  • Publication number: 20250146394
    Abstract: Disclosed herein are methods for treating hydrocarbon-bearing formations previously subjected to hydraulic fracturing. In at least certain embodiments, a purpose of the treatment is to mobilize incremental oil from the formation by increasing effective Stimulated Rock Volume (eSRV) using diverters and a treatment composition that includes LPG as carrier fluid. At least some of the methods include pumping into the wellbore a treatment composition comprising LPG combined with one or more surfactants each of which is fully or partially dissolved into the LPG, causing the treatment composition to make contact with water residing in the formation such that at least a portion of the one or more surfactants dissolves into the water, and recovering a composition that includes residual hydrocarbons and at least some of the LPG and water that resided in the formation and at least some of the one or more surfactants that were pumped into the wellbore.

  • Patent number: 9152691
    Abstract: Techniques are provided for improving the speed and accuracy of analytics on big data using theta sketches, by converting fixed-size sketches to theta sketches, and by performing set operations on sketches. In a technique for performing a set operation, two sketches are analyzed to identify the maximum value of each sketch. The maximum values of the two sketches are compared. Based the comparison, one or more values are removed from the sketch whose maximum value is greater. After the removal, a set operation (e.g., union, intersection, or difference) is performed based on the modified sketch and the unmodified sketch. A result of the set operation is a third sketch, which may be used to estimate a cardinality of the larger data sets that are represented by the two input sketches.

  • Publication number: 20120005029
    Abstract: A method for handling priorities in an ad exchange auction includes: constructing an exchange graph including nodes representing publishers and advertisers and directed edges that represent bilateral business agreements connecting the nodes; receiving an opportunity for displaying an ad to a user from a publisher; receiving ads from which to choose to fill the opportunity, the ads including respective advertiser priorities (A) and bid amounts; receiving a publisher priority (P) the ads as assigned by the publisher; constructing a priority triple (P,A,M) for each of at least some of the plurality of ads, the triple including the publisher priority (P), the advertiser priority (A), and a money payable to the publisher (M); comparing the P, the A, and the M of respective priority triples for the ads according to at least one scoping rule and at least one precedence rule, to determine the ad with which to fill the opportunity; and delivering the ad determined to have the highest priority to a web page of the publ

  • Publication number: 20110264516
    Abstract: A method is disclosed for limiting latency in filling a display opportunity in an ad exchange including: constructing an exchange graph comprising nodes representing a plurality of publishers and advertisers, the exchange graph also including a plurality of directed edges that represent bilateral business agreements connecting the nodes; receiving an opportunity for displaying an ad to a user, wherein the opportunity is associated with a publisher node; receiving ads from the advertisers from which to choose to fill the opportunity; determining whether a threshold total number of ads (T) is surpassed by the received ads; and randomly downsampling the number of ads from each of at least some of the advertisers when the threshold total number of ads (T) is surpassed by the received ads to reduce the total number of ads to a target number of ads (S) that reduces overall latency in determining which of sampled ads will fill the opportunity.

  • Publication number: 20090254523
    Abstract: Methods and apparatuses relate to hosting an inverted index for term-based document searching. According to disclosed aspects, each bank of a plurality of banks receives a plurality of Document IDentifiers (DocIDs) in the inverted index, and within each bank, posting lists for each term are determined large or small. DocIDs for large posting lists are distributed among computers in a bank while responsibility for producing DocIDs identifiers in a small posting list are distributed by term to one or fewer computers in the bank. During operation, each term of a query is distributed to each bank, and then for small terms, only those computers assigned responsibility for a given term need to search for responsive DocIDs. DocIDs can be redistributed among computers in a bank such that results are presented from the computers that would have produced those results in a cluster having a pure DocIDs distribution scheme.

  • Publication number: 20090210344
    Abstract: System and method for providing an address verification response associated with a financial presentation device being used to conduct a transaction with a merchant. The system includes a memory storing addresses of holders of financial presentation devices and a date corresponding to a last change of address associated with each financial presentation device, and an address verification program which is operable to receive a request from the merchant to verify an address associated with the financial presentation device; determine a temporal indicator identifying a time period since a holder of the financial presentation device last changed the address; and provide the determined temporal indicator with the address verification response to the merchant.
