Well test analyses that include the first and second derivative of pressure plotted on a semilog scale can help detect radial flow. Plots of pressure data from short transient tests often fail to ...

A new surface well-testing (SWT) method can help operators determine both a reservoir’s potential and when it will become uneconomical and require pressure maintenance. The Cenozoic Niger Delta ...

Offshore well testing verifies well productivity, reservoir deliverability, and fluid properties under controlled flow/shut-in conditions before full-field development or completion. It sits between ...
