Technology Focus
I am very excited to begin my term as editorial reviewer for Completions. JPT has always been the source of cutting-edge information on industry technology developments, and I pledge to continue that tradition through expert review and selection of articles.
Our industry is showing signs of emerging from the recent downturn, and commodity prices are slowly improving. There is intense focus across the industry on profitability in the current low-oil-price environment, and profitability must be achieved while meeting regulatory requirements, delivering value to stakeholders, and attracting and retaining the best talent available. Yet, today’s profitability is not the only challenge. Laying the groundwork for future profitability must also occur.
One of the more powerful tools available to help achieve sustained profitability is innovation, and it has consistently generated cutting-edge technologies that have advanced the oil and gas industry.
The good news is that innovation has continued during the downturn. For example, advancements in dissolvable-materials technology and downhole data acquisition have continued. While the former primarily advances efficiency in multizone shale well completions, the latter will advance effectiveness in both land and offshore completions. Process innovation is also occurring and is evident in the drive to create advanced numerical models for optimization of stimulation and hardware choices in multizone shale well completions. Finally, increased focus on reliability in design, installation, and operation has emerged, as both operators and suppliers recognize the contribution of risk management to completion technology and systems.
The articles in this month’s Completions section are great examples of how innovation is driving profitability, and I hope that they help you drive profitability in your completions.

Embedding Automatic Risk-Level Estimation and Performance Analysis in Drilling Plans
Authors: Wilson Adam 
Published: August 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper SPE 181018, “Automatic Performance Analysis and Estimation of Risk Level Embedded in Drilling-Operation Plans,” by Eric Cayeux, SPE, and Benoît Daireaux, SPE, IRIS; Mohsen Karimi Balov, Statoil; Stein Haavardstein, ConocoPhillips; Leif Magne Stokland, Wintershall; and Arild Saasen, SPE, Det Norske, prepared for the 2016 SPE Intelligent Energy International Conference and Exhibition, Aberdeen, 6–8 September. The paper has not been peer reviewed.
It is not unusual that the difficulties encountered during a drilling operation can be tracked to choices made during planning. However, generating a robust drilling-operation plan is not easy because substantial uncertainties are often associated with the actual geological context. To address this problem, this paper presents a method that quantitatively evaluates the risk levels of a drilling-operation plan as a function of the underlying uncertainty associated with its description.
Introduction
A drilling operation is always subject to operational risks (e.g., formation-fluid influx, lost circulation, borehole instability, packoff, stuck pipe, or drillstring failure). The chance of occurrence of some of those threats may be small in a particular well design. But, in other configurations, it may be known already at the planning stage that potential drilling problems are likely, because of tight operational margins for instance.
The drilling challenges also may be aggravated by uncertainties in the geological context.
Making a robust drilling-operation plan is a challenge, and there are many reasons for this. One of them is connected to the difficulty in evaluating quantitatively, at the planning stage, the effect of uncertain information on the effective risk levels that may prevail during well construction. Quantitative risk assessment with management of uncertainty has been described for specific tasks, such as choosing a mud weight as a function of an uncertain geopressure window. The more risks that are simultaneously evaluated within the expected uncertainty of the coming operation, the greater the chances are that the proposed drilling-operation plan will be robust.
Drilling-Operation Risks
Numerous sources of risk exist in a drilling operation, and the quality of the evaluation made by the proposed risk-evaluation method is directly related to treating as many threat sources as possible. However, it is an overwhelming task to manage all of the conceivable potential sources of drilling problems at once. For this reason, the authors decided that, as a first step, only a subset of possible causes of drilling incidents will be considered. The causes from this initial list are associated with typical problems encountered in drilling operations in the North Sea.
Technology Focus: Oilfield Chemistry

Technology Focus
A true structure performance understanding of asphaltenes and the chemical methods used to control them has eluded the industry for many years. Despite many hundreds of published works (and no doubt many more unpublished studies), there is still no singular technique that can definitively characterize a crude oil for asphaltene risk and control that is scalable to the field.
The answer to why this is lies in the sheer complexity of the asphaltene molecule itself and, just as important, the variances in asphaltene type and content from crude to crude. As production chemists, we have relied upon generalizations born from seminal academic and industry studies over the last 3 decades. For instance, asphaltenes are polar, asphaltene precipitation very much depends upon pressure and the change of that throughout a system, and asphaltene-control chemicals are dispersant in action. But how does the exact mechanism of adsorption onto a surface take place, and how can we prevent it? These idiosyncrasies still cause much debate among academics and industrialists alike.
Much work remains to be done to get the final answers. The sheer complexity of the asphaltene molecule is now within our grasp as the digital age creeps up on our industry. Having the analytics to decipher and measure asphaltene structures and then use high-throughput techniques to determine structure performance relationships gives us a chance to accelerate our understanding.
The featured papers summarize some of the state-of-the-art techniques in use—techniques to determine the onset of asphaltene precipitation, adsorption, and inhibition. Readers are encouraged to research the recommended additional reading and take some time to delve into the references contained in these papers. These papers contain an extensive review of the history of, and current state of the art in, asphaltene science for the oilfield chemist and engineer.

Monitoring and Mitigating Asphaltene Issues in a Deepwater Production System
Authors: Wilson Adam 
Published: August 2017

This article, written by Special Publications Editor Adam Wilson, contains highlights of paper OTC 27123, “Strategies To Monitor and Mitigate Asphaltene Issues in the Production System of a Gulf of Mexico Deepwater Subsea Development,” by Doris Gonzalez, Fabio Gonzalez, Marney Pietrobon, Mehdi Haghshenas, Megan Shurn, Amber Mees, Carlos Stewart, SPE, and Chinenye Ogugbue, SPE, BP, prepared for the 2016 Offshore Technology Conference, Houston, 2–5 May.

An asphaltene threat was identified in production wells located in a Gulf of Mexico deepwater field. During reservoir-fluids characterization, asphaltenes were identified as a key risk factor for successful field development. This paper presents an integrated approach to evaluate the key elements of asphaltene risk for deepwater projects, the strategy to manage the issues during production implementation, and aspects to be considered in the mitigation of asphaltene in the field-development plan.
Introduction
Asphaltene precipitation and deposition can occur at different stages during petroleum production, causing reservoir formation damage and plugging of pipelines and production equipment.
Remediation of asphaltene deposits requires solvent-soaking operations, followed by removal through exposure to turbulent flow. These intensive operations require high amounts of chemical solvents with potential effects on health, safety, and environment, along with production deferrals because of operations downtime.
The focus of this study is to understand the effects of asphaltene precipitation in a Gulf of Mexico deepwater field. The approach is based on reservoir-fluid characterization and monitoring tools. Being able to predict the presence and type of trouble zones along the production system from downhole to production facilities is becoming progressively more important as water depths increase.
Acquisition of Downhole Fluid Samples
High-quality pressurized bottomhole samples were collected for asphaltene-onset-pressure (AOP) and wax-appearance-temperature (WAT) measurements in pressure-compensated chambers. Because the samples tend to cool to below reservoir temperatures as they are retrieved from the well, the samples were maintained at pressures above reservoir condition at all times to reduce the possibility of irreversible asphaltene precipitation resulting in non-representative samples.
Asphaltene Prescreening
The de Boer Plot. The de Boer plot is a method to screen crude oils for their tendency to precipitate asphaltenes. It essentially evaluates the loss of asphaltene solubility as a reservoir-fluid sample is depressurized. This pressure/volume/temperature screen is a crossplot of in-situ density and the degree of undersaturation with respect to gas (the difference between reservoir pressure and saturation pressure). Because this screening assumes that the fluid is saturated with respect to asphaltene at reservoir conditions, it is extremely conservative.
Human Umbilical Cord Blood Serum Has Higher Potential in Inducing Proliferation of Fibroblast than Fetal Bovine Serum
Authors: Sandra Ferry , Lahirin Rita 
Published: August 2017

Background: Cytokines and growth factors were reported to play an important role in stimulating fibroblast proliferation. In vitro culture, fibroblast is mostly culture in medium containing fetal bovine serum (FBS). Human umbilical cord blood (hUCB) has been reported to have low immunogenic property and potential in wound healing, so therefore hUCB serum (hUCBS) could be potential and were investigated in current study.Materials and Methods: Five hUCBs were collected from healthy volunteers with normal delivering procedure. hUCB was ex utero immediately collected from umbilical vein in vacutainers and processed. NIH3T3 cells were cultured in DMEM with 10% FBS or 5-20% hUCBS for 48 hours. Cells were then quantified using MTT assay. Protein concentration of FBS and hUCBS were quantified using Bradford assay.Results: NIH3T3 cells density grown in DMEM with 10% FBS was the lowest. NIH3T3 cells densities were increased along with the increment of hUCBS concentrations. MTT results showed that average number of NIH3T3 cells grown in DMEM with 10% FBS was 6,185±1,243. Meanwhile average numbers of NIH3T3 cells grown in DMEM with 5%, 10% and 20% hUCBS were 8,126±628, 9,685±313 and 12,200±304, respectively. Average numbers of NIH3T3 cells grown in DMEM with 5% hUCBS were significantly higher than the ones with 10% FBS (p=0.000). Bradford results showed that concentration of hUCBS was significantly higher than the one of FBS (p=0.000).Conclusion: hUCBS could induce higher proliferation rate of NIH3T3 cells than FBS. Hence hUCBS could be suggested as an alternate of FBS in inducing fibroblast.Keywords: NIH3T3, fibroblast, UCB, serum, FBS, proliferation

Authors: Silakhudin Silakhudin 
Published: August 2017

This study discusses about the thin layer activation technique to test the mechanical components wear level. The results of preliminary experimental techniques are presented. The experimental results of the technique by using a motorcycle ring samples showed that the accuracy of measurement of the wear is 8 mg. This means that it will be less precise for testing the lightweight components. It will be more eligible to the component that the weight is more than 220 g. The prospect of developing the technique was also discussed; the result is that this technique would be appropriate to be developed at the DECY-13 cyclotron facility that will soon be constructed in BATAN
THE EFFECT OF THE GRAIN SIZE AND THE TYPE OF FLUIDS FILLING THE PORE OF IRON SAND TOWARD ITS MAGNETIC SUSCEPTIBILITY
Authors: Ipa Sangaji Hasmi Maharani 
Published: August 2017

This study was aimed at assessing the effect of grain size and type of ﬂ uid ﬁ lling the pore to its magnetic susceptibility value. Iron sand was separated based on the grain size into 0.5 mm, 0.25 mm, 0.125 mm and 0.074 mm and based on the condition; namely dry, mixed with distilled water and salt water. Some measurements were done in the laboratory using Bartington MS2 Susceptibility Magnetic Meter and XRD (X-Ray Diffraction). Bartington MS2 Susceptibility Magnetic Meter is used to measure the magnetic susceptibility of each grain size in all conditions, while XRD is used to identify the type and the concentration of minerals contained in each size of iron sand. Iron sand with the smaller grain size and high concentration of magnetite mineral will increase the value of magnetic susceptibility and its density. In addition, the type of ﬂ uids that ﬁ lls the pore of each size also gives the variations of the magnetic susceptibility.
