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 ...

Combining circumferential stresses with additional stresses produced by fluid seepage creates a new model which can be combined with the conventional model to fully describe in-situ stress regimes' ...

According to McMoRan, a piece of equipment became lodged in the wellbore while preparing the hole for tubular installation last month. Operations are continuing to remove the stuck equipment and clear ...
