Characteristic of studies:

1 year postgraduate studies - „Drilling" give theoretical knowledge people working in Petroleum industry or looking for job. Program covers: Drilling, , Well Logging, Economics, Petroleum Geology, Oil Reservoir Production, Gas Reservoir Production, Well testing, Quality, Health, Safety & Environmental Management System and also more detailed classes like Rock Mechanics, Wellbore Design, Drilling  and  Production  Equipment, Drilling Fluids, Drilling Technology, Well Completion and Workover

Program:

Petroleum Geology - The petroleum system (comprising the hydrocarbon play concept).
Source rocks. Diagenesis of O.M. - kerogen and products of its transformation. Classification, composition of crude oils and gases. Classification of conventional reservoir rocks - clastics and carbonates. Non-conventional reservoir rocks. Sub-surface trapping  - role of the capillary pressure. Hydrocarbon accumulation - fields and pools. Sub-surface temperatures and pressures - HPHT. Natural hydrocarbon production mechanisms.
Geological sub-surface maps - structural and izopach. Methods of the estimation of oil and gas reserves.

Drilling - Vertical, directional and horizontal boreholes - construction and appropriately. Casing design and cementing of boreholes. Design of drilling pipes and bottom holes assembly. Drilling tools.

Rock Mechanics - Basic background, rock mass classification. Rock mechanical properties, strength, anisotropy. Water influence on rock properties. Stress in near borehole region. Borehole wall stability.

Well Logging - Environment of logging - borehole, flushed zone, invaded zone, virgin zone, wireline logging, MWD, LWD. Apparent parameters in logging, corrections. Variety of logging, physical parameters of rocks and physical fields - a basis of well logs. Resistivity logs - classic logs (Normal and Lateral), laterologs, Dual Laterolog: LLd and LLs. Micrologs - MSFL, electric imaging. Induction logs, Dual Induction, HRAI, simplified Doll's theory in induction logging. SP potentials: liquid-junction potential, redox potential, filtration potential. Anomalies on Resistivity curves and SP curve relating to lithology, porosity-permeability, shaliness of rocks. Effective porosity and water saturation from Archie's laws. Natural gamma radioactivity of rocks, geological reasons, measurements - standard and spectral, lithology and shaliness from GR.
