Although the microhole coiled tubing drilling rigs have been used extensively in Canada, their application in the U.S. has been very limited. In an effort to introduce this technology to the U.S. operators, GTI, with the support of DOE∕NETL, has completed a successful field testing of the coiled tubing microhole drilling technology. In this paper we report results of field testing of the system in 25 wells drilled in the Niobrara unconventional gas play of Kansas and Colorado. The objective of the field test was to measure and document the rig performance under actual drilling conditions. In these tests, a coiled tubing drilling rig (designed and built by T Gipson with Advanced Drilling Technologies Inc.) was utilized. The rig operations have continued to improve to the point where it now drills a 3100ft well in a single day. Well cost savings of approximately 30% over conventional rotary well drilling have been documented. A description of the rig and a summary of its performance in the Niobrara unconventional gas play are included. In addition, an estimate of economic advantages of widespread application of microhole drilling technology in the lower 48 states is presented.

Abstract The Oil and Gas industry has explored and developed the Lower Shaunavon formation through vertical drilling and completion technology. In 2006, previously uneconomic oil reserves in the Lower Shaunavon were unlocked through horizontal drilling and completions technologies. This success is similar to the developments seen in many other formations within the Williston Basin and Western Canadian Sedimentary Basin including Crescent Point Energy's Viewfield Bakken play in southeast Saskatchewan. In the Lower Shaunavon play, the horizontal multistage completion era began in 2006, with horizontal divisions of four to six completion stages per well that utilized ball-drop sleeves and open-hole packers. By 2010, the stage count capabilities of ball-drop systems had increased and liners with nine to 16 stages per well were being run. With an acquisition in 2009, Crescent Point Energy began operating in the Lower Shaunavon area. The acquisition was part of the company's strategy to acquire large oil-in-place resource plays. Recognizing the importance that technology brings to these plays, Crescent Point Energy has continuously developed and implemented new technology. In 2009, realizing the success of coiled tubing fractured cemented liners in the southeast Saskatchewan Viewfield Bakken play, Crescent Point Energy trialed their first cemented liners in the Lower Shaunavon formation. At the same time, technology progressed with advancements in completion strategies that were focused on fracture fluids, fracture stages, tool development, pump rates, hydraulic horsepower, environmental impact, water management, and production. In 2013, another step change in technology saw the implementation of coiled tubing activated fracture sleeves in cemented liner completions. Based on field trials and well results in Q4 2013, Crescent Point Energy committed to a full cemented liner program in the Lower Shaunavon. This paper presents the evolution of Crescent Point Energy's Lower Shaunavon resource play of southwest Saskatchewan. The benefits of current completion techniques are: reductions in water use, increased production, competitive well costs, and retained wellbore functionality for potential re-fracture and waterflooding programs.

Abstract Over the last decade productive capacity of both oil and gas from previously uneconomic North American unconventional shale resources has been dramatically enhanced due to advanced horizontal drilling technology combined with multi-stage hydraulic fracturing treatment maximizing access to productive zones. Currently two types of multi-stage fracturing completion systems are in common use: The conventional Plug-and-Perf (P-n-P) method in cased holeFrac sleeves using open hole (OH) packers or cementing to isolate multiple stages To streamline the fracturing process, a new pressure-activated toe sleeve has been developed for both methods which is run in the hole on the bottom of the completion string and actuated after two pressure applications. This sleeve isn't immediately open after the first pressure application, so casing integrity pressure testing can be conducted and pressure can also be held indefinitely to satisfy a range of regulatory requirements. As the second application of pressure is bled down, the sleeve locks open and then composite plugs for P-n-P or balls for frac sleeves can be pumped down to begin subsequent stimulation operations. This toe sleeve is especially beneficial in P-n-P completions, as an alternative to tubing conveyed perforating (TCP) to initiate pump-down operations, eliminating the initial perforation run. As a result the following features and benefits can be realized: This toe sleeve is is hydraulically actuated after two separate pressure cycles applicationsEach pressure cycle application can be held indefinitely for casing integrity pressure testing to satisfy all expected regulatory requirementsThere is no restriction on the time between two pressure applicationsIt eliminates the need for TCP perforating in the first stage of a cemented P-n-P completion at the toe of wellMultiple sleeves can be installed and activated open simultaneously at the toe of the completion stringThe toe sleeve design incorporates port areas sufficient to pump the first stimulation operation, adding an additional zone to any fracturing completion The toe sleeve is fully cement compatibleThis paper will present the operational mechanisms and a case study of the use of this unique toe sleeve which adds significant operating efficiency and lowers the cost of multi-stage fracturing with valid casing integrity pressure test.
