Mari Energies gas discovery in Balochistan has emerged as a significant development for Pakistan’s energy sector, highlighting renewed exploration momentum and confidence in domestic hydrocarbon resources. The discovery was made at the Tibri-1 exploratory well in the Kalchas South Block, located in the Dera Bugti district of Balochistan, and was officially disclosed through a notice submitted to the Pakistan Stock Exchange (PSX).
This breakthrough not only reflects Mari Energies Limited’s technical expertise but also reinforces Pakistan’s long-term strategy to reduce reliance on imported fuels and strengthen local gas supplies.
Overview of Mari Energies Gas Discovery at Tibri-1
The Mari Energies gas discovery was achieved through a joint venture operating in the Kalchas South Block. The block is operated by United Energy Pakistan Limited (UEPL), which holds a 46% working interest, while Mari Energies Limited owns 44%, and Dewan Petroleum (Pvt.) Limited (DPL) retains the remaining 10% stake.
Tibri-1 is the first exploratory well drilled in this block, making the discovery particularly important from an exploration standpoint.
Key Highlights of the Discovery
- Location: Kalchas South Block, Dera Bugti, Balochistan
- Well Name: Tibri-1
- Operator: United Energy Pakistan Limited (UEPL)
- Discovery Type: Natural gas
Drilling Details of Tibri-1 Exploratory Well
The Tibri-1 well was spudded on November 11, 2025, and drilled to a total depth of 7,170 feet. According to Mari Energies, the drilling campaign was executed smoothly despite historical challenges associated with exploration activities in the region.
This Mari Energies gas discovery marks a turning point, as the area had previously remained underexplored for an extended period.
Gas Flow Test Results from Dunghan / Sui Main Limestone
Initial testing focused on the Dunghan / Sui Main Limestone (SML) formation, a proven reservoir in Pakistan’s hydrocarbon landscape. The results were described as highly encouraging.
Test Flow Rates
- 11 MMSCFD at a 64/64″ choke, with a wellhead flowing pressure of 561 psig
- 6.5 MMSCFD at a 32/64″ choke, with pressure reaching 1,161 psig
These flow rates confirm the commercial potential of the Mari Energies gas discovery, while further testing is ongoing to fully evaluate reservoir performance and long-term production capacity.
Why This Mari Energies Gas Discovery Matters
Pakistan continues to face energy shortages and rising import bills, making domestic gas discoveries increasingly critical. This Mari Energies gas discovery contributes directly to:
- Strengthening local gas supply
- Reducing dependence on imported LNG
- Supporting industrial and power generation needs
- Improving energy affordability and security
From a national perspective, discoveries like Tibri-1 help stabilize the energy mix and enhance economic resilience.
Resumption of Exploration in a Previously Dormant Area
Mari Energies acknowledged that the Kalchas South area remained inactive for years due to security challenges. However, after the joint venture acquired Dewan Petroleum’s working interest in July 2023, exploration activities were revived with renewed focus and investment.
This strategic decision ultimately led to the successful Mari Energies gas discovery, demonstrating how policy support, security improvements, and private-sector commitment can unlock untapped resources.
Joint Venture’s Role in Expanding Pakistan’s Hydrocarbon Base
The discovery reflects the joint venture’s long-term commitment to expanding Pakistan’s domestic hydrocarbon portfolio. Mari Energies, alongside its partners, continues to invest in exploration and development projects that align with national energy priorities.
Working Interest Breakdown
- United Energy Pakistan Limited: 46%
- Mari Energies Limited: 44%
- Dewan Petroleum (Pvt.) Limited: 10%
Such collaborations enable risk-sharing, advanced technical execution, and faster development timelines.
Economic and Strategic Impact of Mari Energies Gas Discovery
Beyond technical success, the Mari Energies gas discovery carries broader economic implications:
- Increased employment opportunities in the region
- Enhanced investor confidence in Pakistan’s E&P sector
- Improved energy cost management for consumers
- Long-term contribution to national GDP
For Balochistan, in particular, new exploration success can play a role in regional development and infrastructure growth.
What Happens Next After the Discovery?
Mari Energies has confirmed that additional testing and evaluation are underway. These steps are essential to determine:
- Reservoir size
- Sustainable production rates
- Commercial viability
- Development planning
Once finalized, the Mari Energies gas discovery at Tibri-1 could be integrated into Pakistan’s gas supply network.
Conclusion
The Mari Energies gas discovery at Tibri-1 stands as a positive signal for Pakistan’s energy future. It highlights the value of persistent exploration, strategic partnerships, and renewed confidence in regions once considered challenging.
As further appraisal continues, this discovery has the potential to become a meaningful contributor to Pakistan’s domestic gas supply, reinforcing energy security and supporting sustainable economic growth.
