Project Title: Integrated
approach to Improved Oil Recovery focused on Microbial
Enhanced Oil Recovery
Project Abstract
Technologies which are used to recover more oil during
Primary, Secondary as well as Tertiary stage are known
as Improved Oil Recovery (IOR). Biotechnology has played
a significant role in enhancing crude oil recovery and
environmental clean up. The Microbial Enhanced Oil Recovery
(MEOR) uses the injection of specific bacteria producing
gas, bio polymers or bio surfactants into the oil-saturated
layer to help recover residual oil. It is also used
for Removal of Paraffin deposits in Tubing and flow
line and pit cleanup.
In the Huff and Puff methodology, the well is shut down
for 21 days after injection of the microbial culture.
The aim of my project is to reduce this retention time
of 21 days and analyse the results by core flooding
analysis at the Institute of Reservoir Studies (I.R.S.),
with recently discovered Anaerobic Bacteria which is
active up to 90ºc, also it can work at high salinity
and vide range of pH.

Project Title: Managed Pressure
Drilling
Project Abstract
Managed Pressure Drilling is an innovative Drilling
technique is used to precisely control the annular pressure
profile throughout the well. It uses many tools to mitigate
the risks and costs associated with drilling wells by
managing the annular pressure profile. It is particularly
applicable for reducing the risk of a kick or lost returns
when drilling with a narrow window between pore pressure
and fracture pressure. The constant bottomhole pressure
method of managed pressure drilling uses annular frictional
pressure and choke pressure in addition to mud hydrostatic
pressure to achieve precise wellbore pressure control.
The economics of drilling wells is important as we drill
more wells. Drilling-related problems, including stuck
pipe, lost circulation and wellbore instability increases
the Non Productive Time. . So MPD improves the economics
of drilling wells by reducing drilling non productive
time (NPT).

Project Title: Fault Diagnosis
Using Model Predictive Control
Project Abstract
Model predictive control (MPC) schemes are typically
developed under the assumption that the sensors and
actuators are free from faults. Attempts to develop
fault-tolerant MPC schemes have mainly focused on dealing
with hard faults, such as sensor or actuator failures,
process leaks, etc. However, soft faults such as biases
or drifts in sensors or actuators are more frequently
encountered in the process industry. Occurrences of
such faults can lead to degradation in the closed loop
performance of the MPC controller. Since MPC controllers
are typically used to control key operations in a chemical
plant, this can have an impact on safety and productivity
of the entire plant. The conventional approach to dealing
with such soft faults in MPC formulations is through
the introduction of additional artificial states to
the model.

Project Title: Underbalanced
Operations
Project Abstract
This technology has been implemented to the formation
where conventional overbalanced techniques would cause
irreparable formation damage or in depleted formations
reservoirs to avoid / minimize formation damage and
to exploit the formation to its full potential. At present
many of the onshore reservoirs of India are in depleted
conditions with good amount of recoverable reserves.
Various issues involved in the underbalanced operations
will be investigated. Laboratory screening procedures
for evaluating the effectiveness of underbalanced drilling
for a specific application will be elaborated. I will
provide a detailed study in how to plan for Underbalanced
operations to achieve success in drilling the well.
The study emphasizes formation stability, well control,
environmental restrictions, minimum formation damage,
hydraulic analysis and guaranteed economic incentives.

Project Title: Design of Fracpack
technique for low to high permeable sand prone reservoir
Project Abstract:
Fracpack is a well stimulation technique most suitable
to wells with low and moderate permeability reservoirs
that do not provide commercial production rate even
though the formation damage is removed by acidizing
treatment or other methods. Due to Formation damage
and excess of undesirable sand production from unconsolidated
rocks ,the permeabilty of the reservoir formation is
impaired near well bore resulting in decrease of production
or production. It is a technique to improve well productivity
from low to high permeability reservoir. Combination
of Hydraulic Fracturing & Gravel Pack is called
Frac Pack Treatment.
My objective is to study the process and design a FRACKPACK
treatment for sand prone reservoir of low to high permeabilty
with particular reference to Western Onshore Fields
to increase productivity.

Project Title: Matrix Acidizing
(Development of Acid Formulation for Clay Rich Reservoir)
Project Abstract
Every hydrocarbon well undergoes to formation damage
during its life. Formation damage occurs during various
operations like Drilling, Completion, Perforation &
other operations. Formation damage reduces the productivity
of well, therefore it is very necessary to remove formation
damage.
There are various techniques to remove formation damage.
Matrix Acidizing is one of the good technique to remove
formation damage. Matrix acidizing is the technique
of removing near well bore damage.
My project will cover formation damage: Origin, Diagnosis
& Treatment along with laboratory experiments.
My project work will be focused on the acidizing of
clay rich reservoir. I will try to develop the acid
formulation for clay rich reservoirs.

Project Title: Design &
Development of fracturing fluid for High Temperature
High Pressure Reservoir
Project Abstract
Hydraulic fracturing of HTHP reservoir is one of the
challenges for enhancing the production of the reservoir.
At elevated temperature the fracturing fluid losses
it's stability and because of which the proppant carrying
capacity of the fracturing fluid is lost. For this design
and formulation in the fracturing fluid is done and
lot of research is going on for the successful fracturing
of the reservoir. The high temperature reservoir has
an effect on Crosslinking agent, with the increase in
temperature availability of borate ions is reduced due
to shift in boric acid/ mono-borate ion equilibrium.
Reduction of borate ion concentration will decrease
the number of effective crosslink in the fluids, causing
a loss of network structure. At elevated temperature
range 130-1500C the pH value must be around 12.0 and
this value obtained with buffering agent Sodium hydroxide.
This high pH value is essential at elevated temperatures.
