... these subs require multiple trips downhole for mechanical or hydraulic actuation, they add rig time and costs while drilling complex, high-angle wells. This paper reviews a radio frequency identification (RFID) circulation sub that facilitates hole cleaning via remote actuation. The RFID circulation sub...

... and Ishpingo-2— were drilled in the Ishpingo field. The additional appraisal wells were planned with extended reach trajectories from existing well locations to minimize environmental impact. The logistics, drilling and testing of the two high-angle wells were operationally successful, and the geological...

... Abstract High-angle wells with longer and longer departures are being drilled at an ever-increasing pace on the North Slope of Alaska and around the world. This type well is used to penetrate new oil reservoirs and increase oil recovery in older maturing oil fields. The older maturing oil...

... ABSTRACT Recently, there has been a heightened interest in the use of horizontal wells to more efficiently drain both oil and gas reservoirs and to compensate for negative producing situations such as coning. The potential applications of horizontal and high-angle wells have led to increased...

... Abstract High-angle wells are becoming coin inon place, particularly in offshore areas. Because of this, it particularly in offshore areas. Because of this, it has become important to increase the deviation angles at which wells can be conventionally logged. Moreover, firm planning factors...
