Exploratory drilling is
being taken up by deploying DTH & Rotary rigs of 200 m to 300 m drilling capacity in
different geological formations i.e. hard rocks, sedimentary and unconsolidated sediments
for identification of potential aquifers, demarcation of their vertical and lateral
extensions, delineation of fresh/saline water aquifers. Systematic hydrogeological tests
for evaluation of potentialities of different aquifers, determination of spacing between
tubewells etc. The above data is essential for planned scientific development and
management of this vital resource. |
Till March
2004, 600 Expl. Wells has been drilled by CGWB under Normal Expl. Programme, drilling at
222 sites was taken up under Accelerated Expl. Drills Programme and special assistance in
the drought affected areas of MP during the year 2001-02. 50 Expl. Wells have been
constructed in Dewas and Shajapur district in the year 2003-04, Successful exploratory
tubewells have been constructed in different hydrogeological terrains. Exploratory
drilling has established the presence of potential aquifers in basalts, Gondwanas,
Vindhyan sandstone, Granites apart from the limited alluvial terrain of the state. The
district wise details of boreholes drilled by CGWB, rigs are presented in table and under
accelerated exploratory Programme are given table. The following are the highlights and
achievements of exploration taken up in Madhya Pradesh.
 |
Occurrence of promising aquifer zones was established in the basaltic
terrain of Narmada Sagar area falling in Khandwa, Khargone and Dhar districts. Potential
zones were also identified in the Bagh beds and tubewells yielding upto 1000 LPM were
constructed in an area which was a water scarcity area.
|
|
In Gambhir basin falling in Indore district, occurrence of promising
aquifers in basalts was established yielding upto 700 LPM.
|
|
Special exploratory studies in the Kuteshwar limestone area of Katni
district established the occurrence of cavernous limestone and strong possibilities of
seepage of reservoir water through these caverns resulting in the inundation of limestone
quarries.
|
|
Exploration was taken up in the fluoride affected areas of Shivpuri and
Chhindwara districts and aquifers having fluoride within the permissible limit and having
excess fluoride were identified so that PHED could tap the safe aquifer for drinking water
supplies.
|
|
Exploration in Mandsaur district established the occurrence of saline
aquifers at deeper levels. The position of saline-fresh water interface was also
established.
|
|
High yielding wells were constructed in many urban areas of the state.
These wells solved the drinking water crisis in water scarcity towns.
|
|
It was established that the Gondwana sandstones and lametas of Katni and
Jabalpur districts respectively have promising fresh water aquifers. At the same time it
has also been established that the basalts of Jabalpur are not potential.
|
|
Free flowing artesian aquifers were delineated in Shahdol district along
with high yields of the order of 2336 LPM.
|
|
Exploration in Bhind and Morena districts established the presence of
saline aquifer at deeper levels. In Phuph area of Bhind district, the state Govt. had
drilled at 42 locations without successfully locating promising aquifers. CGWB constructed
two exploratory wells and subsequently under the guidance of CGWB based on its exploration
data, the state Govt. could construct several successful wells.
|
|
The exploration in the chronically drought affected area of Khandwa
district provided success to the resident in the form of 14 successful wells out of which
4 were of A category.
|
|
Drilling at 222 locations was taken up under Accelerated Exploration
Programme for drought assistance to the state government and the 174 successful wells
provided relief in the drought affected areas of the state during 2001-2002. Further, 50
wells were also constructed under AEP in Dewas and Shajapur district in 2003-2004.
|
|
In most of the districts of Madhya Pradesh, layers of soft collapsible
formations are encountered in-between layers of hard rocks making it difficult to
negotiate these layers during drilling operations. Moreover for successful completion of
wells in such formations, it is necessary to lower full length/part assemblies in almost
every well. Several innovative approaches have been devised and attempted by the
engineering officers and drilling crew of the division-XII to negotiate these collapsible
formations and complete successful wells in these formations.
|
|
In alluvial area of Hoshangabad district, a well drilled at MAF Babai
site, coarse-grained alluvial deposits comprising boulders, pebbles and coarse sand were
encountered. The sieve analysis of samples indicated the possibility of constructing a
naturally developed well and it was decided to construct a naturally developed well at the
site on experimental basis. The well was completed without any gravel pack and
successfully developed adopting concentrated development method with the use of specially
designed, locally fabricated double packer surge block-cum-isolation tool and
Sodium-hexa-meta-phosphate as deflocculating agent.
|
|
By and large, the villages referred to CGWB by the state govt., the
problem villages where the state govt. has not been successful in constructing tubewells.
However, CGWB based on its earlier exploration, using the best techniques available, has
been successful in constructing tubewells to not only generate scientific data but also
provide assistance to the state govt.
