to CO 2 storage.…”

Use of exploration methods to repurpose and extend the life of a super basin as a carbon storage hub for the energy transition

“…section (as exemplified by the Victor and Viking fields in Figure 13). However, where the Zechstein Group evaporites are thin or absent, the structures show a greater degree of thick-skinned coupling to create larger closures (e.g., Leman and Hewett fields) (Hillier and Williams, 1991;Hillier, 2003).…”

“…In northern areas, the gas charge appears to be related to the occurrence of Cenozoic igneous dykes, which not only enable methane to escape Figure 13. A series of schematic cross sections through key hydrocarbon fields exemplifying the main structural styles and their control on the principal plays in the Anglo-Polish Super Basin (after Lambert, 1991;Brook et al, 2003a, b;Hillier, 2003;Peryt et al, 2010;Besly, 2018) from the upper Paleozoic reservoirs but also introduce contaminants (such as CO 2 and nitrogen) to closures containing Triassic reservoirs (Figure 14) (Underhill, 2009). As a result of the restricted access to charge, many Triassic closures are dry, and those that contain gas are commonly underfilled (Underhill, 2009).…”

“…Several lines of evidence exist to support this concept, assuming an adequate supply of gas from the generating kitchen. This seems likely since large fields such as Indefatigable (Pearson et al 1991) and Leman (Hillier and Williams 1991) are filled near to structural spill point.…”
