Role & application

At Shreem Petrochem, our team specializes in advanced subsurface modeling, a critical component of efficient oil and gas exploration. Subsurface modeling involves creating detailed 3D representations of underground geological formations, integrating seismic data, well logs, core samples, and petrophysical information. Our experts utilize industry-leading tools such as Petrel, Kingdom Suite, and GeoModeller to accurately map reservoirs, identify hydrocarbon traps, and evaluate potential production zones. Techniques like structural modeling, stratigraphic correlation, reservoir simulation, and geostatistical analysis allow us to predict fluid flow, porosity, and saturation with precision. By combining geological, geophysical, and engineering datasets, our models reduce exploration risks, optimize drilling locations, and enhance reservoir management strategies. This capability ensures Shreem Petrochem delivers actionable insights to upstream operators, enabling informed decision-making, cost efficiency, and higher recovery rates, positioning our team as a trusted partner in digitalized and data-driven oil and gas exploration.

Our Services

Petrel Inputs

Petrel requires a variety of inputs to build accurate subsurface models. Key inputs include seismic data (2D/3D surveys), well logs (gamma ray, resistivity, density, sonic), core data, and formation tops for stratigraphic interpretation. Reservoir properties such as porosity, permeability, fluid contacts, and pressure data enhance reservoir modeling. Geological maps, fault interpretations, and production history are also integrated. Combining these datasets enables Petrel to generate reliable structural, stratigraphic, and reservoir simulations for exploration and field development.

Seismic Survey

We process 2D and 3D seismic surveys to interpret structural features, faults, and stratigraphy. By combining seismic volumes with well logs, core data, and geological maps, our team creates high-resolution 3D models of reservoirs. This integration enhances reservoir characterization, identifies hydrocarbon traps, predicts fluid flow, and supports optimized drilling and production strategies, reducing exploration risks and improving recovery efficiency.

Petrophysical Info

At Shreem Petrochem, petrophysical information is essential for understanding reservoir properties in oil wells. Using well logs such as gamma ray, resistivity, density, and sonic data, we determine porosity, permeability, water saturation, and hydrocarbon volumes. Core sample analysis and formation evaluation complement this data, enabling accurate reservoir characterization. Integrating petrophysical information with seismic and geological models allows our team to optimize drilling, predict fluid behavior, and enhance hydrocarbon recovery efficiently.

Find HC traps & Zones

stratigraphic correlation is a key tool for subsurface understanding and reservoir mapping. By analyzing well logs, core data, and formation tops across multiple wells, we identify and correlate geological layers, depositional environments, and sedimentary sequences. This enables accurate interpretation of reservoir continuity, thickness, and heterogeneities. Integrated with seismic and petrophysical data, stratigraphic correlation supports optimized well placement, risk reduction, and improved hydrocarbon recovery in exploration and field development projects.
