Konvicka #2 Project Summary – Buck Creek Prospect
Location: Lavaca County, Texas
Operator: MB Energy, LLC
Target Formation: Wilcox Sands (Migl, Burns, Allen Sands)
Spud Date: October 13, 2023
Total Depth (TD): 10,200’
API #: 42-285-34271
Project Overview
The Konvicka #2 well, located in the Buck Creek Prospect within the Hallettsville Field of Lavaca County, Texas, was drilled to test the Wilcox sands, targeting multiple pay zones, including the Migl, Burns, and Allen Sands. This well represents a key development in a historically productive area and highlights the potential for previously untapped intervals.
Key Operations and Results
Drilling:
Surface Hole: Drilled to 1,803’ and cemented with 76 bbls of returns to surface.
Main Hole: Drilled with a PDC bit to Total Depth (TD) of 10,200’ (Midway Shale) on November 2, 2023.
Maximum mud weight: 12.0 ppg.
Evaluation:
Mud Logging: Geotech mud logs recorded three significant shows, including:
Migl Sand (5,616’ – 5,623’): Oil odor with gas peaks of 173 units.
Allen Sands (9,560’ – 9,675’): Strong oil cut with gas peaks up to 473 units and bright yellow fluorescence.
Burns Sand (9,689’ – 9,743’): Maximum gas of 606 units with oil fluorescence.
Wireline Logs: Conducted two runs, confirming strong reservoir potential in the Allen and Burns sands. Logs correlated well with offset production from Howell Drilling’s Allen #1, which produced .938 Bcf gas and 282,534 Bbl oil.
Sidewall Cores: Recovered cores confirmed the presence of hydrocarbons with excellent permeability and porosity in the Allen and Burns intervals.
Primary Zones of Interest:
Burns Sand (9,688’ – 9,730’):
Strong gas shows (606 units) and high resistivity up to 21 ohms.
Gross Pay: 33 feet | Net Pay: 23 feet.
1st Allen Sand (9,560’ – 9,580’):
Good oil shows with a significant resistivity range of 3-23 ohms.
Gross Pay: 20 feet | Net Pay: 10 feet.
Inter-Allen Sands (9,584’ – 9,630’):
Multiple upward-fining sands not present in nearby wells.
Gross Pay: 46 feet | Net Pay: 23 feet.
Notable Observations:
The Allen Sands, which have historically produced substantial hydrocarbons in the area, showed strong potential in this well. The wireline logs and mud logging gas peaks confirmed the presence of oil and gas, with bright yellow fluorescence and excellent reservoir characteristics.
The Burns Sands recorded the highest gas show (606 units) and demonstrated significant net pay, suggesting robust production potential.
Additional “stray sands” at intervals like 9260’ and 9400’ provided smaller shows but were tight and non-commercial at this time.
Completion and Production Potential
The Allen and Burns Sands remain the primary completion targets based on logs, mud logs, and core analysis.
Next Steps: Completion plans include perforating the most promising intervals and testing initial flow rates.
Significance and Opportunity
The Konvicka #2 well confirms the potential for untapped hydrocarbons within the Buck Creek Prospect, particularly in the Burns and Allen Sands. Offset wells such as Allen #1 have demonstrated strong production histories, and this well’s results suggest similar, if not better, potential.
Conclusion
The Konvicka #2 well represents a successful step in further developing the Buck Creek Prospect. With multiple hydrocarbon-bearing zones confirmed and strong geological correlations to historically productive wells, this project showcases the continued opportunity in the Wilcox formation. Final completion and testing will determine the full production potential, but the results to date are highly encouraging.
