Carbonate cement stratigraphy and timing of diagenesis in

Nov 01, 1995 A mixed carbonate-clastic sequence is one of several Miocene hydrocarbon-bearing reservoirs in the northwestern Sabah Basin. This sequence consists of bioclast-rich sandstones interpreted as prograding storm shoal deposits. The sequence contains a complex variety of carbonate nodules. The sequence has undergone nine stages of cementation that completely occluded pores.

Jul 21, 2020 Malaysia is divided into two parts Peninsular Malaysia and East Malaysia in the northern part of the island of Borneo. Peninsular Malaysia comprises 13 states, which account for ~85 per cent of the country's GDP. These states operate as one cement market that is distinct from the cement markets of the Sabah and Sarawak states in East Malaysia.

ABSTRACT: Carbonate Cementation and Dissolution in Miocene

The calcite has 87 86/Sr values of 0.70833 to 0.70865, eliminating coeval (~ 15 m.y.) seawater and marine carbonate (0.70873-0.70885) as a potential source. The 87 86/Sr composition of calcite cement is consistent with mass transfer of calcite from older marine sources to younger sediments. Fluid inclusion measurements indicate that ankerite

Spatial distribution of calcite cement in the Frewens sandstone was modeled using indicator geostatistics. Variograms were inferred from outcrop maps of cement. Indicator semivariograms of cement have a range of 30 m horizontally and 2.5 m vertically, dimensions that correspond approximately to the size of the largest concretions.

Abstract: Secondary Porosity in Sandstones of Lower Wilcox

The sands from the tidal-flat and bay-lagoon facies continued to compact as they filled more slowly with calcite cement. Initial lower porosity and permeability values in the tidal-flat and bay-lagoon sandstones, interpreted to be due mainly to higher matrix content, account for the retarded cementation rate.

Changes in microstructure characteristics of cement paste

Jul 01, 2018 2.2. Sample preparation. Cement paste samples were cast in cylindrical molds with 20 mm diameter and 100 mm height. A water to cement ratio of 0.35 was used to get proper consistency without bleeding as no water reducing admixture was used. 24 h after casting, the samples were demolded and then cured in lime saturated water for 120 days.

The Luconia Province—offshore Sarawak—is a key hydrocarbon province in Malaysia. However, the gas reservoirs in Central Luconia pose unique problems and challenges as they have partially water-filled microporosity that overprint wireline logs.
