Gas Well Review

Kees Veeken 
5 days

Business context

Gas well performance must be reviewed prior to yearly business processes that rely on a consistent and credible production forecast, reserves estimate and activity plan. Such reviews are best carried out in a structured manner that is applicable to all gas wells.

The objectives of this course are (1) to embed a structured gas well review process by carrying out actual gas well reviews, and (2) to explore the resulting surveillance and capacity needs for a representative collection of wells. The 5 days course should allow reviewing 5-15 wells depending on the well and data specifics, and on the number of participants.

This course builds upon the skills and tools of the Gas Well Performance Training and can be scheduled consecutively.

Who should attend

Production engineer, surveillance engineer, completion engineer, reservoir engineer, production programmer, production operator

Course content

  1. Review data: assess and judge availability and quality of well, reservoir, production and surveillance data.
  2. Review inflow, outflow and reservoir performance: first quantify, then identify changes and inconsistencies over time that reveal threats or highlight opportunities.
  3. Review surveillance and capacity plans: compare, rank and select well and surface measures that monitor, restore, sustain or improve performance
  4. Report results: capture and summarize as input for relevant business processes.

Learning, methods and tools

The course hinges on data from actual wells selected by participants. A list of data requirements will be shared beforehand so data can be submitted and then checked to ensure that the review sessions will be instructive and productive.

The review utilizes the Excel worksheets from the Gas Well Performance Training and, where available and requested, other gas well performance software such as PROSPER. The inflow, outflow and reservoir performance are captured by a universal set of parameters that allow easy comparison in time and between gas wells. An additional worksheet is introduced that generates the incremental production forecast and economic parameters for each capacity measure.

The participants will be working in small groups, tackling both the same wells for learning and different wells for achieving results. The technical feasibility and design of the proposed surveillance and capacity measures will be discussed plenary to ensure that the results of the review are realistic.
