عدم التأكد الكلي: لغز في صناعة النفط والغاز

يشكل مصطلح "عدم التأكد الكلي" في صناعة النفط والغاز، على الرغم من استخدامه المتكرر، مفهومًا متناقضًا. بينما يُستخدم غالبًا لتسليط الضوء على عدم القدرة على التنبؤ بالصناعة، فإن تعريف "عدم التأكد الكلي" نفسه يشير إلى حالة معرفية مستحيلة – حالة لا يُعرف فيها شيء على الإطلاق.

الوصف الموجز:

من الناحية التعريفية، فإن عدم التأكد الكلي هو مفهوم نظري لا تتوفر فيه أي معلومات، ولا يُعرف شيء. يشير هذا إلى سيناريو مستحيل حيث حتى وجود رواسب النفط والغاز غير معروف تمامًا.
غالبًا ما يُستخدم المصطلح بشكل مجازي، مما يؤكد على مستوى المخاطر وعدم القدرة على التنبؤ المرتفعين المرتبطين بالاستكشاف والإنتاج. تساهم عوامل مثل التكوينات الجيولوجية وخصائص الخزان وتقلبات السوق جميعها في طبيعة صناعة النفط والغاز المعقدة وغير المؤكدة.
من الناحية العملية، لا يوجد "عدم تأكد كلي" حقًا. حتى في المراحل المبكرة من الاستكشاف، توفر المسوحات الجيولوجية والبيانات الزلزالية والسجلات التاريخية بعض مستويات المعرفة، وإن كانت غير كاملة.

لماذا يستمر هذا المفهوم؟

على الرغم من عدم جدواه، يظل "عدم التأكد الكلي" أداة مفيدة لـ:

تسليط الضوء على المخاطر المتأصلة: يُستخدم المصطلح لتذكيرنا بطبيعة صناعة النفط والغاز غير المتوقعة، مما يؤكد على الحاجة إلى استراتيجيات إدارة المخاطر القوية.
تشجيع ثقافة الحذر: من خلال الاعتراف بوجود عدم اليقين المتأصل، يصبح صانعو القرار أكثر عرضة للنظر في مجموعة من النتائج المحتملة وتطوير خطط طوارئ.

التحرك إلى ما بعد هذا المفهوم:

بينما قد يكون "عدم التأكد الكلي" أداة مجازية مفيدة، من المهم الاعتراف بحدوده. بدلاً من ذلك، يجب التركيز على:

تحديد الكميات غير المؤكدة: من خلال تحديد وتحليل حالات عدم اليقين المحددة، يمكن للشركات تطوير استراتيجيات أفضل لتقييم المخاطر وتخفيفها.
تحسين جمع البيانات وتحليلها: تسمح التقنيات المتقدمة وتقنيات تحليل البيانات بفهم أفضل للتكوينات الجيولوجية وخصائص الخزان، مما يقلل من حالات عدم اليقين.
اعتماد نهج احتمالي: يشمل هذا النظر في مجموعة من النتائج المحتملة واحتمالاتها المصاحبة، مما يسمح باتخاذ قرارات أكثر استنارة.

في الختام، بينما يظل "عدم التأكد الكلي" عبارة قوية داخل صناعة النفط والغاز، من المهم إدراك حدوده. من خلال الاعتراف بقدرات الصناعة المعقدة والتركيز على تحديد كميات عدم اليقين، يمكن للشركات التنقل في التحديات واتخاذ قرارات أكثر استنارة في هذه البيئة المتغيرة باستمرار.

Exercise: The Unconventional Well

Scenario: A new oil and gas company is exploring an unconventional shale play in a remote region. They have preliminary geological data, but many uncertainties remain regarding the size and quality of the potential reservoir. The company needs to decide whether to invest in drilling a test well.

Task:

Identify at least 3 specific uncertainties that the company faces.
Suggest 2 ways the company can try to quantify or reduce these uncertainties before making a drilling decision.
Explain how the company can use a probabilistic approach to evaluate the potential outcome of drilling the test well.

Exercice Correction

Here's a possible solution:

1. Specific Uncertainties:

Reservoir Size and Thickness: The preliminary data may not accurately reflect the true extent of the shale formation or the thickness of the productive layers.
Permeability and Porosity: The ability of the shale to hold and release oil and gas (permeability) and its ability to store hydrocarbons (porosity) are crucial factors, but often difficult to predict accurately.
Production Rate: The rate at which the well can produce oil and gas will depend on various factors, including reservoir characteristics, well design, and stimulation techniques.

2. Quantifying or Reducing Uncertainties:

Further Geological and Geophysical Studies: Conducting additional seismic surveys, core analysis, and well logs can provide more detailed information about the reservoir, helping to refine the estimates of size, permeability, and porosity.
Analogous Field Studies: Comparing the new play to similar shale formations in other regions can help assess potential production rates and overall success.

3. Probabilistic Approach:

The company can build a model considering different possible scenarios for each uncertainty (e.g., low, medium, high reservoir size, porosity, and production rate) and assign a probability to each scenario based on available data and expert opinions. This allows for a range of potential outcomes and helps quantify the risk associated with drilling the test well.

For example, they might estimate the probability of a successful well, based on historical data from similar plays, to be 60%. They could then factor in various production scenarios for each successful well and assign probabilities to each. This process will give them a clearer picture of the potential rewards and risks associated with the test well investment.
