Helping Organizations Make Informed Site Decisions for Decades

Wotherspoon Environmental Inc. (WEI) has supported organizations across the energy sector since 1986. Our environmental consulting clients in Canada span oil and gas producers, pipeline operators, provincial regulators, and international petroleum companies. Rather than list every organization we have worked with over the decades, this page focuses on the industries we serve and a few examples of the clients who have trusted WEI with their environmental work.

Most of WEI's project history centers on upstream and midstream oil and gas clients, including producers, processors, and pipeline operators throughout Alberta, British Columbia, and Saskatchewan. Beyond the energy sector, WEI's client base has also included:

Many of WEI's longest relationships come from Alberta's oil and gas sector. Clients have included producers such as Suncor Energy and Canadian Natural Resources Limited, along with pipeline operators like Enbridge Pipelines Inc., Pembina Pipeline Corporation, and AltaGas Ltd. These partnerships reflect WEI's history of practical, hands-on environmental consulting for upstream oil and gas clients throughout the province.

WEI has also worked directly with the regulatory bodies responsible for overseeing environmental and operational compliance in Alberta, including the Alberta Energy Regulator (AER) and Alberta Environment and Sustainable Resource Development. These relationships have given WEI direct insight into what regulators expect from environmental management programs, which shapes how we support every client across the province.

WEI's environmental consulting clients in Canada are complemented by projects supporting international petroleum companies, including organizations such as PEMEX in Mexico and Petrobras in Brazil. WEI historically has also condcuted contingency planning and environmental operational training in regions including the Arctic, the United States, Central America, and the Middle East, adding a broader perspective to our environmental management approach.

Since 1986, WEI has grown its client base largely through referrals and repeat work. Many of our clients have worked with us across multiple projects over several years, from initial assessments through ongoing compliance support. This consistency reflects WEI's commitment to practical solutions and collaborative partnerships with every organization we serve.
