Geomechanical Models, Studies & Analysis
The orientation of regional and borehole stresses is a controlling factor in borehole stability, development of preferential permeability, sand production and casing damage. A geomechanical model was developed to explain drilling (washouts and borehole collapse), completion (high fracture tortuosity) and production (sanding) problems experienced during the development of overpressured laminated shaly sandstone reservoirs in the Burgos Basin, northern Mexico. In the absence of core data, the model used rock mechanical properties derived from conventional acoustic, porosity and resistivity logs. Additional data for the model came from imaging-log data (breakout azimuth), seismic data and drilling and completion data, such as minifrac data from the first exploratory well. The geomechanical model included porepressure and mechanical-properties models that provided an improved understanding of the total stress tensor (magnitude and orientation of the principal horizontal stresses), pore pressure, and the geomechanical properties. Model validation consisted of comparing model predictions for the occurrence of breakouts/ washouts and lost-circulation zones with actual data from earlier wells. The validated model was used to optimize the drilling (mud-weight) program, well placement, completion (perforation orientation and fracture design) and production specifications (drawdown pressure) for a new directional well. ADATT global petroleum offers a full service in all aspects of:

Sand Production Prediction Predicting and controlling sand production are critical components of choosing the right completions program and optimizing production. The main objective of each sand production.
study is to optimize the production rate by predicting the maximum sand-free drawdown. Finite-element models for different completion types are available to predict the maximum drawdown for arbitrarily oriented wells. ADATT global petroleum uses skilled interpretation to select the right sand management solution, to guide development decisions, to enable appropriate completions planning, to optimize future reservoir management and to help optimize recovery from reservoir with better sand production prediction.
Research has demonstrated that sand production is a two-step process: (1) Fail the rock, and (2) transport the product of failure (sand or rock fragments).
To predict sand failure during production, the ADATT global petroleum constructs a mechanical earth model (MEM) of the reservoir. A 1D model is used for basic risk analysis, a 3D model helps manage the entire reservoir and avoid risky well location, and a 4D model predicts the location and onset of sand production. This knowledge is captured in a Sand Management Advisor system that can predict sand failure at the production tunnel.
In addition, this solution can help

Fracture reservoir analysis Exploit relationship between in-situ stress and permeability to produce more effectively from fractured reservoir
Most carbonate reservoirs are naturally fractured and contain fractures that can range from isolated microscopic fissures to kilometer-long structures called fracture swarms or corridors. The fractures create complex paths for hydrocarbons and other fluids which impact reservoir characterization, production performance, and ultimate recovery. Let our experts use there inevitable experience to help you make better well decisions through field-specific geomechanical models enabling:
- Detection of variations in stress magnitudes affecting permeable fracture sets
- Optimization of drilling direction to intersect zones enhancing permeability
- Characterization of variations in fracture attributes in adjacent fault blocks Top of page
Improved Trajectories through Improved Insight
Knowing the orientation of permeable fractures can help you optimize well trajectories to intersect the maximum number of permeable fractures. It all starts with wellbore images, the fundamental data for optimizing reservoir drainage. Using our “drill work predict software”, we’ll characterize and classify natural fractures and faults, giving measurements of orientation, distribution, and apparent aperture. Next, “drill works predict” is used to analyze the fracture data, along with the reservoir stress profile to determine the proximity of fracture and fault sets to frictional failure. From there, your critical well planning decisions are made easier. Optimize design, drill for the permeable zones and enjoy the peace of mind—and extra profit—that comes with good decision making
Fault Seal Analysis
We use fault mapping from seismic data to understand reservoir compartmentalization for improved production.
Stress state drives the ability of reservoir-bounding faults to serve as effective fault seals. If the faults are critically stressed, repeated slip will reduce sealing properties, causing hydrocarbon leakage and limiting maximum column height. We can help you qualify fault leakage probability with reservoir geomechanics.
Understanding stress helps you understand seal stress and pore-pressure control fault reactivation. Since reactivated faults tend to be permeable, stresses resolved on faults can control fault seal integrity, hydrocarbon migration, reservoir compartmentalization, and maximum hydrocarbon column heights.
We start with accurate knowledge of reservoir in-situ stress orientation and magnitudes using our software and/or seismic data. We analyze seismically mapped fault segments with our “drill works predict” application to determine fault proximity to frictional failure, allowing us to reduce guesswork and increase your production capabilities. Also with the help of our software we can help in:

Exploratory prospect generation
We have a better understanding of the elements and processes of the petroleum generation systems, which are critical for the mapping of leads and prospects. Rich collaborative, multidisciplinary visualization infrastructure for daily work and high-level meetings. ADATT Global identifies exploratory leads and generates prospects (structural and stratigraphic) by integrated mapping of geological, geophysical, petrophysical and geochemical analysis. These can be presented as risked and ranked prospects along with economic evaluation. Application of sequence and seismic stratigraphy are used to identify reservoir facies and predict timing of structural formation. Top of page
Seismic imaging
Seismic imaging directs an intense sound source into the ground to evaluate subsurface conditions and to possibly detect high concentrations of contamination. Receivers called geophones, analogous to microphones, pick up “echoes” that come back up through the ground and record the intensity and time of the “echo” on computers. Data processing turns these signals into images of the geologic structure. Seismic imaging helps petroleum geologists to build up a detailed understanding of sub-surface structures. The resulting data can be used to identify possible oil and gas migration paths, estimate the geometry and size of potential traps, and predict directly the presence of hydrocarbons.
Seismic survey data are not only used to search for hydrocarbon accumulations, but are also important in developing new oil and gas fields and not least in managing production. Petroleum exploration is a business with high levels of risk and uncertain outcomes.
Knowledge and technology are key requirements for success. This technology allows our Geologist to see beneath the earth's surface more clearly and accurately than ever before. Using these proprietary tools, researchers have been able to find significant oil and gas reservoirs in increasingly challenging areas, such as beneath thick mountains of salt in the deepwater portion of the U.S. Gulf of Mexico.
Seismic images have become more accurate with the development of more sophisticated velocity models, which contain information about the speed with which the seismic waves travel through the rock layers. This information is critical for unraveling the geologic secrets hidden below. Recorded echoes produce a vast amount of data, and powerful supercomputers are required to process and analyze the data to form a 3-D image. Accuracy is essential: The better the images, the fewer the number of dry holes, which improves the likelihood that an exploratory well will confirm a discovery and move toward production.
ADATT Global is committed to merge seismic processing and interpretation as a way of maximizing seismic data quality in accordance with specific end-user needs. Top of page
ELECTROMAGNETIC SEISMIC DATA
Accurate determination of reservoir petrophysical parameters is important for formation evaluation and reservoir management. We estimate reservoir petrophysical parameters, such as porosity and fluid saturations, from electromagnetic and seismic measurements.
The vision of ADATT global petroleum is to take electromagnetic (EM) sensors to the permanent monitoring market and to establish it as a routine tool in hydrocarbon exploration and appraisal. It was recognized early on that reservoir monitoring systems could offer high value to operators, but at the time, existing seismic-based methods could not convincingly deliver the solutions needed which required knowledge of the reservoir fluid. While there was serious push and support from major oil companies, technology was the motivator for the company.
Advances in electronics had made it possible to combine surface and borehole electromagnetic measurements with 3D seismic and link fluid and porosity monitoring with an exact location in the three-dimensional space. ADATT global was able to accomplish this through EM technologies that offer full field reservoir identification, delineation, and monitoring through the use of sensors and methodologies. Company staff had used these technologies since the early eighties but dropped the borehole components - the key elements linking the reservoir to surface measurements - several times due to sensor realization limitations. Now the focus is on three core areas: permanent sensors to monitor production efficiency, marine electromagnetic technology as a direct hydrocarbon indicator, and borehole electromagnetic for geosteering of the drill bit to provide deep reading resistivity measurements. Together with various alliance partners the company has been developing permanent or semi-permanent EM, gravity (density), and seismic sensors that can be integrated into a monitoring system. The sensors can be placed both in the borehole and at the surface to optimize resolution and spatial coverage. Top of page
A priority today is marine time domain CSEM (CSEM) technology and robust integration with the seismic method.
To include borehole measurements a deep reading TEM (transient electromagnetics) system has been developed for geosteering. The tool is intended to provide high resolution resistivity measurements of the surrounding formation up to several tens of meters away. It is designed to link directly to single well seismic.

Formation integrity test and LEAK OFF TEST Formation Integrity Test (FIT) is the method to test strength of formation and a casing shoe by increasing Bottom Hole Pressure (BHP) to designed pressure. FIT is normally conducted to ensure that formation below the casing show will not be broken while drilling the next section with higher bottom hole pressure. Normally, drilling engineers in town will design how much formation integrity test pressure required and a unit of FIT is normally in pound per gallon unit.
A test to determine the strength or fracture pressure of the open formation, usually conducted immediately after drilling below a new casing shoe. During the test, the well is shut in and fluid is pumped into the wellbore to gradually increase the pressure that the formation experiences. At some pressure, fluid will enter the formation, or leak off, either moving through permeable paths in the rock or by creating a space by fracturing the rock. The results of the leakoff test dictate the maximum pressure or mud weight that may be applied to the well during drilling operations. To maintain a small safety factor to permit safe well control operations, the maximum operating pressure is usually slightly below the leakoff test result.
With the aid of Drillworks® Leak off Test (LOT) Analyzer we ensure valuable leak-off test data is included in the pore pressure and geomechanics workflow.
Solving for leak-off pressure and minimum stress is an easier task with LOT data captured and displayed in comprehensive pressure/volume/time plots. Using the LOT analyzer, Drillworks program users can query minimum stress values and populate pore pressure and wellbore stability models. Top of page
