Geological inference of channel and polka-dot seismic anomalies in Yeongil bay, Pohang.

The Engineering Ocean Seismic 3D system, which enables ultra-high-resolution seismic surveys on a smaller survey scale, was deployed in Yeongil Bay, Pohang, South Korea. The region is renowned for abundant shallow gas deposits and faults. Based on acoustic impedance contrast and abnormal behavior observations, two seismic anomalies termed channel and polka-dot anomalies have been identified in the seismic volume.

Flow Characteristics of a Solid-Liquid Non-Newtonian Fluid for Directional Drilling.

As petroleum technology has developed, both slim-hold and directional drillings have developed as well. Although these techniques are currently being utilized in industry, the literature on them is still insufficient. In the present study, the friction coefficient, pressure loss, and particle transport ratio pertaining to these methods are measured.

Evaluation of the Structural Stability of a Heave Compensator for an Offshore Plant and the Optimization of Its Shape.

Offshore plant designs can be broadly categorized into hull-type designs and topside module-type designs. Compared to the hull-type design, it is much more difficult to design the topside moduletype design due to the complexity of its structure, making the design technology of professional engineering companies critical. A heave compensation system is a system that compensates the vertical shock imposed on a drilling ship by waves, and is installed at the top of the topside module.
