Pakistan Petroleum Limited (PPL) has made another gas discovery in Sindh, bringing fresh hope for Pakistan’s energy sector. The discovery was reported from the Sawan Field in District Khairpur through the exploratory well Sawan North Deep-1 ST-1. The development is important because Pakistan continues to face a shortage of locally produced natural gas and remains dependent on costly energy imports.
The latest discovery was made by the Sawan Joint Venture, in which PPL is one of the major partners. According to the company’s disclosure, the well reached a measured depth of 14,017 feet and was tested after drilling and completion work. The test produced around 0.30 million standard cubic feet of gas per day.
Although the initial gas flow is not very large compared with some other discoveries in Pakistan, the find has wider importance because it confirms that the area still has gas potential. It also gives exploration companies more information about the underground rock formations and may encourage further drilling in the region.
New Gas Discovery in Khairpur
The discovery was made in the Sawan Field, which is located in District Khairpur, Sindh. The well used for the exploration was named Sawan North Deep-1 ST-1, also known as SND-1 ST-1.
PPL announced the discovery through a notice submitted to the Pakistan Stock Exchange. The company said the Sawan Joint Venture had discovered hydrocarbons through the exploratory well. The main target of the drilling work was the Lower Goru Formation, particularly the A-Interval sands.
The Lower Goru Formation is an important geological formation for oil and gas exploration in Pakistan. Several discoveries in Sindh have been linked to formations in this region. Finding gas in another part of the formation gives companies more reason to study the area and search for additional resources.
PPL Holds a Major Share in the Project
The Sawan Joint Venture includes several companies working together on exploration activities. UEP Beta is the operator and holds a 25 percent working interest. Pakistan Petroleum Limited has a 30 percent working interest, while PPL Europe E&P Limited also holds 10 percent.
Prime AEP Limited has another 30 percent working interest, and Government Holdings (Private) Limited holds the remaining 5 percent.
This type of partnership is common in the oil and gas industry. Exploration requires large investments, technical skills and careful planning. By working together, companies can share the cost, technical knowledge and risks involved in drilling deep wells.
For Pakistan, such joint ventures are also useful because they allow local companies and their partners to continue exploring domestic resources without depending on a single company for all the investment and technical work.
Well Drilling Started in 2024
The drilling of Sawan North Deep-1 began on September 16, 2024. The well was eventually drilled to a measured depth of 14,017 feet, making it a deep exploration project.
Drilling such a well is not a simple process. Before the drilling starts, companies study geological information, seismic data and other technical details to decide where a well should be drilled. Once drilling begins, the team continues to study the rocks and formations encountered underground.
In this case, the drilling results and wireline logs provided information about possible hydrocarbon-bearing zones. After the well was completed, the promising sections were tested to find out whether they could produce commercial quantities of gas.
Gas Production Recorded During Testing
Testing of the well produced approximately 0.30 million standard cubic feet of gas per day. The test was conducted at a flowing wellhead pressure of around 100 pounds per square inch gauge, using a 128/64-inch choke.
This initial test result is important because it confirms the presence of gas in the targeted geological area. However, an exploration discovery does not automatically mean that large-scale commercial production will begin immediately.
Companies normally carry out further technical and economic studies after a discovery. These studies help determine the size of the reservoir, the quality of the gas, production potential and the cost of developing the field.
Therefore, the latest discovery should be seen as an important exploration success rather than an immediate solution to Pakistan’s gas shortage.
New Exploration Method Used
One of the interesting parts of the project is the exploration method used for Sawan North Deep-1 ST-1.
According to PPL, this was the first well in the Sawan area to be drilled using an exclusive sequence stratigraphic trap evaluation approach. The successful discovery has helped support the geological idea behind the exploration strategy.
In simple words, this approach helps geologists understand how layers of rocks were formed and where oil or gas may have become trapped underground.
The success of the well means the companies now have more confidence in this geological concept. It may also help them identify other locations where similar underground conditions exist.
Why the Discovery Matters for Pakistan
Pakistan has been dealing with a long-running energy challenge. Natural gas is used by homes, industries, power plants, fertilizer companies and other businesses. At the same time, local gas reserves have been under pressure because production from older fields has declined.
When local gas production is not enough to meet demand, Pakistan has to depend more on imported fuels, including liquefied natural gas. Imports can put pressure on the country’s foreign exchange reserves, especially when international energy prices are high.
New domestic discoveries can help reduce this pressure over time. If a discovery is developed successfully, locally produced gas can become part of the country’s energy supply.
However, the impact depends on the size of the reserves and how quickly production can begin. Exploration success is only the first stage. More work is needed before the gas can reach consumers.
Sindh Remains Important for Gas Exploration
Sindh has long been one of Pakistan’s most important regions for oil and gas exploration. The province contains several major oil and gas fields and has attracted exploration companies for many years.
The latest PPL discovery in Khairpur adds to the province’s importance in Pakistan’s energy map. Earlier discoveries in different parts of Sindh have also shown that the province contains significant hydrocarbon potential.
PPL has carried out exploration activities in several areas of Sindh. The company has also been involved in other recent discoveries and projects aimed at increasing domestic oil and gas production.
The company’s 2024 discovery at Pateji-X1 in the Shah Bandar Block, for example, produced both gas and condensate during testing. That well recorded a flow rate of 12.4 million cubic feet of gas per day and 196 barrels of condensate per day from the C-Sand layer.
These discoveries show why Sindh continues to attract attention from Pakistan’s exploration and production companies.
What This Means for Energy Security
Energy security means having a reliable supply of energy at a reasonable cost. For Pakistan, improving local oil and gas production is one way to strengthen energy security.
Every successful domestic discovery can add to the country’s resource base. While one well may not completely change the national energy situation, a series of successful discoveries can make a meaningful difference.
More local gas can also support industries that depend on natural gas for their daily operations. Fertilizer plants, factories, power producers and other businesses need a steady supply of gas to continue working.
If new discoveries are developed efficiently, they can also reduce the country’s need for some imported energy. This could help save foreign exchange and support the wider economy.
Discovery Does Not Mean Immediate Large-Scale Supply
It is important to understand the difference between discovering gas and starting commercial production.
When an exploration well finds gas, engineers first need to understand the reservoir. They may conduct additional tests and studies to estimate how much gas is present and how easily it can be produced.
The company must then decide whether developing the discovery is financially practical. This can involve building pipelines, processing facilities and other infrastructure.
The gas also needs to be connected to the country’s distribution system before it can reach consumers.
Because of these steps, the latest PPL discovery should not be expected to immediately increase household gas supply. Its long-term value will depend on further evaluation and development.
A Positive Signal for Future Exploration
Perhaps the biggest value of the Sawan North Deep-1 ST-1 discovery is the information it provides for future exploration.
Oil and gas exploration is based heavily on geological understanding. A successful well can confirm that a particular geological idea is correct. Once that happens, companies can study nearby areas and look for similar opportunities.
PPL said the success of the well has validated the geological concept used in the exploration and opened new exploration possibilities in the Sawan region.
This could encourage additional exploration activity in the area. If further wells are successful, the overall importance of the discovery could become much greater.
Role of PPL in Pakistan’s Energy Sector
Pakistan Petroleum Limited is one of the country’s major oil and gas exploration and production companies. Its activities include searching for hydrocarbons, developing discoveries and producing oil and natural gas.
PPL has been active in Pakistan’s energy industry for decades. The company operates and participates in several exploration blocks and works with different partners on oil and gas projects.
Its latest discovery in Sindh shows that the company continues to invest in exploration despite the challenges involved in finding new domestic resources.
Exploration is always uncertain. Companies can spend large amounts of money drilling a well without finding commercially useful quantities of oil or gas. This makes every successful discovery important for both the company and the country.
Future Prospects for the Sawan Area
The latest discovery could increase interest in the Sawan region. The successful use of the geological approach provides useful information for future drilling plans.
More exploration may help companies understand whether the gas found in Sawan North Deep-1 ST-1 is part of a larger reservoir or whether similar gas-bearing zones exist nearby.
Further drilling and technical studies will be needed before the full potential of the area becomes clear.
If additional discoveries are made, the Sawan Field could become even more important for Pakistan’s domestic gas supply.
Conclusion
Pakistan Petroleum Limited’s new gas discovery in the Sawan Field of District Khairpur, Sindh, is a positive development for Pakistan’s energy sector. The Sawan North Deep-1 ST-1 exploratory well reached a depth of 14,017 feet and produced around 0.30 million standard cubic feet of gas per day during testing.
The discovery is especially important because it supports a new geological exploration approach in the Sawan area and may open the door to further exploration.
Pakistan still faces a major challenge in meeting its growing energy needs. Local gas production can help reduce dependence on expensive imports, support industries and improve energy security. However, the actual impact of this discovery will depend on further evaluation, development and commercial production.
For now, the PPL discovery is a promising sign that Pakistan still has untapped gas resources. Continued exploration, better technology and investment in domestic energy projects will be important if the country wants to make better use of these resources and build a more secure energy future.
