Gas Leaks from Abandoned Wells Pose Explosion Risks to Miri Residents

Gas leaks originating from abandoned oil wells present a significant explosion hazard to Miri residents, particularly in areas like Canada Hill where a hole is believed to be emitting liquefied natural gas. The Sarawak Petroleum Contractors Association (SPECA) has strongly advised the public to stay clear of these sites due to the potential dangers.
Potential for Explosion Due to Gas Emission

A recent discovery of a foaming hole near Canada Hill in Miri, suspected to be a leak of liquefied natural gas, highlights the inherent risks associated with abandoned oil wells. SPECA president Datuk Rahman Lariwoo stated that such emissions, likely stemming from waste materials of defunct wells, are hazardous and could lead to an explosion.
Safety Advisory and Proposed Mitigation Measures

In response to these concerns, SPECA is urging Miri residents to avoid abandoned oil well locations for their own safety. The association is prepared to engage with local authorities to discuss the identified dangers and has proposed a plan to mitigate risks. This includes the identification and fencing of all 624 abandoned oil well sites in the Miri area, accompanied by clear public warnings to stay away from these potentially dangerous locations.
Responsibility and Costs of Remediation

While the exact entity responsible for the abandoned wells around Canada Hill remains unclear, SPECA has indicated a readiness to submit proposals for the repair and sealing of leaks. The association noted that while fencing the numerous abandoned sites would not be excessively costly, the actual work of repairing and securely sealing the wells themselves would incur higher expenses. The cost of sealing an onshore well is considerably less than that for offshore wells, which can range from RM120 million to RM150 million per well.
