<p>A new method has been developed for modeling acoustic monitoring of a layered-block elastic medium with several inclusions of various physical, mechanical and phase hierarchical structures. An iterative process is developed for solving the direct problem for the case of three hierarchical inclusions of l, m, s-th ranks based on the use of 2D integral-differential equations. The degree of hierarchy of inclusions is determined by the values ​​of their ranks, which can be different. Hierarchical inclusions are located in one layer: the first is anomalously dense, the second is anomalously plastic, and the third is anomalously elastic and fluid-saturated density. The degree of filling with inclusions of each rank for all three hierarchical inclusions is different. The simulation results can be used in monitoring studies of the control of fluid return from oil fields developed as part of horizontal drilling.</p><p> </p>

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.

Core Issues

Aerated underbalanced horizontal drilling technology has become the focus of the drilling industry at home and abroad, and one of the engineering core issues is the horizontal borehole cleaning. Therefore, calculating the minimum injection volume of gas and liquid accurately is essential for the construction in aerated underbalanced horizontal drilling. This paper establishes a physical model of carrying cuttings and borehole cleaning in wellbore of horizontal well and a critical transport mathematical model according to gas-liquid-solid flow mechanism and large plane dunes particle transport theory.
