Abstract: Embodiments of forecasting hydrocarbon production are provided. One embodiment comprises transforming production data of a plurality of training wellbores and production data of at least one target wellbore such that the production data for all training wellbores and target wellbores are equivalent at the end of a first period of time; generating a transformed production forecast for each target wellbore at a target forecast time responsive to the transformed production data; and back transforming the transformed production forecast for each target wellbore to remove the equivalency. The back transformed production forecast for each target wellbore is the final production forecast for each target wellbore.

Abstract: A method and apparatus for monitoring a structure using an optical fiber based distributed acoustic sensor (DAS) extending along the length of the structure. The DAS is able to resolve a separate acoustic signal with a spatial resolution of 1 m along the length of the fibre, and hence is able to operate with an acoustic positioning system to determine the position of the riser with the same spatial resolution. In addition, the fiber can at the same time also detect much lower frequency mechanical vibrations in the riser, for example such as resonant mode vibrations induced by movement in the surrounding medium. By using vibration detection in combination with acoustic positioning then overall structure shape monitoring can be undertaken, which is useful for vortex induced vibration (VIV) visualisation, fatigue analysis, and a variety of other advanced purposes. The structure may be a sub-sea riser.

The hydrogen-rich fuel is used to obtain hydrogen and a second liquid hydrocarbon fuel.

Abstract: A system for fracturing multiple wellbores on a multi-well pad can include a missile that receives high-pressure fracturing fluid from a plurality of pump truck. The system can also include a main manifold that receives the high-pressure fracturing fluid from the missile, where the main manifold includes multiple valves and multiple output channels, where each of the valves are operated between an open position and a closed position. The system can further include multiple wellbores including a first wellbore, a second wellbore, and a third wellbore, where the wellbores are connected to the output channels of the main manifold. The valves of the main manifold can be operated to enable simultaneous flow of the high-pressure fracturing fluid to the first wellbore, the second wellbore, and the third wellbore so that the first wellbore, the second wellbore, and the third wellbore are fractured simultaneously.

Abstract: Provided in one embodiment is a continuous process for converting waste plastic comprising polyethylene and/or polypropylene into recycle for polyethylene polymerization. The process comprises selecting waste plastics containing polyethylene, polypropylene, or a mixture thereof, and passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a pyrolysis oil comprising a naphtha, diesel and heavy fractions, and char. The pyrolysis oil, or at least a fraction, is passed to a filtration/metal oxide treatment, with the treated product passed to a refinery FCC unit. A liquid petroleum gas C3 olefin/paraffin mixture fraction is recovered from the FCC unit, as well as a C4 olefin/paraffin mixture fraction. The liquid petroleum gas C3 olefin/paraffin mixture fraction is passed to a steam cracker for ethylene production.

Abstract: Disclosed are systems and methods for thermal management of subsea conduits such as jumpers that provide the ability to alternate between cooling and heat retention of production fluids within the conduit as needed depending on the phase of operation. Adjustable insulation elements are provided on the conduits so that convective heat transfer between surrounding seawater and the conduit can be allowed or reduced. A control system can activate an alarm indicating the need to adjust the insulation depending on the temperature and/or flow rate of fluids in the conduit. Conventional conduits can be retrofitted by adding adjustable insulation elements to enable thermal management.

Abstract: Magneto-quasistatic signals may be used to enable under-liquid communication between devices. A magneto-quasistatic signal transmitter of an under-liquid device may transmit a magneto-quasistatic signal conveying communication data through liquid. A magneto-quasistatic signal receiver of another under-liquid device may receive the magneto-quasistatic signal and extract the communication data from the magneto-quasistatic signal. The under-liquid device that received the magneto-quasistatic signal may use the communication data, store the communicate data, and/or relay the communication data (e.g., to another under-liquid device, to an above-liquid device) using another magneto-quasistatic signal.
