Halliburton: Hydrating Lost-Circulation Squeeze Helps Restore Circulation in Severe Loss Zone
While drilling a deep gas well through sensitive shales in the Qawassim formation in the Nile Delta area of Egypt, a major operator encountered severe lost circulation in the 8-1/2-in. intermediate interval, beginning immediately below the 9-5/8-in. casing shoe at approximately 3,100 m. Porous sand stringers are interspersed in the shale sequence, and these stringers were the suspected thief zones. The Value of Beam pumping System Automation
The need to enhance well-performance is driving the growth of well automation and optimization systems. In today's efficiency demanding business world, producers require systems that are capable of more than simply increasing the rate of production. Producers also desire the ability to decrease system failure rates consequently minimizing well down time and lifting cost by extending equipment running life, thus maximizing total system efficiency. Radar imagery offers a slick solution for locating rich reserves at sea
A thousand feet down, the ocean floor shakes. Bubbles of oil and gas burp out. In a wafting plume, the oil heads for the ocean surface where it forms a film less than a millimeter thick and many cover hundreds of square kilometers.
