Abstract: Methods include introducing a multistage treatment fluid into one or more intervals of a wellbore, wherein the treatment fluid contains one or more stages of a polymer-forming composition and one or more stages of a spacer fluid and initiating polymerization of the one or more stages of polymer-forming composition. Methods may include designing a multistage treatment fluid containing one or more stages of a polymer-forming composition and one or more stages of a spacer fluid, wherein or more stages of the polymer-forming composition comprises a thermosetting polymer; and pumping the multistage treatment fluid into a wellbore, wherein the pumping rate is determined by constructing a model based upon (a) the minimum pumping rate determined from the critical reaction temperature and the downhole temperature, (b) the fracture closing time, (c) the temperature within one or more fractures, and (d) the maximum pumping rate.

Abstract: A data aggregator includes a memory, a network interface, a vectorization engine, and an aggregator. The memory stores a plurality of aggregation rules. The network interface retrieves a plurality of transactions that includes a first transaction and a second transaction. The vectorization engine determines a first transaction vector for the first transaction and a second transaction vector for the second transaction. The aggregator determines that the first transaction occurred during a first life event and that the second transaction occurred during a second life event. The aggregator also determines that the first life event and the second life event are the same and in response to that determination, assigns the first transaction and the second transaction to a cluster for the first life event. The aggregator further stores the first life event, the second life event, and an identifier for the cluster to the database.

Abstract: Methods and systems relate to a pressure exchanger which exchanges pressure energy from a high pressure clean fluid system to a relatively low pressure harsh fluid system for use in pressurizing the harsh fluid and directing the fluid to a wellbore as high pressure harsh fluid without the harsh fluid contacting identified portions of the pressure exchanger.

Abstract: A technique for reducing harmonic vibration in a multiplex multi-pump system. The technique includes establishing a lower bound of system specific vibration-related information such as via pressure variation or other vibration indicator. Establishing the lower bound may be achieved through simulation with the system or through an initial sampling period of pump operation. During this time, random perturbations through a subset of the pumps may be utilized to disrupt timing or phase of the subset. Thus, system vibration may randomly increase or decrease upon each perturbation. Regardless, with a sufficient number of sampled perturbations, the lower bound may be established. Therefore, actual controlled system operations may proceed, again employing random perturbations until operation of the system close to the known lower bound is substantially attained.

Abstract: A method for monitoring performance of an electric submersible pump. The method includes receiving data indicating a plurality of observable parameters from one or more sensors, generating a reduced set of components representative of at least some of the observable parameters and the reduced set having a dimensionality less than the plurality of observable parameters, identifying one or more components of the reduced set that captures a total variance of the plurality of observable parameters above a predetermined threshold, constructing at least one manifold of normal operation of the electric submersible pump in a reduced component space, receiving additional data from the sensors, transforming the additional data into the identified components establishing an electric submersible pump performance, and detecting whether a deviation of the electric submersible pump performance from a normal mode of operation of the electric submersible pump exceeds a predetermined threshold.

Abstract: A method for predicting equipment failure includes receiving parameter sample values associated with parameters of benchmark equipment and operational status information associated with the benchmark equipment. The parameter sample values and operational status information are periodically acquired. A model is generated for relating one or more of the parameters to benchmark equipment failure. For each parameter, a threshold value at which an output of the model indicates benchmark equipment failure is determined. Next, parameters of an equipment under test having parameter sample values that match the determined threshold values are determined. For each determined parameter, benchmark equipment having parameter sample values that match the parameter sample values of the equipment under test that match the determine threshold values are determined. Survivability data for the equipment under test is generated based on survivability data associated with the determined benchmark equipment.

Abstract: Embodiments of the invention relate to systems, methods, and computer program products for a high performance data copy utility that is operable to dynamically copy data from a source database to a target database in an object-relational database environment. High performance is realized by defining, prior to copying the data, performance boundaries of the source and target environment, such as the quantity of data (i.e., commit points) and quantity of parallel processes (i.e., parallel threads) applicable to a copy job. Moreover, the copying schema of the present invention allows for data to be copied from one database to another database without the need higher level privileges, such as database administrator (DBA) or data definition language (DDL), which would otherwise require changing the structure of the database. In this regard, embodiments of the present invention rely solely on lower-level data manipulation language (DML) privileges configured for inserting, updating and deleting data structures.

Abstract: A zero-emissions power plant receives natural gas from wells at elevated pressure and temperature. Gas is expanded through one or more turbo-expanders, preferably reformed, and sent to a fuel cell where electricity, heat, carbon-dioxide, and water are generated. The carbon-dioxide is compressed by at least one compressor and piped downhole for sequestration. The turbo-expanders have shafts which preferably share the shafts of the compressors. Thus, energy given up by the natural gas in the turbo-expanders is used to run compressors which compress carbon dioxide for downhole sequestration. In one embodiment, the natural gas is applied to heat exchangers in order to generate a stream of liquid natural gas. The remainder of the gas is expanded through the turbo-expanders and processed in the reformer prior to being sent to the fuel cell. A shifter may be used between the reformer and fuel cell. A solid oxide fuel cell is preferred.
