The IADC and SPE are committed to delivering a balanced agenda around diversity and inclusion, and to support member companies as they strive to address the gap in the oil and gas sector. This session will explore the challenges facing the industry and how they can be addressed. This initiative aims to build on the efforts already being undertaken at individual company levels to attract, develop and retain female staff — especially in technical and senior management roles — and to remove barriers that may currently hinder or discourage women from rising through the ranks into leadership roles. The aim is to address the factors contributing to the gender gap and to advantage all companies, their owners and shareholders through the incremental performance and value that parity will generate. This is good for our people, good for our stakeholders, and good for our business.
To maximize reservoir contact during well placement in layered carbonate reservoirs, reentry and newly drilled wells often target a specific layer. In this case, traditional well placement techniques of horizontal wells using a reactive or semi-proactive approach result in repeated exits of the reservoir target into the cap rock or potentially dip out of the target zone. This environment may result in losing reservoir footage, a lower net-to-gross, prolonged drilling time and wellbore challenges. All these items increase wellbore delivery time and cost.
Existing logging-while-drilling (LWD) technology for well placement and formation evaluation has been extensively used in different environments. For example, borehole resistivity image logs to acquire real-time formation dips and provide at-bit resistivity measurements to help identify local features that may correlate with the structural dip. However, in many cases, especially for wells drilled close to the flank, carbonate layers are not as "flat" as seen in the seismic sections.
Conventional deep-azimuthal resistivity technology was designed and introduced mainly for a clastics environment, where a clear resistivity contrast between shale and sand zones exists. The technology can help in mapping the target sand beyond the well trajectory. This is not the case with carbonate reservoirs, where the contrast is not obvious and the signal saturates due to proximity to anhydrite layers, masking the different reservoir layer boundaries. To overcome this challenge and enable bed boundary mapping tools to focus on a shallow depth of investigation, a new resistivity inversion called multi-component while drilling (MCWD) is introduced.
The MCWD inversion technique utilizes the deep-azimuthal resistivity data to map the thickness and boundaries of different resistivity layers focused within the required depth of investigation. Consequently, conventional deep-azimuthal resistivity technology is adapted for proactive geosteering in relatively conductive medium by mapping the high-resistivity layer boundary (anhydrite) and the low-resistivity contrast base layer to maintain the wellbore optimally in the target zone.
Results of this new inversion are demonstrated to show the combination of deep-azimuthal resistivity technology along with MCWD inversion to successfully place horizontal laterals within carbonate sublayer. Another added value is the mapped structural features that can help to improve the structure model and assist with real-time geosteering decisions. In addition, qualitative petrophysical evaluation could help to map the water front and the oil/water contact in some cases.
The deployment of this technology has helped to improve drastically the Net-to-Gross (N/G) in these challenging environments, and more applications are currently being studied to develop further the use of the real-time azimuthal directional resistivity logging data.
The IADC and SPE are committed to delivering a balanced agenda around Diversity and Inclusion, to support member companies as they strive to address the gap in the Oil & Gas Sector. In 2019 the SPE/IADC International Drilling Conference and Exhibition in The Hague will host a session that allows delegates to explore the challenges facing the industry and hear firsthand, how it can be addressed. This initiative aims to build on the efforts already being undertaken at individual company levels to attract, develop and retain female staff - especially in technical and senior management roles, and to remove barriers that may currently hinder or discourage women from rising through the ranks into leadership roles. The aim is to address the factors contributing to the gender gap and to advantage all companies, their owners and shareholders through the incremental performance and value that parity will generate. This is good for our people, good for our stakeholders, and good for our business. Whilst in 2017 the session focused on subjects arising from DAVOS 2016 namely Leadership, Aspiration, goal setting, STEM, recruitment and retention, corporate culture and work life balance, the panel now feel it is time to move the conversation forward with some hard-hitting topics that affect the lives of many. Make sure you join us for this special session in The Hague.
Easy oil is no longer low hanging fruit for oil and gas operators, and drilling targets are becoming increasingly ambitious, which results in escalation of the well trajectory complexity. This accordingly spirals the well and completion costs. To overcome this situation, technology must play a role to reduce cost, increase efficiency and ensure safety at all times. Conveyance is the key for any data acquisition and well completion activities. Historically, conveyance methods for data acquisition and perforation in highly deviated or horizontal wells required drill pipe or coiled-tubing methods. These methods are time consuming, labor intensive, require a larger equipment footprint, with possible HSE risks involved. Mubadala Petroleum in Thailand has seen a significant increase in horizontal and high deviated wells over the past few years. The wireline tractor technology has been used for the first time in Mubadala Petroleum's Thailand operations during the drilling, initial completion and workover intervention operations, and it has been a game changer for Mubadala Petroleum in Thailand in terms of reducing rig time, well cost, and most importantly minimizing the HSE risks.
Over the past few decades, the oil and gas industry has developed the technique of drilling horizontally through the reservoir to maximize the surface contact area of the reservoir, to gain higher recovery and production. However, one downside from this technique is that it has become challenging and costly to perforate or to obtain measurements in this horizontal environment, as gravity will no longer support the wireline tools to reach to the bottom of the well. Wireline Tractor technology has played an important role to overcome this challenge. It reduces time, cost and will improve data quality as well as increase wellbore coverage. The wireline tractor functions with an electric over hydraulic power relationship, using its drive/wheel sections to push the passenger tool downhole as the cable is spooled off the unit allowing the tool to reach the end of horizontal or deviated wells without deploying drill pipe or coiled tubing conveyance methods. With this principle, any job that is typically run on electric wireline in a vertical well can be efficiently done in a horizontal or deviated well using wireline tractor.
Material presented in the paper will be from actual operations, examples being tractor conveyed wireline logging tool and 4.5in Outer Diameter (OD) 90 ft heavy long perforation gun in single tractor operations. It will also display the operational efficiencies increases and risk reduction being obtained.
The Jasmine Field sandstone reservoir described in the paper is highly compartmentalized, has a sand thickness of about 30-40ft, reservoir pressure is supported by a strong aquifer, and most wells have high productivity. However, in the particular fault block of interest, a gas cap is present, which is normally not present in other fault blocks. This reduces the oil sand thickness to about 20 ft, with a big gas cap above and water below. To efficiently produce the oil rim in this area, a horizontal well was required, with an electrical submersible pumps (ESP) to aid lift. Since ESPs don't typically handle gas very well, the challenge was to ensure the well is economic by preventing premature gas breakthrough, and hence increase oil recovery.
The Autonomous Inflow Control Device (AICD) is an active flow control device that delivers a variable flow restriction in response to the properties (viscosity) of the fluid flowing through it. Water or gas flowing through the device is restricted more than oil.When used in a horizontal well, segmented into multiple compartments, this device prevents excessive production of unwanted fluids after breakthrough occurs in one or more compartments. The JS-06 well was drilled with almost 2000 ft horizontal length within the original thin oil column, with gas on top and water below. AICD flow loop testing, performance modelling, candidate selection, and completion design for this well was focused on gas production control, given that gas production was the main concern.
Post implementation and production, gas production has been controlled very well compared to the base case conventional completion. The gas oil ratio (GOR) observed from nearby wells was within the normal production range, which has allowed more oil to be produced from the JS-06 well. The production results observed were consistent with modelling and laboratory flow testing, thereby increasing confidence in the methods employed in designing the AICD completion for the well and in AICD modelling and candidate selection.
The successful implementation of AICD in this well has opened up another similar opportunity, which are currently being evaluated for the same application
Asia is the largest and the most populous continent in the world covering an area of 44,579,000 sq. Its 4.5 billion people form roughly 60% of the world's population. To understand the intricacies of this vast and diverse continent, it is a common practice to categorize the constituting countries as per the subject--economic development--under discussion. One such categorization is "Tiger Economies." It is the nickname given to the economies of Southeast Asia. The tigers are South Korea, Taiwan, Hong Kong, and Singapore.

There is no longer a requirement to run wireline Triple Combo logs in deep, high temperature wells. A joint development project has successfully delivered the world's first high-temperature M/LWD Triple Combo suite rated for 200°C [392°F]. Results to date are compared with previous performance in the Gulf of Thailand (GoT).
The new suite required a ground-up redesign of printed circuit board (PCB) electronics in order to meet the temperature qualification criteria of 200 hours at 200°C [392°F], with a survivability of 210°C [410°F] for four hours. The suite's sensors were developed in two phases, each with four milestones, over a period of 36 months. Initial rigorous thermal qualification was followed by harsh thermal vibration qualification testing routines. Several PCB redesigns were required in order to finally pass this testing. Ultimately, five prototype triple combo suites of tools were delivered to Thailand, on time and on budget, for in-situ field testing.
M/LWD Triple Combo field trials commenced offshore in the GOT, in fields exhibiting some of the global industry's most demanding drilling environments with respect to high rates of penetration [and accompanying punishing levels of vibration], extreme temperatures and significant well complexity. Compared to adjacent platforms with similar wells in the most challenging field, the new suite, together with other drilling efficiency measures, played a pivotal role in helping to reduce average days per well over 50% a considerable improvement. To date, more than 475,000 ft [145,000 m] have now been drilled in 71 GoT wells using this Triple Combo M/LWD technology. Furthermore, the new high-temperature Triple Combo M/LWD tools have been one of several key contributing factors in establishing two notable drilling records: drilling the GoT's longest well at 17,559 ft [5,532 m] and the longest single-bit run in the production section at 8,952 ft [2,729 m], without any failures at a maximum temperature of 199°C [391°F]. The suite provides additional benefits such as the provision of real-time annular pressure while drilling.
With this feature, engineers can closely monitor the equivalent circulating density (ECD) an important parameter for avoiding kicks and losses at up to 200°C [392°F].
The proven step change in drilling efficiency arising from this joint development can be attributed to the elimination of temperature mitigation measures and Triple Combo wireline logging, the problems associated with acquiring the wireline data, and an overall improvement in drilling practices.
