Drilling and Completion Services Cost Index Q2 2015
Drilling and Completion Services Cost Index Q2 2015 Prepared by Spears and Associates, Inc. 8908 S. Yale, Suite 440 Tulsa, OK 74137 www.spearsresearch.com July 2015 Drilling and Completion Services Cost Index: Q2 2015 Introduction The Drilling and Completion Services (DCS) Cost Index tracks and forecasts price changes for products and services used in drilling and completing new wells in the US. The DCS Cost Index is a tool for oil and gas companies, oilfield equipment and service firms, and financial institutions interested in benchmarking and forecasting well costs. Methodology Spears and Associates undertakes a quarterly survey of independent well engineering and wellsite supervision firms to collect “spot market” drilling and completion services price information for a specific set of commonly drilled wells in the US. The information in the “well profile” survey is collected in the form of detailed drilling and completion services cost estimates based on current unit prices and usage rates in each location at the end of the quarter. The well profiles are equally-weighted in calculating an average price change per quarter for the drilling and completion services cost components. A “total well cost” price change is calculated for each well profile covered by the survey which reflects the weighted average price change for each component of the well’s cost. An overall “total well cost” price change is calculated, with each well profile equally weighted, to determine the “composite well cost” index shown in this report. All cost items are indexed to 100 as of Q1 2008. “Spot” prices tracked by the DCS Cost Index are those in effect at the end of each quarter and as such may differ from prices averaged across the entire quarter. -

M. Soes, P. J. Spaans and P.Veenvliet With 2 figures Keywords: Romanogobio, Pisces, Waal, Rhine, The Netherlands, first record Schlagwörter: Romanogobio, Pisces, Waal, Rhein, Niederlande, Erstfund The whitefin gudgeon Romanogobia belingi (Lukasch, 1933) is recorded for he first time from The Netherlands 1 Introduction In the past years the fish fauna of the Dutch rivers belonging to the River Rhine system has been altered significantly. Species introduced to the Rhine system, such as Vimba (Vimba vimba), Asp (Aspius aspius) and Danube bream (Abramis sapa) are nowadays found in the Dutch waters (De Nie, 1996; Frey hof, et al., 2000; Van Emmerik, 2003). One Danubian species, the Tubenose goby (Proterorhinus marmoratus), invaded the River Rhine system via the Main-Danube-Canal and made it up to the Netherlands (Winter, 2002). Several other species of gobies are thought to follow (Freyhof, 2003). Already in 1998, Freyhof reported on another species in the River Rhine, which could be expected to occur in the Netherlands. This species, the White fin gudgeon (Romanogobio belingi (Lukasch, 1933), was found to be common and widespread in German parts of the River Rhine. -

Identification key for Austrian freshwater fishes This identification key should only be used for fishes from Austrian freshwaters. This key will possibly not work for fishes from other European countries. Nobody is perfect – schon gar nicht ein Bestimmungsschlüssel. Ein Bestimmungsschlüssel baut auf charakteristischen Merkmalen auf, er vereinfacht und kann keinen Anspruch auf Vollständigkeit erheben. Auch dieser Bestimmungsschlüssel ist nur ein Versuch ein komplexes System in einen übersichtliche Form zu bringen. Die Natur sieht aber oft anders aus. Die Bandbreite an Merkmalen ist bei vielen Arten groß. Manche Populationen sind an unterschiedliche Umweltbedingungen angepasst und bilden unterscheidbare ökologische Formen. Andere Populationen sind isoliert und einige davon sind systematisch noch ungenügend erforscht. Möglicherweise taucht ja in Österreich noch die eine oder andere neue Art auf. Sollte es einmal nicht passen, oder wenn sich ein Fehler eingeschlichen hat, ersuche ich um Information - [email protected] oder unter obiger Adresse.

Growth, the Length-Weight Relationship, and Reproduction in Vimba (Vimba Vimba L
Turk J Zool 2011; 35(1): 87-96 © TÜBİTAK Research Article doi:10.3906/zoo-0901-16 Growth, the length-weight relationship, and reproduction in vimba (Vimba vimba L. 1758) sampled from an oligo-mesotrophic lake in northwest Anatolia (Turkey) Hacer OKGERMAN1,*, Mahmut ELP2, Cumhur H. YARDIMCI1 1İstanbul University, Fisheries Faculty, Freshwater Biology Department, İstanbul - TURKEY 2Yüzüncü Yıl University, Agriculture Faculty, Van - TURKEY Received: 13.01.2009 Abstract: The growth parameters and reproduction period in vimba (Vimba vimba L. 1758) sampled from Sapanca Lake were determined monthly between September 2003 and July 2004. The 335 vimba specimens caught ranged in age from 2+ to 6+ years, and the majority of the samples consisted of individuals of the 4+-year-old age group. The length-weight relationship was estimated to be W = 0.0084 FL3.1797±0.0035 for males (r2 = 0.94, P < 0.05) and W = 0.0089 FL3.1572±0.0033 for females (r2 = 0.93, P < 0.05). Regression coefficients for sex were significant (t-test, P < 0.05). The slope (b) significantly differed (ANCOVA, P < 0.05) between months. The fact that the b values for male and female vimba specimens differed from 3.0 indicates that there was positive allometric growth. The von Bertalanffy equation was determined using Lt = 28.940 (1-exp {-0.123[t+2.193]}), ∅’: 2.030, (r = 0.999) for males and Lt = 24.708 [1-exp {-0.205[t+1.464]}), ∅’: 2.097, (r = 0.999) for females. The sex ratio was 1:1.86 (χ2; P < 0.05). The spawning period of vimba began at the end of April and continued until the beginning of July; the water temperature during this period was between 14.8 and 25.9 °C. -
Downhole Sensors in Drilling Operations
PROCEEDINGS, 44th Workshop on Geothermal Reservoir Engineering Stanford University, Stanford, California, February 11-13, 2019 SGP-TR-214 Downhole Sensors in Drilling Operations Nathan Pastorek, Katherine R. Young, and Alfred Eustes 15013 Denver West Blvd., Golden, CO 80401 [email protected] Keywords: MWD, LWD, Rate of Penetration, Drilling Data, Geothermal, Telemetry ABSTRACT Before downhole and surface equipment became mainstream, drillers had little way of knowing where they were or the conditions of the well. Eventually, breakthroughs in technology such as Measurement While Drilling (MWD) devices and the Electronic Drilling Recorder system allowed for more accurate and increased data collection. More modern initiatives that approach drilling as manufacturing— such as Lean Drilling, Drilling the Limit, and revitalized Drilling the Limit programs—have allowed petroleum drilling operations to become more efficient in the design and creation of a well, increasing rates of penetration by more than 50%. Unfortunately, temperature and cost limitations of these tools have prevented geothermal operations from using this state-of-the-art equipment in most wells. Today, petroleum drilling operations can collect surface measurements on key drilling data such as rotary torque, hook load (for surface weight on bit), rotary speed, block height (for rate of penetration), mud pressure, pit volume, and pump strokes (for flowrates). They also can collect downhole measurements of azimuth, inclination, temperature, pressure, revolutions per minute, downhole torque on bit, downhole weight on bit, downhole vibration, and bending moment using an MWD device (although not necessarily in real time). These data can be used to calculate and minimize mechanical specific energy, which is the energy input required to remove a unit volume of rock. -

Boreal Env. Res. 23: 339–353. To study the effects of a dispersal barrier on migration of the semi-anadromous vimba bream in the Pärnu River, Estonia, we tagged thirty fish with acoustic transmitters and released above the barrier. Tagged fish showed variation in behaviour, and 16 different spawning movement patterns were identified. Several fish moved > 25 km upstream. Batch spawning was suggested by stops in up to four different spawning areas. The fish descended to the sea after spawning in spring; females earlier than males. After spending on average 137 days in the sea, they returned to the river during autumn and stayed in the river on average 174 days until the next spawning. The fish were most active during sunrise and sunset. In conclusion, the study shows that the dam prevents a diversification of migra- tion behaviour and the associated expansion of spawning areas.
