Your assignment for this project is to design a drilling assembly consisting
of drill pipe and drill collars after gathering data for a known field. The
information from surrounding wells and fields can be used to design the drill
string and selecting the rotary drilling rig. The site selection process should
consider the available data from offset wells in terms of formation properties and
should have a minimum depth (TVD) of 8000 ft.
Report the results for rotary drilling rig capacity and/or limitations to
drill a new well at the selected field. The major part of the report should
include the calculations related to the forces on the drill string.
Report should contain a statement of the problem and the limitations and
safety factors used for the design. Include all applicable constraints like social
and environmental impact of the selected site in the report. Use appendix for
detailed calculations and specifications.
Some examples of data you can use in the preparation of your report are site
location and surface maps, formation contacts (or thicknesses), completion interval
and type, fresh water and coal seam zones to be drilled through, type of fluid
produced and their analysis, formation pressure, fracture gradients, well logs,
production tests, and other related information on the subsurface. You may not have
all the data listed here. Attach copies of all documents used in the preparation of
final report in “pdf” format with proper name convention. Keep a copy of your
documents and data for new assignments of this class.
Please keep me informed on your progress and see me or class TA if you need
additional assistance. Also, a spreadsheet file will be posted on eCampus within
“Homework” folder for you to enter your data. Submit it after saving the
spreadsheet file with the name convention given in syllabus no later than February
14. Your final report should be submitted in MS Word format on the “Turnitin”
assignment page. Additional links will be provided for submitting supplemental
documents. Pictures or photos of write ups and/or equations are unacceptable in
the report.
Use handouts and available catalogs for equipment selection. Each individual
is responsible for submitting a final report. More information regarding the
report format and grading rubrics will be posted.
