Drillsoft HDX is REAL TIME Software that concentrates on drilling hydraulics and modeling wellbore pressures and temperatures during all phases of the drilling operation in extended-reach, highly deviated, horizontal and high temperature and high pressure (HTHP) wells. The simulator uses state of the art algorithms and provides the user with a wide range of modeling options.

The simulator will include a well trajectory and planning model well directional profiles, whether computed or imported from other directional survey service providers. The well trajectories will be displayed in 3-D profile.

Drillsoft HDX calculates and evaluates down-hole temperatures during drilling, circulating and shut-in operations for land and deep-water wells. A finite difference mathematical model has been developed to predict well bore and formation transient temperature behavior during drilling, fluid circulation and shut-in operations. This includes wells with multiple temperature gradients and well bore deviations, based on the fluids physical characteristics. The PVT model accurately calculates ECD and ESD according to formation and wellbore temperature profiles.

Drillsoft HDX can be used to analyze and optimize the hydraulics program for complex wells where there is a tight tolerance between ECD and fracture pressure, or pore pressure and fracture pressure. It takes into account the down-hole effects on rheological properties and mud density. We are working on add effects of RPM, tool-joints and cuttings loading on pressure loss calculations to improve ECDs calculations.

Hydraulic Optimization

One of the basic features of drilling fluid is to remove the drilled cuttings from beneath the bit. The fluid pumped through the bit nozzles exist at high velocity and impacts the hole bottom. After impact, a crossflow develops that forces cuttings away from hole bottom and up the annulus. Penetration rate and overall drilling cost depend greatly on the cleaning action of the drilling fluid.

Bit hydraulic horsepower, impact force, and nozzle velocity are common criteria for optimizing jet-bit hydraulics.

The concept of Hydraulic Optimization is based on the best condition to clean the well is when the force provided by the jets is the maximum.
If you drill a shallow hole section, the maximum impact force is recommended. However, if you drill a deeper section, the maximum hydraulic horsepower is better than the maximum impact force.

  1. Hi Dear,
    Trust all doing very well from yours side.
    Well, I had using HDX DEMO for some hydraulic simulation and I would like suggest some additional change at software if could possible.
    At data well configuration ( Tubullar) , could be add more cells for put additional casing size?

    For other considerations all in the software are running very well at my point.

    All best,
