Drillsoft HDX Plus (HDX+)

Drillsoft HDX+ is a multiphase transient well model expanding on the Drillsoft HDX features with additional features such as Kick Simulation, Rapid Transient Influx Management Envelope, Jet Nozzles, Torque and Drag to empower the user with all necessary tools to plan the hydraulics for any well.

The Kick Simulator and Rapid Transient Influx Management Envelope Tools are capable of simulating well control events in land and offshore wells using water, oil and synthetic based muds while incorporating solubility and compressibility coupled with the pressure and temperature changes to deliver accurate solutions. Additionally, HDX+ allows the user to simulate kick circulation using MPD equipment and use of the marine riser or choke for influx removal.

Drillsoft HDX+ also features a Torque and Drag module that calculates axial tension, stretch, twist, hook load and torque. The module supports conventional and unconventional drilling methods which allows the modeling of all field operations including (RIH, POOH, Drilling and Rotating Off Bottom) for drill string, casing string, completion, and coiled tubing manufactured from steel and non-steel material.

Additional to the HDX features, Drillsoft HDX+ Features also include:

Well Control
Rapid Transient Influx Management Envelope
Kill Sheet
Torque and Drag
Jet Nozzles
Data Import and replay from database file

Data Table provides the guide for setting up the IME. The Results table displays the results for the Kick Intensity, Shut in Drill Pipe Pressure (SIDP), Max SBP, Casing ECD and Casing Pressure.

HDX+ Influx Management Envelope

Pre-Influx Surface Pressure Graph, displays the initial IME before the influx has been placed in the well. This graph will be updated as the Adjusted Post Influx Surface Pressure Graph, which incorporates the transient properties of the calculations by automatically setting the influx and circulating the influx to the surface.

HDX+ Well Control Simulation

Drillsoft HDX+ kick simulator is capable of simulating influx circulation while incorporating pressure, temperature, solubility and compressibility effects. The simulator provides access to manual or auto circulation (holding BHP constant) to safely circulate gas kicks out of the well.

HDX+ Torque & Drag

Drillsoft Torque and Drag module calculates axial tension, stretch, twist, hook load, and torque. It supports conventional and unconventional drilling operations which allows the modeling of all field operations including (RIH, POOH, Drilling and Rotating Off Bottom) for drill string, casing string, completion, and coiled tubing manufactured from steel and non-steel materials.

HDX+ Well Control Calculations

Drillsoft HDX+ also includes a kill sheet to plan a stepdown for circulating the kick and killing the well using either the driller’s method or wait & weight method. The killsheet includes pressure illustrations and graphical display for standpipe pressure and choke pressure that can be plotted against either time (min) or strokes. This kill sheet is also capable of automatically calculating the well control data to rapidly deliver the necessary parameters for killing the well.

Post-Influx Surface Pressure

The Influx Management Envelope (IME) is a guide to assess the limitations for the MPD equipment in case an influx is encountered. DrillSoft HDX+ provides the tool necessary to rapidly produce transient IME to aid with the planning and execution of a well. The output above displays the transient IME which incorporates solubility and compressibility and the changes created by pressure and temperature.
