... Abstract The paper will discuss the advancement of recent technology high definition resistivity imager convey with drilling assembly (Logging While Drilling) to quantify fracture geometry and secondary porosity (vuggs) in highly fractured carbonate. Oligo- Miocene carbonate Kujung formation...

... Abstract X Field is a carbonate platform setting in Central Luconia, Malaysia. The field faced declining trend of gas production due to early water rise. Seismic attribute shows that the rising water was assumed to be related to the water being drained through crossflow into the possible karst...

..., the Reservoir Mapping While Drilling tool was able to detect and map a hydrocarbon bearing sand ten metres below the original borehole. In Case Study-2, the DDEM tool was used to identify the current Gas Water Contact (GWC) in a carbonate field which was experiencing high water cut early in the life...

... Abstract Carbonate platforms in the Central Luconia is the most important province in the Sarawak Basin for gas production in the region. These carbonates are economically significant containing 65 trillion cubic feet of gas in place with minor contribution of oil rims. Over 200 carbonate...

... Abstract The intermediate phase on South Mahakam (SMK) field presented technical and economical challenges due to multiple bit runs, attributable to thick carbonates with Unconfined Compressive Strength (UCS) up to 30K psi. The typical phase is either 12-1/4" or 8-1/2", reaching 1600m long...

... carbonates in Papua New Guinea present significant challenges from the perspective of calculating hydrocarbons in place and assessing reservoir productivity. Given the heterogeneous nature of the carbonates, significant difficulties arise when attempting to determine productive intervals using only...

... Abstract Drilling exploration wells always carry increased risk given the lack of offset wells. Once of the main uncertainties usually is the depth prognosis derived from surface seismic depth converted data. The accurate prediction of the depth of top carbonate while drilling carbonate...

... of clay, silica, and carbonate, which act as source rock, and reservoir seals at the same time. They have very low permeability and often require massive stimulation to produce hydrocarbon. Generally, resource shale reservoirs must meet a series of requirements to make them economically viable...

... Abstract Intense compression in northeast Java and facies complexity in carbonates has triggered the complexity of petroleum trapping mechanism. Different fluid contact level between Ujung Pangkah and Sidayu field indicates something has happened during the migration. The shelf edge line...

... Abstract Successful production in shale gas plays largely depend on identifying hydraulically fracable zones. Considerable lithological and petrophysical heterogeneity is expressed by changes in clay, silt, carbonate, and organic content. These changes correspond to variation of the dynamic...

... Carbonate characterization is a well known complex and challenging subject aiming to describe the formation properties like porosity, permeability and saturation and delineating reservoir quality. It has been observed that porosity and mineralogy alone is incapable of defining the reservoir flow...

The model is fairly simple and consists of only 4 layers: two overburden layers, the Luconia carbonate, and one underburden layer. The rigid...

... is a carbonate where the framework-grain is composed almost entirely of Globigerina tests / shells with matrix of calcareous muds. According to its texture (Dunham's classification), the reservoir can be divided into grainstone, packstone and wackestone facieses. Grainstone is grain-supported and lacks any...

... acid distribution in carbonate formations can be achieved by increasing the viscosity of the acid in-situ. This can be done by using polymer/cross-linker or viscoelastic surfactant acid systems. The latter system was selected in the present study because of the tight nature of the reservoir...

... Abstract The ability of 4D seismic to image the fluid flow and locate bypassed oil in between wells especially in carbonate is a real challenge. The seismic observables that change with time as the extraction of hydrocarbon continues may not always be mappable since normally Gassman's equation...
