20160032666 | Hydraulic Draw Works - A hydraulic draw-works comprises several hydraulic cylinders of mixed orientation, such that some hydraulic cylinders actuate upwards and some hydraulic cylinders actuate downwards. These cylinders are connected by a plurality of braces mounted along a guide rail, and the drill head is mounted on a carriage along the guide rail and actuated by the upwards-oriented cylinders. The use of mixed orientation cylinders allows the effective vertical stroke length required to raise and lower the drill head to be halved. In a preferred embodiment, through-rod porting of the downwards-oriented cylinders supplies hydraulic fluid to the remainder through a manifold, and digitally controlled directional valves allow precise control of the drill head. | 02-04-2016 |

20100061184 | Common Reflection Azimuth Migration - Method for migration of seismic data into datasets having common azimuth angle at the reflection point. A velocity model is selected that prescribes subsurface P and/or S wave velocities including any required anisotropy parameters. ( | 03-11-2010 |
20110199860 | Method For Imaging of Targeted Reflectors - Techniques are disclosed for performing time-lapse seismic monitor surveys with sparsely sampled monitor data sets. A more accurate 3D representation (e.g., image) of a target area (e.g., a hydrocarbon bearing subsurface reservoir) is constructed using the sparsely sampled monitor data set ( | 08-18-2011 |

20130064431 | Efficient Computation of Wave Equation Migration Angle Gathers - Method for efficient computation of wave equation migration angle gathers by using multiple imaging conditions. Common reflection angle or common azimuth gathers or gathers including both common reflection angles and common azimuth angles are produced as the data are migrated. In the course of either wave equation migration or reverse time migration, the pressures and particle motion velocities that need to be computed are sufficient to also compute the Poynting vector pointing in the direction of source-side ( | 03-14-2013 |
