... that drilling to Total Depth (TD) can be done without anticipating problems due to loss circulation. Often the losses start suddenly and at rates considered as total losses. It is suspected that formations causing the problem are depleted sandstone formations: Based on the indications, it seems...

... (LAM) and pumping seawater through the annulus when total losses were encountered. Though drilling was successful in this hostile carbonate environment, the main objective to obtain pressure measurements suitable for gradient analysis in open-hole environment at balance condition has raised...

... was successfully drilled by relying on conventional lost circulation material (LCM) to minimize the losses encountered. However, after drilling a pilot hole, plugging back and sidetracking the second gas well, total losses were encountered, followed by the persistent migration of gas up the annulus despite...
