Knowledge of the in‐situ sound velocity of drilling mud can be used in mud‐pulse acoustic telemetry for evaluating the presence and amount of gas invasion in the drilling mud. We propose a model for calculating the in‐situ density and... more
A predrill estimate of pore pressure can be obtained from seismic velocities using a velocity-to–pore-pressure transform, but the seismic velocities need to be derived using methods having sufficient resolution for well planning purposes.... more
Correctly landing and drilling highly deviated wells in thin reservoirs can be challenging. In recent years, development of the Belida Field in the West Natuna Basins has focused on the Gamma 1B which is a thin (8-10 ft.) sand within the... more
Origin of Permeability in Carbonate Rocks Carbonate reservoirs, which are typically dual or triple porosity systems, produce a major portion of the world’s oil and gas and hold more than half of the world’s largest crude oil and natural... more
In an effort to understand the present-day thermal structure of the Jeanne d'Arc Basin, we derive matrix thermal conductivity values, using a geometric mean model, from thermal conductivity values of thirteen lithologic end-members (of... more
This article presents the results of a research study based on two language teaching techniques, drilling and color-coding, and their effect on the correct pronunciation of the past tense phonemes /t/, /d/, and /ɪd/ in regular verbs in... more
Polimer matrisli kompozit (PMK) malzemeler sahip oldukları mühendislik özelliklerinden dolayı havacılık ve uzay sanayisinin yanında günlük yaşamda da oldukça sık kullanım alanına sahiptir. Ancak karmaşık yapıya sahip olmaları sebebiyle... more
Since the advanced technology used in oilwell drilling is difficult and costly, the drilling must be completed in the most appropriate conditions, in the shortest time, with cost-effective and the targeted depths and purposes. This... more
During the drilling process, we need to look at several aspects that need to be considered, including the drilling mud aspect which is one of the important aspects in a safe and efficient drilling process.The success of a drilling process... more
Many breakwaters and jetties have become permeable to sand transport and wave transmission, a condition that results in increased operations and maintenance dredging costs and increased risks and delays to navigation. First-cost savings... more
Mineral oils, chemically synthesized emulsifiers, and additives are the basic ingredients of commercially available metal working fluids. Its application in metal cutting have earned widespread acceptance all over the world. However,... more
High-frequency torsional vibration percussive drilling is considered a promising approach to improve drilling performance in deep hard formations, so studying its rock breaking mechanism and effect is the essential and basic issue.... more

This project investigates characteristics of vibration of a drillstring under the action of weight on bit and drillstring rotation. The dominant cause of drillstring and bottom hole assembly's failures, shocks and severe damages to... more
Salt formations are encountered in many oil-producing regions of the world. These salt zones can be in a variety of forms; salt domes, massive beds and sheets or lenses. The chemistry of salts can very significantly even in a single bed,... more
For years researchers have been trying to discover the magic formula for teaching foreign languages. Several approaches have been tested since the 1950’s, from the audiolingual approach, which was basically teacher-centered and focused on... more
