Abstract
O&G operators seek to reduce CAPEX by reducing unit development costs. In drilling operations this is achieved by reducing flat time and bit-on-bottom time. For the last five years, we have leveraged data generated by drilling operations and machine learning advancements in drilling operations. This work is focused on field test results using a real-time global Rate of Penetration (ROP) optimization solution, reducing lost time from sub-optimal ROPs. These tests were conducted on offshore drilling operations in West Africa and Malaysia, where live recommendations provided by the optimization software were implemented by the rig crews in order to test real-world efficacy for improving ROP. The test wells included near-vertical and highly deviated sections, as well as various formations, including claystones, sandstones, limestones and siltstones. The optimization system consisted of a model for estimating ROP, and an optimizer algorithm for generating drilling parameter values that maximize expected ROP, subject to constraints. The ROP estimation model was a deep neural network, using only surface parameters as inputs, and designed to maximize generalizability to new wells. The model was used out-of-the-box, with no specific retraining for the field testing.
During field-tests, increased average ROP was observed after following recommendations provided by the optimizer. Compared to offset wells, higher average ROP values were recorded. Furthermore, drilling was completed ahead of plan in both cases. In the Malaysian test well, following the software's advice yielded an increase in ROP from 10.4 to 31 m/h over a 136 m drilling interval. In the West Africa well, total depth was reached ∼24 days ahead of plan, and ∼2.4 days ahead of the expected technical limit. Importantly, the optimization system provided value in operations where auto-driller technologies were used. This work showcases field-test results and lessons learnt from using machine learning to optimize ROP in drilling operations. The final plug-and-play model improves cycle efficiency by eliminating model training before each well and allows instantaneous, real-time intervention. This deployable model is suitable to be utilized anytime, anywhere, with retraining being optional. As a result, minimizing the invisible lost time from sub-optimal ROP and reducing costs associated with on-bottom drilling for any well complexity and in any location is now part of the standard real-time operation solutions. This deployment of technology shows how further optimization of drilling time and reduction in well cost is achievable through utilization of real time data and machine learning.

Abstract
Wellbore cleaning is a vital link between drilling operations and well completion to secure the massive time and money invested to drill the hole intervals by removing drilling fluids residues, pipe dope, and other debris from the wellbore. The well production can be sustained in the long-term by properly accomplishing this step, promoting technical and operational efficiencies. This paper presents an effective customized treatment design and successful execution of a wellbore cleaning case study.
The Wellbore cleaning process is a combination of both mechanical and chemical means, a cleanout string of scraper, brush, magnets, and pill train of surfactants, and solvents are expected to retrieve debris and displace mud residues leaving the wellbore water wet, whose efficiencies can be judged through return fluids Nephelometric Turbidity Unit (NTU) and Total Suspended Solids (TSS). Since different wells vary in geometry, depths, and mud components, a custom design for the wellbore cleaning process is mandatory to guarantee satisfying treatment outputs, the design includes cleanout string parts and spacing, besides solvents and surfactants pills train additives, and volume.
Extensive lab testing was performed to customize the proper wellbore cleaning design to remove inverted emulsion fluids (IEF) residues from casing and tubing in the studied challenge gas well. The casing pickling was executed with 150 barrels (bbl) of solvent and surfactant chemical cleaning Spacers containing 630 gallons (gal) of locally manufactured solvent and 378 gal of locally manufactured surfactant displacing the wellbore water with clean water.
The water returns NTU and TSS of 47 and 0.03 % Solids respectively were achieved at 179 bbl after the high viscosity tail spacer of the casing pickling. The Cleanout Bottom Hole Assembly (BHA) was subsequently pulled out of the hole free from IEF residues and water wet, demonstrating the good cleaning performance of the locally formulated Chemistries. Similarly, the Tubing Pickling was executed with 54 bbl of Chemical cleaning spacer containing 990 gal of solvent. The water returns NTU and TSS of 38 and 0.02 % Solids respectively were achieved at 168 bbl after the high viscosity tail Spacer of the tubing pickling. In a conclusion, the low NTU and TSS values confirmed the effective wellbore cleaning design and treatment.
In this paper, we will be presenting a custom treatment design and successful execution of a wellbore cleaning case study from a chemical perspective, using 100% locally developed chemistries, that are environmentally friendly and readily available in-country, adding the value of lead time and optimized cost to drilling operations, where selected treatments could achieve targeted return fluids NTU and TSS within competitive displacement volume for both casing and tubing.

Abstract
Potassium chloride (KCl) is typically used in the formulation of cement spacers to inhibit the shales from swelling and dispersion. It serves as a shale inhibitor during cementing operations to ensure good wellbore integrity. To obtain optimum inhibition, a high concentration of KCl might be required. A massive amount of potassium chloride will lead to a negative impact on the environment, cement slurry setting time, and wireline logging methods. This work aims to design and synthesize a novel inhibited cement system with an improved shale inhibition performance and wellbore integrity without harming the ecosystem.
A spacer and cement formulation utilizing a novel mixture of different high molecular weight polyamines have been prepared successfully and compared against conventional formulations. Our study includes dispersion testing using representative shale samples and spacer compatibility with water-based drilling fluids and cement. The compatibility investigation included rheology testing, thickening time testing, compressive strength measurements, and free water tests.
The study shows that KCl concentration should be monitored carefully to avoid cement immature settings. KCl salt also resulted in improper wellbore integrity due to its low performance in shale inhibition compared to amines. Amines did not result in retardation nor acceleration of cement setting. Representative shale dispersion with cement filtrates and spacers show a high dispersion recovery factor of 96.5%, with the novel polyamine additive compared to 82% with potassium chloride.
We illustrated detailed experimental and field applications of a novel mixture of different high molecular-weight polyamines. Contrary to conventional KCl, the new formulation resulted in improved shale inhibition and enhanced wellbore integrity. The value of this study was further validated by the successful execution of cementing a casing installed in a water-sensitive shale formation.
Degradable Plug Technology Holds Pressure for 32 Hours and Eliminates Risk of Intervention in Tight Gas Reservoirs

Abstract
Plug and perf technique is a common method to unlock the potential of tight gas formations. The conventional method is to set millable plugs to establish zonal isolation between target stages. A new degradable frac plug has been introduced for high pressure and high temperature applications in sandstone formations plug and perf hydraulic fracturing operations. The development and deployment of the degradable frac plugs that are capable of holding 32 hours of targeted pressure to optimize the cost and time of the conventional well intervention in tight gas reservoirs in Saudi Arabia is presented in this paper.
In conventional plug and perf stimulation operations each plug is milled out via coiled tubing. This process increases operational risk and cost associated with multiple downhole trips. Another challenge is wellbore accessibility post stimulation operations. Without changing the fracturing design, two degradable plugs in a three-stage well were deployed. Downhole conditions presented significant challenges including high temperatures of 285 F and pressures. By using a degradable plug, post-frac interventions can be eliminated as the entire plug will degrade in downhole conditions. This would allow the well to be brought online faster than a conventional method would allow.
Operational challenges have been experienced during the first deployment of the plug. The plug has successfully held pressure for 32 hours while being exposed to wellbore fluids, which is one of the longest times achieved for a degradable frac plug. One of the main reasons of such success is that the plug is composed of high-grade material. While the plug maintained its integrity for 32 hours in high pressure, it degraded to fine particles post frac operations. Furthermore, the plug was trial tested without affecting the stimulation goals or the overall operation for such well. On this trial test, the plug has shown the ability to eliminate HPCT trips and the associated risks of HPCT intervention. To confirm dissolution of the plugs, an assessment CT run was performed and confirmed shallower plug was not dissolved after 32 hours while the deeper plug already dissolved.
With the spread of plug and perf technology on a global level and the increase of horizontal multistage stimulation methods, it is important to capitalize on fit for purpose technologies versus a one-size fits all approach. To address the challenges associated with longer laterals and increasing stage counts, degradable plug technology can be used to improve well economics and reduce associated risks. The elimination of mechanical intervention is the next breakthrough in efficiency gains to increase laterals and achieve higher stage counts.

Abstract
Identification of lithology from drilling cuttings is a key step for reservoir characterization. At present, the traditional method is to collect and analyze the cuttings by manual interpretation, which is subjective and time-consuming. In order to improve the accuracy, timeliness, and automation of identification of cuttings lithology, this paper completed lithology identification and classification through batch iterative training based on Resnet-34 network. Automated rock type identification from cuttings images captured by a given camera is the goal of this work. The main challenge in cuttings recognition is the similarity of color and grain size in two or different cuttings. Another important factor is that the light source of the camera. In order to capture the images of cuttings more comprehensively for identification, a single light source with 8 channels (ultraviolet, blue, green, yellow, red, infrared, far infrared, and white light) was used to irradiate the cuttings during the imaging process, and the imaging information of cuttings in the full spectral segment can be obtained as the input of the deep learning network. In order to solve the overfitting problem caused by data duplication under different light sources, the input images are first preprocessed by brightness equalization and random cropping, so that each grayscale image can have the same brightness and do not have too much repetition under different light sources. In terms of the efficiency and accuracy, Resnet-34 is selected as the model framework of cuttings recognition and classification. The overall accuracy of the model is increased to 98.6% combined with the actual hardware support in the field, which promotes the more efficient identification of logging cuttings and provides a theoretical basis for improving the online logging of logging in the field.

The idea of using the rigless equipment came into play, prompting a trail in business year 2022. The main objective of this newly developed initiative was to look into opportunities where it could be made use of the light rigless intervention which involves the use of light rigless intervention, which involves the use of specialized equipment and techniques to perform the planned well services rather than the use of a conventional rig or/and heavy equipment. Based on that, an exercise conducted in conjunction with the drilling operation teams was carried out, to review and check the drilling workover schedule for potential wells. The scope of work was defined, cases were studied, and the required resources were prepared. The rigless intervention campaign scope has been completed within planned schedule and budget in addition to these types of light interventions enable use fewer equipment footprint, offer improved safety compared to traditional methods by control risks to workers and use of smaller crew members, and leave a remarkable reduction in carbon emission footprint on each well location which in turn makes a positive differences when it compared with conventional rig-based operations.

Published: May 2023

Abstract
The deep shale gas reservoir are high formation temperature and pore pressure in Sichuan Basin. Due to the unclear geomechanical characteristics of the reservoir, a large number of accidents occurred during the drilling operation. At the same time, the wellbore instability and frequent adjustment trajectory cause long drilling cycle, low drilling efficiency, and high drilling operation cost. To solve the above problems, the drilling mud weight is optimized based on the three-dimensional geomechanical research and by establishing the pore pressure, collapse pressure and fracture pressure (leakage pressure) models. The key technology of reducing drilling mud weight are used to significantly reduce the drilling mud loss. Field application shows that the mud weight is reduced from 2.15 g/cm3 to 1.87 g/cm3, the average ROP increased by 44.1% from 8.4 m/h to 12.1 m/h, the average drilling operation cycle decreased by 40.7% from 54.2 days to 32.1 days, and the drilling performance and efficiency are significantly improved. The fine 3D geomechanical modeling technology has great promotion and reference significance for the performance and efficiency improvement of the deep shale gas horizontal well drilling operation in China.

Published: May 2023

Abstract
Mud-induced damage is highly pronounced in horizontal wells due to the longer period of exposure to drilling mud and low draw-down pressure. Enzyme-based cleanup fluids are preferred for filtercake removal applications, especially in horizontal wells due to their several advantages compared to conventional cleanup fluids. The advantages include low reactivity, less corrosivity, more environmentally safe, polymer-specific enzyme breakers, and ultimately homogenous filtercake removal coverage. Most enzyme-based cleanup fluids are limited to low temperatures.
In this study, extensive lab work was conducted to evaluate an enzyme-based/in-situ generated organic acid cleanup fluid for a water-based mud at a temperature of 250°F. The experimental work included coreflood experiments, HT/HP filter press, and see-through cell. Analytical techniques, including ICP, XRD, EDXRF, IFT, and iodine tests, were used to assess the interaction of the cleanup fluid with filtercake components.
The results showed that the enzyme/in-situ organic acid generated cleanup system was effective at degrading filtercake for a water-based mu field sample, which was reflected in the obtained return permeability of nearly 83%. Iodine tests confirmed that the enzyme was able to degrade the starch present in the filtercake. The surface tension of fluid is generated due to the interaction of the enzyme-based breaker with the filtercake at 250°F and for 48 hours was 31.11 dynes/cm at 22°C, which indicates that this system can help to prevent water blockage problems, especially for gas tight formation. This paper will discuss in detail all experimental results and findings.

Abstract
The inclusion of expansive agents in cement slurries has been proposed as a method to avoid shrinkage and reducing the probability of generating a microannulus at the interface between cement sheath and casing or formation wall. This work focuses on the effect that an expansive agent has on the mechanical and microstructural properties of cement paste when compared to conventional class G cement, aiming to identify any potential detrimental effects that might be induced by its inclusion.
Two cement slurries were evaluated: a class G cement used as a Reference and a second with the addition of 3 % of expansive agent. The slurries were fully characterized and cured under atmospheric or pressurized conditions for a duration of up to fifteen days. Cured cement specimens were analyzed to determine the influence of the expansive agent on early age mechanical properties development and microstructural properties. Development of mechanical behavior was measured using an ultrasonic cement analyzer (UCA). Microstructural properties were determined by scanning electron microscopy (SEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA).
Annular ring test at 27 °C for 15 days showed an expansion of 0.021 % in circumferential change for the expanded slurry, while the class G cement used as Reference achieved a value of 0.016 %. Both results are mainly due to silica effect. The same test performed at 70 °C for 7 days showed an expansion of 0.038 % in circumferential change for expanded slurry, which represents the effect of the additive dissolution and hydration, and a shrinkage of 0.012 % in circumferential change for Reference. UCA showed the tendency of acceleration of hydration kinetics caused by the expansion additive. An increase in compressive strength for expanded slurry can be related to its hydration and formation of a denser microstructure. SEM showed a uniform dispersion of magnesium in the cement matrix with some Mg(OH)2 crystals formed. Hydration products were also seen with a predominance of ettringite for samples cured at atmospheric pressure. XRD showed characteristic peaks of hydration products for all slurries, with an increased intensity for expanded slurries. TGA showed similar curves for all slurries, with the presence of thermal decomposition of magnesium hydroxide for expanded slurries. It was concluded that the presence of expansion additive in the cement slurry in an amount of 3 % was not found to be detrimental to the mechanical and microstructural properties.
Literature has a lack of connection between microstructural analysis with mechanical properties of slurries developed with expanded additive in downhole conditions. This paper intends to fill this gap detailing the high potential of this additive through an in depth characterization and comparison with a Reference slurry concerning the mechanical and mineralogical properties.
