مسار البئر ومنع التصادم

في جملة واحدة

Checks the planned and actual well path against every other well on the pad, with the survey uncertainty included.

المشكلة

On a crowded pad, well-path data lives in several systems with different reference datums, and the anti-collision check depends on someone having loaded the right offset surveys into the right software.

A collision is a well-control event and a potential loss of two wells.

كيف تعمل

All surveys are normalised to a single geodetic reference and stored against the well master record. Separation factor is computed with ISCWSA error models appropriate to each survey tool, so an old single-shot survey carries its real uncertainty rather than an optimistic one.

Alerts fire on the planned trajectory before spud and on the actual trajectory per survey during drilling.

البيانات المطلوبة

  • Definitive surveys for every well on and near the pad, with tool type and run intervals
  • Wellhead coordinates and the common geodetic reference
  • Planned trajectory for the new well
  • Casing and completion geometry for offset wells

ما الذي تحصل عليه

  • Separation factor and ellipse-of-uncertainty plots per offset well
  • Travelling-cylinder view updated per survey
  • Pre-spud anti-collision report for the drilling programme

ما لا تستطيع فعله

The calculation is only as trustworthy as the offset survey metadata, and in brownfields the tool type and run interval for older wells is frequently unrecorded. Where metadata is missing we apply the most conservative error model, which produces alerts that are pessimistic rather than wrong — but it does mean legacy pads generate more warnings than a newer field.
