INTRODUCTION Objective? Why I have chosen this project ? Who will benefit from the project ? What is Marcellus Shale and why it is
important? What is Utica Shale and why it is
important?
INTRODUCTION The recent change in drilling and production What is Horizontal Fracking ? What is Hydraulic Fracking ? What is the estimated resource from the
Marcellus Shale? What is the estimated resource from the
Utica Shale?

METHODOLOGY Source Data (EXL Spread Sheet) Algorithm
Data Preparation (ACCESS database)
» Create query1 from the joined MWELLHEADER table and Marcellus_tops table based on UWI and MTOP values (1795 RETURNS)
» Create query2 from the joined MWELLHEADER table and Marcellus_tops table based on UWI and MBOT values (1753 RETURNS)
» Create query3 that will change query1 to a table named WELLMTOP» Create query4 that will change query2 to a table named WELLMBOT
METHODOLOGY
Source Data Algorithm
Data Preparation (ACCESS database) Geoprocessing (ArcGIS)
• Add coordinate data to the WELLMTOP table (x y events) & save as a shapefile
• Join the rest of the table to it to include the fields MTOP and MBOT and name the combined shapefile WELLCOMB
• Add the fields MTHICK and MDEPTH • Use the field calculator to update the
records (e.g MTHICK = [MBOT]-[MTOP] )
Geoprocessing (ArcGIS)• Do Geostatistical Analysis from Geostatistical Wizard
using Kriging method for each fields to create a prediction map layer of polygon shape
– right click on the kriging layer – Click data >> export to vector
• Confirm that "GA Layer To Contour" dialogue box pops up allowing to make a polygon shape file of filled contours that showed both the prediction map and prediction standard error map for each field
• Use Natural Neigbour method for the Utica data– Reclassify raster output– Change raster to polygon
Geoprocessing (ArcGIS)
• Export the shapefiles out to Access database.
• The shapfiles are exported out in two forms
1. Text (use export shapefile to csv tool created by Jim Detwiler from my toolbox) Note: to append the geometry data
2. Table (dbase IV) Note: to append the attributes
MWELL.shpUWELL.shp MTHICK.shp
