Logistic Handling of Deliveries at an LNG Terminal
LNG is a gas mixture of hydrocarbons in the following proportions: methane 87–99 mol%, ethane 0.1–5.5 mol%, propane 0–4 mol%, butane 0–2.5 mol%, nitrogen 0.02–1 mol%, and traces of sulfur (less than four ppmv) and CO2 (50 ppmv). There has been growing interest in fuel supply chains regarding transport safety and LNG reloading. This is due to the increasing consumption of this gas in the economy to create sustainable transport systems. Poland is in the phase of energy transformation, which increases the demand for this type of alternative fuel. For this reason, the number of logistic operations carried out by Polish sea terminals handling LNG deliveries is increasing.

Influence of Axial Compressive Stress on Pipeline Network
Due to their exceptional structural integrity, steel pipelines are the main component for oil and gas transmission. However, these pipelines are often affected by corrosion, despite corrosion protection, because of harsh working conditions. In addition to corrosion defects, pipelines are often subjected to multiple external loads. The combination of corrosion defects and external loads can significantly reduce the failure pressure, resulting in various failure behaviors. This reduction in failure pressure is especially critical in pipe bends as they are the weakest link in a pipeline.

Industry Guidance on Pipeline Integrity Management
For operators of oil and gas to save the cost of unforeseen events and risks, and to avoid unnecessary shutdowns, there is a need to have an effective subsea pipeline integrity management system. Currently a large number of subsea pipelines around the globe have already exceeded their design lives; nevertheless, they are still being operated safely, effectively and with diligent consideration towards Environmental, Health and Safety regulations, as well as international standards and best practices. In addition, many older flowlines have no permanent pigging facilities due to various design and operational limitations. For the unpiggable pipeline, the vast majority of the oil and gas operators use different inspection and monitoring techniques to provide essential integrity management data such as product chemistry, cathodic protection, electrical resistance probes and coupons, etc. However, translating such essential integrity management data into meaningful information to make crucial integrity-based decisions can be challenging.

Guideline for the Decommissioning/Abandonment of Subsea Pipelines
The operating lifespan of pipelines is limited, defined by their specific design codes and specifications, with the economic justification for this being determined primarily by the pipeline owner. During its operational lifespan, a pipeline’s integrity is affected mainly by the quality of the hydrocarbons being transported. The integrity of a pipeline can be maintained with regular inspections and maintenance/cleaning programmes followed from installation to commissioning. As production matures and declines, operators face several decisions concerning the pipeline’s future. There are several potential scenarios, and each should be assessed on a case-by-case basis for any specific pipeline in question. The industry best practices outline the minimum requirements for the safe decommissioning of pipelines.

Gels for Conformance Control and Flow Diversion
The use of hydrogels in the development of oil fields by the flooding method has firmly established itself in the oil industry, and this direction is constantly evolving in all oil-producing countries around the world, as evidenced by the growth of publication and patent activity on this topic. Operations for conformance control and flow diversion are impossible to imagine without the use of gel technologies today. Inorganic, organic, and hybrid gels, as well as foam gels, gel-forming and gel-dispersed systems are used. The ability to widely regulate structural-mechanical properties, thermal stability, and shear resistance through the introduction of micro- and nano-sized additives has made hydrogels indispensable tools for petroleum engineers.

Fracture Conductivity Damage on Post Hydrofrac Well Productivity
Hydraulic fracturing or hydro-frac fluids can impede well production due to the damage caused to the reservoir formation and fracture face, generated from adverse interactions with reservoir rock. Understanding the mechanisms of hydraulic fracturing, optimum treatment designs, and pumping/pressure profiles is critical for hydro-frac success.

Fracture Characterization of Naturally Fractured Reservoirs
Recent developments in fracture characterization, modeling, and the impact of fracture networks on oil recovery in naturally carbonate-fractured reservoirs have been reviewed. The pivotal role of fracture identification and characterization in understanding production mechanisms and developing realistic fracture modeling approaches has been highlighted. This concludes that improved fracture network modeling requires considering various factors, such as data collection, fracture characterization, reservoir simulation, and model updating based on newly acquired field data. Integrating multiple techniques and data sources is recommended for obtaining a reliable reservoir model to optimize primary and enhanced oil recovery methods.

Forward and Reverse Combustion
In situ combustion or fire flooding is a promising enhanced oil recovery (EOR) technique designed to produce heavy oils and bitumen. This method involves the in-place heating and combustion of hydrocarbons, resulting in reduced viscosity and increased mobility for improved flow toward the production wellbore. Despite its potential, widespread commercial implementation of in situ combustion has been hindered due to technical and economic challenges like inadequate project design and improper reservoir selection.
