PLANNING IS THE SEED FOR SUCCESSPLANNING IS THE SEED FOR SUCCESS

Without a plan, success will be difficult.

Planning defines the activities and describes how the activities will be accomplished. The purpose of plan is to define each task, estimate the time and resources required, and provide a framework for management review and control.

Planning is an iteration process

Terminology • Scope: of any project is a combination of all individual tasks and their goals.

• Activity They are a division of all the work that needs to be completed in order to accomplish the project goals.

• Resource is something that lies ready for use or that can be drawn upon for aid or to take care of a need. Can be people, equipment, materials or services that are needed to complete various tasks. The amount of resources affects the scope and time of any project.

• Risk is any factor that potentially can jeopardize the successful completion of a project.

• Risk Management is the art and science of identifying, analyzing, and responding to risk factors throughout the life of a project.

• Work Breakdown Structure is a division of tasks that define, organize, and display the work to be accomplished to achieve the specified product or services.

It is possible (and in some instances mandatory) to setup relationships for the planned Activity

The relationship options are illustrated here:

If no relationships are set the system assumes all activity will be start in start day of the project

(NOTE: Delays/overlaps between finish/start are possible)

• SS - start / start• FF - finish / finish• FS - finish / start• SF - start / finish

EXAMPLEA typical example of a Start / Start relationship would where work needs to be carried out on an offshore platform at sea level by boat. Rather than complete each task step sequentially, returning to shore each instance to pick up necessary resources, it would more beneficial carry out all task steps at the same time in a single trip – a start/start relationship.

Now that we have found a promising geological structure and acquired the petroleum rights, it is time to go ahead and drill. Regardless of all the sophisticated geological and geophysical mapping that has been done, the only way to find out if there is any oil or gas present underground is to drill a well.

Wildcat Well

Wildcat Well: well that drilled into a geologic structure in which no oil or gas has yet been discovered.

The objective of drilling is to bore a hole (the well bore) into the ground until you penetrate a target rock formation, that has been identified by the geologists and geophysicists as having the potential to contain commercial hydrocarbons.

Formations may contain fluids (oil, water or natural gas) at very high pressures, without taking the appropriate precautions, the fluids would come out of the hole and we'd have what's called a blowout.

Reserves Evaluation

How Big is our Oil or Gas Field?

• For in between the exploration phase and the development phase there is quite often one other phase: the delineation phase.

• After drilling only one well (the discovery well), Seismic data is very helpful in mapping the size of the underground structure, but the only way to be certain of what parts of the structure contain oil is to drill delineation or step-out wells. Each new well added more information about the field. This information was then used in planning the location of the next delineation well until finally there were enough wells to show the limits of the field.

• After a field has been discovered, it must be developed so that it can be put on production and generate some cash. Developing a field involves the drilling of additional wells to the geologic structure and installing production equipment throughout the field to facilitate commercial production of the oil or gas. The production phase essentially involves getting the oil and/or gas out of the ground, treating the fluids to remove impurities, and taking whatever steps are necessary to keep the wells producing at a profitable rate for as long as possible.

Definition of Reserves

Oil reserves are primarily a measure of geological risk - of the probability of oil existing and being producible under current economic conditions using current technology. The three categories of reserves generally used are proven, probable, and possible reserves.

• Proven reserves (P1) - defined as oil and gas "Reasonably Certain" to be producible using current technology at current prices, with current commercial terms and government consent- also known in the industry as 1P.

• Probable reserves (P2) - defined as oil and gas "Reasonably Probable" of being produced using current or likely technology at current prices, with current commercial terms and government consent - This is also known in the industry as 2P or Proven plus probable.

• Possible reserves (P3) - Possible reserves are those unproved reserves which analysis of geological and engineering data suggests are less likely to be recoverable than probable reserves. This is also known in the industry as 3P or Proven plus probable plus possible.
