An Innovative ICD Design Workflow to Balance Flux Equalization and Well Productivity in Horizontal Wells
Authors: Lee Byung , Faizal Syed Abu , Galimzyanov Artyom
Published: February 2017

During the last decade, inflow control device (ICD) technology has rapidly developed and widely been used in horizontal wells due to its effectiveness in flux equalization and mitigation of unwanted fluid breakthrough. An ICD completion achieves flux equalization and manages water breakthrough by introducing an extra pressure drop in the ICD and redistributing the drawdown across the sandface between high and low permeable intervals of a horizontal well. This additional pressure loss in the ICD completion will cause reduction of effective productivity of the well, in other words it will require lower flowing bottom-hole pressure for a well with ICD completion to produce the same liquid rate compared to a well with a barefoot completion. The higher the pressure drop across the ICD completion, the better will be the equalization effect and water mitigation. Subsequently, the reservoir pressure has to be used wisely during field development as expensive pressure maintenance programs are utilized in many fields as part of the field development plans.

This study tries to answer an important question: What should the optimum pressure regulation in an ICD completion be to realize the benefits of ICD without excessive reduction of well productivity? The effect of ICD regulation on flux equalization and well productivity reduction for various cases of well productivity index (PI) and permeability variation were studied through numerous static near wellbore simulation runs. Dynamic reservoir simulation was conducted to verify the results from the static simulation and dependence of the degree of flux equalization along the horizontal section on water breakthrough deferment and the oil recovery factor.

An ICD design workflow is presented, which can be used to select an optimum ICD design, which maximizes the benefits of ICD with the least reduction in well productivity. A trade-off chart between well productivity and the degree of influx equalization has been built, which helps to determine the optimum pressure drop across an ICD completion in the presence of various levels of permeability variation along the wellbore. This approach can provide quick and simple calculation for the required ICD strength or number of ICD joints along the wellbore to maximize recovery of hydrocarbons. A real field case is used to illustrate the effectiveness of this workflow for optimum ICD design.

Developing reserves in the North Russia, Usinsk requires the operator to drill extremely abrasive sandstone formation at bottom of 8.625-in. reservoir section. Drilling with PDC bits has been challenging due to severe cutter wear. Heavy-set standard PDC cutter bit would last on average from 45 to 100 meters depending on field. With the goal of increasing production and reducing costs, reservoir section can be from 170 up to 350 meters long.

With standard PDC bits, it would take from three to four bits to finish the interval. The operator required new type of PDC bit that could efficiently drill abrasive sandstone at high ROP and cutting structure that would remain sharp over longer interval.

To develop a durable bit solution, engineers used an FEA-based modeling system to implement an innovative bit by positioning new shearing elements (rolling cutters) to address cutter wear. Several designs were implemented that hold the cutter securely in place and allow full cutter rotation. Rolling cutter PDC shearing element utilizes the entire 360 degree of diamond edge to shear the formation while reducing frictional heat and, by strategic positioning of these rolling cutters in the high wear areas of the bit, provides longer footage and higher ROP.

New design 8-bladed PDC bit with rolling cutters was tested and compared against direct offsets in two different fields in Usinsk, Russia. In first field, rolling cutter bit drilled entire reservoir section 335 meters with 4.6 m/hr ROP improving 140% meterage and 44% ROP. In second field, two rolling cutter bits drilled reservoir section and replaced four standard PDC bits saving three days.

New concept of PDC bit utilizing rolling cutter expands the limit of PDC bit durability drilling extremely abrasive sandstone formations. New type of bit can efficiently drill in those challenging geological conditions improving the drilling time and cost.

Historically it has been a challenge to rapidly produce a geomodel that can honor the detailed form of complex faulting and folding, while enabling sensible property modeling and that is tailored to fluid flow simulations. In structurally complex areas, the construction of accurate 3D geological models is often impeded by the complexity of the fault framework, the resulting layer segmentation, "multi-z" horizons in compressive settings and steeply dipping to overturned layers. In particular, standard geocellular models, such as pillar grids, may fail to honor complex structural features.

To address those issues, methodologies using a mapping between the geological space and a 3D parametric space — often referred to as depositional space — have been described in the literature for geological grid construction and property population. Using case examples of structurally complex settings, we illustrate a depositional unstructured grid construction workflow. Compared to known methodologies, the depositional space is computed using a geomechanically-based approach. We illustrate that the methodology allows for complex structural configurations to be effectively modeled and transformed into a geocellular model honoring the full structural complexity. Our depositional unstructured model can then be populated with properties and used directly for flow simulations.
Integrated Workflow on Lithofacies Modeling

Published: February 2017

3D lithofacies modeling is a key step in depositional environment analysis. 1D lithofacies modeling along the wellbore is an essential contributor to the 3D modeling. This paper introduces an integrated workflow from 1D to 3D lithofacies modeling and the application of this workflow in an oil and gas field.

This study focused on the integration of core description, conventional log curves, image logs data and interpretation. All the core descriptions have been digitally described or digitized and coded so those can be easily loaded and recognized by digital applications. After data loading, 1D lithofacies models were built using the Artificial Neural Network (ANN) method and a blind test was then conducted to check if the models meet the requirement. When the blind test results were satisfactory, the ANN models would then be applied to the un-cored wells to predict the lithofacies at those wells. Wellbore image logs were then used to smooth the final results which would be used to build the 3D lithofacies models throughout the whole field.

The workflow was applied in one of the oil field in the study area and the results were quite exciting. There are five types of lithofacies in the studied reservoirs but there is only one lithofacies predicted before using the porosity cutoff. With this new workflow, all five lithofacies were predicted and the accuracy of the prediction was greatly improved. An overall matching rate between the core description and the prediction is above 70% after smoothing with wellbore image logs.

A 3D lithofacies model was then created using the result from the 1D lithofacies modeling. With the 3D model, the lithofacies distribution can be easily captured and the depositional environment can be analyzed to determine the potential good reservoirs.

Accretion is a common phenomenon that affects drilling operations in the Orinoco Heavy Oil Belt. The main reservoir, where most horizontal sections are drilled, is the Oficina Formation. Accretion negatively impairs operational efficiency, thus generating stuck pipe incidents, problems while tripping due to high torque and drag values related to friction factors, and the unrecommended backreaming operations. In addition, accretion causes excessive fluid surface losses linked to plugged shakers screens.

This document shows the laboratory tests and successful field results obtained from the combination of specialized surfactant and lubricant agents working in synergy to reduce the accretion effect. The laboratory test demonstrated the synergy between the lubricant and surfactant in different tests, such as lubricity, accretion, and permeability damage testing. In the field, positive results were achieved in nine horizontal wells, thus increasing operative efficiency by reducing stuck pipe incidents, backreaming operations, and unplanned trips. This impact over flat times was also accompanied by a fluid waste reduction that improved the shakers’ screen usage and reduced the amount of oil coating the cuttings, which facilitated the treatment process and minimized environmental impact.
Effective Removal of Sour Gases Containing Mercaptans in Oilfield Applications

Published: February 2017

Hydrogen sulfide and mercaptans are highly toxic. They can cause corrosion and contaminate fuels. For safe and efficient operation of oilfield applications, it is important to remove these constituents. Processes to remove sour gases with mercaptans include treatment of the hydrocarbon fractions with caustics, clays and hydro-treating, as well as the UOP Merox™ process. Another method comprises scrubbing with mono or di-ethanolamine in a regenerative amine system. These methods are ineffective in removing mercaptans.

Scavengers react more quickly with hydrogen sulfide than with other sour gases. For this reason it is a challenge to develop scavengers that scavenge all components of sour gas including mercaptans effectively.

This paper describes a new formulation that simultaneously scavenges hydrogen sulfide and mercaptans extremely efficiently. A new lab experimental procedure is presented that mimics the scavenging of sour gas in a tower application. The procedure uses a new analytical technique that simultaneously detects hydrogen sulfide and mercaptans. Gas concentrations of hydrogen sulfide and methyl mercaptan are detected before and after scavenging. Systematic performance evaluations show that the new scavenger simultaneously scavenges hydrogen sulfide as well as mercaptans.

This document describes the methodology established to optimize the electrical energy consumption in electric submersible pumping systems, considering not only the current operating conditions but also the expectations in operational and production forecasts of an operator in the Caracara of Colombia. The effect of the optimization on the economic and operational system was to improve profitability by reducing energy consumption, hence electric cost, and the change in distribution of electric load in the block allowed attacking the limitations to increasing production related to the load in generation capabilities.

Cepsa Colombia began exploration in Colombia in 2001 by working in two exploration and production areas, Llanos basin and the upper Magdalena river with seven exploratory blocks and three production blocks. The total audited average oil production was 23,000 BOPD as of February 2015. Caracara block contributes 76% of this production.

The Caracara block has an average water cut ranging from 80% to 90%. There are 84 production wells in the block, and electric submersible pumps (ESPs) are the only artificial lift method.

Hydraulic fracturing activities in tight gas wells in Saudi Arabia have been exponentially increasing to meet domestic demand for natural gas. During each fracturing stage, up to 125,000 gallons of groundwater is currently being used. The need to reduce groundwater usage during fracturing treatments has been set as a priority, and alternative water sources for fracturing applications that can significantly reduce groundwater usage have been intensively explored. One such alternative water source is seawater as a base fluid for hydraulic fracturing. The primary challenge for this application is the tendency for scale precipitation due to the high sulfate content in seawater and its potential incompatibility with formation water. Without proper prevention and mitigation measures, this scale precipitation can induce formation damage and reduce the fracture conductivity. To minimize scaling tendencies, an in-house multidisciplinary team has performed extensive collaborative research to identify a scale inhibitor appropriate for Arabian Gulf seawater and formation water. Scale precipitation can be further mitigated by filtering the seawater with a nanofiltration system to dramatically reduce the sulfate ion as well as lower the calcium and magnesium ions. The successful application of seawater-based fracturing fluid in Saudi Arabia opens up the door to minimizing consumption of groundwater in hydraulic fracturing operations. Millions of gallons of groundwater could be saved and development of sustainable water resources could be achieved. This paper will describe the optimization of a scale inhibitor and fracturing fluid system, the selection of the nanofiltration system, and the first field applications of the seawater based fracturing fluid system in high-temperature gas wells in Saudi Arabia.

Published: February 2017

After great success of 4D seismic (Time-lapse) in clastic environment lot of 4D projects started 10 years ago in carbonates. Because of a smaller petroelastic response to reservoir modification lot of reservoirs enginners and geophysicists considered that 4D in carbonate has a very little probability of success.

To check the capacity of 4D seismic to work in carbonate environment ADMA decided to acquire a 4D pilot on one of their giant field. The design of this pilot has been chosen to mimic as perfectly as possible the base survey. Then another acquisition has been performed with a fully different design that reduces drastically the cost of survey. TOTAL had the great opportunity to process, invert and interpret these datasets. This paper will show some comparison of 4D results obtained from the 2 designs.

TOTAL performed a lot of QCs allowing to get a very good appreciation of degradation in repeatability and increase of noise levels linked to acquisition design. The regular QCs as NRMS or predictability are compared but also some new in house TOTAL QCs as SDR (Signal Distortion Ratio), Noise Xplots, etc… Next relevant 4D attributes (like relative changes in P velocities and in P impedances) are computed using in house algorithms that have been developed on numerous Total portfolio cases. They can be compared for both designs using as reference the pilot which is considered closer to reality.

A first step was to validate 4D anomalies out of pilot area by comparing them to geological features and production knowledge. So we got the proof of real 4D anomalies related to clear production phenomena, validated by the asset team.

Second step was to evaluate the stability of 4D results despite the acquisition design modification and the strong variation of noise level. It is obvious and expected that the "non repeated" design introduces a degradation of the quality of 4D results. Key points are on one hand to check if the 4D processing can handle these differences successfully and another hand to define recommendation to acquire a successful and cost-effective monitoring survey.

In conclusion this example shows that 4D seismic in carbonates, oil/water system; with difficult seismic environment is definitely possible under condition that acquisition, processing and inversion of 4D seismic are conducted with care to avoid the weakest link limits value of 4D information
Petrophysical Joint Inversion of Multi-Geophysical Attributes and Measurements for Reservoir Characterization
Authors: Rovetta Diego , Colombo Daniele , Turkoglu Ersan
Published: February 2017

Interpretation of petrophysical parameters such as porosity and saturation is very important for reservoir characterization and resources evaluation. Petrophysical inversion is typically done using well log data to characterize the reservoirs. Seismic and electromagnetic (EM) measurements are sensitive to different rock properties and their joint interpretation can improve the characterization results. We address the task of improving the interpretation of porosity and fluid saturation in the reservoir rocks by means of the joint inversion of seismic, gravity and EM data subject to geological constraints. Simultaneous inversion is expected to provide higher sensitivity, better resolution, and an overall more robust estimation of rock parameters than conventional log analysis. We developed in-house petrophysical joint inversion (PJI) codes and tested them on simulated and field data. We also designed a rigorous workflow for reservoir characterization through PJI of multi-geophysical attributes and measurements. First, we conduct analysis and inversion of the available well log data to understand the petrophysics of the reservoir and to choose the constitutive equations linking petrophysical attributes to geophysical ones (calibration). Second, we implement sequential PJI of geophysical attribute volumes such as seismic velocity, density and resistivity. Finally, we produce a full PJI of geophysical measurements such as seismic, gravity and EM data. Each of these steps requires the integration of geophysical, geological and petrophysical knowledge about the specific reservoir. The first step of the workflow was applied to well log data from an important reservoir in Saudi Arabia. Mineralogical information from the well logs indicated mainly calcite with some dolomite at the reservoir depth. The rock properties were adjusted with depth according to the known stratigraphy. The recalculated log resistivity, density and sonic data via joint inversion fit the observed data well. The estimated porosity and fluid saturations were the petrophysical parameters in the joint inversion while gas saturation was ignored. The joint inversion estimated porosity was similar to neutron log-derived porosity. Improved oil saturation estimates are expected to enhance the interpretation of the resource. To test the other two steps of the workflow, we created a simulated 3D multi-geophysical model by lateral interpolation and rescaling of well log data from available wells. Then, we generated the related geophysical data through forward modeling. Finally, we tested the sequential and full PJI algorithms on this dataset. We are currently working on the application of the described method and workflow to a measured dataset from a Saudi Arabian reservoir. If successful, this approach could lead to an overall more robust estimation of the reserves.

Chickpea is highly sensitive crop to weed competition as early stage of growth. A field experiment was conducted during winter season of 2013-14 to 2015-16to know the response of application of sequential application of herbicides under different sowing methods. Results revealed that chickpea sowing in reduced tillage performed better and produced higher number of pods per plant, seed yield and protein yield over conventional tillage. In weed management treatment, sequential application of pendimethalin@0.75 kg a.i./ha pre-em followed by imezethapyr @40 g a.i./ha post-em improve the crop growth and produced higher seed yield (1515 kg/ha) and protein yield. Total weed density and weed dry weight were recorded minimum under reduced tillage at both 30 and 60 days after sowing. Application of pendimethalin @0.75 kg a.i./ha pre-emfollowed by imezethapyr @40 g a.i./ha post-em reduced the total weed density and weed dry weight over other treatments and recorded minimum. Weed control efficiency recorded higher with conventional tillage (70.04%) and closely followed by reduced tillage (70.81%). Pendimethalin@0.75kg a.i./ha pre-emfbimazethapyr @ 40 g a.i./ha recorded highest weed control efficiency (92.93%) followed by pendimethalin 0.75 kg a.i./ha fbquizalofop ethyl 50 g a.i./ha (85.41%) and pendimethalin 1.0 kg a.i./ha (73.78). Net return of Rs 42265and benefit cost ratio of 1.55 were also recorded higher under reduced tillage. Among weed management pendimethalin1.0 kg a.i./ha pre-em followed by imezethapyr @50 g a/i/ha post-em recorded higher net return (Rs 48782) and benefit cost ratio (1.81).
