The graph shows estimated oil production capacity for several Gulf countries between 1990 and 2010.
Sample Response
The column graph compares estimatedprobable oil production capacitycapabilities of six Gulf countries from 1990 to 2010. Overall, Saudi ArabiaArabi was the leading oil-producing countryleading oil generating country and its production increased faster than the remaining five countries. As shownAs is presented, the estimated oil production capacityoil producing capability in Iran in 1990 was around 3 million barrels each day which reached 4 millionreached to 4 million after 15 years and finally in 2010, the production slightly improved. Iraq’s oil generating capability was slightly lower than that of Iran and its production capacityoil stock in 1990 was roughly 2 millionbillion barrels per day and it rose to about 3.5 million barrels per dayit almost doubled in 2010. Kuwait, on the contrary, produced less than 2 million barrels per dayless than 2 billion barrels daily and itstheir production amount stool at approximately 3.5 million in 2010. Moreover, Qatar, throughout the decades, had the lowest production capacityproduced the lowest oil which stood atwhich accounted for roughly 0.5 million barrels each day and after two decades, its production level remained at the same level. Oil generation per day in the United Arab Emirates showed a similar pattern to that of Iraqa similar pattern that of Iraq and its production reached nearly 4 million barrelsits production reached to nearly 4 million barrels in 2010. Finally, Saudi Arabia’s oil generating level was the highest and significantly higher than that of other countries. In 1990, it produced over 8 million barrels per dayover 8 million barrel daily which was approximately four times higher than that of other countries. Its daily production soared to well over 14 million barrel and this was marginally the same as the cumulative oil productions of other five countries.
Why this response received Band 6.5
The response identifies the dominant position and rapid growth of Saudi Arabia and supports this overview with generally relevant comparisons across all six countries. Its main limitation is imprecision, especially the repeated use of billions instead of millions and several awkward or inaccurate descriptions. Prioritise exact units and cleaner comparative language while organising the detail into clear groups.
IELTS Writing Criteria Scores
Task Achievement
A clear overview and coverage of all countries are provided, but some figures and units are inaccurate or imprecise.
Check every unit against the chart and group countries by similar trends to sharpen the comparisons.
Coherence and Cohesion
The information follows a broadly logical country-by-country sequence, though the single dense paragraph and repetitive progression weaken organisation.
Separate the overview from two grouped detail paragraphs and use referencing to reduce repeated mentions of production.
Lexical Resource
There is enough range to describe trends and comparisons, but frequent collocation and word-choice problems reduce precision.
Use standard chart language such as production capacity, rose to, remained stable, and combined output accurately.
Grammatical Range and Accuracy
A mix of simple and complex structures communicates the data clearly overall, despite recurring agreement, article, preposition, and noun-form errors.
Edit recurring forms such as barrels, reached, and that of, and keep country references consistently singular.
