Significant reductions in water production, and a moderate increase in oil can be achieved if a well is placed shallow in a sand-injectite system; within an interval where sand injectites are not normally resolved on seismic data, net-to-gross (N\/G) is low (typically less than 0.1), and where stand-off to the oil-water-contact (OWC) is maximised. The low N\/G of such wells challenges the paradigm that a successful development well must have a high proportion of net sand. While the cumulative volume of oil production may be similar to a development well placed closer to an OWC in a seismically mapped drill target, the cumulative volume of water produced may be significantly reduced. In the simulations presented here a broad Kv\/Kh range was used to test gross vertical connectivity uncertainty within the sand injectite system. A sweet-spot exists around a Kv\/Kh of 0.1 \u2013 above that value water breakthrough and cut were accelerated, while below that sand injectite connectivity and water flood were choked back. Considerations should also be made as to the gross architecture and flow potential of both seismically mapped, and non-seismically resolved sand injectites. Scenarios may exist where lateral sweep within a seismically mapped sand injectite is enhanced due to reduced vertical connectivity within the non-seismically resolved sand injectites.<\/jats:p>","DOI":"10.1144\/petgeo2025-113","type":"journal-article","created":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T11:19:10Z","timestamp":1769512750000},"update-policy":"https:\/\/doi.org\/10.1144\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimisation of hydrocarbon production from sand injectite systems \u2013 some rules of thumb"],"prefix":"10.1144","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8654-2887","authenticated-orcid":true,"given":"Matthew J.","family":"Brettle","sequence":"first","affiliation":[{"name":"The Sand Injection Research Group, Department of Geology and Geophysics, University of Aberdeen, King's College","place":["Aberdeen"]}]}],"member":"1881","published-online":{"date-parts":[[2026,1,27]]},"container-title":["Petroleum Geoscience"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.lyellcollection.org\/doi\/pdf\/10.1144\/petgeo2025-113","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,28]],"date-time":"2026-01-28T14:48:51Z","timestamp":1769611731000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.lyellcollection.org\/doi\/10.1144\/petgeo2025-113"},"secondary":[{"URL":"https:\/\/pubs.geoscienceworld.org\/pg\/article\/doi\/10.1144\/petgeo2025-113\/725247\/optimisation-of-hydrocarbon-production-from-sand","label":"geoscienceworld"}]},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,27]]},"references-count":0,"alternative-id":["10.1144\/petgeo2025-113"],"URL":"https:\/\/doi.org\/10.1144\/petgeo2025-113","relation":{},"ISSN":["1354-0793","2041-496X"],"issn-type":[{"value":"1354-0793","type":"print"},{"value":"2041-496X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,27]]},"assertion":[{"value":"2025-10-29","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-01-15","order":1,"name":"revised","label":"Revised","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-01-18","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-01-27","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"petgeo2025-113"}}
