MPD Simulator
Read full descriptionHide full description
This app is designed for both iPhone and iPad. This application provides practical simulations of the Dynamic Well Control on the Managed Pressure Drilling (MPD) operations in the oil field services. With Managed Pressure Drilling (MPD), when kicks occur, they are typically smaller, contained more quickly, and, in some cases, they may be circulated out through MPD equipment without drilling or circulation interruption. This simulator is the new project based on the Drilling Simulators on our portfolio, but specifically for dynamic well control on onshore and offshore operations (deepwater). MPD System on this simulator: 1. RCD – Rotating Control Device 2. Annular Preventer (or Drill String Isolation Tool – DSIT) 3. Automatic Choke for CBHP (Constant Bottom Hole Pressure), CDP (Constant Drill Pipe), CBP (Constant BackPressure or Choke Pressure) 4. RPD – Rig Pump Diverter 5. BPP – Back Pressure Pump Additional features: 1. Driller Interface based on Pressure Gauge, Weight Indicator, Rotary Torque gauge and Geolograph. 2. Choke Interface based on Digital Panel. 3. Graph in full screen (with background color in black or white) for analysis. 4. Special screen layout optimised for all iPhone and iPad models. 5. (iPad version) Three codes (admin, instructor, student) to view the gas into the borehole, the pressure at bottom, at shoe and at bop and to enable / disable the Lag Time (by adjusting the choke to change the kill pressure and drill pipe pressure, etc). (Attention: The Initial codes: "0000") NOTE: This simulator works with Auto/Manual Control on MPD Choke ONLY. For well control based on conventional rig choke panel, please buy the "Drilling Simulator 3" also available on our portfolio on the App Store. Thanks. Other features also available: A graphical very useful tool for training of roughnecks, derrickmen, drillers, toolpusher, drilling engineers and students in the well control procedures. - Ability to drilling, kick detection, shut-in, stabilisation of pressures; - Interactive System: no pre-set methods; - Ability to apply control methods: Driller's method, wait and weight, dynamic volumetric and static volumetric (lubricate and bleed); - Hydraulics and Hydrostatics; - Behavior of the kick; - Applied with subsea stack or surface stack; - Set well with until 4 sections: riser, casing, liner, open hole ; - Set Drillstring with drillpipe1, drillpipe2, heavy weight, drillcollar1, drillcollar2 Kick Model in this simulator: The model assumes that the kick starts as a single bubble at the bottom of the hole and migrates upward as a single bubble from the bottom to the surface.

The Mobile Command Center for Modern Administrators Turn your messy and unorganized classroom observations into professional, standards-aligned evaluations instantly. EvalScribe™ is the dedicated mobile command center for school administrators who refuse to let paperwork dictate their schedule. Many principals report that the process of taking raw observation data and turning it into a submission-ready formal evaluation can take up to an hour per teacher. EvalScribe™ effectively manufactures the one resource you can never get enough of: TIME. By automating the most tedious parts of the process securely from your phone, tablet, or Mac, EvalScribe™ allows you to complete teacher evaluations before you even get back to your office. TRANSFORM RAW NOTES INSTANTLY The patent-pending application bridges the gap between meaningful classroom interaction and mandatory documentation. You provide the raw observation data—whether typed, spoken, or handwritten—and EvalScribe™ does the rest by connecting modern technology with one of the most comprehensive mobile databases of teacher evaluation frameworks available in code - including Danielson, Marzano, the major rubrics used in all fifty states, and more. • Automatic Mapping: EvalScribe™ analyzes your notes against state teacher evaluation frameworks to suggest met standards. • Professional Voice: Turn your fragmented, raw observations into formal statements perfectly aligned with the language of your specific framework. • Evidence & Scoring: Get suggested competency levels for each standard, supported by evidence pulled directly from your own notes. • Coaching Scripts: Struggling with the post-evaluation meeting? EvalScribe™ generates targeted coaching topics and conversation starters based on the observation data to ensure meaningful feedback. ENTERPRISE-GRADE SECURITY & PRIVACY-FIRST ARCHITECTURE We know district data is sacred. EvalScribe™ is built on Microsoft Azure to ensure your data is safe, secure, and completely transient. • No Private Data Storage: We process your notes transiently. Once you finalize the evaluation, the data is cleared. We do not hold or store your records. • Human in the Loop: EvalScribe™ drafts the heavy lifting, but you make the final call and edits. • No Public Training: Your school's private data is never used to train public AI models. Stop letting mandatory documentation steal your time. Focus on the teachers and students, and let EvalScribe™ handle the paperwork.

Verdict
The clearest difference is price: EvalScribe at Free against MPD Simulator's $49.99. MPD Simulator's advantage is in-app purchases (none vs 2). On update cadence, ads, device support and iOS requirement there is nothing between them.
