Gradient Planner

Cloud-based MPD hydraulics planning with controller response prediction.
Build engineering plans grounded in physics, refined by operational data.

What It Does

Feasibility Studies

Evaluate MPD concepts against formation pressure profiles. Determine optimal mud weights, surface backpressures, and equipment requirements. Generate technical feasibility documentation for operator and regulatory review.

Detailed Engineering Plans

Displacement schedules for mud rollovers, surge and swab analysis for safe tripping, managed pressure cementing procedures, and connection flow-to-pressure tables. Complete pre-job packages ready for field execution.

Controller Response Prediction

Pre-job prediction of automated choke controller behavior under planned operating conditions. Understand how the control system will respond before equipment reaches the rig site. This capability is unique to Gradient.

Regulatory Documentation

Operational matrices, influx management envelopes (IME), kick and loss scenarios, tolerance calculations, and response procedures. Generated directly from your well plan data.

Hydraulics Engine

Steady-state hydraulics built on API RP 13D with extensions for MPD-specific calculations.

Rheology Models

Bingham Plastic, Power Law, Herschel-Bulkley, and Robertson-Stiff. Select the model that best fits your fluid system.

Multi-Fluid Displacement

Track multiple fluids simultaneously through the wellbore during displacement, cementing, and pill placement operations.

Thermal Modeling

Temperature-dependent rheology corrections based on wellbore thermal profiles. Critical for deep wells and HPHT applications.

Surge and Swab

Trip speed optimization to maintain annular pressures within the drilling window during pipe movement.

Platform

Cloud + Offline

Runs in any modern browser. Works offline for rig-site use with no internet connectivity. Syncs when connection is available.

Metric + Imperial

Full unit system support. Switch between metric and imperial at any time without re-entering data.

Report Generation

Automated engineering reports and regulatory documentation generated directly from your well plan.

Adaptive Models

Import actual well data to refine friction correlations and rheology corrections. Each project improves the baseline for the next.
