The Well Design module

One workspace, one data model, from spud to end of well

Well planning, positional integrity, drilling engineering and execution reporting in a single module. Every page shares the same project selection, set once and carried through planning, engineering, execution and reporting.

Built for: Drilling contractors, directional companies and operator drilling teams
Validated against: Professional directional plans and measured field data
Every result carries: The engine version and the warnings it was produced with

Foundation

The project, and what it is built on

Each job is a project containing its wells and wellbores. Job identifiers, parties, location and dates are stored once and read by every report cover at generation time.

Surface locations are stored with their coordinate reference system, north reference and grid convergence. The pad layout is drawn to scale from the slot coordinates, and the site's geomagnetic reference model is computed in the application from the published IGRF model.

The Well Design project workspace showing job data, parties, location and dates — One project selection, carried through every page of the module.

Foundation

What the well is made of

The wellbores and surveys page with plan trajectory and definitive survey — Wellbores and surveys. Each wellbore stores its planned trajectory and its definitive measured survey. Surveys import from files or from the platform's historical well data, and carry per-station quality-control status.

Hole sections and casing strings with a live well schematic — Hole and casing. Sections and strings are defined per wellbore with a live schematic. The same geometry drives friction assignments and annular calculations, and distinguishes casing that has been run from casing that is planned.

The trajectory planner with a sequence of sections and the resulting plan and section views — Trajectory planner. Trajectories are designed as a sequence of sections and solved on the computation engine. Solved designs are stored with their engine version and any warnings, and the section and plan views update on every solve.

Positional integrity

Anti-collision scanning and analysis

Separation-factor scanning follows the ISCWSA pedal-curve method against all selected offsets, including planned wells. Results are stored per station with the scan policy, the geomagnetic header and the trajectory source of every well, forming an auditable record of each scan.

The analysis is presented three ways: a ladder plot of separation distance against measured depth for every offset, a travelling cylinder showing offset bearings and distances around the reference wellbore, and a spider plot of the pad at any chosen true vertical depth.

Anti-collision scanning results with separation factors listed per station — Scans stored per station, with policy, geomagnetic header and trajectory source.

Positional integrity

Survey quality control, and the wells around you

Each survey leg is checked for build rate, turn rate and dogleg consistency, with field-acceptance checks against the site's geomagnetic reference where sensor data is present. Verdicts can be written back to the survey stations, and the survey programme prints on certified reports.

Offset wells are attached from the platform's historical daily-report database, including their surveys, or entered from imported survey files. The project's offset selection is saved and used by anti-collision scanning.

All wellbores of a pad shown together in a three-dimensional interactive scene — Plans, surveys and sidetracks placed by wellhead geodesy in one scene, with closest-approach measurement and optional survey-uncertainty ellipsoids.

Engineering

The string, and what it will do

Bottom-hole assemblies are defined component by component with dimensions, weights and connections, supported by a component catalogue and import from historical runs. The same drillstring definition is used by every engineering module.

Torque and drag. Hookload roadmaps computed across a depth range in one operation — pick-up, slack-off and rotating weights at each bit depth, with casing shoe position and friction factors per hole section. Friction sweeps and buckling screening are included.
Hydraulics. The circulating system end to end: standpipe pressure broken down by component, ECD at the bit and shoe including cuttings loading, annular velocities, and an operating envelope covering hole-cleaning minimums, laminar limits, system volumes and lag times.
Critical speed. Lateral vibration screening across the operating RPM range, which identifies the resonance bands before they are drilled through.

The BHA builder, with components listed and the assembly drawn alongside — The BHA builder: components with dimensions, weights and connections, drawn as the assembly is defined.

Execution

What the well actually did

Daily reports carry coded activity breakdowns, depths, mud properties and non-productive time recorded to the minute. Activity and phase codes come from configurable vocabularies, and the time distribution feeds invoicing.

Slide sheets record ordered drilling intervals with eight operation modes, toolface, and operating parameters per interval, tied to the BHA and the wall clock. Recorded motor yields are plotted against survey-derived curvature for reconciliation. Pipe tally is joint by joint with running totals and in-hole status.

Plan versus actual comparison showing three-dimensional distance and vertical and lateral offsets — Plan versus actual — the definitive survey compared with the planned trajectory in the plan's own reference frame, with three-dimensional distance, vertical and lateral offsets, and measured-depth lead or lag at every station.

Deliverables

The documents at the end of it

Report definitions cover plan listings, survey listings, certified reports with sign-off, anti-collision reports, error-ellipse listings and BHA sheets. The End-of-Well composite assembles the wellbore's complete record into one document, and the Wall Plot produces a landscape deliverable of the definitive and planned trajectories with casing shoes, formation tops and anti-collision results.

From the last survey station the engine projects the path ahead, solves the build rate required to land at a target depth and inclination, and solves two-curve profiles to a specified landing point — stating its assumptions and the engine version that produced them. Motor performance reports are prefilled from the BHA run, slide sheet and daily records, then completed for the client file.

Tool orders, shipping tickets and rate-sheet invoicing are managed alongside the engineering record, with inventory movements and line derivations handled by the platform.

An end-of-well composite report and a wall plot produced by the module — The end-of-well composite and the wall plot, generated from the same record.

Validation

Checked against real plans and real wells

The module's trajectory, anti-collision, torque-and-drag and hydraulics computations have been validated against professional directional plans and measured field data. Every stored result carries the engine version and the warnings it was produced with.
