The Impact of Lexin Resources’ Wells on Alberta’s Orphan Wells Count

The purpose of this article is to identify the impact of Lexin Resources' well inventory on the list of Alberta orphan wells, as published by the Orphan Wells Association (OWA) in March 2017.

This analysis is prompted by recent articles in the Calgary Herald (up to March 31), which refer to Lexin Resources as being shut down and put into receivership by the Alberta Energy Regulator (AER).

This analysis is a snapshot in time and because the number of wells and their status may change over time, this article refers to the counts in the past tense. Please note the disclaimer at the bottom of this post.

The Context of Alberta Orphan Wells:

  • There were 4948 orphan wells in Alberta as of March 2017. Most of those (4250) were classified as having a next step "To Abandon". This means they are to be permanently cut and capped (sealed).
  • The remaining 698 wells were classified as having the next step "To Reclaim". This means the land surrounding the well is to be remediated and reclaimed.
  • The blue circles on the map above show a broad distribution of orphan wells across Alberta, with pockets of concentration evident.
  • To have a well properly "Abandoned" and "Reclaimed" (in AER parlance) is a good thing; it's like saying the well has been properly decommissioned.
  • The OWA does this work on behalf of the industry when well licensees (companies) become defunct (such as going bankrupt). In other words, the wells have become ownerless and the OWA steps in to guide them through end-of-life.
  • The total number of orphan wells in Alberta increased from 1961 wells in Sep 2016 to 4948 wells in Mar 2017, a 152% increase over that period.

Lexin's Orphan Wells: 

  • The AER stated on March 21  that "care and custody of Lexin’s assets remain with the Orphan Well Association and identified working interest participants."
  • The orange circles on the maps above approximate the location of the wells. This is done by identifying Lexin's wells in each Alberta township and then plotting a circle in the centre of those townships (ie. based on the AB Township Survey). The bigger the circle, the greater the number of Lexin wells in the township.
  • The large increase in Alberta's orphan wells in March was mainly due to Lexin's 2113 wells (representing ~43% of the total amount.)
  • All of Lexin's wells appear to be classified by the OWA as having a next step "To Abandon".
  • The majority of Lexin's wells were located south of Calgary, though there were a few pockets elsewhere in the province.
  • The chart below indicates that Lexin's amount of orphan wells "To Abandon" is significantly more than the next highest, that being 274 wells, once belonging to Canadian Coyote Energy.
  • The Alberta Energy Regulator (AER) has indicated that some of Lexin's wells could eventually be transferred to other operating companies. As in, some of the wells will not remain orphan wells and will take on new owners.

Definitions and Interpretation: 

  • *Orphan Wells" are wells associated with Defunct Companies, which "are licensees that are deemed defaulting working interest participants by the AER pursuant to Section 70(2)(b)(iii) of the Oil and Gas Conservation Act."
  • The OWA provide updates to their data about once a quarter.
