Every well flows at exactly one rate — the point where the reservoir's ability to push fluid in balances the tubing's ability to lift it out. This live tool solves that intersection for oil or gas wells, in field or metric units, and shows you the prize from every optimisation lever. Built on real petroleum-engineering physics, not a mock-up.
The green curve is what the reservoir can deliver: rate rises as flowing bottom-hole pressure falls. Oil uses a composite Darcy–Vogel model; gas uses the backpressure deliverability equation.
The blue curve is what the tubing demands to lift fluid to surface — a hydrostatic head lightened by produced gas, plus friction that grows with rate. Its J-shape and low-rate hook are where liquid loading bites.
Where the two curves cross is the only rate the well will actually flow. Move any slider and the gold marker chases the new equilibrium — and the sensitivity matrix below quantifies the upside from reducing drawdown, skin, or both.
Nodal analysis is where well optimisation begins. Our team takes it through calibrated PVT, multiphase-flow correlations, and full integrated production modelling — then links it straight to economics. Scope and price a mandate in minutes.
