Published: October 2018

Permasalahan dalam pengelolaan induk ikan sepat siam adalah kurang maksimalnya derajat penetasan telur yang hanya mencapai 80,03 %. Salah satu cara yang dapat dilakukan adalah dengan memperbaiki kualitas telur melalui perbaikan kualitas pakan yang diberikan kepada calon induk ikan sepat dengan penambahan bahan suplemen dan imbuhan pakan. Penelitian ini bertujuan untuk mengetahui respon reproduksi induk betina sepat siam terhadap penambahan bahan suplemen dan imbuhan pakan, seperti: minyak ikan, vitamin E serta ekstrak temulawak. Ikan uji adalah induk betina sepat siam dengan usia minimal 8 bulan dan berada pada tingkat kematangan TKG I atau TKG II. Pakan penelitian yang digunakan ada 3 macam yaitu pakan komersial dengan penambahan minyak sayur (FCO), pakan dengan penambahan minyak ikan dan vitamin E (FOT) dan pakan dengan penambahan minyak ikan, vitamin E serta ekstrak temulawak (FOTG).Hasil menunjukkan bahwa pakan FOT dan FOTG dapat mengasilkan indeks gonadosomatik (IGS), fekunditas, diameter telur, derajat penetasan telur dan survival rate yang lebih baik daripada pakan FCO. Hal ini terjadi diduga karena pengaruh dari penambahan vitamin E yang berfungsi mencegah oksidasi dari asam lemak, sehingga lemak yang ada dapat digunakan sepenuhnya. Akibatnya, kualitas dan kuantitas telur jadi meningkat. Nilai IGS pada semua perlakuan berkisar antara 3,07 – 3,57 %, fekunditas berkisar antara 3.875 – 5.355 butir, diameter telur berkisar antara 0,70 – 0,93 mm, derajat penetasan berkisar antara 78,12 – 89,58 % dan survival rate berkisar antara 51 – 83 % pada semua perlakuan. Pakan dengan penambahan minyak ikan dan vitamin E dapat menghasilkan diameter telur dan survival rate yang lebih baik, sedangkan pakan dengan penambahan minyak ikan, vitamin E serta ekstrak temulawak dapat menghasilkan nilai indeks gonadosomatik (IGS), fekunditas dan derajat penetasan telur yang lebih tinggi.

Abstract
Well ‘A’ is a horizontal well drilled in the primary and productive upper layer of the carbonate reservoir just below 7,750 ft TVD, with lateral length of 3,495 ft. This layer, due to inherent well placement, presented completion and production challenges attributed to low permeability and with limited scope for production enhancement. The asset team required an effective solution to drain reserves from this well and for evaluating future well placements.
Near-wellbore (NWB) acid stimulation technique was preferred over conventional acid fracturing due to low vertical stress contrast and high tortuosity effects caused by lateral azimuth relative to maximum stress orientation. Based on the Bernoulli concept for fluid diversion and using a dual path pumping system, initiation and propagation of micro-fractures was achieved by pumping fluid through tubing and annulus with a controlled pump schedule. A specially designed high-pressure tool was used for creating formation cavity by pumping acid through tubing. Increasing pressure on the bottom of cavity initiates micro-fracture causing annular fluid to be pulled into the fracture and subsequently extending it.
The NWB stimulation was designed and carried out in 50 stages along the lateral. This was followed by 29-stage matrix acid stimulation using 20% HCl and with pulsonix tool for acid placement. Initial well productivity (PI) was estimated at 0.16 STB/D/psi. Post stimulation treatment resulted in a nine-fold PI improvement. Production post stimulation was 720 barrels oil per day (bopd) with 7% water cut (w.c).
The NWB stimulation enabled significant productivity increment with accelerated production. It is customizable enabling design and placement of multiple micro-fractures. Additional hardware for wellbore isolation during treatment is not required. It is economical in comparison to conventional fracturing treatment and could be extended for cased or liner completions in vertical or deviated wells.

Erosion Resistance of Sand Screens in Gas Wells

Published: October 2018

Abstract
A few cased-hole gas wells in Southeast Asia that were initially completed without any sand control are now producing sand, and the operators want to remediate these wells via standalone sand screen inside the production tubing. In these wells, the fluid (gas/sand) produced through the perforations would impinge rather directly on the screen, and erosion of the screens could be one of the major concerns. Therefore, a project was undertaken with the main objective of comparing the gas-erosion resistance and sand control efficiency of different types of sand screens via laboratory experiments.
The results demonstrate that the erosion resistance was dependent on the screen type, gas velocity, and particle size distribution of the abrasive media (sand). Poorly sorted sand with more fines exhibited more damage than well sorted uniform sand, emphasizing the importance of right sizing of sand to minimize screen damage. The erosion lifetime of the screens was ranked as: bead screen &gt; mesh screen &gt; wire-wrapped screen. The time to failure for the bead screen was at least 2.5 times higher than the premium mesh screen protected by a louvered shroud, while the wire wrap screens only lasted a fraction of time before losing its sand retention capacity. However, sand plugging was found to be a concern for the bead screen, suggesting that it must be behind another primary sand control such as gravel packing to protect it against plugging, and would be very effective fail-safe sand control device under such configuration. The louver design shroud protecting the mesh screen proved to be ideal for sand producing gas wells due to its moderate erosion resistance, low concerns due to sand plugging, and high sand control efficiency.
SMARTDRAIN: An Intelligent Workflow for Well-Placement Optimisation by Integrating Streamlines Time-of-Flight and Exhaustive Search Algorithm

Abstract
Optimal well placement remains both highly challenging and significantly important in the E&P business since they impact field development decision making. Conventionally, well placement is performed manually based on well spacing, which may not capture the effect of reservoir geology effectively, especially in cases of high reservoir heterogeneities. Modern techniques tackle this problem by treating well locations as discrete optimisation problems through reservoir simulations, and thus apply heuristic algorithms to search for optimal well locations. However, these methods require considerable computational effort, which forestall any efforts at novel techniques in searching to for global optimal solutions.
This paper presents an innovative well placement optimisation workflow to minimize the calculation time of simulation using drainage volume via streamlines time-of-flight. A reservoir simulation is run for a short period of time to acquire streamlines for all proposed well locations. The time-of-flight property, along streamlines, indicates the theoretical time required for a theoretical tracer particle to move along each streamline to a producer (pressure sink). The time-of-flight, together with reservoir properties, are then used to calculate the hydrocarbon drainage volume from each producer. In which, it is the key parameter to suggest that how much hydrocarbon can move to wells with a given production period. This workflow will search for optimal well locations to maximize the hydrocarbon drainage volume with a given number of wells.
The approach translates reservoir simulation to numerical matrix union optimisation, which can be carried out at an extremely fast computational speed (less than a second for a single iteration). The expedited calculation efficiency allows exhaustive search algorithms to evaluate millions of possible well combinations and can, consequently, guarantee a global optimal solution. The workflow has been conceptually proven with a synthetic 2D simulation model, providing a pattern-like scheme to mimic the conventional approach. Furthermore, it has been successfully tested with field scale reservoir simulations. The algorithm demonstrates the advantages of optimized well-placement over conventional methods without much of an increased computational burden.
The workflow is also designed to be automated with a simple user-interaction via MATLAB and MS-Excel; namely, the SMARTDRAIN package. This allows engineers/geologists to implement it as a generic workflow without requiring extensive knowledge in mathematical algorithms. With such calculation efficiency and improved optimal solution, this approach can be applied as a new well placement optimisation standard that would add competitive value in field development planning and optimisation.
High-Performance Water-Base Fluid Performs As An Environmentally Friendly Alternative To Oil-Base for Drilling Challenging Intervals In North Kuwait

Published: October 2018

Abstract

Objectives/Scope
A major Operator in Kuwait have used historically Non-Aqueous Fluid (NAF) to drill the buildup section through the challenging shale formations, mainly due to wellbore stability issues and lubricity requirements. As part of the operator's environmental improvement strategy, the operator and fluids provider team identified potentially fit for purpose High Performance Water Base Mud (HPWBM) as the most suitable, environmentally acceptable alternative to NAF’s.

Methods, Procedures, Process
A HPWBM system was designed and proposed based on extensive laboratory testing to overcome drilling challenges. Inhibition characteristics and formation sealing capabilities of conventional KCL polymer mud with sulphonated asphalt were enhanced by using a liquid polyamine based clay hydration suppressant and a co-polymeric nano-sized shale-sealing additive. A customized bridging package based on the pore size distribution was also introduced, using calcium carbonate and resilient graphite particles. The combination of effective bridging and sealing polymer helped in sustaining high overbalance to avoid differential sticking tendency, designed in laboratory conditions during the planning stage.

Results, Observations, Conclusions
The field trial was a great success compared to the use of conventional fluid systems and methodologies. Using High Performance Water Base Mud, the operator successfully drilled and cased 12.25" and 8.5" sections as per plan with stable wellbore indicated by the smooth trips and no string stalling or sticking tendency. Drilled 1077 feet of 12.25-in hole section crossing Ahmadi shale and 683 ft. of 8.5" section crossing troublesome Wara shale without any well-bore instability issues even at high inclination. Also, while drilling across depleted Mauddud limestone with 1800-psi overbalance, no differential sticking tendency observed. Both sections were completed in record 11 days, fastest comparing to offset wells drilled with NAF.

Novel/Additive Information
In this paper, the authors will detail this novel approach of using an environmentally acceptable HPWBM system in the North Kuwait Basin, from planning to execution, which can be implemented further on the field and offers significant cost saving and reduces the risk of HSE issues related to Diesel based NAF systems.
Maximising Value of an Appraisal DST: Recording a 10,000 Hour Build-up in an Abandoned Well Using Wireless Downhole Gauges
Authors: Walters Stuart , Ward Gavin , Cullingford Mike 
Published: October 2018

Abstract
Reservoir connectivity over production timescales is a key uncertainty impacting estimated ultimate recover (EUR) per well, and ultimately the economics of a development, but is difficult to address without production data (particularly where the reservoir is poorly defined by seismic). While appraisal well tests can be designed to help predict the performance of future development wells, high rig costs in deepwater means the test duration is often insufficient to investigate the volume that would be accessed under production conditions. Recoverable resources from a recent deepwater gas discovery were dependent on demonstrating significant reservoir connectivity and net reservoir volume; however, this was complicated by a lower delta plain interval that was dominated by sub-seismic reservoir elements.
This paper describes the acquisition and interpretation of long-term pressure build-up data in a plugged and abandoned deepwater appraisal well. To accomplish the test objectives at an acceptable cost, we turned to a novel combination of well testing, wireless gauge technology and material balance techniques to allow the collection and interpretation of reservoir pressure data over a planned period of 6 to 15 months following the well test. The final build-up duration was 428 days (14 months).
Three interpretation methods of increasing complexity were used to provide insights into the reservoir. Firstly, material balance was used to produce an estimate of the minimum connected reservoir volume. The advantage of material balance is that it requires very few input assumptions and produces a high confidence result. Secondly, we used analytical models in commercial pressure transient analysis software to investigate near wellbore properties and distances to boundaries. Finally, we used finite difference simulation models to investigate reservoir properties and heterogeneity throughout the entire tested volume. With increasing model complexity came additional insights into the reservoir properties and architecture but reduced solution uniqueness.
A key complication for the interpretation of the recorded pressure data was the potential for gauge drift to occur – this was incorporated into the uncertainty range used in all three interpretation methods. The observed relative performance for the various gauges used during the well test is also reported in this paper.
Practical Application of Coalbed Methane Material Balance Technique to Produce Well by Well Production Forecast in Undersaturated Queensland Surat Basin Coals
Authors: Aibassov Gizat 
Published: October 2018

Abstract
Use of p/Z versus cumulative produced gas plots is an industry standard practice to estimate gas initially in place (GIIP) and expected ultimate recovery (EUR) for conventional volumetric gas reservoirs that behave as a "tank".
In this paper applicability of coal seam gas (CSG) material balance technique as proposed by King (ref 1) on Surat Basin undersaturated coals was investigated. A modified King's material balance technique, as well as the Jensen and Smith approach, were successfully applied to production data from undersaturated coals, producing robust dynamic GIIP and EUR estimates based on observed reservoir depletion trends.
Stability of produced GIIP estimates was tested by means of sensitivity analysis and robustness of the technique demonstrated by comparison with results of numerical reservoir simulation.
Finally, reservoir tank models were linked with the well inflow relationship to produce well by well production forecasts. The key difference of CSG wells, compared to conventional gas wells is that well productivity considerably changes during the life of a well. This gas productivity increase phenomenon was captured in the forecast by means of well PI versus recovery factor relationship. Thus, a practical CSG well by well production forecasting approach is proposed.
