No, it isn’t “conservation groups” promoting the PXP slant drilling — it is the Environmental Defense Center and Get Oil Out. Other environmental groups are appalled by the EDC/PXP/GOO deal. So is at least one member of the Coastal Commission, and likely many others.
Don’t hang that albatross around the neck of all environmentalists and conservationists. Hang it where it belongs — on EDC and GOO.
