Field Development Plan — Anchor

Summary

The sanction-date concept is a subsea development served by a semisubmersible production unit.

Historical source snapshot, not a current operating-status assertion or a sanctioned engineering design. Missing inputs are preserved as unknown.

Revision history

RevisionDateWhat changed and why
Initial2026-10-19 Documented the reported development concept and evidence gaps to provide a field-level portfolio reference.
12026-10-20Kept conflicting depths unknown, distinguished source quantities and snapshot dates, and removed decimal padding to avoid inconsistent interpretation.

Engineering rationale

The sanction report describes subsea wells feeding a floating production unit in the Lower Tertiary Wilcox trend. This separates seafloor completions from surface processing; the cited selection does not by itself establish equipment qualification or installation feasibility.

Field parameters

InputValueSource and scope
Operator at source dateChevronS1: Operator named in the sanction announcement.
Reported development conceptsemisub_fpsS1: Opening development-scope paragraph states a semi-submersible floating production unit.
HostSemisubmersible floating production unitS1: Opening development-scope paragraph; subsea wells feed the FPU.
Water depth (m)UnknownS1: Sanction report gives 1,524 m; the lifecycle record gives 5,180 ft as a block-level estimate. An identical measurement location is not established; these depths remain unresolved, so the portfolio depth stays null.
Wells (scope stated below)7S1: Stage 1 scope is a seven-well subsea development; planned scope, not an operating inventory.
Designed peak capacity (boe/d)UnknownRequired input; not established by the cited evidence.
Reported oil capacity (bbl/d; not a boe/d plateau)75000S1: Design capacity is 75,000 bbl of crude oil per day; separate gas capacity is not converted to boe/d.
Recoverable resources (MMboe)UnknownRequired input; not established by the cited evidence.
Actual first-oil yearUnknownRequired input; not established by the cited evidence.

Architecture

The sanctioned subsea wells connect to a semisubmersible floating production unit. Detailed tree ratings, manifold arrangement and riser geometry require the design basis.

Well coordinates, manifold counts and interconnection lengths are required inputs for a detailed layout. Layout: NOT_EVALUATED; no assumed geometry is drawn.

Recommended concept shortlist

NOT_EVALUATED. The reported concept is documented above; a comparative ranking requires sourced screening limits and criteria weights.

Economics and execution

NOT_EVALUATED. No cost or investment return is inferred from facility capacity. Required inputs include scope-matched capital cost, operating cost, production profile, prices, discount rate and schedule. Equipment qualification and installation feasibility also require project-specific design evidence.

Known limits and way forward

This page records the 2019 sanction snapshot, not a current well inventory. The lifecycle Explorer reports first oil in August 2024; the cited sanction report only forecasts startup, so it cannot substantiate an actual first-oil year here. A startup source is required before replacing null. The published metric depth and lifecycle block-level estimate remain unresolved, so depth also stays null. Resource lower bounds are not exact reserve estimates. Obtain qualified equipment data before detailed assessment.
