Volumetric Method

Features
Read full description

This app is designed for both iPhone and iPad. This application uses the basic calculations of the Volumetric Method to control oil wells after the occurrence of kick during drilling operations on landing rigs (Onshore). - Starting on version 1.1, this app is optimized for horizontal and directional wells. It imports data files from our apps: (Driling Hydraulics, Drilling Simulators, Kick Tolerance, Kick Game, MPD Simulator and Well Control Simulators) available for sale in our portfolio on the App Store. It is can be applied on the oilfield and also help in the understanding of the Volumetric Method of well control. This app was developed based on existing spreadsheets. There is no comparison with any other software. Our goal was to create a low-cost application with the help of experts to share with drilling engineers, technicians, drillers, students and teachers of drilling engineering. There is no intention to replace the professional softwares. You can contribute with suggestions for improvements, correcting the translation to english, reporting bugs and spreading it to your friends.

Digitize Reality: Transform your mobile device into a powerful 3D scanner. Simply point and record to create professional-grade 3D models. Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocated 3D reconstructions. Visualize the captured model in the app, upload and export, and view it in AR. New ArcGIS Workflow: PIX4Dcatch now streams ArcGIS data in realtime in AR to provide in-field operators full contextual information about the entire site including 3D reconstructions and attributes. Our capture feature generates complete and defensible georeferenced 3D reconstructions which can be communicated seamlessly back to ArcGIS. New Guide-To Feature: PIX4Dcatch has a guide-to feature directing users to specified geolocated assets for staking, boosting onsite efficiency and accuracy. Just select the point or reconstruction you would like to find and follow the arrows in AR. WORKFLOW 1 – Scan & Capture Walk around your site. The app automatically gathers data and provides live feedback using iOS LiDAR, ensuring you capture every detail. For enhanced accuracy, use an RTK device compatible with PIX4Dcatch, PIX4D Autotags with a fully automated workflow, or combine both. 2 – Process, Analyze & Share Process your data by uploading to PIX4Dcloud for online analysis and sharing, or export to PIX4Dmatic for desktop processing. Both platforms offer a 14-day free trial. Projects can also be exported to third-party photogrammetry software. Measure spaces, document results, and enjoy all the benefits of a detailed 2D/3D model of your surroundings. 3 – View in AR Experience an immersive augmented-reality view. Display 3D models and points directly in your phone camera in AR. ____________________ USE CASES • Digitize construction sites • Measure stockpiles and other objects • Document underground utilities • Digitize indoor and outdoor spaces with Autotags • Visualize and verify 3D models in AR in real time • Perform single-point measurements with RTK accuracy ____________________ COMPATIBILITY • Optimized for LiDAR-equipped devices (Pro series phones) • All ARKit-enabled devices • RTK devices: Emlid Reach RX and RX2, TopCon HiPer CR, Bad Elf Flex Mini, Bad Elf Flex, Trimble DA2, Leica Zeno FLX100 ____________________ TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
