A developmental drilling program involves drilling for oil and gas in areas with proven reserves to depths known to have been productive in the past. This often involves drilling additional wells in or adjacent to a field with established production.

Definition

A Developmental Drilling Program refers to a systematic approach to drilling in areas where oil and gas reserves have already been proven. The primary objective is to enhance production from existing wells or to drill new wells within the same field to the depth that has previously yielded hydrocarbons. This type of drilling aims to maximize the recovery of resources from known reservoirs and typically involves less risk compared to exploratory drilling due to the known presence of hydrocarbons.

Examples

  1. Additional Wells Drilling: In a mature oil field, new wells are drilled based on previous geological data, which indicates the presence of more hydrocarbons in untapped formations.
  2. Horizontal Drilling: Instead of drilling a new vertical well, a horizontal well is drilled from an existing vertical wellbore to access additional oil and gas in the same reservoir.
  3. Infill Drilling: New wells are drilled in between existing wells to optimize production and improve the recovery rate of the hydrocarbons trapped in the reservoir.

Frequently Asked Questions (FAQs)

What is the difference between exploratory and developmental drilling? Exploratory drilling involves drilling in areas where oil and gas reserves are not yet proven, which is generally riskier and costlier. Developmental drilling, on the other hand, takes place in areas with known reserves to enhance production from existing resources.

How do geologists determine the location for developmental drilling? Geologists use seismic data, well logs, core samples, and production history to identify optimal locations for developmental drilling that have a high probability of additional recoverable hydrocarbons.

Is developmental drilling always successful? While developmental drilling has a higher success rate compared to exploratory drilling, there are no guarantees of success. Technical challenges, changing economic conditions, or unexpected geological structures can impact the results.

What are proven reserves? Proven reserves are quantities of oil and natural gas that, through geological and engineering data, are reasonably certain to be recoverable from known reservoirs under existing economic and operating conditions.

What technologies are used in developmental drilling? Technologies like horizontal drilling, hydraulic fracturing, 3D seismic imaging, and smart well technologies are often used to maximize efficiency and recovery rates in developmental drilling.

  1. Proven Reserves: Quantities of petroleum that geological and engineering information suggests with reasonable certainty are recoverable in the future under existing economic and operating conditions.
  2. Exploratory Drilling: Drilling carried out to discover and delineate oil and gas reserves in areas where such deposits are not previously known or measured.
  3. Horizontal Drilling: A drilling technique where the well is turned horizontally at depth to access a larger portion of the reservoir.
  4. Infill Drilling: The practice of drilling additional wells between the existing wells to increase the extraction of hydrocarbons.
