“…Understanding what has been stated by Chilingarian et al in 1992, it can be stated that all geological events during the deposition process and diagenetic played a role in the establishment of the physical character of the rock. Each depositional environment and diagenetic forming rocks with special geological features that characterize the physical.…”

“…In fact, rock typing carbonate rocks parameter by integrating geology and petroleum engineering is not easy. Research conducted by Rushing et al (2008) stated that the reservoir rock typing in tight heterogeneous (Chilingarian et al, 1992) and its potential as a hydrocarbon reservoir is very large. More than 60% of oil reserves and 40% of world gas reserves are in carbonate reservoir rocks (Akbar et al, 2001).…”

Carbonate rocks are highly heterogeneous. That which leads to rock typing of carbonate rocks is noteasy to do even by integrating static and dynamic properties of rocks. In accordance with the defi nition ofrock types that are commonly used, rocks or parts of rocks that have been deposited in the same environmentand experienced similar diagenetic process have similar physical characteristics, such as grain orrock fabric texture, pore geometry and structure pores, then the characters that will be used as the basisfor determining rock types. The use of rock fabric has been performed by many previous researchers. Whilethe use of attributes in the rock pores typing is still limited and more emphasis on engineering purposes.The objective of this study is to integrate all three of these characteristics in the determination ofrock typing. Theories that have been established and related to fl uid fl ow in capillaries and porousmedia that will be used to characterize the pore geometry and pore structure. Furthermore, thecharacteristics of the geological evidence will be conducted using core description, petrographyand other data to obtain the relationship between aspects engineering and aspects geology inaccordance with concept or defi nition of rock type in question. In rock typing, permeability and porosity characterize the pore geometry and pore structure. This study proves that there is a strongrelationship between the characteristics of the detail geological and architecture pores. Thus,the resulting methodologies rock typing can be universal with respect to aspects of geology andpetroleum engineering.

“…The purest limestone can be seen in Sadi solid with the Ca/Mg ratio of 148.30 that can be called calcitic limestone. These classifications were made according to the proposed Ca/Mg ratio [12]. A notable amount of calcium (Ca) element was found in all samples, represents calcite [CaCO3], dolomite [CaMg(CO3)2] and ankerite [Ca(Fe,Mg,Mn)(CO3)2], which are the major compounds in carbonate rocks.…”

This manuscript aimed to propose a new approach in estimating the cutting transport ratio through a relationship between equivalent circulating density (ECD) and drilled solid concentration from different formations in a nearly vertical well. A laboratory test utilising drilled cuttings from North Kuwait Field was conducted to simulate drilled solids-laden mud for accomplishing this purpose. The drilled solids were taken from four formations, namely Radhuma, Tayarat, Hartha and Sadi. The rheological behaviour of the drilled solids-laden mud was conducted according to API Recommended Practice 13B. In addition to laboratory tests, a database was established from drilled solids produced in the three wells of the North Kuwait field. As a result of the laboratory tests and actual field data, new empirical equation between drilled solid concentration and equivalent circulating density was proposed. ECD from laboratory works matched with the ECD field at an R2 value of 0.93, proving the data’s reliability. This empirical equation can be used to calculate the cutting transport ratio and later can be used to optimise drilling operations.

Shock-Induced Borehole Waves and Fracture Effects

We perform wave experiments using a vertical shock tube setup. Shock waves are generated by the rupture of a thin membrane. In the test section, the incident pressure waves generate borehole-guided waves along water-saturated samples. The tube is equipped with side wall gages and a mobile pressure probe, so that the attenuation and reflection of the wave can be measured. The computation for a single horizontal fracture intersecting a vertical borehole gives a quantitative prediction of reflection and transmission of borehole-guided waves. Three different fracture apertures are used for the calculation. Fracture aperture significantly affects both reflection and transmission coefficients. Large fractures increase reflectivity and decrease transmissivity. In the experiment, we found that both pressures above and below the fracture are influenced by the fracture aperture indeed, thus indicating the potential for fracture detection by borehole waves.
