Abstract
This paper will detail the engineering strategies utilized from design and planning stage up to and beyond the field execution stage which resulted in drilling the fastest well in a shallow water field, delivering superior drilling performance and successfully targeting the Upper Miocene (tertiary) reservoir in Mexico.
From the 9 wells drilled in this field, the fastest well "Y"-200 was drilled with an average well construction index of 179 m/day when compared to the field average of 54.2 m/day. This shallow water field manifests several specific challenges which include tough drilling conditions, fluid property and hydraulic management, logging constraints and critical selection of casing setting depths.
In order to enhance the drilling performance results to lower costs and improve production timelines, the project team performed a deep-dive into the well challenges and engaged with multi disciplinary teams and service providers to brainstorm different design improvements and operational practices. By doing so, the performance accelerates the 6000 to 9000 bbls of initial production estimated per well.
The application of these creative engineering ideas proves that change, when applied correctly can really create lasting and proven improvements in drilling performance.

Abstract
X-Field is a mature offshore field located in the Sabah Basin, Malaysia. Two horizontal oil producers and one horizontal water injector was planned as part of the recent infill drilling campaign. As fields continue to mature, redevelopment projects often face both economical and technological challenges. Part of the redevelopment plan included the optimization of production and minimization of the residual/remaining attic oil in the reservoir.
The horizontal well placement approach combined with drilling engineering concepts was synergized to handle the subsurface and drilling challenges. There are many key subsurface uncertainties when drilling horizontal wells, including but not limited to discontinuous sand bodies, lateral variations in sand thicknesses, multiple layering or sand/shale pockets, rapid structural changes, and fluid contact variation.
In the planning stage, a systematic drilling engineering approach in managing drilling risks including complex anti-collision analysis contributed to successful drilling performance driven by "on-target" well placement execution. Selection of well placement technologies such as high definition multilayer-boundary mapping technology and wellbore imaging tool had enabled proactive geosteering to optimize the reservoir targets. This paper demonstrates the synergy of the drilling engineering and well placement technology selection, which was proven as a fit-for-purpose solution to deliver success to this horizontal well campaign in maximizing the production and injection potential.

Abstract
Sand production is one of the operators’ intimidating challenges as the cascading effects can cause significant damages to the surface equipment and often lead to costly clean-up effort. Its effects are further amplified in gas wells with higher gas velocities lead to more detrimental effects on the facilities. Consequently, the facilities will deteriorate, leading to uncontrolled hydrocarbon release which compromise the operation safety considerably. Hence, sand detection devices such as acoustic sensors are extremely crucial to detect sand production as early as possible prior to any undesirable damage. This paper highlights the selection reasoning and advantages of permanent acoustic sensors as well as the method in maximizing the data value through integration with digital field monitoring.
Various sand monitoring equipment are available in the industry and its selection is mainly driven by operators’ purpose with cost-benefit analysis. The multi-disciplinary team collaboratively decided on a holistic approach of utilizing the permanent acoustic sensors to its maximum potential. Integration of permanent acoustic sensors with digital field monitoring further improves the investment return as the sensors can provide real-time sand production data. Effective real time sand monitoring can be performed by both offshore and onshore crews where immediate countermeasure can be deployed if abnormal readings detected.
When handling sand prone wells, proactive measures have been proven to be more effective if compared to reactive measures. Each well production potential can be maximized by installing sand sensors to ensure safe operating envelope without sand production as well as to trigger alarm if sand detected. The key to unlocking the potential is to ensure data is effectively transmitted to the command center and to the office via our digital field system. The operators are also trained on the next course of action such as beaning down the wells to safe operational envelope in case of sand breakthrough. The value of the acoustic sensors outweighs the total cost involved as real-time sand monitoring system helps to safeguard surface facility integrity considerably.
An Impedance Sensor of Water Cut with Three Electrodes and Relative Analysis on Experiment Results

Abstract
Single-layer water cut measurement is of great significance for identifying and shutting off the unwanted water, analyzing oil remained and optimizing production. Currently, however, only the water cut of multilayer mixture can be measured by testing samples taken from wellhead, a way which is widely used in oilfields. That of single-layer fluid cannot be determined yet
To address the problem, this paper puts forward a new impedance sensor that offers long-term online monitoring of single-layer water cut. This sensor is based on the different electrical conductivity of oil and water. It has two layers. The inner one contains three electrodes - two at both sides sending sinusoidal excitation signals and one at the middle receiving signals that have been attenuated by the water-oil medium. With the Maxwell's model of oil-water mixed fluid, the receiver then can measure the water cut online. The outer layer of the sensor is made of PEEK, an insulative protection. In front of the electrodes lies a static mixer which makes the measurement more accurate by fully blending the two media when they flow through the electrodes.
Laboratory tests are carried out with the prototype of the sensor at various oil-water mixing ratios, fluid flow rates, and temperatures. Results show that the average margin of error is within ± 3%. Higher accuracy is seen when high water cut and flow rate enable oil globules to disperse more evenly and the space in between to get wider and the RMS error is less than 2%. If the water cut drops below 80%, the aggregation of the droplets will cause wild fluctuation and more errors in the measurement. In addition, the mineralization of the mixture directly changes its conductivity, which largely impacts the result. Meanwhile, temperature can influence the ionic movement intensity and then alter the conductivity of the medium. Therefore, in practice, the sensor calibration needs to be performed according to the range of medium salinity, and the temperature of the medium is collected in real time for temperature compensation. It is shown that after the adjustment, the water cut measurement results have higher accuracy and consistency.
The impedance sensor can realize online water cut monitoring for a single-layer, indicated by tests. It is more suitable for the increasing high water cut oilfields in that it is more accurate as the water cut grows.

Abstract
A depleted gas field is selected as CO2 storage site for future high CO2 content gas field development in Malaysia. The reservoir selected is a carbonate buildup of middle to late Miocene age. This paper describes an integrated modeling approach to evaluate CO2 sequestration potential in depleted carbonate gas reservoir. Integrated dynamic-geochemical and dynamic-geomechanics coupled modeling is required to properly address the risks and uncertainties such as, effect of compaction and subsidence during post-production and injection. The main subsurface uncertainties for assessing the CO2 storage potential are (i) CO2 storage capacity due to higher abandonment pressure (ii) CO2 containment due to geomechanical risks (iii) change in reservoir properties due to reaction of reservoir rock with injected CO2. These uncertainties have been addressed by first building the compositional dynamic model adequately history matched to the production data, and then coupling with geomechanical model and geochemical module during the CO2 injection phase. This is to further study on the trapping mechanisms, caprock integrity, compaction-subsidence implication towards maximum storage capacity and injectivity. The initial standalone dynamic modeling poses few challenges to match the water production in the field due to presence of karsts, extent of a baffle zone between the aquifer and producing zones and uncertainty in the aquifer volume. The overall depletion should be matched, since the field abandonment pressure impacts the CO2 injectivity and storage capacity. A reasonably history matched coupled dynamic-geomechanical model is used as base case for simulating CO2 injection. The dynamic-geomechanical coupling is done with 8 stress steps based on critical pressure changes throughout production and CO2 injection phase. Overburden and reservoir properties has been mapped in Geomechanical grid and was run using two difference constitutive model; Mohr's Coulomb and Modified Cam Clay respectively. The results are then calibrated with real subsidence measurement at platform location. This coupled model has been used to predict the maximum CO2 injection rate of 100 MMscf/d/well and a storage capacity of 1.34 Tscf. The model allows to best design the injection program in terms of well location, target injection zone and surface facilities design. This coupled modeling study is used to mature the field as a viable storage site. The established workflow starting from static model to coupled model to forecasting can be replicated in other similar projects to ensure the subsurface robustness, reduce uncertainty and risk mitigation of the field for CO2 storage site.
