The performance efficiency in drilling oil, gas wells is eventually measured by means of comparing the time versus depth curve. However this is now being questioned, is a well drilled relatively in a shorter time period the most efficient well? Large data are now being acquired while drilling, however not all of the data available is utilized appropriately to get the big picture of the well being drilled. This research study is aiming to introduce a performance comparison methodology based on Rate of Penetration (ROP). All other operational steps other than drilling activity is routine unless there are hole problems and not dependent on formation. Drilling ROP on the other hand is a parameter that can be used to benchmark the efficiency of the drilling performances. In this research study the data of 40 wells drilled in Middle East Geomarket is used. This document describes ROP Indexing Methodology for drilling performance, and gives examples of its application from actual data. The study showed that previously used drillability performance comparisons by the industry are not feasible for benchmarking. It is obvious that he drilling industry needs a new methodology to benchmark drilling performance of the wells using advanced computers and available data being acquired from the rigs.

A new fully probabilistic methodology and a software for assessing uncertainties and managing risks in shale gas projects at any maturity stage Tugan, Murat Fatih; Sınayuç, Çağlar (Elsevier BV, 2018-09-01) Shale oil and shale gas projects generally have marginal economics, hence should be carefully analyzed from the economic standpoint. Generating an economically recoverable resource (ERR) probability function that shows the full uncertainty range is highly important for such an economic analysis. Furthermore, the net present value (NPV) of the project together with the uncertainties inherent in it should be revealed so that the primary decision of entering a shale oil or shale gas project will be determined....
Estimation of permeability and rock mechanical properties of limestone reservoir rocks under stress conditions by strain gauge Iscan, A. G.; Kök, Mustafa Verşan; Bagci, A. S. (Elsevier BV, 2006-08-01) Petroleum engineering reservoir parameter calculations are generally performed in the absence of the overburden pressure effect. This leads to serious errors in further development of a hydrocarbon-bearing reservoir. Thus, measurements under stress conditions become important vitally. The objective is to correlate the overburden pressure and the permeability to see the overburden pressure effects on the permeability of Turkish southeastern limestone reservoir rock samples. Stress was applied to four represe...
Heavy-oil solution gas drive: a laboratory study Akın, Serhat (Elsevier BV, 2002-07-01) When some heavy-oil reservoirs are produced using solution gas drive, they show: (1) higher than expected production rates, (2) low produced gas-oil ratio, and (3) relatively high recovery. The reasons for this behavior are not clear. A series of X-ray computerized-tomography (CT)-monitored, heavy-oil pressure depletion experiments were carried out to examine the core-scale phenomena using high pressure/high temperature equipment. Viscous white mineral oil (mu = 220 cp at 20 degreesC) and 9degrees API heavy...
Revisiting Current Techniques for Analyzing Reservoir Performance: A New Approach for Horizontal-Well Pseudosteady-State Productivity Index Al-Rbeawi, Salam (Society of Petroleum Engineers (SPE), 2019-02-01) The objective of this paper is to revisit currently used techniques for analyzing reservoir performance and characterizing the horizontal-well productivity index (PI) in finite-acting oil and gas reservoirs. This paper introduces a new practical and integrated approach for determining the starting time of pseudosteady-state flow and constant-behavior PI. The new approach focuses on the fact that the derivative of PI vanishes to zero when pseudosteady-state flow is developed. At this point, the derivative of...
Thermal characterization of crude oils by pressurized differential scanning calorimeter (PDSC) Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2019-06-01) In this research, pressurized differential scanning calorimeter (PDSC) were used to estimate the thermal and kinetic behaviour of two different crude oils from Tatarstan oil fields under three different pressures (100, 600, 2000 kPa) at a constant heating rate (10 degrees C/min). The heat flow curves of both crude oils indicated two reaction regions known as low temperature oxidation (LTO) and high temperature oxidation (HTO). The reaction intervals were shifted to lower temperature regions with the increas...
