Cementing is important for many reasons.
1. Cementing keeps the casing secure.
2. Cementing keeps contaminants from flowing from upper zones to lower zones (ie: from ground surface to water aquifer)
3. Cement is a protective sheath around casing.
4. Cement acts as a hydraulic seal.
5. Cement seals off "lose circulation" zones.

What is the difference between drilling and directional drilling?
Conventional Drilling is the drilling of a vertical well through reservoir rocks to TD. Directional drilling is the drilling of a non-vertical well horizontaly through a source rock.
What do oil driller do every day?
An drilling engineer may have many responsibilities. His work day may vary depending on the well or wells that need to be drilled. Generally, drilling engineers work in teams, with other engineers involved in the planning and the actual drilling of wells. No matter how much planning goes into drilling a well, every well is unique and has new challenges. So a drilling engineer is always learning how to drill a well better and safely. So, what activity can I say a drilling engineer does every day, is to communicate with others, to learn from past experiences and be prepared always for unexpected events.
Who invented horizontal well drilling?
Roland Matteri Petaluma Ca.
How is petroleum extracted?
Petroleum is extracted by different processes. 1. Drilling 2. Well Completion 3. Production System and facility design (Plant) 4. Storage or Shipment Drilling: It is first process in the petroleum extraction. The drilling is same like drilling for orifice in the wall, but it is large in scale. The machine that drill the well is called as " Drilling rig". The drilling rig has main four function. a. Rig Power System: Either by diesel engines or by electric engines b. Hoisting System: c. Circulating System d. Rotary system e. Well control system: By BOPs, like Pipe Ram, Annular Preventor, and Shear Ram etc. f. Well monitoring System:
What the importance of drilling center and guided drilling?
Drilling centre and guided drilling get your hole in precisely the correct place.

What type of services does Schlumberger provide to oil and gas companies?
The services that Schlumberger provide to oil and gas companies include well testing and directional drilling; well cementing and stimulation; flow assurance and consulting; and seismic acquisition and processing. Schlumberger is the world's largest oilfield services company.
What is the use of drilling fluid?
The use of drilling fluids as follows:Remove cuttings from wellSuspend and release cuttingsControl formation pressuresSeal permeable formationsMaintain wellbore stabilityMinimize formation damageCool, lubricate, and support the bit and drilling assemblyTransmit hydraulic energy to tools and bitEnsure adequate formation evaluationControl corrosionFacilitate cementing and completionMinimize impact on environment
What are casing and cementing services?
Casing and cementing services are provided when the well is drilled. Casing is a large steel pipe, inserted into the wellhole and cemented into place.
Why is it important to the depth of an aquifer before drilling a well?
It's important to know the depth of an aquifer before drilling a well because if you drilled 35ft but there was a remaining of about 5-10 more feet you wouldn't really get all the water from the aquifer, and you'd run out of water in an amount of time.
What is the function of drilling fluid?
The main functions of drilling fluids can be summarized as follows:Remove cuttings from wellSuspend and release cuttingsControl formation pressuresSeal permeable formationsMaintain wellbore stabilityMinimize formation damageCool, lubricate, and support the bit and drilling assemblyTransmit hydraulic energy to tools and bitEnsure adequate formation evaluationControl corrosionFacilitate cementing and completionMinimize impact on environment
Are there any careers in mud testing in the oil field?
Drilling mud is like blood of the drilling well without their ciculation drillling isn't possible, then u can imagin how much important its?
