 Welcome to the land of Mountains, Hills and Terai. We will explore more about this land facts, information and news about this amazing land...

Status of Natural Gas in the Kathmandu Valley


The “Kathmandu Gas Project” was established in 1978 for the exploration of natural gas beneath the ground of the Kathmandu Valley, with the support of the Department of Mines and Geology and the Japanese aid agency JICA. This project was the first to initiate research and study on the possibility of natural gas within the Kathmandu Valley.

Subsequently, with technical and financial assistance from the United Nations Development Programme (UNDP), around 26 square kilometers were divided into 3 blocks, and a total of 14 gas wells were drilled on various dates. According to the studies, tests, and exploration reports conducted in different phases, the findings include:

  • Gas Porosity: 35%

  • Gas-Water Ratio (0.4): 1:2.5

  • Reserve Thickness: 85 meters

  • Gas Reserve:

    • Block A: 47.6 million cubic meters (Proven)

    • Block B: 170 million cubic meters (Probable)

    • Block C: 100.8 million cubic meters (Probable)

The places and dates of gas well drilling conducted under this project are as follows:

Gas Distribution

Around the year 1983, with the support of JICA, a gas bullet with a capacity of 500 cubic meters was constructed in Teku, Pachali of Block A as a trial. Gas from Well No. 1, 2, and 3 was stored in the bullet through a pipeline system and distributed via pipelines to nearby government offices and hospitals for several years.

GEOLOGICAL HISTRORY OF NEPAL HIMALAYA

  

Himalaya was formed by the collision of Indian Plate with Eurasian Plate around 55 million years ago.

The major events in the geological history of Himalaya are well recognizable in Nepalese sector. They are: Sedimentation in the Purana Sea, Pan African Diastrophism, Sedimentation in Paleothethys, Hercynian Diastrophism, Gondwana Sedimentation, Sedimentation in Neotethys, beginning of Himalayan Orogeny, formation of foreland basin and tremendous rise of Himalaya

A. Precambrian Events

Deep and Shallow marine sedimentation in Purana Sea.

Wide distribution of Precambrian rocks in LH and HH.

Very early during Paleozoic, there was a very wide sea covering the vast territory of LH and the central and northern parts of India.

Deep marine sedimentation in early phases and shallow marine deposition in later phases dominantly of carbonate succession with stromatolites.

B. Paleozoic Events

It includes Pan African Diastrophism, Sedimentation in Paleothethys, breaking of sedimentation due to Hercynian Diastrophism and Early Gondwana Sedimentation

Pan African Diastrophism: long cycle of Purana Sedimentation came to end towards the close of early Cambrian, sea was forced to recede form LH and sedimentation was interrupted. Intrusion of Cambrian Ordovician granites.

Sedimentation in Paleothethys: Sedimentation was restarted in Tethyan Himalayan zone with abundant marine fossils of barchipods, corals graptolites etc.

Hercynian Diastrophism: Interruption of sedimentation in TH (regional unconformity). Rifting and volcanism in LH and widespread glaciation.

Early Gondwana Sedimentation: at the end of Paleozoic era along with some explosive volcanoes in rift valleys.

 

C. Mesozoic Events

Sedimentation in Neotethys and continetal sedimentation of Late Gondwana.

Sedimentation in Neotethys: Tibetan landmass in North was broken away due to rifting and opened new sea called Neotethys between India and Tibet.  Deep marine sedimentation in northern part excluding Nepal Himalaya.

Sedimentation of Late Gondwana:  continental sedmentaion of Upper Gondwana unconfromably over Lower Gondwana.

D. Cenozoic Events

Disappearance of Neotethys: due to plate collision emplacement and squeezing of sea floor rocks. Formation of elongated basins in North and south and rise of Himalaya.

Formation of MCT about 21 Ma. Around 25 to 15 Ma  Granites and migmatites in TH and HH. Also development of Nappe and Klippe.

Formation of MBT about 18 to 20 ma and Siwalik Basin.

Formation of HFT, Dun Valley and Terai basin.

 

 

Now or Never: The Reform for Nepal Public Governance

 After the September 8 and 9 revolution, Nepal is on the midway between a new sunrise or the same dark era of old governance.

Many voice have been loud now for the complete reform of the executive and legislature body of the nation. Within this the complete reform of the government bodies, ministries and other administrative bodies of the government is the most. So this is the best time to implement reforms to reduce Nepal's current government expenditure.

The basic and foremost transformation is needed in Health, Education and Employment.

The current lower house parliament consists of 275 members. As parliament members mole is to formulate policies not meant to develop infrastructure. One representative per district is enough. So, 77 parliament members representing each district is enough for parliament. The national assembly or the Rastriya Sabha consists of 59 members. It can be restructured to include experts from various fields that cannot be represented in the parliament with 23 members making total size of legislature 100 only which will drastically cut off current size of 334.

Bureaucracy, the permanent government of a nation is the area which needs a complete reform with citizens oriented service in frontline rather than the old hectic and lengthy service. Single Window System, the complete output of any service from a single point where the initial application is summitted, is necessary in the public governance of Nepal. Every government office should reform their working motive with service delivery and transparency first. The government offices should be reorganized with simple and efficient organizational structure replacing the old bulkier structures. 

The current 22 ministries in the federal government are enormous size for the efficient federal mobilization. So, there is quick need of  reformation of the federal ministries and their scope of work by releasing respective works to province and local governments. About 14 ministries in federal government are sufficient to address the federal powers.  

Also there has been a debate over size of Nepalese Army But the current scenario after the revolution has shown the importance of military force in the nation. So, leaving the debate over the size of Nepal Army, there has been a need to reorganize and restructure the Nepal Police and APF into one unit.  These two units should me merged and made efficient with special forces within them for general public security and emergency securities. 

Academic Chancellor: the single step measure to right track the Nepali Universities.

Currently, the Prime minister of Nepal Government is the Chancellor of all the Universities of Nepal. So, even to pass the policies, programs, budget and even small administrative decision, the political leadership has been very influential in the Universities, dragging the overall higher education system of the nation behind.

The political leadership have been heavily linked even in appointment of academic position breaking the merit. This has been the blunder in the Universities of Nepal. And also the approval from the politician even in small decisions and appointment has not only delayed the whole educational calendar, but led the universities into their darkest era. The political party in government have been dominant to appoint their close persons in every post and the student unions form the opposing parties have been the face of opposition to create violence and disturb the regular works in the name of students making universities the open battel ground for the parties.

So, the one step solution by removing this policy to appoint chancellor from within the academia of the University is the first, foremost and a must step to change the track of Higher education in the country. 

Also, Nepali Universities should modify their curriculum with the motive of Earning while Learning for the youths to take studies and economic life side by side which can be a revolutionary approach to reform Higher Education of Nepal.
