| Abstract: | An investigation of the geotechnical properties of sediments from 57 boreholes drilled in West Delta and South Pass OSC Lease Areas, offshore Louisiana, indicated that sediment texture, shear strength, water content, and liquid limit vary significantly laterally and with depth. Samples are predominantly soft, fine‐grained sediments with high water content and medium to high plasticity. Firm, coarser‐grained sediments were obtained near the shoreline in South Pass OCS Lease Area and in the northern and eastern parts of West Delta OCS Lease Area. Trends in the distribution of geotechnical properties appear to be influenced by sediment texture and rate of sedimentation. |
