Abstract
This paper discusses progressive construction and operational techniques which can be employed to minimize impacts from drilling operations in sensitive wetland environments. Some of the techniques to be discussed include:
Use of previously impacted wetlands for access routes;
Modified culvert design and placement criteria;
Specialized secondary and tertiary spill containment systems;
Closed-loop and containerized mud system;
"Environmentally friendly" substitutes for hydraulic fluids and lubricating compounds;
Integrated waste minimization practices; and
Innovative restoration alternatives.
Natural resource trustees have come to expect the use of such techniques when permitting access to custodial wetland areas. While some of these innovations add to the overall cost of the project, others may actually reduce total project cost. Combined with careful planning, these techniques can provide improvement in environmental protection at little incremental cost.
