    Abstract: Methods and apparatus relate to in situ combustion. Configurations of the injection and production wells facilitate the in situ combustion. Utilizing wet combustion for some embodiments promotes heat displacement for hydrocarbon recovery with procedures in which one or more of the production and injection wells are configured with lengths deviated from vertical. In some embodiments for either dry or wet combustion, at least the production wells define intake lengths deviated from vertical and that are disposed at staged levels within a formation. Each of the productions wells during the in situ combustion allow for recovery of hydrocarbons through gravity drainage. Vertical separation between the intake lengths of the production wells enables differentiated and efficient removal of combustion gasses and the hydrocarbons.

    Abstract: The invention relates to seismic surveying where complex geologies are likely to create data that is confusing or ambiguous for a conventional matrix of acquisition source points and receiver locations. With some understanding of the geological substructure, the acquisition source points and receiver locations that optimize the imaging may be found by using a reciprocal two-way wave equation propagation method coupled with the best geologic model available. With this, the acquisition source points and receiver locations that optimize the imaging may be used in seismic survey to better resolve the substructure and avoid the inclusion of data that obscures understanding of the substructure.

    Abstract: The invention relates to a seismic acquisition process where multiple seismic sources are used to acquire seismic energy using encoding so that all of the sources may deliver seismic energy at the same time where the sweeps are arranged to be back to back with no listen time and wherein a pseudo listen time that is uncontaminated is created in the composite data record. After the listen time is created, the composite data may be source separated for further processing and analysis.

    Abstract: The invention relates to a method for history matching a facies geostatistical model using the ensemble Kalman filter (EnKF) technique. The EnKF is not normally appropriate for discontinuous facies models such as multiple point simulation (MPS). In the method of the invention, an ensemble of realizations are generated and then uniform vectors on which those realizations are based are transformed to Gaussian vectors before applying the EnKF to the Gaussian vectors directly. The updated Gaussian vectors are then transformed back to uniform vectors which are used to update the realizations. The uniform vectors may be vectors on which the realizations are based directly; alternatively each realization may be based on a plurality of uniform vectors linearly combined with combination coefficients. In this case each realization is associated with a uniform vector made up from the combination coefficients, and the combination coefficient vector is then transformed to Gaussian and updated using EnKF.

    Abstract translation: 本发明涉及一种使用综合卡尔曼滤波（EnKF）技术对相位地统计模型进行历史匹配的方法。 EnKF通常不适用于不连续相模型，如多点模拟（MPS）。 在本发明的方法中，生成实现集合，然后将这些实现所基于的均匀向量在将EnKF直接应用于高斯向量之前被变换为高斯向量。 然后将更新的高斯向量转换回用于更新实现的均匀向量。 均匀向量可以是实现基础的向量直接; 或者每个实现可以基于与组合系数线性组合的多个均匀向量。 在这种情况下，每个实现与由组合系数组成的均匀向量相关联，然后将组合系数向量转换为高斯并使用EnKF更新。

    Abstract: The invention relates to a conical piled monopod which is a fixed, ice worthy structure used in cold weather offshore environments for accessing hydrocarbon deposits under the seafloor. The conical piled monopod provides a much lower cost offshore facility as compared to a very large, gravity based structure. The conical piled monopod has a base that is designed to rest on a minimally prepared seafloor and be held in a fixed locations by pilings inserted deep into the seafloor. The top deck is designed to be at least 60 feet across with a sloped or inclined perimeter surface to bend and break the ice that comes into contact with the conical piled monopod as the ice would otherwise impose significant lateral forces.
