Paradigm Sysdrill Hydraulics optimization and analysis system is used to model downhole circulating pressures during drilling, tripping, and running casing. There are several modes of optimization to enhance bit hydraulic performance and ensure effective hole cleaning.
A rheology model selector can analyze all types of drilling fluids and automatically select the most suitable mud rheology model based upon actual Fan viscometer readings.
Users can analyze Swab/Surge and equivalent circulating density (ECD) in order to reduce the risk of formation breakdown. The maximum running speeds for bottom hole assemblies (BHAs) and casing strings can be calculated to improve efficiency and reduce rig costs. Individual tool joints are considered in the ECD calculation for modeling narrow mud window.
A sensitivity analysis allows calculation of pressures and ECDs at varying flow rates and indicates minimum and maximum recommended flow rates.
You can use the Volume Calculator to determine mud volumes for a number of circulating scenarios, including pill spotting, cement plug, wash out calculation, and reverse circulating.
For deep water operations a riser booster and dual gradient systems are supported.
Paradigm Sysdrill BHA String Constructor™
With the Paradigm Sysdrill BHA String Constructor you can quickly construct complex BHAs by rapidly filtering extensive catalogs of drilling equipment, including bits, collars, pressure loss devices, centralizers, stabilizers, torque reduction subs, and accessories. You can store BHAs that are created in catalogs for future use, and new catalogs can be added. A customizable graphical view combines mechanical properties and physical dimensions.
Paradigm Sysdrill Temperature Modeling
Paradigm Sysdrill Temperature Modeling provides a quasi-steady state temperature model, with an advanced compositional density and HTHP rheology model to simulate a number of drilling scenarios, including; complex geothermal gradients, horizontal wells, riser booster, and dual gradient systems. This enables more accurate prediction of ECD and ESD (equivalent static density) downhole mud density and rheology under HPHT conditions.
Paradigm Sysdrill Well Control
The well kick tolerance calculator in Paradigm Sysdrill Well Control is used to ensure that casing shoes are set at safe depths and to avoid formation fractures using “Single Bubble Method.” Users can quickly produce a Kill Sheet including dynamic MAASP volumes, strokes, and a pressure step down chart required to control the well.
Paradigm Sysdrill Cementing
Paradigm Sysdrill Cementing optimization and analysis system is used for lanning cementing operations to help ensure the secure and safe installation of casing strings. It helps you optimize pumping operations for variable flow rate pump schedules, fixed flow rate, fixed bottom hole pressure, and free fall to manage downhole pressures. During calculations, an animated wellbore schematic displays fluid flow regimes, bottom hole pressures, ECDs, and flow rate as cements are circulated. Bottom hole pressures are plotted against formation breakdown pressure to prevent open hole fractures.
