MS Thesis Ideas

Here are some ideas that have good scope and purpose for master's projects.

1. Seismic P-wave velocity of near surface formations in NW Arkansas
2. Seismic S-wave velocity of near surface formations in NW Arkansas
3. Ground penetrating radar at Pedro site to image base of Miss carbonate mounds
4. Seismic P-wave anisotropy of near surface fractured Chattanooga shale 
5. Seismic S-wave anisotropy of near surface fractured Chattanooga shale 
6. Seismic P-wave refraction survey and geological correlation at a well site in NW Arkansas
7. Seismic properties of Boone regolith in various stages of weathering
8. Passive seismic recording of noise and extraction of shear wave velocities
9. Generate new type logs in selected OK oil and gas fields (Matson, possible TGS $ to support)
10. Convert Glenn Cole NE OK cross sections to Petrel 3D earth model, focus on Penn stratigraphy.
11. Volcanic source pipes in Pedernales 3D seismic survey
12. Elastic-porosity properties of Miss Chat in Osage Co, OK

AAPG Abstract Format

• Abstracts should cover the objectives, procedures, results and conclusions of the research and should be no more than 2,500 characters in length including spaces and punctuation. The title, authors and authors’ affiliations are not included in the character limit.
• Titles are required — they should be brief and state the topic.
• Abstract titles should not include company names and should be in sentence case.
• Student submissions are encouraged to all sessions.

Petra Projects

Some of our geology masters students do mapping projects using IHS Petra software. We try to capture these Petra project files so that future students can benefit from those who went before. Dr. Liner is the keeper of some Petra projects and Jamie Woolsey also maintains several.

Some Petra projects:

NE OK and NW AR (Kevin Liner, 2014)

Arkansas raster logs (Jamie Woolsey, 2015)

Western Arkoma Basin (Yueyang Wang, 2016)

Geology TA Application Process for Spring 2017

The Spring 2017 semester applications admissions and teaching assistantships will be due October 15th. The coming fall semester assitantships and positions have already been filled.  

To complete the application go to: 

https://application.uark.edu/

From there the grad school will assign you a login name and password. (give that a few days).

After that upload all necessary materials including statement of purpose and CV. Be sure to mention you are interested in a teaching assistantship

Teaching assistantships ($11,000 for 9 months for MS level, $13,000 for 9 months PhD level) in the department typically involve teaching undergraduate intro geology, and occasionally upper division undergrad classes. Research assistantships are dependent on your thesis advisor. If they have money for an RA, basically. 

Additional information can be found at the department website:

Basic Depth Conversion in OpendTect

Version: OpendTect 6.0.1

We routinely track a horizon in OpendTect to make time structure and horizon amplitude maps. But we would also like to make at least a basic contoured depth map. This is the simplest possible depth map since we are using a constant velocity for depth conversion. In areas of subtle structure it should be reasonably accurate. Here is the workflow:

1. This example is in the Wild Creek 3D survey, the horizon is a Lower Penn (LPenn) horizon, just below Oswego (Fig. 1) and the well is the Modica_1A-17. Even though this well is projected from 1.5 miles away, we will use it for this example. (Seismic data credit: Osage Nation Minerals Council; Well data credit: Spyglass Energy).
1. Numbers we need.... 
1. Wild Creek Survey = +1200 ft = SRD... seismic reference datum
2. Modica_1A-17  = +954 ft = KB ... kelley bushing
3. Event time at Modica Well = 0.533 sec = T ... reflection time
4. Event depth at Modica Well = 2575 ft = MD ... measured depth from KB
5. Event depth at Modica Well = 953 - 2575 = -1622 ft TVDSS ... depth sub-sea
2. calculate depth conversion velocity
1. V = 2*(MD - KB + SRD)/T = 2*(2575 - 953 + 1200)/0.533 = 10589 ft/s.... this is our constant velocity for depth conversion. The velocity will scale horizon times to depth from SRD. This depth will need to be subtracted from SRD to get TVDSS.
2. In the project tree add your 3D horizon and make the usual time maps
1. Horizon time structure with contours (Fig. 2)
2. Horizon amplitude with time structure contour overlay (Fig. 3)
3. On the top toolbar choose the Edit Attributes icon 
1. Choose the <All>/Horizon attribute for your horizon and data type and Z output. Name this attribute T_LPenn and Add As New (Fig. 4)
2. Choose the <All>/Mathematics attribute for your horizon and implement the depth conversion equation TVDSS = SRD - V * T / 2 and for 'T' use T_LPenn.  Name this attribute TVDSS_LPenn and Add As New (Fig. 5)
4. On the project tree under the LPenn horizon add the T_LPenn attribute, then right click on T_LPenn and select Save As Horizon Data... 
5. On the project tree under the LPenn horizon add the TVDSS_LPenn attribute, then right click on TVDSS_LPenn and select Save As Horizon Data... 
6. Add contours for T_LPenn (Fig. 6) and TVDSS_LPenn (Fig. 7)
1. Zoom near Modica well of TVDSS_LPenn color and contour map shows sub-sea depth near well is within 5 ft of the correct -1622 ft value (Fig. 8)
