V316

Dear users of the Whitson+ external API,

We’ve just rolled out External API (EAPI) version 3.1.6, which includes several new capabilities for nodal analysis, well forecasting, and improved performance across core endpoints.

Here's a summary of what's new:

---

🆕 New Functionality

Nodal Analysis Support via API

You can now programmatically access full nodal analysis functionality through the External API:

• VLP Cases – Run, create, edit, and delete VLP cases
• Gradient Cases – Manage and execute gradient calculations
• Gas Lift Optimizer – Support for both single- and multi-well optimizer cases
• Multi-Well Optimizer Settings & Results – Retrieve and configure optimizer results at the project level

Autofit for Multiphase FMB

• Run multiphase FMB slope & intercept fitting for a single well or in bulk:

  ➜ POST /wells/{well_id}/autofit_multiphase_fmb
  ➜ POST /wells/autofit_multiphase_fmb

---

🔧 Improvements and changes

New Paginated Wells Endpoint: /wells_paginated

This faster, lightweight endpoint supports large-scale pagination (up to 10,000 wells per page).

• New fields now available:

  extrapolated_bot, fmb_type, liquid_loading_factor, owner, process_specific, rate_type_sim, sc_rates, well_type

• Removed fields (available via /old_wells_paginated):

  adsorption_input, last_production_date, production_data_plot_config, pvt_input

If you're using any of the removed fields, you can continue accessing them via the legacy /old_wells_paginated endpoint.

Autofit Control in History Matching (Numerical Model)

• The number_of_points parameter is now supported when using autofit, allowing greater control in history matching.

⏳ Coming Soon

Two new endpoints for efficient bulk BHP data access:

• /wells/bhp_inputs_no_deviation_survey
• /wells/bhp_input/well_data

We’ll notify you when these go live.
