Apache is actively involved in discussing concerns about hydraulic fracturing, well construction, and onshore/offshore safety with investor institutions and governmental agencies. We have met with investors in Boston, New York City, San Francisco and Washington D.C. as well as European-based investors where we explain well construction needs, hydraulic fracturing risk evaluations and well safety requirements in our operations. We are also active in participating in industry technical forums, listening to industry and presenting Apache's achievements and developments in cutting-edge pad operations, fracturing performance, lower toxicity chemical developments and reduction of fresh water in our operations.
Horn River Basin
At the Horn River Basin in Canada, gas reserves under 6,000 forested acres are accessed from a six-acre pad.
Fresh water usage was reduced over 90 percent in the latest pad with a closed-loop fracturing system that uses salt water from a zone above the shale and returns that water to the source zone. The pads also enable accelerated learnings development and capture, reducing well numbers by 25 percent, while increasing gas recovery and reducing the time required for fracturing. Apache’s pad operations have achieved significant improvements in safety and reductions in emissions.
Hydraulic fracturing
A wide ranging hydraulic fracturing risk assessment has been completed by Apache and is being shared with the industry through the Society of Petroleum Engineers. The analysis covers emissions, seismicity, possible sources of pollution, chemical toxicity, and identifies technologies useful in monitoring or reducing risk. The paper is openly shared with environmental and industry interests.
