Abstract The CO2 capture technology is well understood in the oil and gas industry. However, to unlock the Hydrocarbon from an ultra-high CO2 offshore field (more than 70% mol), special attention is needed to capture CO2 for a field development to be economically attractive. Therefore, the current technology inventory needs to be studied to achieve project goals and at the same time achieving Carbon Capture and Storage (CCS) requirements. A hybrid of multiple carbon capture technology will help to improve the hydrocarbon (HC) loss, reduce both operational and capital cost and minimize overall auto consumption. The hybrid of cryogenic distillation (CryoD), membrane and supersonic gas separation (SGS) was studied to explore its feasibility. To enable ease of CO2 transport and handling, CO2 is preferred to be in liquid form. In order to achieve this, CryoD technology is the preferred solution for bulk removal. CryoD is also able to cater to the feed gas fluctuation and becomes a robust candidate for high variance feedstock. However, being dependant on sub zero working temperatures, the system will require larger equipment footprint and tonnage. The focus of the study is to evaluate the sensitivity impact of an operating condition on the Hybrid configuration of CryoD + membrane (CM) and CryoD + SGS (CS. Areas of focus will be equipment tonnage and footprint, power consumption and eventually cost (CAPEX & OPEX). The monetization of ultra-high CO2 gas field is then made feasible by using hybrid Acid Gas Removal Unit (AGRU) to meet sales gas specification. The CryoD + membrane technology is the preferred solution for offshore system.

Abstract Hydraulic fracturing is a widespread well stimulation treatment in the oil and gas industry. It is particularly prevalent in shale gas fields, where virtually all production can be attributed to the practice of fracturing. It is also used in the context of tight oil and gas reservoirs, for example in deep-water scenarios where the cost of drilling and completion is very high; well productivity, which is dictated by hydraulic fractures, is vital. The correct modeling in reservoir simulation can be critical in such settings because hydraulic fracturing can dramatically change the flow dynamics of a reservoir. What presents a challenge in flow simulation due to hydraulic fractures is that they introduce effects that operate on a different length and time scale than the usual dynamics of a reservoir. Capturing these effects and utilizing them to advantage can be critical for any operator in context of a field development plan for any unconventional or tight field. This paper focuses on a study that was undertaken to compare different methods of simulating hydraulic fractures to formulate a field development plan for a tight gas field. To maintaing the confidentiality of data and to showcase only the technical aspect of the workflow, we will refer to the asset as Field A in subsequent sections of this paper. Field A is a low permeability (0.01md-0.1md), tight (8% to 12% porosity) gas-condensate (API ~51deg and CGR~65 stb/mmscf) reservoir at ~3000m depth. Being structurally complex, it has a large number of erosional features and pinch-outs. The study involved comparing analytical fracture modeling, explicit modeling using local grid refinements, tartan gridding, pseudo-well connection approach and full-field unconventional fracture modeling. The result of the study was to use, for the first time for Field A, a system of generating pseudo well connections to simulate hydraulic fractures. The approach was found to be efficient both terms of replicating field data for a 10 year period while drastically reducing simulation runtime for the subsequent 10 year-period too. It helped the subsurface team to test multiple scenarios in a limited time-frame leading to improved project management.

The oil and gas sector is an important factor in sustainable development, so it is considered necessary to make serious changes in conducting economic analysis on the oil and gas business. Oil and gas industry activities consist of upstream activities, and downstream activities. Activities in these upstream and downstream operations have high risk, high costs and high technology, so the company continuously tries to reduce the importance of the adverse impact of these risks on the work environment and people. Thus, evaluating the factors that affect sustainable production in this sector becomes a necessity. In this research will be evaluated the economy of the oil and gas field using methods of economic indicators, among others; NPV, POT, ROR, where these factors are estimated in order to be able to estimate the prospects of the oil and gas field so that the decision that the field development project can be implemented or cannot be taken immediately.

The non-corrosive, electrically resistive fiberglass casing materials may improve the economics of oil and gas field projects. At moderate temperatures (<120 °C), fiberglass casing is superior to carbon steel casing in applications that involve wet CO2 injection and/or production, such as carbon capture and storage, and CO2-based enhanced oil recovery (EOR) methods. Without a perfect protective cement shell, carbon steel casing in contact with a concentrated formation brine corrodes and the fiberglass casing is superior again. Fiberglass casing enables electromagnetic logging for exploration and reservoir monitoring, but it requires the development of new logging methods. Here we present a technique for the detection of integrity of magnetic cement behind resistive fiberglass casing. We demonstrate that an optimized induction logging tool can detect small changes in the magnetic permeability of cement through a non-conductive casing in a vertical (or horizontal) well. We determine both the integrity and solidification state of the cement-filled annulus behind the casing. Changes in magnetic permeability influence mostly the real part of the vertical component of the magnetic field. The signal amplitude is more sensitive to a change in the magnetic properties of the cement, rather than the signal phase. Our simulations showed that optimum separation between the transmitter and receiver coils ranged from 0.25 to 0.6 m, and the most suitable magnetic field frequencies varied from 0.1 to 10 kHz. A high-frequency induction probe operating at 200 MHz can measure the degree of solidification of cement. The proposed method can detect borehole cracks filled with cement, incomplete lift of cement, casing eccentricity, and other borehole inhomogeneities.

Uncertainty Model

Abstract We are all aware that our future is uncertain. Although some aspects can be predicted with more certainty and others with less, essentially everything is uncertain. Uncertainty exists because of lack of data, lack of resources, and lack of understanding. We cannot measure everything, so there are always unknowns. Even measurements include measurement errors. Also, we do not always have enough resources to analyze the data obtained. In addition, we do not have a full understanding of how the world, or the universe, works (Park 2011). Every day we find ourselves in situations where we must make many decisions, big or small. We tend to make the decisions based on a prediction, despite knowing that it is uncertain. For instance, imagine how many decisions are made by people every day based on the probability of it raining tomorrow (i.e., based on the weather forecast). To have a good basis for making a decision, it is of critical importance to correctly model the uncertainty in the forecast. In the oil and gas industry, uncertainties are large and complex. Oil and gas fields have been developed and operated despite tremendous uncertainty in a variety of areas, including undiscovered media and unpredictable fluid in the subsurface, wells, unexpected facility and equipment costs, and economic, political, international, environmental, and many other risks. Another important aspect of uncertainty modeling is the feasibility of verifying the uncertainty model with the actual results. For example, in the weather forecast it was announced that the probability of raining the next day was 20%. And the next day it rained. Do we say the forecast was wrong? Can we say the forecast was right? In order to make sure the uncertainty model is correct; we should strictly verify all the assumptions and follow the mathematically, statistically, proven-to-be-correct methodology to model the uncertainty (Caers et al. 2010; Caers 2011). In this paper, we show an effective, rigorous method of modeling uncertainty in the expected performance of potential field development scenarios in the oil and gas field development planning given uncertainties in various domains from subsurface to economics. The application of this method is enabled by using technology as described in a later section.

And Storage

In 1972, carbon dioxide (CO2) began to be captured from natural gas processing plants in West Texas and transported via pipeline for enhanced oil recovery (EOR) to oil fields also in Texas. This marked the beginning of carbon capture and storage (CCS) using anthropogenic CO2. Today, there are 22 such large-scale CCS facilities in operation or under construction around the world. These 22 facilities span a wide range of capture technologies and source feedstock as well as a variety of geologic formations and terrains. Seventeen of the facilities capture CO2 primarily for EOR. However, there are also several significant-scale CCS projects using dedicated geological storage options. This paper presents a collation and summary of these projects. Moving forward, if international climate targets and aspirations are to be achieved, CCS will increasingly need to be applied to all high emission industries. In addition to climate change objectives, the fundamentals of energy demand and fossil fuel supply strongly suggests that CCS deployment will need to be rapid and global. The oil and gas sector would be expected to be part of this deployment. Indeed, the oil and gas industry has led the deployment of CCS and this paper explores the future of CCS in this industry.
