Investigation of PDC Cutter Structural Integrity in Hard Rocks
Authors: Rahmani Reza , Pastusek Paul , Yun Geng , Roberts Tom 
Published: August 2020

Summary
Robustness of round and V-shaped polycrystalline diamond compact (PDC) cutters against mechanical and thermal load was evaluated. Forensic analysis was used to estimate the range of loads and depths of cut (DOC) that cause structural overload of PDC cutters. Finite-element analyses (FEAs) were calibrated against these data and used to estimate the integrity of cutters. Thermal-abrasive wear was tested with single cutter tests on Sierra White granite with and without cooling for multiple material grades. The axial and tangential impact resistances were evaluated with drop and front face impact tests. In addition, full-scale laboratory drilling tests were conducted in granite [unconfined compressive strength (UCS) = 28,000 psi] and quartzite (UCS = 56,000 psi). Finally, failures for round and V-shaped cutters were evaluated in field trials.
The V-shaped cutters scored similar to baseline cutters in thermal-abrasive tests but lower in axial impact tests. They also failed at 13 to 18% lesser tangential load. By accounting for 16% reduction in contact area between the shaped cutter and load anvil, it was concluded that both cutter geometries fail essentially at the same stress. In all full-scale tests, round cutters failed before the shaped cutters. This was in contrast with drop tests and is attributed to the shaped cutter's cutting efficiency, resulting in lesser load on the cutters for the same rate of penetration (ROP). The results were compared with field runs in hard and interbedded application in Oklahoma and west Texas. The conclusion based on FEA, laboratory, and field data was that in most cases, this shaped cutter shows the same or better dull as its base grade.
Automated Well-Log Processing and Lithology Classification by Identifying Optimal Features Through Unsupervised and Supervised Machine-Learning Algorithms

Published: August 2020

Summary
The application of specialized machine learning (ML) in petroleum engineering and geoscience is increasingly gaining attention in the development of rapid and efficient methods as a substitute to existing methods. Existing ML-based studies that use well logs contain two inherent limitations. The first limitation is that they start with one predefined combination of well logs that by default assumes that the chosen combination of well logs is poised to give the best outcome in terms of prediction, although the variation in accuracy obtained through different combinations of well logs can be substantial. The second limitation is that most studies apply unsupervised learning (UL) for classification problems, but it underperforms by a substantial margin compared with nearly all the supervised learning (SL) algorithms. In this context, this study investigates a variety of UL and SL ML algorithms applied on multiple well-log combinations (WLCs) to automate the traditional workflow of well-log processing and classification, including an optimization step to achieve the best output. The workflow begins by processing the measured well logs, which includes developing different combinations of measured well logs and their physics-motivated augmentations, followed by removal of potential outliers from the input WLCs. Reservoir lithology with four different rock types is investigated using eight UL and seven SL algorithms in two different case studies. The results from the two case studies are used to identify the optimal set of well logs and the ML algorithm that gives the best matching reservoir lithology to its ground truth.
The workflow is demonstrated using two wells from two different reservoirs on Alaska North Slope to distinguish four different rock types along the well (brine-dominated sand, hydrate-dominated sand, shale, and others/mixed compositions). The results show that the automated workflow investigated in this study can discover the ground truth for the lithology with up to 80% accuracy with UL and up to 90% accuracy with SL, using six routine well logs [vp, vs, ρb, ϕneut, Rt, gamma ray (GR)], which is a significant improvement compared with the accuracy reported in the current state of the art, which is less than 70%.

Authors: Onyeabor Samson , Zalewski Pawel 
Published: August 2020

Abstract
The objective is to investigate the importance of safety devices in mitigating the risks of emission (Fire, Smoke, Heat radiation and Noise, etc) associated with gas flaring during the LNG channeling and recovery mechanisms. The methods adopted is step by step investigative analyses of environmental considerations by looking at how various components (enclosures, flare tips, pressure relief valves, pilot ignition and detection systems of different types of flare systems (onshore/offshore) are designed and applied to monitor and analyze the fire and environmental risks generated during gas flaring and reduction as well as the disadvantages of these component applications. Such demerits range from faulty equipment, unsuitable devices, operating costs, lack of technical know-how and non-compliance to environmental regulations. Various results are acquired from both detection and monitoring devices. For a smoke-less operation to be achieved, the blower connected to the air-assisted flare tips must supply air to the flare system ranging within the fraction of 3/20-1/2. In reducing fire risks, the thermocouples are connected with retracted system to maintain change of components while the flare is still in operation. With respect to heat radiation, optical system like the flare monitoring telescope with optical diameter of 64mm was used to take the readings of the following light bandwidth: 6562.8, 6563.6, 6562.0 and 6562.8 and any data above 6564.0 was interpreted as high (increase in heat radiation). Poseidon and Coanda (highly improved) devices were also used for further monitoring and data/graphs generated for interpretation and summary. These will all be elaborated to ensure that all participants appreciate how the safety devices control gas wastes and prevent reduce environmental risks and the roles of pilot detection and monitoring system and integrated fire and gas detection systems in investigation and control of possible fire risks in any industrial plant.

Abstract
The concept of Safety Case administration in oil and gas operations was one of the important fallouts from the public enquiry of Piper Alpha incident which happened in 1988 in the North Sea and claimed the lives of more than one hundred and fifty (150) personnel. Safety Case is a document which its process of preparation and approval ensures that operators or facility owners not only become aware of hazards in their operations but also put in place adequate mitigations to reduce the risk of accident occurrence to as low as reasonably practicable (ALARP), thereby assuring themselves and demonstrating to stakeholders (especially the relevant regulatory authority) that their facility is safe to operate or safe to continue in operation. Against this backdrop, the government has made the development and implementation of Safety Case a requirement for all installations operating, or to be operated, or to be decommissioned in the Nigerian oil and gas industry. Nigeria’s oil and gas industry regulator (Department of Petroleum Resources – DPR) established the Safety Case Regime as a means of ensuring, validating and tracking measures put in place by operators and facility owners towards mitigating the inherent risks posed by their oil and gas installations in Nigeria. This paper therefore examines the key elements as well as benefits in the implementation of the Safety Case regime in Nigeria by evaluating the extent of compliance amongst the operators and identifying common problems facing operators in the preparation of a Safety Case for submission. The basic contents of a typical safety case, step-by-step implementation procedure, and the approval criteria were reviewed with recommendations made to improve the overall process.
Experimental and Simulation Studies on the Use of Plant Oils as Flow Improver for Waxy Crude Oil
Authors: Olusegun Samuel , Omoladun Ruqayah , Alade Olalekan , Taiwo Elijah 
Published: August 2020

Abstract
Alteration of thermodynamic equilibrium conditions, most especially, temperature, during production and transportation of crude oil could cause destabilization, precipitation, and deposition of wax. This could affect the flow properties of the crude oil including the viscosity, pour point, and may eventually cause total blockage of the flow lines. In this investigation, synthetic waxy crude oil (containing different concentrations of dissolved paraffin wax (5 – 20% wt./wt.) was doped with selected plant seed oils, namely, Castor oil, Moringa oil and Coconut oil (0 – 1.5% v/v). The efficiency of each of the additives to improve the flow properties was compared with those of commercial flow improver, Triethanolamine (TEA). In addition, similar process was modelled and simulated using HYSYS process simulator. It was found that Moringa and Castro oils show good results to improve the pour point. On the other hand, the Coconut oil was observed to have negative effect by increasing the pour point of the oil. Ultimately, experimental studies reveal the potential of the plant oil to improve the flow properties of the waxy oil, while the simulation studies confirm the potential of the plant oil to reduce wax deposition volume and thickness, viscosity, and total pressure drop.

Abstract
Inflow control devices (ICD) have been used to balance flux around completions and also delay break-through of unwanted water into completions. Inflow-control devices (ICDs) were provided to curtail water production from heterogenous reservoirs with strong aquifer systems and/or supported with water injection. The model for the ICD consists of pressure-drop equations from the reservoir, through the screen, the flow conduit, the ICD nozzle, and into the production tubing, along with pressure drop through the lower-completion system. This additional pressure drop does not contribute to additional fluid inflow into the wellbore and this is seen to be an impairment to the productivity of horizontal wells. Pressure losses from horizontal wellbores which do not contribute to increased production is seen as skin and consequently, a new equation was derived to estimate skin due to ICD in horizontal completions.
In this paper, a horizontal well equipped with inflow control device which was drilled in one of the off-shore fields of the Niger Delta region was used as a case study in evaluating the performance of an ICD completion. The new equation was used to estimate the skin due to ICD of this completion and the result obtained is compared with the skin obtained using pressure transient analysis and the results obtained from both approach are similar. This paper shares how the new equation was used to estimate skin due to ICD and the result comparison with that of a pressure transient analysis.
Spatial Variations of Latent and Other Forms of Heat in a SAGD Process
Authors: Lawal Kazeem A. , Olamigoke Olugenga 
Published: August 2020

Abstract
Steam-assisted gravity drainage (SAGD) is characterized by the development and expansion of a steam chamber. It is generally assumed that all points within a steam chamber are at same temperature as the injected saturated steam. Hence, the view that the injected steam releases the full latent heat corresponding to its injection temperature. Leveraging on relationship between steam latent heat and temperature, as well as that between saturation temperature and pressure, this paper interrogates the general view that a constant amount of latent heat is released at all points within a steam chamber. We formulate and simulate a new mathematical model that reveals why and how the net specific latent heat released varies across a steam chamber. For completeness, a similar analysis is extended to examine the spatial variations of sensible and total heats in a SAGD. From parametric tests performed, spatial variations of the effective latent, sensible and total heats in a SAGD are quantified. The parametric tests show that the spatial variations of effective latent, sensible and total heats released are more sensitive to in-situ steam temperature than density contrast. For the range of density contrasts examined, simulation results suggest that the spatial variations are more pronounced at steam temperatures less than 150 °C. At higher temperatures, at which most SAGD and steam-based recovery processes are operated, spatial variations of the specific latent, sensible and total heats of steam are found to be negligible. These findings provide a technical basis not to operate SAGD and other steam-based recovery techniques below 150 °C.
Digital Transformation: After the Big Data, What Next?

Abstract
Our definition of ‘The Big Data’ is the ability of having all the data set at the point of decision-making. Several documented research shows that less than 5% of all the data acquired in the oil and gas industry are actually utilised. Despite these challenges most operating assets, still keep acquiring more data and creating data-load that are never utilised or put into use. This paper aims to demonstrate the reason(s) why we have this data-load and instigate a solution path in managing this challenge for value realisation.
Data is a corporate asset in any organisation but the default ‘silo’ work culture in most operating asset makes it difficult to get the relevant insight from these data. Organisation must be deliberate in creating the right data architecture from the data process domain through into the distributed control system, into the data historian, then within the data platform and the visualization realm and finally into the workflow domain. It is at the workflow domain that we get the ‘game-changer’ otherwise called value. This is the differentiating factor in delivering the ‘Big Data’ into the space of benefit realisation. This was what was achieved in a field in Niger Delta and has been shared compared to global best practice.
The documented result from this case study showed that any data architecture should be framed to address asset business need, right from the data process domain function through to the data historian into the workflow level where the business objective is addressed. Data must be application-centric accounting for scalability, accessibility, security and business performance.
Assets need to be clear on why they are acquiring data and not just continuous acquisition of more data with the resultant effect of data-load without answering the question; what next after data acquisition? This paper provides the answer of what next after data acquisition and serves as a quick reference tool for similar challenge elsewhere, not limited to the oil and gas industry.

Abstract
Recovery agent formulated from a bio-based polymer and surfactant was targeted at extracting stuck reservoir fluid. Synthesized Methyl ester sulfonate directly from castor Oil was reacted at altered concentrations with Guar gum. With an important advantage involving a dual chemical component processing high viscosities with dual recovery nature that influences interfacial tension(IFT) and improvement of mobility ratio. Adsorption of surfactant on Berea sandstone noticeably reduced after engaging this blend. The performance was studied by Core flooding, and Rheological studies. Enhanced Oil Recovery (EOR) process was conducted employing with Berea sandstone cores as the porous medium with OFITE®'s reservoir permeability tester(RPT). EOR efficiency using this combination gave more recoveries ranging from 58-72% of the initial oil in place after water flooding and also a comparism was achieved with conventional surfactant and Polymer.
