Environmentally Friendly Drilling Systems Program

Transcription

1 Environmentally Friendly Drilling Systems Program Awarded October 5, 2009 Technology Research, Development, Demonstration and Deployment (TRD 3 )

2 EFD Program A collaborative effort Industry Academia - Government Environmental Organizations Providing unbiased science to identify, develop and transfer critical, cost effective technologies for safe and environmentally friendly developments. SPONSORS ENVIRONMENTAL ORGANIZATIONS COLLABORATORS

3 EFD Alliance Universities and National Laboratories that have been involved

4 Issue / Concern Traffic Congestion Water Usage Chemicals Groundwater Protection Emissions / Flaring Earthquakes How Industry Addresses This Temporary pipelines, dust control plans, scheduling Put water use in perspective, treatment, recycling options FracFocus disclosure, EPA s Design for Environment products Spill containment systems, proactive measures Minimize flaring, waste heat to power equipment Pre- lease investigation and lessen disposal by recycling produced/flowback water

5 Frac Water Sourcing, Major Accomplishments Apache Irion County, TX z No fresh water used z 80,000 Truckloads off the road z Avoided water disposal fees and trucking costs z Dependable frac lower cost

6 Questions for Researchers 1. What is needed to increase the accuracy of emissions inventories and assess the effectiveness of emission- reduction programs? air water 2. What is needed to evaluate the emissions and potential health impacts? 3. How can flaring emissions be reduced in a cost effective manner? 4. What are the emissions during drilling, operations and after reclamation? 1. To what extent does the presence of natural gas contamination in a minority of drinking- water wells represent stray- gas contamination alone or, instead, the first sign of potential chemical contamination? 2. What are the constituents and concentrations contained in flowback / produced waters? 3. What are the best ways to treat water from oil and gas operations in order to maximize water recycling and reuse? 4. How can the volume of water needed for well stimulation be reduced? 1. To what extent and by what mechanism(s) does pressure in a fault increase with injection? 2. What faults are most likely to reactivate during injection? land 3. What is needed to validate predictive models (predict magnitude and occurrence) of induced seismicity? 4. Do horizontal drilling and hydraulic fracturing lead to higher stresses that require engineering safeguards to be reevaluated, particularly the mechanical properties of steel and cement?

7 Flaring Issues Magnitude in Million Cubic Feet (MCF) United States ,394 MCF North Dakota ,855 MCF Emissions VOCs, HAPs Field Trials Underway! Two interesting solutions being explored to capture natural gas from the flare ü Using natural gas to power turbine generator and offset site electricity ü Last Mile fueling solution - create CNG for transportation

8 Flowback What is it? First it is Produced Fluid not a waste Returning Fluid Composition: Frac base water and frac additives Waters from one or more formations A variety of salts and ions some stable, some not. Isotopes that can range from benign to low dose radioactive Solids of silica and many other minerals Hydrocarbon gas and liquids Other gases Consistency highly variable Early time gaining salinity Late time less saline?
