... Abstract On a recent well in the Middle Bakken Dolomite, Williston Basin, North Dakota, an operator struggled to effectively geosteer a horizontal well. The geology, while usually relatively simple, proved to be more complex than anticipated. While drilling, the wellbore was steered out of zone...

To enhance reservoir understanding and optimize field recovery, advanced logging-while-drilling (LWD) services are now available for real-time acquisition and transmission of high-resolution...

... Abstract In the quest to develop shale gas reservoirs, horizontal wells have emerged as the most prolific producers with lateral sections ranging from 3,000 ft to more than 10,000 ft in length in some plays. Even with substantial experience in planning and drilling in shale, borehole stability...

... Abstract The Horn River Basin covers an estimated 3 million acres in a remote and difficult to access area of northern British Columbia. A number of Operators have experimental projects in the area, using various drilling and completion techniques, in order to evaluate the shale reservoir, gas...

... Abstract Cementing wellbores drilled in low-temperature formations such as permafrost and gas-hydrate zones requires cement compositions that set at low temperatures and yet have low heat-of-hydration. This is particularly the case for gas-hydrate zones because of the potential for gas...

... as a conventional exploration well. If it proves successful, then the prospect can be considered to be a discovery and be appraised for development. Only by drilling, completing and producing a cluster of wells in a CBM pilot test, short of proceeding directly to a partial development, are we able to locally...

... Abstract Air hammers have been used to drill gas wells in West Canada and Central USA since 1980s. Field evidence has demonstrated air drilling can be significantly improved with hammer bits in terms of Rate of Penetration (ROP), hole geometry, cost per foot, etc. However, inconsistent results...

... Abstract Successful redevelopment of the giant Whitney Canyon-Carter Creek field began in 1995, ten years after initial drilling was completed. Keys to this exploitation success were a better technical understanding of the reservoir, the evolution of completion practices and enhanced wellbore...

... Abstract To ensure continued economic success of drilling new wells in maturing gas or oil fields, it is often necessary to find methods to reduce well costs or to improve stimulation efficiency. Imperial Oil Resources applied the emerging technologies of grass-roots coiled tubing drilling...
