## ANSWER

पेट्रोलियम और प्राक ृ लिक गैस मंत्रािय में राज्य मंत्री (स्विन्त्त्र प्रभार) (श्री धमेन्त्र प्रधान)

## MINISTER  OF  STATE  (I/C)  IN  THE  MINISTRY  OF  PETROLEUM  &  NATURAL  GAS (SHRI DHARAMENDRA PRADHAN)

- (a) & (b). In the E&P (Offshore/Onshore) oil establishments, total 44 numbers of accidents/incidents have been reported by Oil Industry Safety Directorate ( OISD) since the year 2014 including Gas leakage in Mumbai high. The details of accidents including gas leak which took place  in  onshore/offshore  installations  along  with  their  root  cause  are  furnished  in  Annexure-I. There were total 15 fatalities in all these 44 incidents/accidents.

As  regards  the  steps  taken  by  the  government  to  find  out  the  cause  of  leakage,  it  may  be mentioned  that  investigation  of  any  incident  is  undertaken  by  the  concerned  Operator.  Over  & above,  major  incidents  are  also  investigated  by  OISD  /  committee  set-up  by  the  Ministry  of Petroleum and Natural Gas (MoP&NG) for the purpose. Root Cause Analysis (RCA) and lessons learnt from these investigation reports are shared with the oil companies for prevention of similar such incidents. ATR of the major process safety failures are monitored.

Based on major incident investigation, lapses, if any, the accountability are dealt by the Operators as per the provisions of CDA rules. Over & above, MoP&NG also regularly monitors the incidents across the Industry and takes suitable actions to avoid recurrence of such incidents.

(c). Approval  of  reinvestment  plans  is  an  ongoing  process  and  decision  to  approve  each reinvestment plan is taken depending upon its merit.

(d) & (e). Most of the fields of ONGC/OIL are old and matured, have crossed their plateau period of production and entered the natural decline phase (a natural process in the production life of oil fields).  To  maintain  /  augment  production  from  such  fields  is  very  challenging  and  requires additional development, use of new technologies and healthy reservoir practices. In mature fields, flowing  wells  becoming  non-flowing  and  revival  of  these  non-flowing  wells  is  a  continuous  and dynamic process which is an intrinsic characteristic of any oil/gas fields. ONGC/OIL over the years has developed in-house expertise to revive idle / closed wells. Wherever possible, efforts are made to revive the wells by using rig less techniques such as scrapping, hot oil circulation, nitrogen jobs, compressor application & other stimulation techniques like acid job, fracturing etc. However, where ever  needed  rig  is  deployed  to  service/revival  of  wells.  ONGC/OIL  is  redeveloping  its  matured fields  through  various  IOR  /  EOR  /  Re-development  schemes  and  application  of  appropriate technologies.

Companies  also  take  the  assistance  of  international  consultants  for  taking  up  complicated repair/trouble shooting jobs by applying the latest technology to revive idle / closed wells.

(f). Details  of  State-wise Exploration Expenditure of ONGC for the last three year and amount charged as bad debts during the corresponding period is given at Annexure-II & III respectively
