Technical Directorate

Location of Work : Yuzhno-Sakhalinsk

Work Pattern : 5/2 office

Accountabilities

The Employee performs the following responsibilities:

Build, maintain and improve hydrodynamic models using the Dynamo dynamic modelling tool suite (Reduce+

+, MoReS, HFPT/PTNet), updating to account for production history, surveillance and new well data (including

integrating all seismic, geological and petrophysical data as well as facilities processing capacities and

constraints), and to incorporate revised geological models and new 3D or 4D seismic information.

Follow the IRM (Integrated Reservoir Modelling) process in the preparation, integration, and assurance of

hydrodynamic models, and related production forecasts, and recoverable volume estimates.

Gather and analyze reservoir engineering data required for generation of hydrodynamic reservoir models.
Define and deliver reservoir simulation models as input to reservoir management and field development

optimization.

Perform history matching and support field development planning and production forecasting using dynamic

simulation models. Assist in the preparation of medium-term production forecasts for each well. Provide support

to the generation of long-term production forecasts to the Company business planning.

Provide reservoir engineering technical expertise and operational support for preparation of Reservoir

Management Plans.

Perform analytical analysis such as material balance calculations to support production forecasting and

estimates of recoverable hydrocarbon volumes.

Analyze historical field performance using decline curve analysis to support production forecasting and

estimates of recoverable hydrocarbon volumes.

Provide reservoir engineering technical expertise and operational support for well maturation activities.
Incorporate subsurface uncertainties into hydrodynamic modelling workflows in order to assess impact to

production forecasts and recoverable volume estimates.

Conduct probabilistic workflows to quantify the range of possible production outcomes. Derive deterministic

model realizations aligned with percentiles of interest (e.g. P10, P50, P90 models).

Contribute to the annual Company ARPR (Annual Review of Petroleum Resources) through the delivery of

hydrodynamic simulation models and recoverable volume estimations.

Provide input to proposals for interventions to increase oil production such as workovers, rigless interventions,

acid jobs and hydraulic fracture treatments.

Perform fluid characterizations of hydrocarbon fluid samples to derive PVT models suitable for dynamic

simulation.

Analyze data from laboratory Special Core Analysis to derive relative permeability models suitable for dynamic

simulation.

Provide input to proposals for rigless well interventions to obtain data such as PLT surveys, MDT surveys and

down-hole PVT sampling.

Contribute to After Action Reviews and End of Well Reports etc.
Provide advice on compliance and reporting with regulatory requirements as stipulated by the Russian

Federation (Accounting Chamber, MPR, RTN and RPN audits, CRI reports, AGR/BRR/AMP/AIR).

Produce reports suitable to document work done in the generation of hydrodynamic models and the resulting

analysis, history matching and production forecasting.

Performs other tasks received from Line Manager and performs all other responsibilities required for fulfilment

of the tasks and functions assigned to the Org.Unit.
