The current document is directed to automated reinforcement-learning-based application managers that that are trained using adversarial training. During adversarial training, potentially disadvantageous next actions are selected for issuance by an automated reinforcement-learning-based application manager at a lower frequency than selection of next actions, according to a policy that is learned to provide optimal or near-optimal control over a computing environment that includes one or more applications controlled by the automated reinforcement-learning-based application manager. By selecting disadvantageous actions, the automated reinforcement-learning-based application manager is forced to explore a much larger subset of the system-state space during training, so that, upon completion of training, the automated reinforcement-learning-based application manager has learned a more robust and complete optimal or near-optimal control policy than had the automated reinforcement-learning-based application manager been trained by simulators or using management actions and computing-environment responses recorded during previous controlled operation of a computing-environment. |

If a security error is identified in the existing software, then security of the existing software is improved by labeling a session ID in a session workflow as high confidentiality, such that the session ID remains only in confidential channels. Non-owner channels and authorization server channels are labeled as public channels. The session ID is type checked with a security type system, and security of the session ID is verified. |

Drilling modeling calibration, including estimation of drill string stretch and twist
This disclosure is related to real-time calibration of drilling modeling programs and to the estimation of pipe stretch to perform corrections for the inclination and azimuth measurements and the estimation of pipe twist to perform corrections to the tool face setting. A measurement tool with a plurality of sensors is disposed along the drill string. Measurements are taken continuously during the drilling process from each of the sensors to determine torque, bending moment, and axial force data. This information is iteratively coupled with a mechanical torque-drag model (based on standard mechanics of deformable materials and on wellbore mechanics) to accurately estimate stretching and twisting of the drill string in real-time or near-real-time and thereby promote accurate wellbore placement. |

Production well apparatus for underground coal gasification and use thereof
A production well apparatus for underground coal gasification and an underground coal gasification method using same. The production well apparatus comprises a well head apparatus, a sleeve (8), a product pipe (1), a coolant pipe (3), and a monitoring meter system (7). Coolant is injected, during underground coal gasification, to be in contact and mixed with product gas, and the product gas is discharged after cooled, such that the operation is safer and more controllable. Moreover, most of the components of the production well apparatus can be completely or partially recycled and reused after the gasification is completed. |

System and method for shock mitigation
A technique facilitates mitigation of shock loads. Subterranean communication systems may comprise components susceptible to various shock loads. A shock mitigation system is physically coupled with the subterranean communication system to mitigate such shock loads. The shock mitigation system comprises components selected to enable reduction of various effects of shock loads, e.g. shock loads resulting from perforating procedures, which could otherwise be detrimental to continued operation of the subterranean communication system. |

Perforating gun
A perforating gun for use in oil and gas operations. The gun is carried to a desired area of a wellbore using only fluid pressure. The gun comprises a charge housing disposed within a removable sleeve. The charge housing comprises a plurality of shaped charges in communication with one or more sensors. The sensors are programmed to initiate the detonation sequence of the shaped charges upon measuring set parameters. Upon detonation, the gun fragments into a plurality of pieces that may be washed away from the detonation site. |

Optimizing waste slurry disposal in fractured injection operations
Methods and apparatus are provided for optimizing operations for a fracturing injection waste disposal well especially where the formation is damaged or tight such that pressure fall-off tests are impractical due to extended leak-off rate times. Formation closure pressure and formation stress are calculated using Instantaneous Shut-in Pressure rather than traditional methods requiring actual fracture closure. |

Downhole welding process and tool therefore
A welding tool for welding a blanking plate within a wellbore casing downhole thereby sealing the wellbore is described. The tool comprises a tubular body of a diameter sufficiently narrow to fit in a wellbore casing, the tubular body having a downhole end and a surface end; and a welding head assembly connected to the downhole end of the tubular body. The welding head assembly comprises a connector device for retaining a blanking plate to be welded within the wellbore casing, and a welding powder container which comprises a chamber for holding the exothermic welding powder, the chamber having at least a portion extending adjacent the blanking plate to be retained and proximate the wellbore casing to which the blanking plate is to be welded when the tool is positioned downhole in the wellbore casing; and an igniter wire opening for accommodating an igniter wire extending into the chamber. |

Well or bore clearing tool
For clearing of the bore liners of geothermal wells, disclosed is a clearing tool that can be used without a drive motor, but with a drive hammer, to clear mineral deposits from the inside of the bore liners of geothermal wells. A forward end clears unwanted material from a live well. An aft end engages with a hammer device. The tool also has working surfaces to bear against and to cut through or to break up the unwanted material, at least one bypass passage conveying fluid from the live well through the clearing tool, and at least one exhaust passage communicating with the hammer device and conveying exhaust gases from the hammer to exhaust exit ports. The location of at least one exhaust exit port is a location that is situated aft of a forward face of the forward end of the clearing tool. |

Apparatus for downhole fracking and a method thereof
A downhole valve has a valve body having at least one port and slidably receiving in a longitudinal bore thereof at least a first sliding sleeve for opening and closing the at least one port. The first sliding sleeve has a circumferential actuation groove. An actuation assembly is extendable into the first sliding sleeve and has an actuation housing axially movably receiving thereon a compressible sealing element and a slip assembly. The slip assembly has one or more slips radially outwardly extendable under a hydraulic pressure for engaging the circumferential actuation groove of the first sliding sleeve for opening the at least one port, and the actuation assembly is longitudinally extendable to position a portion thereof on an inner side of the one or more slips for supporting the one or more slips at a radially outwardly extended configuration. |

Method and apparatus for filling an annulus between casing and rock in an oil or gas well
The invention relates to the decommissioning of hydrocarbon wells. It concerns the artificial promoting or inducing of creep in the overburden formation 3 surrounding an oil well 1, so that the formation rock 3 encroaches against the casing 5 to form a seal. This avoids the need to plug the annulus between the casing 5 and formation 3 with cement. The overburden may be caused to creep by reducing the pressure in the annulus, by applying heat to the overburden rock or by stressing the rock repeatedly to cause fatigue in the rock 3. |

Predetermined load release device for a jar
A release device for a jarring tool includes a collet positioned between the mandrel of the jarring tool and a trigger sleeve. At least one end of the collet is in contact with a precompressed spring via a bushing. In order for the jarring tool to operate, a force greater than the precompressed force of the spring must be applied to the mandrel so that the collet can move in axial direction against the spring thereby releasing the mandrel. |
