OPERATIONS

Twenty-six fields and more than 1,200 wells to take care of and enhance!

Our current main operations are based in the west and south-west of Romania. We operate for OMV (through Production Enhancement Services Contracts (PEC) of 15 years. New operations are about to be started and will be added in due time.

Investments

As an example in these operations, we have invested more than 100 mils. USD in the last five years, in:

  • G&G studies and reservoir modelling;
  • More than 300 workovers (perforations, re-completion, hydraulic fracturing, water shut off, gravel packs…) and new wells;
  • Artificial lift optimization;
  • Surface facilities modernization, automation and real time monitoring;
  • Stranded Gas Solutions: Gas To Power.

  • Opex/boe has been reduced by 50%.
  • GHG intensity has been reduced by 60%.
  • Reduced Energy intensity by 3.
  • Reduced Freshwater withdrawal intensity by 60%.
  • Surface facilities footprint reduced by half.

Case Study 1.

The PEC, situated in the west of Romania, is an operation producing oil and gas from 123 wells and 16 gas wells, with technical details as follows.

Producing from three geological units:

  • Pannonian
  • Miocene
  • Basement

The oldest production record dates in 1967. In total, 893 wells have been drilled. Currently, the fields are producing from 123 oil wells and 16 gas wells. With an additional eight water injection wells and nine water disposal wells.

The fields record today an average daily production of around 1,500 bbls of oil and condensate/day and 120 kscm of gas/day . This is around 160% above the baseline after 5 years of investment and operatorship.

What are the main issues we identified and how did we manage to overcome them?

Most issues identified were related to operations, including but not limited to:

  • Corrosion of downhole and surface equipment;
  • Sand production;
  • Large amount of water produced to be disposed;
  • Low water injection rate, at high pressure;
  • High Skin and formation damage.

How did we deal with such issues?

We divide our planned works into short-mid and mid-long term goals.

In terms of short-mid term works, we conduct the following operations:

  • Production and pressure monitoring for keeping hydrocarbon production and wells  in function;
  • Well by well peer-review done quarterly;
  • Reservoir studies done in house by integrating all the available data into a coherent model.

In the mid-long term, we make:

  • WO programs, implemented gradually, in order to cover as many wells with dysfunctionalities as possible, every year
  • infill drilling analysis
  • water injection – monitoring and development
  • various stimulations

Case Study 2.

The Țicleni PEC, situated in the south-west of Romania, is an operation that produces oil and gas from 200 wells, with technical details as follows.

Producing from four formations, including:

  • Burdigalian (Helvetian)
  • Sarmatian
  • Meotian
  • Oligocene(Targu Jiu area)

It is producing from 1953 to the present day.

Out of a total of 1,282 wells drilled since the fields started producing, currently, there are 200 active wells in the seven fields, with a total production of around 2,500 bbls of oil/day and 250 kscm of gas/day. This is more than 50% above baseline after 2 years of investment and operatorship.

What are the main issues we identified in and how did we manage to overcome them?

As the fields have been producing for more than 50 years,  problems specific to mature fields were encountered, both related to geological data and operations.

In terms of data, the main issue encountered was having an incomplete geological database to work with, the available data having insufficient detail level to explain the geological issues. In the same time, assumptions of the geological model were not always clear.

As for the operational side, we encountered several issues, including but not limited to:

  • poor reservoir flowing properties, with stimulation jobs required;
  • production back-allocation;
  • poor or unconsolidated formations;
  • formation damage during drilling;
  • high heterogeneity of reservoirs;
  • quality of well construction.

How did we deal with such issues?

We divide our planned works into short-mid and mid-long term goals.

In terms of short-mid term works, we conduct the following operations:

  • production and pressure monitoring for keeping hydrocarbon production and wells  in function
  • well by well peer-review done quarterly
  • reservoir studies that were done in house by integrating all the available data into a coherent model

In the mid-long term, we make:

  • WO programs, gradually, to cover as many wells with dysfunctionalities as possible every year
  • drilling new wells as found necessary
  • water injection
  • restarting production in wells that have potential
  • Infill drilling analysis
