Oil: what happens when you defer or curtail production?

impacts of deferring production at oil and gas fields

…but generally we expect shut-ins and deferrals during the 2020 COVID crisis will lower effective production capacity. The Winners. Generally, super-giant Middle East carbonate reservoirs and recently completed shale wells…

Organic Rankine Cycles: the energy economics?

Organic Rankine Cycle Energy economics

…electricity. The working fluid is usually water, which boils into steam at 100ºC, and then is super-heated to 300-500ºC. Organic Rankine Cycles aim to harness mechanical energy from lower-temperature heat…
