في عالم النفط والغاز النابض بالحياة، يساهم كل نشاط، من الحفر إلى التكرير، في سلسلة الإنتاج المعقدة. ويُعد نشاط الفاصل جانبًا أساسيًا من جوانب هذه العملية، غالبًا ما يتم تجاهله ولكنه ضروري للغاية.
يشير نشاط الفاصل إلى العمل الذي يتم إجراؤه خلال وقت الفاصل - الفترة ما بين بدء الحفر (بدء الحفر) وانتهائه (إنهاء الحفر) لمنصة الحفر أو أي معدات أخرى. ويتضمن ذلك مجموعة واسعة من المهام التي تشمل عمليات على القاع و خارج القاع.
أنشطة على القاع تتضمن بشكل مباشر عملية الحفر، مثل:
أنشطة خارج القاع تشتمل على المهام التي تحدث أثناء عدم الحفر بشكل مباشر، بما في ذلك:
المهدات تمثل نوعًا محددًا من نشاط الفاصل، تحدث بين عمليات الحفر عند سحب سلسلة الحفر من البئر. تُتيح هذه الفترات مهامًا أساسية مثل:
نشاط الفاصل أساسي لتحسين الكفاءة والسلامة في إنتاج النفط والغاز. ويشمل ذلك التخطيط الدقيق والتنسيق والخبرة لضمان الانتقال السلس بين مراحل الحفر والإنتاج المختلفة. فهم تفاصيل نشاط الفاصل وأهمية المهدات يساعد أصحاب المصلحة على اتخاذ قرارات مستنيرة فيما يتعلق بتخصيص الموارد والجدول الزمني للمشروع والسلامة التشغيلية.

Instructions: Choose the best answer for each question.
1. What does "span activity" refer to in the oil and gas industry?
a) The process of refining crude oil into usable products.
Incorrect. Refining is a separate process.
b) The time period between spudding in and spudding out a well.
Correct! This is the definition of span activity.
c) The activities conducted during a well's production phase.
Incorrect. Production activities are distinct from span activities.
d) The environmental impact of drilling operations.
Incorrect. Environmental impact is a separate concern.
2. Which of these is NOT an on-bottom activity?
a) Drilling
Incorrect. Drilling is a core on-bottom activity.
b) Logging
Incorrect. Logging is also an on-bottom activity.
c) Casing
Incorrect. Casing is an on-bottom activity.
d) Rig maintenance
Correct! Rig maintenance is an off-bottom activity.
3. What is a "hammock" in the context of span activity?
a) A specialized tool used for drilling.
Incorrect. Hammocks are not tools.
b) A period of time between drilling operations.
Correct! Hammocks are periods between drilling operations.
c) A type of environmental monitoring method.
Incorrect. Hammocks are not related to environmental monitoring.
d) A specific type of casing used for wells.
Incorrect. Hammocks are not a type of casing.
4. What is a key reason why span activity is considered vital?
a) It allows for faster completion of the drilling process.
Correct! Span activity optimizes efficiency and timelines.
b) It helps reduce the environmental impact of drilling.
Incorrect. While important, environmental impact is not the primary reason.
c) It allows for the extraction of different types of hydrocarbons.
Incorrect. Extracting different hydrocarbons is not the primary focus of span activity.
d) It facilitates communication between drilling teams.
Incorrect. Communication is important, but not the sole reason for span activity.
5. During a hammock, which task is commonly performed?
a) Removing the drill bit.
Incorrect. Removing the drill bit is an on-bottom activity.
b) Installing downhole equipment.
Correct! Installing downhole equipment is a common hammock task.
c) Conducting environmental impact assessments.
Incorrect. Environmental assessments are typically conducted separately.
d) Training new drilling personnel.
Incorrect. Training is not typically part of a hammock.
Scenario: You are a drilling supervisor overseeing a well that has just been spudded in. The drilling plan includes running casing after reaching a specific depth.
Task: Create a brief plan for the span activity associated with this well, focusing on the upcoming "hammock" for casing installation. Include:
