Undergraduate Student (Professional Communication Concentration)Department of EnglishTennessee Technological UniversityCookeville, TN 38505
Introduction
Problem: Directional Drilling Fluids may be damaging to the environment
Objective: To determine the effects of various Directional Drilling Fluids on the environment
Introduction (cont.)
Literature Review
Literature Summary: Drill Fluid Functions (Eide 1990) Operator Intentions (Wassenborg 2000) Toxicity of Drilling Fluids (Young 2006)
Water Based Oil Based
Possible benefit of drilling waste (Bauder et. al. 2005)
Government Regulations (Urquhart 1998)
Introduction (cont.)
Drill Fluid Uses: Drill head lubrication Cutting Transport waste to surface
Possible Problems stem from: Erosion Groundwater contaminants
Alternatives to Directional Drilling Fluids Miscellaneous
Some drilling fluids may aid tree-growth
Introduction (cont.)
Hypothesis: Directional Drilling Fluids have relatively no effect on the environment
Null Hypothesis: Directional Drilling Fluids have a significant effect on the surrounding environment
Goals: To determine the effects of Directional Drilling Fluids on the surrounding environment
Methods & Materials
Comparative observations used by NWS in United States “Tornado Alley” for comparing tornado damage zones (NWS 2002)
Visited 5 Horizontal Directional Drill Sites Recorded data on Data Form Analyzed data and pictures and formulated
conclusions
Results
Amount of Fluid Used (See Chart 1): Bore Length Soil Type Operator Skill Type of Fluid
Erosion rare-Drilling fluids have no more effect than a steady rain
Alternatives to Drilling Testing inconclusive, more testing needed
Focus on Groundwater contaminants Concentrate on single fluid type

Discussion
More Testing Needed Single Fluid Type Modified Experimental Design
Drill Fluid Functions (Eide 1990) Toxicity of Drilling Fluids (Young 2005)
HDD primarily uses Water-Based Fluids Oil Well drilling uses Oil-Based Fluids
Operator Intentions (Wassenborg 2000) Inexperienced operators use too much fluid Operators under severe timelines use too much fluid
