Abstract: A database system is operable to determine a query for execution. A disjunction of a plurality of conjunctive normal form (CNF) filtering predicates is determined based on filtering predicates of the query. An IO pipeline is generated based on the disjunction of the plurality of CNF filtering predicates that includes, based on applying at least one type of optimization, at least one shared IO element common to multiple ones of plurality of the CNF filtering predicates. The IO pipeline is executed in accordance with execution of the query to generate a filtered subset of a plurality of rows that each meet at least one of the plurality of CNF filtering predicates.

Abstract: A method includes performing a search of an inverted index structure indexing values of a column to generate an in-range indexed value set by identifying all indexed values of the inverted index structure falling within a range corresponding to a range-based filter. A set of characteristics of the in-range indexed value set are identified based on performing the search of an inverted index structure. When the set of characteristics compare favorably to the set of index-usage requirements, output is generated based on performing a plurality of searches to the inverted index structure based on the in-range indexed value set. When the set of characteristics compare unfavorably to the set of index-usage requirements, the output is generated without performing any searches to the inverted index structure.

Abstract: The disclosure presents a technique to generate a fracture model using a differential stress map and model inputs. The technique simulates the fracture model using fracture fronts, initiated at perforations of a perforation stage of a hydraulic fracturing (HF) wellbore. Each fracture front is evaluated using a propagation step of a fracture model process. Using the relative differential stress states, a fracture pattern is composited to the fracture model. At each propagation step, the total energy available from the simulated HF fluid being pumped into the wellbore location is reduced by the amount necessary to generate the computed fractures. Once the remaining energy is reduced to a level where no further fractures can be created, or if a map boundary is encountered, the fracture model process terminates. The generated fracture model can be communicated to update HF job plans, wellbore placements, and other uses of the fracture model.

Abstract: A drill bit subsystem can include a drill bit, a processor, and a non-transitory computer-readable medium for storing instructions and for being positioned downhole with the drill bit. The instructions of the non-transitory computer-readable medium can include a machine-teachable module and a control module that are executable by the processor. The machine-teachable module can receive depth data and rate of drill bit penetration from one or more sensors in a drilling operation, and determine an estimated lithology of a formation at which the drill bit subsystem is located. The control module can use the estimated lithology to determine an updated location of the drill bit subsystem, and control a direction of the drill bit using the updated location and a drill plan.

Abstract: Methods and systems for managing and distributing centrally-received leads to a plurality of remote dealers are disclosed. The management and distribution of leads may be handled by the centralized methods and systems regardless of the type of lead management software each supported dealer may employ. Also disclosed are systems and methods for collecting and processing information relating to the effectiveness of a dealer's follow-through on leads that it receives, independent of how that dealer processes leads or what type of lead management software the dealer uses. Additional disclosures include systems and methods for transmitting leads and lead follow-up and effectiveness information between a central system that receives leads from a plurality of sources and a dealer via an intermediary.

Abstract: A method of developing a sales lead includes receiving a sales lead from a sales lead source and supplementing it with additional information. The supplemental information may be useful in determining the attractiveness of the sales lead. Attractiveness information may be quantified or otherwise expressed, added to the sales lead, and provided to a sales lead recipient. The sales lead recipient may then quickly and efficiently assess the value of the sales lead.
