This app provides a graphical very useful tool for training of Technicians, Drillers, Toolpushers, Drilling Engineers, Students and others professionals of the oil & gas industry to simulate a leak-off test. About the Leak-off Test on drilling operations: A test to determine the strength or fracture pressure of the open formation, usually conducted immediately after drilling below a new casing shoe.For new features, report bugs, improvements and suggestions please contact us: email@example.comNotes: - For well control simulation, use another app "Well Control Simulator". - For kick tolerance analysis, use another app "Kick Tolerance"; - For methods to control, use another app "Well Control Methods"; - For drilling simulation, use another app "Drilling Simulator"; - For hydraulic calculations, use another app "Drilling Hydraulics"; These tools can complement (work with) this simulator by importing /exporting data files which can be used in this application; Features: 1) Panel with the following parameters: dp pressure, choke pressure, mud pump speed, strokes totalizer, flow rate, mud weight and volume; 2) Intuitive graphical interface: Instruments with pointers to the parameters: DP pressure, choke pressure and open/close hydraulic choke; 3. Graph Options: - Pressures DP / Choke and Volume Pumped versus Pumping Time; - Pressures Dp/ Choke and Pumping Time versus Volume Pumped;4) Panel with alarms: pump failure, bop failure and bop status; 5) Toolbar with buttons: Data File, Well Config, Restart, Ranges, Set Alarms, Graph Limits, Pause/Continue, Restart, Set BOP, Send by email, about; 6) Set drill string with drillpipe1, drillpipe2, heavy-weight, drillcollar1 and drillcollar2; 7) Select floating rig or land rig; 8) Select unit systems: Metric, SI, Oilfield and others (mix). Select units also per parameter; 9) set fluid parameters: mud weight, plastic viscosity, yield point and initial gel; 10) Select rheological models: Power or Bingham; 11) Set gradients: absorption and fracture; 12) Set jet nozzles or fixed TFA; 13) Set choke parameters and BOP test pressure;14) Vertical or Slant Well Type (KOP, TVD and Measured Depth); 15) Set surface circulation equipments (mud pump and lines); 16) Save configuration to data files; 17) Select circulation options: drillpipe -> riser and drillpipe -> choke, Close/Open (Hard shut-in) the well; 18) Reset alarms: pump failure: max pump speed, max pump pressure and max pump power; 19) Register the pressures at the kill speed ; 20) Show schematic of well with drillstring;21) Shut-in the well using hard method; 22) Circulation on slow rate (kill speed);23) Useful for filling of Standardized Kill Sheets for Well Control;24) Useful for Filling of Previous Recorded Sheets;25) Analysis of the Choke Line effects in Maximum Choke Pressure;26) Analysis of the Effect of porosity and permeability on absorption curve;27) Simulation of the Leak-Off Test operation and Graphical Analize of the Leak-Off Test28) Capacities and Volumes calculations; 29) Hydrostatic and critical pressures calculations; 30) Hydraulics calculations; 31) Printing and email attachments with retina display ;32) Selection of units also per parameter;33) Ability to import well data from other apps;34) Ability to use the iPad on landscape position on all views;35) Recalculate DP as necessary to surface automatically with bit on bottom when editing BHA or Well Depth;DISCLAIMER:These tools & materials are provided 'as is' without warranties of any kind, express or implied.Please verify the tools provided by this application by yourself before you use them.
