Borewell Air Duty Enquiry

01 — Direct engineering answer

A borewell air-duty enquiry is a controlled intake for identifying the drilling task, compressor/booster duty, pneumatic tool interface, operating conditions, logistics and evidence gaps before a technical team recommends a supply configuration. The customer submits a structured brief; the system acknowledges receipt only after confirmed persistence; a named technical role checks completeness, resolves unknowns and records the handover. Submission is not proof of equipment suitability, stock, drilling performance or deployment availability.

03 — Audience and intent

Serve drilling contractors, rig owners, water-well project teams, procurement coordinators and site engineers. Distinguish a new equipment enquiry, temporary rental requirement, booster/pressure clarification, existing compressor suitability review, loss-of-performance problem and project planning request. The initial choice controls follow-up fields and review queue.

04 — Customer decision path

Let users choose a task type, describe the borewell job, enter available duty information, add safe supporting files, review privacy terms, submit, receive a verifiable reference and learn which information the technical reviewer may still request. Offer a non-form contact route if accessibility or uploads fail.

05 — handover contract

The reviewer should receive a compact engineering brief, attachment manifest, uncertainty flags and customer contact permissions—not a pasted article.

06 — Request classification

Branches: (A) compressor selection, (B) existing system assessment, (C) temporary air rental, (D) booster/pressure-stage question, (E) troubleshooting of air delivery or hole cleaning, (F) request for site technical discussion. A branch may include more than one concern; keep the primary engineering decision explicit.

07 — Borehole geometry

Capture proposed/actual borehole diameter with unit, current and target depth, casing status, drilling stage and any known restrictions. Depth alone cannot determine compressor pressure or delivered flow. Ask whether values are planned, measured or estimated and preserve the uncertainty tag.

08 — Drilling method and formation

Ask whether the work uses DTH hammer, rotary air drilling, air-assisted drilling or another method. Capture formation description and known changes with depth, if available. Do not treat customer descriptions of hard rock, fractured ground or wet zones as independently verified geological data.

09 — Hammer and bit identity

Request hammer manufacturer/model, nominal size, bit diameter, operating pressure range and manufacturer air-consumption data if available. Allow unknown. Do not infer a universal hammer requirement from bit size alone; performance depends on the exact tool, pressure at hammer and operating conditions.

10 — Working pressure boundary

Ask where the stated pressure applies: compressor discharge, booster outlet, rig manifold or hammer inlet. Capture bar(g), psi(g) or other declared basis; label gauge versus absolute. Do not accept an unlabelled number as a verified hammer inlet pressure. The technical reviewer must reconcile pressure losses through treatment, hose, valves and fittings.

11 — Airflow boundary and reference conditions

Request flow in m³/min, cfm or another defined unit; record whether it is free-air delivery, manufacturer-rated flow, measured flow or estimated demand. Ask for reference pressure/temperature where supplied. Rated displacement, nominal package capacity and delivered flow at the tool are not interchangeable.

12 — Hole cleaning and cuttings transport

Ask about inadequate flushing, cuttings return, repeated jamming, excessive dust or wet cuttings. Hole cleaning depends on annular geometry, effective air delivery, cuttings load and drilling conditions; a web form must not auto-approve a compressor based on a single nominal annular-velocity calculation. Route technical calculation to the Borewell Hub.

13 — Compressor and booster inventory

Capture existing compressor type, make/model, pressure rating, rated capacity, hours, operating configuration and booster identity where relevant. Identify parallel machines, standby arrangements and whether capacities refer to the same reference conditions. Request nameplate photographs only where safe and authorised.

14 — Hose and manifold interface

Collect hose internal diameter, approximate length, number of sections, couplings, bends, valves, filters and any suspected restrictions. Ask for rig inlet size and existing connection drawing. Record customer estimates separately from measured dimensions. Final pressure-drop evaluation requires actual operating flow, geometry and fittings.

15 — Site altitude and ambient conditions

Capture project locality at district/city level, approximate elevation if known, typical ambient temperature, dust, rain and operating exposure. Elevated sites and hot conditions may affect compressor/engine performance; require OEM-specific derating review rather than generic percentage assumptions.

16 — Water ingress and drilling interruptions

Ask whether water enters the hole, whether air is mixed with water/foam and whether drilling has periodic stoppages. These affect operational planning and tool suitability. Do not imply that compressed air alone can resolve all geological or fluid-management issues.

17 — Duty cycle and schedule

Capture daily operating hours, continuous versus intermittent drilling, estimated project days, planned start date, shifts, standby needs and the consequence of interruption. Timing is a planning input, not a promised dispatch or delivery date.

18 — Fuel, electrical and operating support

Record diesel fuel arrangements, electrical supply if relevant, site access, refuelling restrictions, qualified operators and maintenance responsibility. Distinguish customer-provided utilities from services to be confirmed commercially. No assumed on-site operator, spare unit or guaranteed response.

19 — Transport and placement

Ask for access road condition, loading/unloading constraints, terrain, permitted equipment footprint, ventilation/exhaust limitations and distance from compressor to rig. A feasibility check precedes transport quotation and placement approval; customer-uploaded photographs are not a substitute for a safe site survey.

20 — Project location and jurisdiction

Request site locality and a separate optional location pin or coordinates with clear consent. Avoid collecting a private home address where district and project access details suffice. Any local permit, emissions, noise or worksite rule must be verified for the actual deployment jurisdiction and equipment.

21 — Safety information boundary

The website must not tell an unqualified customer to disconnect live high-pressure lines, open pressure vessels, bypass relief devices, modify booster settings or perform hazardous measurements. Provide a general stop-work/escalation note for uncontrolled pressure, suspected hose failure or injury risk; qualified site personnel control isolation and inspections.

22 — Required versus optional fields

Require contact route, request category, drilling application summary, project locality, acknowledgement of privacy notice and a meaningful free-text objective. Technical values may be marked unknown rather than fabricated. Conditional validation may require unit when a pressure, flow, diameter or depth number is entered.

23 — Field validation and unit normalisation

Preserve the original entered value/unit and store a separate canonical numerical value only after validated conversion. Do not silently convert gauge to absolute or mix standard and actual volumetric flow. Reject impossible numeric formats; flag implausible engineering values for reviewer assessment instead of silently deleting them.

24 — Attachment guidance

Accept approved PDF, common image and office formats only within server-enforced limits; publish permitted formats and maximum size after configuration. Useful files: rig/hammer specifications, compressor nameplates, approved site photographs, borehole summary, layout sketch and previous measurements. Never request passwords, personal identity documents or confidential customer drawings without necessity.

26 — Mobile-first intake

Use one-column labelled controls, visible units, short grouped steps and persistent entered values after validation errors. Provide camera upload with an ordinary file-picker alternative. Avoid sliders for precision measurements; allow unknown and do not require users to photograph unsafe equipment.

27 — Accessibility acceptance

All controls require programmatic labels, descriptive fieldset legends, keyboard navigation, visible focus, adequate target sizes, error summary with focus movement, live status announcements and a screen-reader-friendly review step. Test zoom to 200%, mobile portrait and attachment rejection.

28 — Consent and privacy

Separate necessary enquiry-processing consent/notice from optional marketing permission. Explain recipient roles, purpose, storage, retention, deletion request channel and third-party processors according to the actual policy and jurisdiction. Keep location and attachments out of analytics payloads.

29 — Routing and ownership

Assign intake owner by branch: drilling application technical reviewer, rental coordinator, equipment sales reviewer or service engineer as appropriate. A dispatcher must be configurable; no real named individual or mailbox is invented. Route technical ambiguity to engineering review before commercial recommendation. Record assigned role, status, due-review target if approved and escalation outcome.

30 — Durable status model

Use DRAFT → SUBMITTED → ACKNOWLEDGED → TRIAGE → NEEDS_INFORMATION / UNDER_TECHNICAL_REVIEW → READY_FOR_COMMERCIAL_SCOPE / NOT_SUITABLE / CLOSED. Distinguish receipt acknowledgement from engineering acceptance. Store status timestamp, actor, reason and customer-visible wording; restrict privileged transitions.

31 — Acknowledgement semantics

Show a reference only after the server confirms a durable record. Send an acknowledgement through the selected verified contact channel if configured; otherwise display an accurate on-screen receipt. Do not promise a response interval, availability, selection or price. Avoid leaking engineering attachments into email body.

32 — Failure and duplicate handling

On timeout, do not assert success. Provide a safe retry and reference lookup when possible. Use idempotency tokens to prevent duplicate submissions; protect against double taps and refreshes. If routing fails after persistence, show “received; routing pending” only when backend state confirms that distinction and alert an administrator.

33 — Technical review checklist

Reviewer confirms hole/bit/hammer identity, depth stage, required pressure at tool, flow basis, site conditions, hose/interface, operating duty, existing compressor capability and missing evidence. Record assumptions and incompatible values. Issue a request for clarification or a scope-ready brief; do not let the form calculate an automatic fit verdict.

34 — Preliminary engineering comparison

An illustrative request may state 18 bar(g) at the compressor and 17 bar(g) at the rig, but these are not comparable without simultaneous readings at a defined duty. Pressure loss is Δp = p_upstream − p_downstream for matched gauge readings at the same time. Tool inlet pressure and manufacturer air-consumption conditions must be verified before judging suitability.

35 — Flow and annular context

For a simplified annulus, area A = π(D_hole² − D_pipe²)/4 and superficial velocity v = Q_actual/A. This is a contextual screening relationship, not a universal acceptance threshold; actual in-hole gas volume, depth, cuttings, leakage, temperature and operating pressure matter. Technical calculation belongs on linked engineering pages, not the enquiry form.

36 — Engineering uncertainty ledger

Every derived or asserted parameter must have a source class: customer estimate, OEM datasheet, measurement, calculated, or reviewer assumption. Keep original units, date, location/boundary and confidence. Conflicts trigger NEEDS_INFORMATION, not a fabricated precision or automated compressor recommendation.

37 — Deliverable definition

A later technical response may propose a site survey, OEM check, equipment review or quotation scope. It must not be represented as a certified drilling design.

38 — Cross-page linking

Contextual links should point to the controlled Borewell Hub pages for annular velocity, drilling depth/selection, hammer demand and booster architecture only after confirming their live slugs.
