The graph shows estimated oil production capacity for several Gulf countries between 1990 and 2010.
Sample Response
The bar chart compares the estimated daily oil production capacitydaily oil production in sixfive Gulf countries between 1990 and 2010. Overall, oil production capacityoil generation in Saudi Arabia was the highest and Iran, Iraq, Kuwait and the UAE had broadly similar production capacitiesIran, Iraq, Kuwait and the UAE produced nearly the same amount of oil. As the diagram suggests, Saudi Arabia produced over 8 million barrels of oilbarrels oil per day in 1990, the highest figure shownin 1990 which was the highest. Its production went as high as 15 million daily after 2 decades. Notably,It is worth noticing that, Saudi Arabia’s production capacityoil stock was roughly comparable with the other countries' combined capacitysomewhat similar to the rest of the countries collectively. Oil productiongenerating capacity in Iran, Iraq, Kuwait and the UAE was almost the same in 1990, around 2-3 million barrels daily. Over timeOver the time their production capacity increaseddeveloped and reachedreached to around 4 million barrels in 2010. Iran’s production was marginally higher than that of Iraq, Kuwait and the UAE. The least amount of oil production was recorded in Qatarcould be observed in Qatar, less than 1 million barrelsbarrel in 1990 and this capacity remained exactly the same except in 2000there except in 2000 when its capacity briefly increasedproduction slightly progressed.
Why this response received Band 6.5
The response clearly identifies Saudi Arabia’s dominance and gives a sensible comparison of the other countries, with most figures and trends matching the chart. Its main weakness is imprecise wording and occasional factual framing, including calling the display a comparison of five countries when six are shown. Focus on reporting capacity with exact country coverage and more natural data-description collocations.
IELTS Writing Criteria Scores
Task Achievement
The overview and principal trends are well selected and largely accurate, but the introduction incorrectly states that five countries are shown and some figures are broadly rounded.
State that all six countries are compared and support the overview with precise start-to-finish figures for the main groups.
Coherence and Cohesion
Information moves clearly from the overview to Saudi Arabia, the middle-producing group, and Qatar, although the report is presented as one dense paragraph.
Separate the overview and grouped details into distinct paragraphs to make the progression easier to follow.
Lexical Resource
There is a sufficient range of comparative vocabulary, but collocations such as oil generation, oil stock, reached to, and production progressed are unnatural.
Use consistent technical phrasing such as production capacity rose to, remained stable, and barrels per day.
Grammatical Range and Accuracy
The response uses varied sentence structures with generally clear meaning, despite recurring errors in articles, prepositions, punctuation, and singular-plural agreement.
Proofread noun phrases and verb patterns, especially barrels of oil, over time, reached, and one million barrels.
