The company’s vision and motivator is the thirst for a greater knowledge of the well system, which combines the well completion and reservoir TGT Oilfield Services, the market leader in through-barrier diagnostics for the oilfield, has grown year-on-year even during the downturn and the company expects to see an improvement in both activity levels and pricing as the industry stabilises further.   "Despite the drop in oil price, the demand for TGT diagnostic services grew significantly. Our focus on technology and applications that diagnose the performance and integrity of existing wells is exactly what our clients needed during the tough budget years.   "We expect that need to continue. We protect our market share and growth by continuing to fund technology development despite the market climate. Customers recognise the depth of our technical and sub surface knowledge, which has been built up over the last 20 years," says Maged Yassin, business unit manager, TGT Saudi Arabia. The company’s vision and motivator is the thirst for a greater knowledge of the well system, which combines the well completion and reservoir. This speaks for itself when one considers that more than a third of its headcount is dedicated to R&D and technology development, says Yassin.   Recently, TGT migrated its sensors to a custom-built ‘low-noise’ hardware – Indigo – designed to operate at ‘low noise’ so not to interfere with its acoustic-based ‘spectral’ and electromagnetic-based ‘EmPulse’ diagnostic systems.   Additionally, the company added a real-time capability to its fleet of through-barrier diagnostic systems. The new real-time technology enables well data to be viewed and analysed at surface during the execution of well diagnostic programmes without compromising on measurement fidelity. "We never stop, continuously improving our services and our offerings," says Yassin.   TGT provides a wide range of through-barrier diagnostics. Patented technologies are deployed on any conveyance and sense beyond the well bore to answer multiple reservoir flow and well integrity questions. The company offers these services in Saudi Arabia via in-country assets, geoscience and advanced interpretation as well as business development and field operations. TGT was founded on research and development. "Our technologies include advanced flow profiling deep into the reservoir, unconventional and fracture flow, multi annuli leak detection and multi barrier corrosion among others. We pride ourselves not only on equipment technology but also advanced geoscience and interpretation capabilities," he says.   "Saudi Arabia represents one of our most significant markets," he says. TGT has in place a stringent Saudisation development plan and technical knowledge transfer through academia alliances. Referring to Saudi Aramco’s In-Kingdom Total Value Add (IKTVA) plan, he says the published target is 35 per cent by 2020. "TGT will comply with or exceed these targets on all fronts (equipment, human capital, safety and environment) as we establish ourselves further in the kingdom," he asserts. On the company’s relationship with Saudi Aramco, he says Aramco is a highly sophisticated organisation, with a strong emphasis on strategic planning to optmise operations.   "Our relationship, like with all our customers, is built on a foundation technical competence, respect for the accuracy of the results we provide and our service delivery. We ensure we understand the customer’s challenges before designing a bespoke programme to determine the answers they seek," he says.   Referring to business growth, Yassin says business has gradually improved in the last two years in terms of activity.   Pricing of services remains a challenge. The significant rebound of oil price will soon cascade to the market to ensure continued technology development and growth.   "TGT Saudi Arabia is one of our key dedicated business units, supported by a solid global infrastructure. While we continue to expand our global footprint, we will ensure we stay focused on our customers, proving the quality of our diagnostic results, striving to set ourselves apart from our competition," he says.

To celebrate, TGT invited employees, customers, and business partners to an evening which relived the company’s scientific breakthroughs using acoustic, thermal and electromagnetic energy to reveal unique answers within and beyond the well bore.   Dr. Arthur Aslanyan, TGT’s Co-Founder commented, “It gave me great pride to attend the event and celebrate the company's 20th anniversary. We have come a long way since we first started the business. We are very excited about our future as the company continues to thrive”.   The event was attended by Saad Bargach, TGT Chairman and LimeRock Partners -private equity investors.   Hegazi continued, “Looking to our future, TGT is releasing several lines of new technologies and applications in coming months to further cement our position as pioneers of Through-Barrier Diagnostics. Our patent technology developments coupled with our unrivalled Geoscience organisation and global footprint, provide unique and reliable diagnostic services to our customers. This has been key in maintaining our fast growth trend and industry reputation. I am confident this foundation along with our excellent teams, will continue to fuel our growth for many years to come.

Come join us at IPTC 2020 at booth PF31, Hall 5 and let us take you on a journey of discovery. Diagnosing well system performance is challenging. Flow and Integrity exist anywhere within the well system, including beyond the wellbore, behind casing, and in the deepest peripheral recesses of the well system—a place virtually impossible to deploy diagnostic sensors. We will show you how we see through barriers to reveal accurate diagnostics about your well system.   The 12th edition of the International Petroleum Technology Conference (IPTC) will be held for the first time in the Kingdom of Saudi Arabia, with Saudi Aramco serving as the Exclusive Host Organisation. IPTC is a collaborative effort among the American Association of Petroleum Geologists (AAPG), the European Association of Geoscientists and Engineers (EAGE), the Society of Exploration Geophysicists (SEG), and the Society of Petroleum Engineers (SPE).   Regional energy ministers, industry leaders, and governmental representatives will have an opportunity to discuss and share their views on timely industry topics and trends, exchange expertise and experience, present state-of-the-art technology and innovation, and to stimulate further research of technical and business activities.

Challenge Multistage fracturing is a highly effective development strategy for ultralow- to low-permeability reservoirs. However, in uncemented completions with fracturing sleeves and packers, it can be challenging to identify fracture initiation points and confirm the number of fractures initiated in each treatment.   A lateral wellbore in a horizontal gas producer was completed with more than 3,000 ft of open hole (OH) section across five fracturing stages in a high-temperature and high-pressure tight-gas interval. This well presented several key challenges.   With OH intervals ranging from 200 to almost 1,000 ft, the operator could not be sure how many fractures had been created or where precisely these fractures were located. The initial stage plan was not sufficient to guide packer placement. Placement had to be decided in conjunction with the caliper log and gauged hole analysis. Interstage communication owing to packer bypass or ball failure is a common problem in completions of this kind. This can be caused by higher differential pressure being exerted on the packers during fracturing. Figure 1: Active frac ports and fracture distribution across all stages and three bypassed packers. Solution Fracture Flow is delivered by TGT’s analysts and engineers using the True Flow system with Chorus and Cascade platforms. Integrating insights from a Chorus acoustic survey and Cascade temperature and flow modelling with the production logs, OH logs and calculated rock mechanical properties provides a better understanding of the fracturing process, completion performance and production performance in an OH multistage fracturing completion.   Chorus acoustics and Cascade flow modelling provided a quantitative assessment of flowing fractures and stagewise production from the reservoir behind the liner.   Multi-array production logging results quantified the flow and flow profile inside the horizontal liner. The integration of datasets was conducted in a single deployment to deliver a comprehensive understanding of well completion and production, including clear identification of water-producing intervals. Figure 2: Flow geometry and contribution across the horizontal section. Result The Fracture Flow diagnostic programme evaluated the active fracture ports and fracture contribution in each stage. It also enabled the team to assess the packers, completion integrity, and production distribution behind the liner (Figure 1). Multi-array production logging was used to investigate the flow profile entering the liner.   The survey results identified 34 active fractures and showed that some flow was bypassing several packers. Figure 2 shows the reservoir flow profile provided by Cascade and the True Flow system. Most fractures were clustered around Stage 4 and Stage 5, and this had a major impact on production. Survey results revealed good completion integrity overall, with only three bypassed hydraulic packers. The dual packer isolation systems were shown to prevent communication between contributing stages.   Based on the comprehensive analysis result the water being produced from all fracture entry ports except Stage 5, where water contribution was minimal. Engineering work decreased the water–gas ratio to 5%.
