Publication number: 20200186678Abstract: A first number of color patches are printed with a target printing system to obtain a sparse color gamut characterization. A second number of color patches are printed with a reference printing system to obtain a reference color gamut characterization. The second number is greater than the first number. A dense color gamut characterization is generated with a transformation of the reference color gamut characterization to the sparse color gamut characterization. A color management resource can be generated for the target printing system from the dense color gamut characterization.Type: ApplicationFiled: June 15, 2017Publication date: June 11, 2020Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Miguel Angel Lopez, David Berfanger, Morgan T.

Publication number: 20200174446Abstract: Methods of managing aggregate inventory. The methods include utilizing a dynamic protocol for an oilfield operation with aggregate from chambers of a multi-silo system wherein each chamber accommodates a single aggregate type throughout operations. However, the chambers also have a dynamic classification as either active, idle or reserved depending on the stage of operations. Once more, even though each silo may accommodate multiple chambers, unique techniques may be utilized to obtain real-time inventory information for each chamber via weight measurement of entire silos.Type: ApplicationFiled: February 3, 2020Publication date: June 4, 2020Inventors: Miguel Angel Lopez, Marcos Suguru Kajita, Bansi Chauhan, Christopher Todd Shen

Patent number: 10415562Abstract: Automated operation of well site pumping equipment, including generating a mathematical belief model for maintaining an interrelationship between flow rate achievable by a pump unit discharge pressure of the pump unit, and probability of achieving the flow rate at corresponding discharge pressure. Speed of the pump unit is controlled to achieve a target speed based on a flow rate set-point and the mathematical belief model and updating the mathematical belief model at least while the target speed is achieved. Updating the mathematical belief model may include increasing the probability of achieving the flow rate set-point when actual flow rate of the pump unit is not less than the flow rate set-point and decreasing the probability of achieving the flow rate set-point when the actual flow rate of the pump unit is less than the flow rate set-point.Type: GrantFiled: December 19, 2016Date of Patent: September 17, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Marcos Kajita, Miguel Angel Lopez, Hassanain A.

Publication number: 20180048544Abstract: A supervisory control and data acquisition (SCADA) unit and technique for managing communications over a network of defined capacity. The unit and techniques include safeguarding the network while allowing for operations to proceed at an oilfield. The safeguards allow for multiple additional and different types of equipment to be added to or removed from the network while being managed by a single SCADA unit. This may be achieved through unique filtering protocols which prevent unidentified and/or unconfirmed equipment and devices from being added to the network merely due to be detected at the oilfield.Type: ApplicationFiled: March 8, 2016Publication date: February 15, 2018Inventors: Marcos Suguru KAJITA, Clinton D.
