Abstract
The ultimate goal of sand control design in producing hydrocarbons is to obtain solids free at lowest cost per barrel. Therefore, predictable production and its associated cost is vital to achieve the best business value. Previously, the prediction of production from sand control well is cumbersome. This paper presents the novel method which using the field data to provide the insight of sand control and deliver an optimal design for the sanding propensity well.
Gravel pack sand control designs involves many parameters and is a tedious process for an engineer to interact with several dynamics parameters. This novel method started with field data collection from previous sand control operations. The datasets are prepared into the structured form, then reservoirs are sorted based on their similarities and finally the parameters are selected based on their significance. These parameters are mapped onto the productivity index using a variety of modeling types. The prediction result show that the productivity index can be modeled with high statistic measure (i.e. R-squared). Ultimately, Net Present Value (NPV) derived from anticipated reserves are known before pumping the gravel pack job. The continuous improvement of datasets can significantly help improve the sand control design.
In this study, the novel method is presented using field dataset to optimize the sand control design. The design process can be driven with the use of data and machine-learning algorithms. This emerging technology allows greater insight into the day-to-day operations. The continuous adoption of this technology is a key enabler of futuristic industrial 4.0. The data-driven process empowers the oil & gas industry to become more durable, robust and competitive.
Fit for Purpose Connection Design for Drilling Operations in Size Constrained Tubular
Authors: Plessis Guillaume , Muradov Andrei , Griffin Richard , Dugas Jeremy , Orlando Justin , Delcambre Devin 
Published: June 2021

Abstract
Drilling out or working within small sizes of casing and liners requires the use of a drill string with small outside diameter tool joints to fit inside the casing/liner bore and, at the same time, a large enough connection internal diameter to pump actuating balls inside the drill string when needed. These requirements significantly limit the available options that can be used.
Historically, a drill pipe double shoulder connection with a 3⅛-in. outside diameter (OD) has been used for such operations, as it allows for multiple makeups and breakouts before it needs to be repaired. This is a great improvement compared to using small tubing premium connections that are somewhat limited on the number of makeups. However, the geometry constraints are such that the thin material envelope leads to torsional weakness in the connection, resulting in a higher than expected recut rate as connections can be overtorqued downhole in operation.
A research and development (R&D) project was commissioned to improve the connection performance significantly to mitigate the downhole overtorque. Exploring the acceptable connection envelope limits allowed for a slightly reduced internal diameter (ID) when compared to the previously used connection. The team considered different thread designs and decided to use the one that would provide the highest torque. The design process was then followed to develop and qualify a well-balanced connection.
The design validation was performed at an engineering technology center in Houston, Texas, where samples were destructively tested to compare the actual capacity of the new connection against the calculated values. It was confirmed that the torsional strength of the new design meets and exceeds the theoretical value, an improvement of at least 85% over the previously used connection, and a first string was built. It was subsequently deployed in the field and the recut rate was monitored to establish that the objective of delivering a connection capable of higher torque was indeed met to resist the downhole overtorque.

Abstract
Executing interventions in wells encrusted with wax is challenging because experience with global coiled tubing (CT) dewaxing operations is limited, and equipment failure and stuck pipe risks are high. With few jobs performed worldwide, CT dewaxing (hot oil circulation with CT) operations are largely unexplored. The deviated wells in a field in northeast India pose several challenges including completely seized wellbore due to paraffin/asphaltene deposition, previous failed well cleanout attempts, very slow and low bottomhole assembly (BHA) penetration, pumping corrosive and flammable low wax crude (LWC) through CT, high chances of CT getting stuck, and pumping heated 69°C LWC through the CT. This case study delivers insights about design, safety, and operational considerations for 1.5-in. CT dewaxing and nitrogen lift operations in a subhydrostatic well in the field. The objective of this CT dewaxing and nitrogen kickoff operation was to clear the well of paraffin/asphaltene/wax to 1600 m and activate it with nitrogen, and this paper describes solutions for cleaning out and nitrogen-lifting wells with declining production due to paraffin and asphaltene deposition. One well is described in this case study, but this approach can be used perform CT intervention in similar wells.
For this case, simulations were sensitized to identify the best combination of pumping rates, CT speeds, and fluid temperature to remove deposits hindering BHA penetration. This study proposes prevention measures using appropriate grounding and procedures, which determine if the crude oil can be pumped through CT. By use of this methodology, 581 dewaxing runs have been performed in 78 wells. Extensive on-job experience and lessons learnt by performing this operation over the last 3 years bring excellent results and prevent misruns. In many cases, production has been restored from nil; several examples feature a fivefold improvement of productivity thanks to this intervention method. Optimized operational parameters such as CT speed, pumping rates, and the use of smaller outer diameter BHAs doubled operational efficiency during those operations. In addition, strict application of the recommendations prevented the occurrence of operational problems such as stuck CT, crude oil flashing, sand bridging, and equipment failure.

Abstract
Reservoir navigation is a common and integrated part of the drilling process to steer wells very precisely. It is a requirement for many of today's complex deviated and horizontal development wells steered through challenging and small geological targets that can be as small as two metres in size. The capability is a key enabler for the oil industry and has contributed significantly to the prolongation of the economic well being of most oil producing provinces around the world.
In order to be successful, reservoir navigation must combine advanced downhole logging while drilling (LWD) tools, telemetry of LWD data to surface in real-time, the ability to steer while drilling, fit-for purpose software applications and perhaps most important of all, skilled personnel. That said, it is currently common practice for reservoir navigation to be performed with a dataset that is restricted to a vertical ‘curtain’ section derived from the development well. This is an unnecessary restriction that is often self imposed because of the limitations of the software applications being employed. With improving computer power, it can and should be superceded in favour of a more holistic approach.
The new reservoir navigation analytical processes are all designed to be performed at speed and in real-time while drilling the reservoir, on demand, at any stage, within minutes. These enhancements quantitatively illuminate the critical financial consequences of a well's geological drilling results. These are usually greater than the economic benefits of more efficient well operations. It means well owners can now operate in an information rich environment leading to better multi-disciplined team work and improved operational decision making. The benefit is better wells that produce more hydrocarbons at lower cost.
A real data set comparing a pre-well 3D model with realistic real-time geological updates and visualisations in three dimensions demonstrates the validity of the method. The pre-well and real-time 3D models can also be utilized to generate quantitative volumetrics calculations while drilling. The workflows provide an information rich environment for operational decision making leading to better wells.

Abstract
The current explosive limit chart using in the oil and gas industry published with unclear condition of safety factor and consequence of overexposing temperature and time, resulting in many published papers disclose the possibility of expanding the safe-operating envelope of HMX. HMX is preferable because it typically provides deeper penetration than HNS but less stability at high temperature. Therefore, this study aims to maximize use of HMX for hollow gun perforation in typical environment in the GOT.
The explosive temperature limit depends on two parameters, exposure time and temperature. The maximize use of HMX could achieve by, either ways, reducing the exposure time or extending the temperature limit line. Firstly, the operating time optimization is doable by using statistic record of the depth perforated by HNS and practical running speed together with a 20% safety margin. Secondly, expanding the temperature limit of HMX is a precise task because the HMX once exceeding the stability temperature, the perforating performance losses and explosion hazard arises due to thermal decomposition. However, this could be creditable by integrating the published explosive testing results over the current operating-envelope and applying a safety margin.
The represented operating time, counting from running in hole to tool on surface, for perforation with E-line unit in the high-temperature environment could reduce by an hour. This operating time allows the temperature limit of HMX increasing by only 7 F, which considering as insignificant. The integrating result of three published paper indicated no explosive deflagration happens if the temperature is below the "Fiasco line" – introduced by a company, however, the operating time longer than 200 hours is not incorporated. By applying safety margin, the new operating envelope of HMX in the hollow carrier proposes between the typical and the Fiasco line. Combing time optimization and the new line, the HMX temperature limit extends from 375 F to 394 F for 2.2 operating hours. This new criterion has been applied successfully since 2018; 325 m of HMX achieved perforation condition without an indication of misfire or catastrophic self-detonation, resulting in reduce 50% of HNS consumption. In conclusion, the new temperature cutoff is valid for maximizing the use of HMX with a reasonable safety margin.

Abstract
The operator relentlessly thrives for the minimum well construction cost. Continuous improvement and Innovative approach are the major drives for developing the marginal gas field, Myanmar offshore. Whereas, routine and consistent operations may mask up the operator and leave out many rooms for improvement from operation excellence during the development phase of the project life cycle.
PTTEPI successfully started up the second development campaign, Myanmar offshore in early 2016. Since then the team has brought up many ideas to continuously improve the operation and achieve milestones for both safety and performance. This paper will share the best in class for well construction of Myanmar offshore on well design, drilling engineering, rig selection, offline utilization, drilling and sand control practices and fit for purpose procedures. The performance is significantly improved on both drilling and sand control operation which results in total days per well reduction over 50% and 80% for drilling operation and sand control operation respectively.
Total days per well for drilling performance on the last platform in 2019 is reduced to 4 days per well compared to 9 days per well when the first development platform was drilled in 2013. Sand Control performance is improved further. Total days per well for Sand Control performance on the last platform in 2019 is reduced to 3.5 days per well (dual-zone completion) compared to 18 days per well when the first development platform was completed in 2013.
Recommended practices and well designs are shared as a case study of drilling and sand control operation for Myanmar offshore development. This can be a guideline for another operator to develop oil and gas field offshore Myanmar.
