  • Publication number: 20150211339
    Abstract: The feasibility of performing hydraulic fracturing can be assessed by analyzing the effect of skin on the overall deliverability of a reservoir. Aspects of the disclosure provide a method to determine equivalent skin in hydraulic fractured system through a semi analytical correlation obtained by numerical modeling. Two 3D models are considered: a base case without fracture and a complex case with fractures. The base case is simulated by varying matrix permeabilities while the fractured model is run with different sets of varying fracture's lengths, widths, and permeability as well as matrix permeabilities. The two cases are comparatively analyzed and skin is determined. A generalized correlation for determination of skin is derived through application of multivariate regression technique on obtained skins and their corresponding variables.

  • Patent number: 8599985
    Abstract: In accordance with an embodiment of the present disclosure a phase-locked loop comprises a voltage controlled oscillator (VCO) configured to generate an output signal based on an input reference signal. The phase-locked loop further comprises a first charge pump communicatively coupled to a control input of the VCO and configured to generate, for a duration of time following occurrence of an event, a first control signal. The first control signal is independent of the output signal and is for causing the output signal to have a first frequency based on a second frequency of the input reference signal. The phase-locked loop further comprises a second charge pump communicatively coupled to the control input of the VCO. The second charge pump is configured to generate, after the duration of time, a second control signal.

  • Publication number: 20130212317
    Abstract: Storage and host devices are provided for overlapping storage areas for a hibernation file and cached data. In one embodiment, a storage device is provided that receives a command from a host device to evict cached data in a first address range of the memory. The storage device then receives a command from the host device to store a hibernation file in a second address range of the memory, wherein the second address range does not exist in the memory. The storage device maps the second address range to the first address range and stores the hibernation file in the first address range. In another embodiment, a host device is provided that sends a command to a first storage device to evict cached data in a first address range of the first storage device's memory. The host device then sends a command to the first storage device to store a hibernation file in the first address range.

  • Patent number: 8442095
    Abstract: Methods and apparatus for code phase processing in a wireless communication device are described herein. A wireless device performs code phase search on a pseudo random code spread signal received over a wireless channel. A correlator correlates the received signal to a plurality of code phases in each of a plurality of frequency hypothesis. A maximum peak and a second peak are determined from the correlation results. Cross correlation processing is performed on the maximum peak and the maximum peak is discarded in favor of the second peak for position processing based on the results of the cross correlation.
