Published: March 2018

This study investigated the trace element
potential of stratigraphic units in Kulakçayırı Lake and its vicinity, in
Arnavutköy. In this context, trace element analysis was carried out using three
drilling samples taken from Kulakçayırı Lake. In addition, grain size
distribution analyses were performed to determine the lithological properties
of the drilling samples in the stratigraphic sequence. At the base of the lake
bed, there is a distribution of sediment consisting of clay from 3 to 6.5 m
thick, and at deeper levels, clayey sand, or sandy clay.

In the analyses, nineteen separate
elements and CaO, TiO2 and Fe2O3 concentrations were determined using X-ray
spectrometry methods. Wavelength Dispersive X-Ray Fluorescence Spectrometry
(WDXRF) was used for these measurements.

As a result of the elemental analysis,
heavy metals including cobalt (Co), nickel (Ni), copper (Cu), lead (Pb),
chromium (Cr), and radioactive elements including uranium (U) and thorium (Th),
were detected in the sediments. In addition, rare metals (lanthanum, cerium and
neodymium) of the lanthanide group were also found. In particular, the
elevation of the Pb concentration in the BH-1 drilling location is remarkable.
This height is due to the sediment structure around the natural lake.

Digital skills are needed in order to use digital media for learning purposes and to cope with today’s knowledge society. In recent years, digital storytelling has become a modern way of telling stories, and in learning facilities it has been used as a reflection medium. Vocational training often requires the dissemination of tacit and practice-based knowledge, and the trainers of vocational teachers have been lacking an appropriate approach. The aim of the study was therefore to evaluate digital story-telling as an educational approach in vocational education. Data were obtained by participatory observation and included 19 digital storytellings, text analysis of 18 subject evaluations and text analysis of 19 reflection notes. Data from visual material (digital storytelling) and textual analyses were categorized, grouped and then discussed and analyzed using phenomenological analysis.
Our findings showed that digital storytelling as an educational approach, promote learning outcomes through practical skills and increase the active use of subject terminology. The results showed further that digital storytelling promote reflection on one own and others’ actions and thus increase understanding of the actual work process in vocational education.
Digital stories as an educational approach can increase didactic skills and hence digital skills while allowing participants to learn from each other’s challenges.

Published: March 2018

Objective: This study aims to compare maternal and fetal responses during two physical exercise types.
Design: A randomized clinical trial compared 120 pregnant women, gestational age of 35-37 weeks, 56 exercising on a stationary bicycle (Group A) and 64 on a treadmill (Group B).
Methods: Participants were monitored for three 20-minute phases: resting, exercise and recovery. Fetal heart rate (FHR) and maternal heart rate (MHR) were monitored. Glucose and lactate levels were evaluated at rest and during exercise.
Results: After the beginning of exercise, maximum lactate (L) levels were reached at 20 minutes and never exceeded 4 mmol/l. FHR decreased by 22 bpm during exercise in relation to resting values, irrespective of the exercise type (p<0.001). Comparing the exercise types, the incidence of bradycardia after 10’ was 23.2% in Group A and 35.9% in Group B (p>0.05), increasing at 20’ to 32% and 40.6%, respectively, (p>0.05). The FHR decrease during exercise was accompanied by a simultaneous increase in its variability (p<0.001), nevertheless a rapid return to resting values was observed shortly after exercise end. Glucose decreased in both groups irrespective of the exercise type (85 mg/dl at rest; 79 mg/dl during exercise and 81 mg/dl during recovery; p<0.001). There were no hypoglycemia cases.
Conclusions: FHR variability increase and the rapid return to resting values after exercise suggests that the FHR fall and the presence of bradycardia during exercise is the fetal physiologic response to blood flow redistribution, with maintenance of fetal well-being.
Key-words: Exercise; fetal heart rate; glucose; maternal heart rate; pregnancy

Tectonic Evolution and Hydrocarbon Prospectivity of East Coast Basin, Offshore Hawke Bay, New Zealand
Authors: Erdi Aurio , Huuse Mads , Bachtiar Andang 
Published: March 2018

Abstract
East Coast Basin (ECB) is situated on an active convergent margin that has been influenced by a long subduction history between the Pacific and Australian plates. Exploration activity in the onshore region of this area is shown by 40 wells with over 300 hydrocarbon seeps indicating the presence of an active hydrocarbon system. On the other hand, the offshore area has only three wells, all of which encountered significant gas shows. Regarding the offshore area, one of the problems is less understanding of migration pathway leading to uncertainty in prospect identification.
This study tries to approach this issue by identifying the relationship between regional tectonic framework, pathways for fluid to flow and hydrocarbon potential in the offshore ECB particularly in the thrust triangle zone within this area. While 2D and 3D seismic analysis has identified the tectonic features, palinspastic reconstruction, complemented with recent knowledge of regional tectonics, was performed to represent reasonable solutions for the tectonic evolution of offshore ECB. On the other hand, seismic observations complimented by seismic attribute analysis identify fluid related features related to faults in the offshore area.
Analysis of the datasets indicate four main tectonic events in the offshore area consisting of (1) Pre-Miocene deposition in passive margin settings, (2) Early-Middle Miocene deposition while thrust faults formed in the compressional phase, (3) Late Miocene deposition while listric faults formed in the extensional phase and (4) Pliocene-Holocene deposition with structural inversion in the compressional phase until recent. On the other hand, observations of chimneys associated with listric faulting indicates the Late Miocene extensional phase created migration pathway for fluid to flow from Cretaceous-Paleogene source rock. An assessment of trapping configuration, as well as a presence of high amplitude anomaly bounded by reactivated fault in the study area, offers a promising late Miocene prospect in the offshore ECB. Understanding the tectonic evolution, fluid related features and hydrocarbon potential within the offshore ECB provides insight into the petroleum system as well as potential prospectivity identification in this area.
Velocity Estimation by Joint Migration Inversion: An Example from a Field in the Malay Basin
Authors: Arshad Abdul Rahim Md , Ghosh Deva Prasad , Latiff Abdul Halim Abdul 
Published: March 2018

Abstract
Standard seismic processing method of estimating velocity is to remove multiples. In this paper, we utilized multiples that contain valuable subsurface information. A line from a field in the Malay Basin were used to estimate an interval velocity using the Joint Migration Inversion (JMI) method. The motivation for this approach are 1) multiples increase illumination especially in the shallow shadow zones, 2) multiples provide an additional sensitity to velocity errors and 3) the velocity estimation process is automated. In the JMI method, seismic imaging is done in a closed-loop manner as opposed to the standard seismic processing open-loop method. The initial migrated seismic image is feedback to a forward modelling algorithm. This allows an iterative minimization of the difference between the simulated and the real measurements. This also enable velocity estimation to be carried-out simultaneously. The method was first applied on a synthetic data before an application to a real data set from the Malay Basin. The results obtained showed that multiples can be utilized to get an accurate velocity model while at the same time getting a better seismic image of the subsurface.
Wheatstone Subsea Installation - Challenges Associated with Large Numbers of Subsea Heavy Lifts and Spools Offshore Australia
Authors: Cosson Damian , Rowe Michael , Koolhof William 
Published: March 2018

Abstract
This paper describes the installation scope for the Chevron-operated Wheatstone Project, including the following items: A number of heavy subsea structures comprised of Pipeline Termination Structures, Subsea Isolation Valves (SSIV) and drill centre manifolds.Fabrication, metrology and installation of a large number of clad tie-in spools of widely varying weight, length, shape and stiffness.Tie-in spools at the Wheatstone Platform (WP) to connect the WP risers to the SSIVs and flowlines (and associated diver-assisted flanged connections).
A Dynamically Positioned Heavy Lift Vessel (DPHLV) was used for the subsea structures installation campaign. The DPHLV performed 13 heavy structure lifts in a range of water depths. The maximum structure weight was 527 tonnes (Te).
A Heavy Construction Vessel (HCV) was mobilised to perform the deployment of 68 spoolpieces, ranging in size from 4" to 44" internal diameter. A range of spool spreader-beam arrangements was incorporated depending on the spool geometry and weight. The maximum combined spool plus spreader weight was 188Te.
The subsea structures were installed within very tight seabed landout tolerances. Such tolerances were achieved using the vessel's Class 2 Dynamic Positioning capability, as well as the calibration of an acoustic seabed survey array which provided the necessary global subsea positioning reference.
The spools offshore lifting operation, including multi vessel-interactions, was a technically challenging and weather sensitive activity. Safe and efficient methods were developed for the transfer of personnel from HCV to barge, mooring the barges to the HCV, and tagging the spools during lift off barge. The HCV was also used to tie-in the spools at the drill centres using diverless connection systems.
The spools deployed in the vicinity of the Wheatstone Platform were tied-in using a Dive Support Vessel. Pipe handling frames and air bags were operated by the divers to assist flange tie-ins of the stiff and large diameter spools.
The structures were installed in seastates up to 1.8m Significant Wave Height, with the governing case for the installations being seabed landout. A high capacity Passive Heave Compensator (PHC) was incorporated into the rigging arrangement to dampen the load during seabed landout, hence allowing landout within the maximum allowable speed. The PHC also ensured that vessel roll was kept to a minimum by allowing for a controlled unloading of the crane, and that there was no structure re-impact with seabed during de-ballasting operations upon seabed landout.
Least-Squares Reverse Time Migration Using Generalised Diffraction-Stack Imaging Condition

Published: March 2018

Abstract
Reverse time migration (RTM) is a wavefield-continuation method which is accepted as the best migration method currently available for imaging complicated geology. RTM is defined as a reversal procedure of seismic wave propagation, but, conventional RTM does not formulate this reversal procedure as an inverse problem. This problem can be solved using least-squares migration (LSM). This paper presents developing RTM by utilizing least squares inversion process. A matrix-based least squares RTM (LSRTM) algorithm is studied by employing the generalized diffraction-stack migration method. A simple layered model with an anticline structure, and Marmousi model are used to monitor how LSRTM can improve the imaging of dip reflectors, steep dips and the pinch-out. The LSRTM method succeeded to image the flanks, remove noises and improve the resolution. Inversion process of least squares RTM was more efficient than conventional RTM to enhance the resolution of image, remove the artifacts, and correct the amplitude.
Experimental Research on Lateral Vibration of Drill String in the Highly Deviated Well

Published: March 2018

Abstract
Drilling is one of the most costly and risky activities in oil and gas reservoir exploration and field development. A portion of this high cost is related to unwanted vibrations of the drill string. Assumed as the primary cause of many problems, drill string vibration is an ongoing challenge for drillers. In this paper, the lateral vibration characteristics of drill string in the highly deviated well are quantitatively analyzed and the influence of different drilling parameters on lateral vibration are fully evaluated.
In order to study the lateral vibration characteristics of drill string in the highly deviated wells under different drilling parameters, a drill string dynamics simulation apparatus was built according to the similarity theory, and the vibration response in different directions was measured. The lateral vibration frequency of drill string was calculated by Fast Fourier Transform (FFT) and the non-dimensional frequency was defined to quantitatively evaluate the relationship between the vibration frequency and the excitation frequency. Moreover, the average acceleration was defined to evaluate the movement of the drill string in a period of time.
The results indicate that rotary speed is the determining factor of drill string's lateral vibration. The lateral vibration frequency is equal to the excitation frequency and the average acceleration generally increases at a relatively low rotary speed. As the rotary speed continues to increase, when it exceeds a certain critical point, the lateral vibration frequency doubles and the average acceleration encounters a shape increase. In addition, with the increase of the weight on bit (WOB), the vibration frequency and the average acceleration keep stable, but the phenomenon of doubling the vibration frequency is suppressed.

Abstract
Shell Malaysia embarked on a Low-Cost Exploration and Development (LCD) journey to unlock previously stranded accumulations in the Central Luconia province. By leveraging on the long history of exploration and sub-surface data, a successful exploration campaign with Joint Venture (JV) partners yielded five field discoveries. The current Low-Cost Development strategy focuses on developing these fields with the JV partners through standardized lean well-head platform (WHP) tie-back to existing infrastructure. This paper describes the journey and the paradigm shifts within the company and its JV partners to achieve a WHP design that is low cost, light weight and replicable for future exploration discoveries.
Front end loading work and competitive scoping is applied to establish minimum requirements for safety and operability resulting in barebones functionality with many functionalities removed or scope reduced. This includes evaluating novel technology application such as solar panels for power versus the conventional turbine generators. A key paradigm shift within the company is to challenge company standards and to reconcile the gap between company and industry standards. Company standards are prevalent in the oil and gas industry with standards differing for various operators. A key effort undertaken by the project team is to strip down the differences in company standards and requirements between the various JV partners and industrial standards. To capitalize on the market environment of low oil price, the project steers away from conventional segmented contracting strategy with an EpC approach with competitive bidding to leverage on contractor's capability to further bring down cost.
The outcome of the competitive scoping and the focus on minimum functional requirement is a lean standardized WHP design, half the weight of recent WHP development projects without compromising safety and operability. The standardized WHP design is replicated for three fields within the same PSC resulting in reduced FEED engineering costs and shortened project cycle for future developments. CAPEX reduction is anticipated through leveraging on economy of scale for procurement of materials and equipment as a result of the replication of standardized WHP design.
With this approach of standardized minimum requirement WHP, it allows for new strategy for future field explorations and development by focusing on clustered exploration around the vicinity of existing infrastructure allowing for stranded marginal accumulations to be developed.
Storable Liquid-Bead System as Lightweight Additives for Oilwell Cementing

Published: March 2018

Abstract
Hollow-glass microspheres (beads) are widely used during oilwell cementing operations to produce lightweight cement slurries; this paper discusses a new method of blending hollow-glass beads into cement slurries by creating a storable liquid suspension of hollow-glass microspheres (liquid beads). This new method enables efficient delivery of lightweight cement slurries in offshore and remote locations by eliminating bulk-blending logistics.
The concept of liquid beads is not new; however, earlier attempts to develop liquid beads or similar products generally failed to address the storability problem. The buoyancy force tends to lift the beads to the surface of the suspension, forming a gel or crust and causing the mixture to lose flowability within a relatively short period of time. A special chemical-additive package developed in this study significantly extends the storability of liquid beads. This paper compares the gelation time of different liquid-bead formulas and evaluates the performance of cement slurries prepared with liquid beads.
Laboratory test data show that the chemical-additive package developed in this study can extend the storage time (shelf life) of liquid beads from a few hours to at least one month without reagitation at room temperature; the shelf life can be further extended to at least one year with regular reagitation of the mixture. Cement slurries prepared with dry-blended beads and those prepared with liquid beads exhibit similar performance in terms of laboratory test results, such as free fluid, fluid loss, thickening time, and hydration kinetics. The liquid-bead system developed can be produced with cement batch mixers for field use and remain stable in tote tanks for at least several months with regular recirculation. Liquid beads can be added to cement slurries through liquid-additive pumps during a cementing operation.
A novel liquid-bead product that can be stored for extended periods of time without separation is presented here along with necessary laboratory testing, actual field applications, and field-application case histories using liquid beads to produce low-density cement slurries.
Reservoir Monitoring by CSEM Data: A Fictitious Domain Strategy
Authors: Amani S. , Mikada H. , Takekawa J. 
Published: March 2018

Abstract
Marine controlled source electromagnetic (CSEM) survey is a novel complementary geophysical method for exploring structure below the seafloor. In this research, the processing of marine CSEM data is investigated for monitoring of hydrocarbon reservoirs in the offshore. Due to highly conductive seawater and shallow conductive layers, the attenuation of any EM signals is one of the most crucial problems that has prevented the application of imaging technologies (e.g. migrations) regularly adopted in exploration seismology. Inspired by the similarity of seismic and electromagnetic data, we investigate an innovative approach by applying two popular seismic imaging methods on CSEM data for monitoring of hydrocarbon reservoirs in conductive (attenuating) media: reverse time migration (RTM) and Kirchhoff migration (KM).
The synthetic marine CSEM data is calculated for a model including a hydrocarbon reservoir in an attenuating medium. We used the realistic values for sedimentary rocks that are common for attenuating media. Then, we apply RTM and KM methods to CSEM data in the real-time diffusive domain to monitor the hydrocarbon reservoir. In marine CSEM surveys it is important to consider the direction of source implementation and here we model the effects of source implementation directions in terms of reservoir monitoring. Maxwell's equations were solved in the fictitious wave domain, a scheme allows faster calculations than conventional methods, reducing the computational cost. However, the wavefields calculated using this fictitious method are not real and should transferred to the real-time diffusive domain.
The results confirm the RTM handles both the vertical and horizontal edges and defines the hydrocarbon reservoir in attenuating media much better than KM since the RTM does not introduce any approximations of the physics of wave propagation. The main drawback of RTM, its expensive computational cost, has been significantly reduced by advent of new powerful computers., The results also show that the horizontal source implementation is a better scheme for reservoir monitoring using a marine CSEM survey.
